Synadenium


Synadenium (Synadenium) is another representative of the Euphorbia family. This ornamental leafy plant is native to South Africa. Sinadenium belongs to succulent shrubs. Sometimes it reaches a fairly large size. It has wide oval leaves, green, dark red, milky juice is released on the cut.

For growing in private apartments and houses I use Synadenium Grant, which is unpretentious in terms of growing and care. This species is characterized by rapid growth. Frequent pinching will allow you to achieve a branched bush on your windowsill.

Sinadenium Granta is an evergreen shrub that grows to a height of about 3 meters. It has juicy fleshy stems, at first green, then forming a crust on the surface, similar to a woody one. It blooms with small dark red flowers. The inflorescence is at the top of the peduncle. But in the conditions of apartments and private houses, the flowering of the synadenium is practically not observed.

Home care for the synadenium

Location and lighting

To grow synadenium, you will need bright, diffused light. Its location on the east and west windows would be ideal. If the synadenium does not receive enough light, then its leaves will quickly lose their decorative effect.

Temperature

During the period of plant growth, the ambient temperature should be at least 23-25 ​​degrees. During the dormant period in winter, it should not be less than 12 degrees. In winter, the synadenium also needs bright, diffused light.

Air humidity

Sinadenium feels great both in a room with high air humidity and in a room with dry air. The only condition is regular care of its leaves, which consists in erasing accumulated dust from their surface.

Watering

In the spring and summer, it is important to water the synadenium as the topsoil dries out. If the ground dries up, the plant will begin to shed its leaves. In winter, watering should be reduced, since the plant is dormant during this period. For irrigation, use soft, settled water at room temperature.

The soil

The substrate for planting synadenium should be with a neutral acidity level (pH 5-7). A mixture of peat and leaf soil, sand with the addition of brick chips and charcoal is ideal.

Top dressing and fertilizers

Sinadenium is fertilized from spring to autumn with universal means for decorative deciduous plants. The frequency of top dressing is 2-3 times a month.

Transfer

A young plant needs an annual transplant, and an adult one every 2-3 years. The synadenium is transplanted only in the spring. At the bottom, you need to place a drainage layer of expanded clay, which prevents stagnation of water in the pot.

Pruning

In order for the plant to be lush and form many shoots, it is regularly pinched and pruned. This can be done throughout the year.

Reproduction of the synadenium

For reproduction of the synadenium, cuttings are used. In the spring, the cut stems are dipped in warm water so that the milky juice stops, then they are dried in the open air for a day and only then are planted in the substrate.

Growing difficulties

If leaves suddenly began to fall on the plant, then this may indicate insufficient lighting, improper watering, low air temperature.

Important! When working with synadenium (transplant, pinching), it is important to take precautions and work only with protective gloves, since synadenium juice is poisonous and can cause inflammation or allergic reactions if it comes into contact with the skin.

Optimization of the living environment in childcare facilities using plants

For centuries, people have tried to decorate and equip their homes with plants. In today's noisy, fast-paced and polluted world, the role of plants has increased many times over. It is especially great in cold climates, where a person spends most of his time indoors and is deprived of the opportunity to communicate with wildlife. Under these conditions, the normal development and health of children largely depend on the quality of the indoor environment - schools, kindergartens, etc. Protecting themselves from dust and noise, modern rooms are becoming more airtight and the concentration of potentially dangerous fumes in them increases. Indoor air contains tens and hundreds of harmful substances, including highly toxic ones, the concentration of which often exceeds the permissible level. Indoor risk factors include pathogenic microflora and chemical xenobiotics emitted by building and finishing materials, furniture or coming from outside. In addition, a long stay in closed rooms also increases the psychological stress on the child's body. Of course, the optimization of the ecological situation in closed rooms can be carried out with the help of technical cleaning systems and the introduction of waste-free technologies, but even the most advanced devices cannot provide a healthy environment everywhere. Reducing risk factors can be achieved by means of landscaping, it is quite effective to use some ornamental plants for these purposes. They can not only provide comfortable conditions for the internal environment of schools and preschool institutions in accordance with existing environmental standards, but also take into account those requirements for modern educational activities that relate to the educational space as a whole. The use of plants for this purpose is multifaceted.

The first, the most ancient, the generally accepted and stable function of plants is to create a favorable psychological environment. Plants are able to give a unique look to any room when included in the interior. Plant habit and colors are now widely used in phytodesign. When creating a unified interior style, not only the combination of furniture and wallpaper is taken into account, but also decorative elements and the color of flowers and leaves of plants. For example, leaves of unusual tones - purple and gray-gray - have a stimulating effect, and light or dark green ones have a calming effect and create a feeling of lightness (Kuznetsov, 1998). The effect of color has been repeatedly confirmed by numerous experiments by physiologists and psychologists. There are the following descriptions of the effect of color on the psyche (Table 1).

The influence of color on the human psyche

Creates a feeling of spaciousness, lightness. Accelerates blood pulsation. Dilates the pupils.

Toning, physiologically optimal, least fatiguing stimulates vision, accelerates blood pulsation, creates a feeling of warmth. It has a stimulating effect on the brain and is therefore effective for mental disabilities.

It dilates the pupils and accelerates the blood pulsation without affecting the blood pressure. It has a strong stimulating effect, creates a feeling of well-being and fun, a feeling of warmth and vigor, but can be tiring.

Creates an impression of warmth, excites, accelerates blood pulsation, dilates the pupils, accelerates the respiratory rate, with prolonged exposure leads to fatigue, has an irritating effect. Stimulates the brain, effective in melancholy.

It combines the effect of red and blue colors, it has a good effect on the vascular system, increases tissue endurance, affecting the heart, lungs and blood vessels. Increases the efficiency of mental work. But it produces a depressing effect on the nervous system: it causes a feeling of fatigue, heaviness, tightness.

Strong antiseptic, helps with inflammation of the upper respiratory tract, has a beneficial effect on the body in case of nervous disorders and insomnia. It causes a feeling of coldness, tightness, coils sadness, soothes, but the calming effect turns into a depressing one. Promotes inhibition of the functions of human physiological systems.

Provides a feeling of coldness and calmness

The most common for the organs of vision - physiologically

optimal analgesic, hypnotic. Affects the nervous system, relieving irritability, insomnia, fatigue. It causes a feeling of coldness, soothes, lowers the pressure inside the eye, lowers blood pressure, normalizes the work of the cardiovascular system, soothes and raises the tone. Increases motor-muscular performance for a long time.

Provides a feeling of coldness and calmness

Cold, causes boredom, apathy.

Creates a feeling of tightness, stability, calm mood

It makes you feel cold, refreshes.

Thus, the inclusion of plants and other forms of living nature in the interior to enhance aesthetic properties and a certain color creates a psychologically favorable environment, develops a sense of beauty and contributes to a good mood.

Second important function Plants in children's institutions are also well known - this is an improvement in the microclimate by humidifying, ionizing the air, increasing the oxygen content and reducing the carbon dioxide content in the air, as well as some noise mitigation, which has a beneficial effect on the psyche. It is especially important to form the indoor environment during the heating season, when the air in most rooms is very dry, while the optimum humidity is 45 - 55%. In this case, especially large plants in large containers can significantly affect the increase in moisture. The appearance of plants is a good indicator of air humidity. Plants that make up for the lack of negatively charged oxygen ions ionize the air and improve well-being. For example, conifers.

Third function associated with the purification of indoor air from dust, harmful substances and pathogenic microorganisms. Indoor risk factors include pathogenic microflora and chemical xenobiotics emitted by building and finishing materials, furniture or coming from outside. Some ornamental plants are capable of absorbing and neutralizing xenobiotics and releasing phytoncides. If the dust is regularly washed off from the plants, then the air in this room will be on average 40% cleaner than in the same room without plants (with the same quality of cleaning). Plants with large leaves - monstera, palm trees, ficuses - are especially effective in retaining dust. Ecological and medical phytodesign - a modern scientific direction of health improvement and improvement of environmental conditions using phytoncides and gas-absorbing properties of plants, offers low-cost, safe and highly effective methods that have a healing effect (Tsybulya, Fershalova, 2000). Being essentially one of the branches of phytoergonomics, which arose at the junction of biology and medicine and develops the problems of using plants to restore and improve the working capacity of people (Grodzinsky, 1989), ecological phytodesign deals with the optimization of human life and activities by means of landscaping. It is urgent to study the possibilities of ornamental plants as phyto filters for cleaning the indoor air from formaldehyde and other compounds, since indicators of air quality in residential premises according to international standards are two chemical compounds - benzopyrene and formaldehyde, which are carcinogenic (Tsybulya, Rychkova, Dultseva, 2000 Seraya, Dultseva, Tsybulya, 2003). For example, as a result of experiments in 8 experimental species of the genus Ficus, a decrease in the concentration of formaldehyde from 10 to 50% compared with the control was revealed. The group of phyto-filter plants that absorb harmful gases from the air include such common species as crested chlorophytum, Benjamin ficus, and some species of the bromeliad family. In rooms located in ecologically unfavorable areas, after the installation of phyto filters, a decrease in the concentration in the air of the most common and dangerous substance, formaldehyde, is achieved by an average of 20-30% (Voronova et al., 1992, Tsybulya, Fershalova, 2000). In some plants, toxic substances, such as sulfur dioxide, ammonia, undergo detoxification, are involved in metabolism and undergo profound changes. The absorption properties of plants depend on their condition. In particular, moist leaves absorb gas 2-3 times more intensely than dry leaves. On the one hand, the pubescence of plants helps to remove dust from the atmosphere, but on the other hand, it inhibits the absorption of gases. There is also a direct relationship between the absorption of gas by leaves and temperature. At temperatures above 25 °, the intensity of gas absorption is, on average, two times higher than at 13 °. In addition, woody plants carry out gas exchange 3-10 times more intensively than herbaceous plants growing on the same area. Some plants, such as begonia, are especially sensitive to the presence of pollutants in the air (leaf edges dry out) and can serve as indicators of pollution (Blinkin and Rudnitskaya, 1981).

In addition to toxic substances in the indoor air, there are always microorganisms that can cause various diseases. Plants, on the other hand, emit volatile biologically active substances (or volatile phytoorganic substances LPOV) - phytoncides that affect pathogenic microorganisms. The mechanism of action of volatile phytoncides consists in various changes in microbial cells and viruses, weakening their activity (Grodzinsky, 1973) and do not allow microorganisms to create their own defense mechanisms. It is essential that there are no changes in the genetic apparatus of microorganisms, that is, phytoncides do not have mutagenic properties and do not contribute to the selection of resistant forms of bacteria. The mechanism of action of phytoncides is twofold: on the one hand, volatile excretions affect the pathogenic microflora, entering the human body directly through the respiratory system, on the other hand, acting on microorganisms that are released into the air by a sick person. The absence of allergic reactions allows this method to be recommended even to children with allergic diseases. (2001) developed a technique for studying the antimicrobial activity of volatile biologically active substances in intact plants. The antimicrobial activity of volatile excretions of 65 species from 27 plant families against gram-negative (Escherichia coli), gram-positive (Stachylococcus epidermidis) species of microorganisms and yeast-like fungi (Candida albicans) was studied (Tsybulya, Rychkova, Dultseva, 2000 Tsybulia 2002). It was shown that in the air under the influence of plant phytoncides, the total number of colonies of microorganisms decreases by more than 50%. Plant species with versatile phytoncidal activity can be recommended for all types of premises. These are tall aspidistra, Japanese aucuba, Fischer's begonia, Kalanchoe Daigremonta, Japanese cryptomeria, hybrid Coleus, Arabian coffee, laurel, sublime nephrolepis, delicious monstera, common ivy, three-striped sansevieria, lemon citrus (Tsybulya, 2003).

When placing plants, it is necessary to take into account the radius of the phytoncidal action of plants: bactericidal - up to 3 m, bacteriostatic (when bacteria do not die completely, but lose their ability to reproduce) - up to 5 m. Therefore, plants should be placed as evenly as possible. Recommended number of plants: for a room with a volume of 100 cubic meters. m - about 20 copies (Tsybulya, 2000). For effective cleaning, the area of ​​plant leaves in a room with a volume of 100 cu. m should be from 1.5 to 3 sq. m. Recommended norms: when arranging a winter garden, plants can occupy up to 40% of the area of ​​the room, phytocompositions (for example, in a living room,% of the area of ​​the room.Do not forget that the placement should provide favorable conditions for the plants themselves (light, humidity, temperature). (1973) notes that temperature has the greatest influence on the quantitative content of phytoncides. Its increase from 15 ° C degrees to 20-25 ° C leads to a significant increase in the amount of phytoncides in the air. The concentration of these compounds increases 1.8 times. Strongly affects the formation of phytoncides and illumination. A significant weakening of phytoncidal activity occurs during physiological depression, caused, for example, by a moisture deficit, a low level of nutrition. Thus, knowing the dependence of the intensity of the formation of phytoncides on the state and conditions of growing plants, it is possible to control this process.

Fourth function ornamental plants is to improve the health of a person in an urban environment. They enrich the air environment of the premises with biogenic substances that have a beneficial effect on the general condition of the body, contribute to the improvement of the upper respiratory tract and lungs, increase the body's immunity and its resistance to stress, improve sleep, treat nervous diseases, increase efficiency and tone (Tsybulya, Fershalova, 2000) ... Plants, the volatile secretions of which improve cardiac activity, increase immunity, have a calming, anti-inflammatory and other therapeutic effects include: common myrtle, medicinal rosemary, lemon, fragrant geranium, laurel and others. It should be borne in mind that improper use of plants can lead to negative effects.

Fifth function of ornamental plants is extremely relevant in the modern urbanized world when addressing the issues of improving the living environment by means of environmental education and training. The greatest role of plants in nature and human life is becoming more and more obvious, and there are fewer and fewer opportunities for real acquaintance with them. Therefore, it is very important to acquaint people with individual representatives of the plant world, with their practical use and cultivation conditions. In classrooms, where a large number of children visit every day, plants must be grown - one of the most important components of the comfort and health of public places. Plants can be used as a teaching tool to broaden your horizons, be observant, and develop plant care skills. The art of growing plants, composing compositions and bouquets, communicating with plants is an affordable psychotherapeutic tool. Public places and childcare facilities provide excellent opportunities for this. Everywhere you can arrange phyto-corners with a specially selected assortment of plants, exhibitions of common and rare plants from the collections of botanical gardens, gardening organizations, as well as individuals.

Places in the interior

Phytodesign must correspond to the functional purpose of the premises and its microclimatic regime. The forms of using the interior can be different. In the lobby, dining room or in the relaxation room, you can create cozy corners by growing woody plants, Japanese gardens from dwarf forms of fruit and conifers, and interior compositions. In classrooms and auditoriums, various wall and floor phytocompositions are possible, stationary and temporary (flower containers, vertical gardening, showcases, florariums, decorative lawn, suspended landscaping, microlandscape compositions, etc.). If there is sufficient space and other related conditions, a winter garden is ideal. One of the simplest and most effective in perception is the “green wall” (Kazarinova, 2001), in which plants are located mainly in a vertical plane.

The main interiors in children's institutions are classrooms, laboratories, corridors, offices, ceremonial rooms, halls, lobbies and lounges. Currently, many institutions pay great attention to indoor gardening as a means of improving the indoor environment. There are several groups of plants that can be recommended for use in children's institutions, educational institutions, however, within the limits of the possible assortment, plants should be collected indoors, the most diverse in shape, color, size of leaves and flowers (Kozupeeva et al. 1985). There are plants that are not recommended to be grown in rooms where there are children: either because of the toxicity of the juice, or because of the allergenic effect of the secretions of the leaves. For example, poisonous plants from the aroid family (large-rooted alocasia and spotted dieffenbachia), the euphorbia family (euphorbia and synadenium genera). Alocasia large-rooted tissue juice contains toxic substances - alkaloids and hydrocyanic acid. Plants of the genera Dieffenbachia and Aglaonema have very hot sap. In representatives of childbirth, euphorbia and synadenium, milky juice is very toxic, it is a strong skin irritant and carcinogen (causes tumors), causes redness and severe swelling of the skin, if the juice gets into the eyes, a person can go blind. In oleander, all parts of the plant are very poisonous, the smell of flowers can cause fainting. Plants with a pronounced allergenic effect include species of the genus plectrantus, primrose reverse conic, pelargonium (geranium). Some plants have thorns - agave, euphorbia, ponzirus (Kazarinova, Tkachenko, 2003).

And, nevertheless, despite all efforts, in many cases ornamental plants do not take root. There are several reasons for this. For landscaping, you should use a highly fertile soil of the appropriate composition. When growing plants in it, you should maintain it in a loose state, apply fertilizers in a timely manner, including trace elements. In some cases, poor lighting is the cause of poor plant growth. In this case, additional lighting must be provided for the plants. Dust should be regularly washed off the leaves of plants by spraying them with warm water from a sprinkler and, most importantly, proper watering should be carried out. These simple rules of regular plant care usually help to keep them healthy, which is reflected primarily in their appearance. We are talking about recommended common plants that do not belong to the group of rare or exotic. Table 2 below provides a list of plant species recommended for landscaping to improve indoor indoor living conditions. Plant names are mainly from (2001) and (1983).

A new approach to optimizing the internal environment in children's institutions requires knowledge of the conditions and characteristics of each room, that is, in essence, drawing up an ecological passport (state). The possibilities of each type of plant used for landscaping should also be studied. To reduce the risk, it is necessary to take into account all environmental factors and their influence on the development of the educational process.

Required conditions

In nature, orchids reproduce primarily by seeds. They are helped in this by pollinating insects that fly to flowers.

At home, for this procedure, it is necessary to establish a certain microclimate and create the most favorable artificial environment.

  • Recommended humidity values ​​are from 60% and above.
  • The optimum ambient temperature should be between 20 ° C and 25 ° C.

The mother plant, from which the vegetative parts are taken for division, must be healthy. It is prepared in advance:

  • feed
  • timely treated with insecticides and fungicides against disease and pests
  • closer to the planned date, they are sprayed with succinic acid, which activates the growth of green mass.


Growing at home

Immediately after purchase, the plant needs time to adapt to the new microclimate. At this time, everything is organized around it so as not to change its location later, not to expose it to changes in temperature and humidity. The main thing that the Daniel variety needs is the constancy of conditions.

Temperature

In nature, these trees grow in the middle of tropical forests, where it is warm and humid. They don't have to withstand the cold or the heat. The usual and most optimal temperature for a plant is considered to be + 20 ° C. At higher rates, you will have to additionally humidify the air around the flower.

Daniel cannot stand the cold. At + 15 ° C, it abruptly stops growing, drops the casting, and then dies.

The consequences of lower temperatures are irreversible for the plant. Even if moved to a warm place, it may never recover from cold stress. Any drafts are also destructive for this variety.

Humidity

The tropical climate is always characterized by high air humidity. In the conditions of an apartment, it is raised artificially. Regular spraying and even a cool shower will be a real salvation for the tree from urban drought, but you should be careful with watering.

You can put the flowerpot on a tray filled with water. An ideal option is to place a humidifier nearby. It is very beneficial for flower development, especially in hot summer. During the heating season, you can hang wet sheets on the batteries and change them as they dry.

Lighting

A tall tree requires a lot of light to "feed" its lush crown with it. Even in direct sunlight, it will not disappear, although on hot days it is better, nevertheless, to shade it.

In winter, the plant needs good lighting.

The east or west side is the best location for the flower, when there is enough light, but there is no risk of burns.

In winter, flower growers experience problems with tree maintenance due to lack of lighting in the room. It turns yellow, the leaves begin to fall off. In this case, you need to purchase a special phytolamp and light up the plant. It is not necessary to keep it turned on around the clock, it is better to provide a full 14-hour daylight hours.


Triangular spurge (synadenium) is a perennial shrub that causes many people to immediately either have a strong feeling of affection or dislike. Although not a cactus, this plant has sharp thorns that can hurt you. Triangular spurge is a strictly tropical plant. And if in the summer it will stand in your open air, be sure to monitor the temperature. As soon as it drops to 10 ° C, you will have to bring it into a warm room.


What problems can you face

When propagating an orchid, flower growers face some problems:

  • Decay of slices. This is often due to ignoring the disinfection of fresh wounds, which are carried out with activated carbon, wood ash or cinnamon powder.
  • The appearance of rot after dividing the bush. Often, a non-sterile instrument provokes the penetration of pathogenic microorganisms.
  • Weak withered sprouts. In most cases, this is caused by violations of the basic rules of care, when the required humidity, temperature and illumination are not maintained, watering is disturbed.
