It is not difficult to know the characteristics and growth habits of eight Immortals and to cultivate flowers and plants.

There were many kinds of hydrangea, and the conditions for cultivation were not very high. Therefore, as long as you master the basic characteristics of hydrangea, it is not difficult to cultivate it at all, and it is very beautiful when it blooms. It can be opened for many days indoors. When it blooms, it can make the indoor air very fresh.

For the cultivation of hydrangea must choose the right soil, to use black soft soil. In this way, hydrangea can take root and grow better. You can choose to go to the flower market to buy bagged black soil, which is very suitable for the normal growth of hydrangea. The price will not be very expensive, generally about 5 jin 3 yuan appearance.

In the temperature control must be well mastered, many people like to put flowers in outdoor culture. However, in many places at the end of autumn, the temperature is relatively low, so hydrangea must be placed indoors at such a time, and the temperature control is about 22 degrees. The temperature is controlled well so that hydrangea does not affect normal growth.

Small insects are often recruited during flowering, so pesticides must be sprayed. Do not use too much pesticides when using them. Excessive use of pesticides will also cause great damage to flowers. And do not spray water quickly after spraying pesticides, which will seriously affect the effect of pesticides. After about 2-3 days in the spray can be.

After a year of growth, the nutrients in the soil are not so sufficient, and the nutrient solution should be poured once a week to keep the hydrangea from affecting normal growth. Mastering these will make your hydrangea bloom more vigorously and grow a few pots at home that look beautiful.

1. What are the benefits of growing flowers?

Flowers with its brilliant style, the natural decoration is particularly beautiful, giving people the enjoyment of the United States. Flower cultivation can enrich and adjust people's cultural life, add fun, edify temperament, improve health, and increase scientific knowledge and improve cultural and artistic literacy. Flower cultivation can beautify the motherland, protect and improve, purify the air, so that people can work and study in a beautiful environment, and live a better life. Flowering, not only for viewing, but also has many important economic value. Flowers are an important part of Chinese herbal medicine, honeysuckle, chrysanthemum, Chinese plum, hibiscus, rhododendron, rose, lotus and so on are commonly used Chinese herbal medicine. Fragrant flowers are widely used in food and light industry. For example, osmanthus can be used as food spice and wine, jasmine, white peony, generation, pearl orchid and other feasible smoked tea leaves, chrysanthemum can be used for high-grade food and dishes. White orchid, jasmine, rose, wax plum, narcissus and so on can extract essence. Raising flowers can also be exchanged for foreign exchange and accumulate funds. For example, rose oil, a high-grade essence extracted from roses, is known as "liquid gold" on the international market, and its value is more expensive than gold. 2 What are the types of flowers? China is known as "the mother of gardens in the world". Flower resources are rich and varied. In order to facilitate cultivation, management and utilization, it is necessary to understand the classification knowledge of flowers. Because the classification basis is different. Therefore, the classification methods vary. According to the morphological characteristics of flowers, flowers are usually divided into two categories: herbaceous flowers and woody flowers. The soft stems are herbaceous flowers, and the hard stems are woody flowers. According to flower growth habits and morphological characteristics classification, generally can be divided into herbaceous flowers, woody flowers, succulent flowers and aquatic flowers. Herbal flowers according to their growth and development cycle, etc., can be divided into annual, biennial grass flowers, perennial flowers, bulbous flowers and lawn plants. Woody flowers according to its trunk height and crown size, etc., can be divided into trees, shrubs and vine flowers. Fleshy flowers, with fleshy stems and leaves, rich in water stored in the body, some leaves degenerate into needles or feathers, unique in shape, so in horticultural cultivation in its own category. Aquatic flowers, year-round growth in water, marshy areas, most of them perennial plants. According to the classification of ornamental parts, flowers can be divided into flower observation class (mainly ornamental color and flower shape, such as chrysanthemum, rose, etc.), leaf observation class (mainly ornamental leaf color and leaf shape, such as variegated leaf wood, mosaic taro, etc.), fruit observation class (mainly ornamental fruit, such as kumquat, etc.), stem observation class (mainly ornamental branch stem, such as bachelor tree, mountain shadow boxing, etc.) and bud observation class (mainly ornamental bud, such as silver willow). According to the purpose, flowers can be divided into cut flowers (such as carnation, calla lily, etc.), indoor flowers (such as clivia, turtle, etc.), garden flowers (such as rose, chrysanthemum, etc.), medicinal flowers (such as peony, honeysuckle, etc.), spice flowers (such as white orchid, jasmine, rose, etc.) and edible flowers (lily, day lily, pomegranate, etc.). In addition, according to the climatic conditions of the origin of flowers, according to the natural distribution, flowers are divided into tropical flowers, subtropical flowers, warm temperate flowers, temperate flowers, sub-frigid flowers, alpine flowers, etc. This classification reflects the habits of various flowers and the conditions for their growth and development that need to be met during cultivation. 3. What is the relationship between temperature and flower cultivation? Temperature is an important condition for the survival of all kinds of flowers. No matter how suitable other environmental conditions are, flowers cannot survive without suitable temperature conditions. The growth and development of each flower has its optimum temperature, maximum temperature and minimum temperature. According to the origin temperature of flowers, flowers can be divided into high temperature, medium temperature and low temperature. (1)High temperature category. Such as Milan, poinsettia, melons, pittosporum, fuchsia, etc. In North China, the lowest temperature in winter should be kept above 12℃. (2)Moderate temperature category. Such as white peony, jasmine, hibiscus, geranium, etc., winter room temperature shall not be lower than 5℃. (3)Low temperature category.

Such as oleander, osmanthus, kumquat, generation, cycad, etc., winter room temperature is not lower than 0 degrees can be. If the temperature is too high or too low, the normal physiological activities of flowers will be destroyed, the growth will stop, and the whole plant will die when it is serious.

4. What effect does light have on flower growth? Light is the energy source for flower plants to produce nutrients. Without light, photosynthesis cannot be carried out, and the growth and development of flowers will be seriously affected. Most plants can flourish only in sufficient light. Different types of flowers have different requirements for light. Flower proverb cloud: "Yin camellia, Yang peony, half Yin half Yang four seasons orchid." According to the different requirements of flowers for light intensity, flowers can be divided into positive flowers, neutral flowers and negative flowers. (1)Male flowers. Most flowers and fruits belong to positive flowers, such as magnolia, rose, pomegranate, plum blossom, crape myrtle, citrus and so on. There are also a few positive flowers in the flowers of the leaf category, such as cycas, palms, and variegated leaves. Most aquatic flowers, cacti and succulents are also male flowers. All male flowers like strong light, but do not bear shade. If the sun is insufficient, it is easy to cause excessive growth of branches and leaves, soft and weak tissues, pale yellow leaves, difficult flowering or poor flowering, and easy to suffer from diseases and insect pests. (2)Female flowers. In the shade of environmental conditions to grow healthy, such as asparagus, camellia, rhododendron, hairpin, green radish, evergreen, ivy, pittosporum, turtle, begonia, etc., such as long-term exposure to strong light will be withered branches and leaves, growth stagnation, serious or even death. (3)Neutral flowers. Under the condition of sufficient sunshine, it grows well, but in summer, when the light intensity is large, there is no principle to shade slightly, such as osmanthus, jasmine, white peony, hydrangea, etc. To sum up, all kinds of flowers have different requirements for light, and even the same kind of flowers have different requirements for light at different stages of growth and development. When seedlings need light, they can gradually increase, but positive chrysanthemum requires flower buds to form under short day conditions. 5. What effect does light have on flower bud differentiation? People cultivate flowers for the purpose of making it bloom more flowers, and light is the most effective external factor to promote flower bud formation. On the same flower, branches that receive sufficient light have more flower buds; branches that receive insufficient light have fewer flower buds. When summer sunny days, flowers receive sufficient light, flowers in the coming year on more. Generally speaking, flower plants can carry out photosynthesis at temperatures of 10-35 ° C, with the optimal temperature being 20-28 ° C. According to the requirements of flower on the length of light, flowers can be divided into three categories: (1) long-day flowers. Generally, the daily sunshine time needs more than 12 hours to form flower buds, which are called long-day flowers. Many flowers bloom in spring and summer, mostly belong to long-day flowers, such as iris, aster, impatiens and so on. (2)Short day flowers. Flowers that require less than 12 hours of sunshine per day to form flower buds are called short-day flowers. Poinsettia and chrysanthemum are typical short-day flowers. They can only grow under long days in summer and cannot differentiate flower buds. After autumn, when the light is reduced to 10-11 hours, flower bud differentiation begins. (3)Mid-day flowers. The flower bud formation is not strict with the length of daytime sunshine, which is called medium sunshine flower. Such as calla lily, carnation, zinnia, rose, hibiscus, etc., they do not have obvious response to the length of light time, as long as the temperature is right, they can bloom all year round.

6. What effect does water have on flower growth and development? Water is essential for the growth and reproduction of flowers. It greatly affects the growth and development of flowers. Because water absorption exceeds consumption, flowers have too much water, plants are long and thin, cold resistance decreases, and stress resistance weakens. If there is too much water for a long time, it will cause rotten roots, defoliation and even death. Water absorption is less than consumption, due to lack of water, flowers are wilting phenomenon, serious water shortage will make flowers die. There are many varieties of flowers, and their water requirements are also different, that is, the same kind of flowers, in different periods of their growth, the water requirements are not the same. According to the different water demand of flowers, flowers can be divided into three categories: xerophyte, aquatic and mesophyte: (1) xerophyte flowers. Such as plum blossom, crape myrtle, west house begonia, hollyhock, south sky bamboo and many fleshy flowers are more drought resistant. (2)Aquatic flowers. Such as lotus, water lily, calamus, water bamboo and so on. (3)A mesophytic flower. Flowers that grow well in moist soil. The vast majority of flowers belong to this type, such as magnolia, white peony, Chinese plum, peach, camellia, bauhinia and so on. 7. What effect does air humidity have on flowers? Most of the water needed by flowers comes from soil, but air humidity also has a great impact on the growth and development of flowers. If the air temperature is too high, easy to make branches and leaves long, petals moldy, flowers, and easy to cause the spread of pests. Excessive humidity during flowering period hinders flowering and affects seed setting. Air humidity is too small, will shorten the flowering period, color fade. South flower north raise, if the air is dry for a long time, it will grow badly, affect flowering and fruiting. North winter climate is dry, indoor flower cultivation such as not often maintain a certain humidity, some wet flowers, often appear yellow leaves, leaf edges dry and other phenomena. According to the different requirements of different flowers for air temperature, spray washing branches and leaves or covering plastic films can be used to increase air humidity and create humidity conditions suitable for their growth. Orchids, begonias, turtles and other hygrophilous flowers require that the relative humidity of the air is not less than 80%; jasmine, white orchids, hibiscus and other moderately humid flowers require that the air humidity is not less than 60%. 8 Why do flowers die when they are watered too much? Potted flowers are watered too much, water fills the soil gap, air in the soil is replaced by water, and external air cannot enter at this time, thus causing soil anoxia, root respiration is hindered, physiological function is reduced, root water absorption and fertilizer absorption ability are hindered. At the same time, due to the lack of oxygen in the soil, the aerobic bacteria with the function of decomposing organic matter in the soil multiply and move in large numbers, increasing the acidity of the soil. Due to the activities of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia are produced, which directly poison the roots. At the same time, due to hypoxia plants consume a large number of soluble sugar in the body and excessive accumulation of alcohol and other substances, the photosynthesis is greatly reduced, and finally the flowers die due to hunger. In the practice of flower cultivation, we can often see cases of flowers "drowning" due to excessive watering, resulting in blackening and rotting of flower roots. Therefore, attention should be paid to proper watering when cultivating flowers.

9. What is the harm of underwatering potted flowers? Potted flowers due to less soil, water storage is not much, in the flower growing season need to pay attention to often replenish water, in order to ensure the normal growth of flowers. If the water supply is insufficient, the leaves and petioles will shrink and droop, and the flowers will wilt. If the water supply to the flowers is insufficient for a long time, the leaves of the older plants and the lower parts of the plants will gradually yellowing and dry up. If most grass flowers are in a state of drought for a long time, the plants are short, the leaves lose their bright green luster, and even the whole plant dies. Some flower growers are afraid of excessive watering, watering "half-waist water" every time, that is, the amount of water can only moisten the topsoil, while the lower soil is dry, this watering method will also affect the root development of flowers, and there will also be the above-mentioned bad phenomena. Therefore, watering should be dry and wet, and it should be watered thoroughly. 10. How to judge whether potted flowers are short of water? Watering is a regular management of flower cultivation, and it is difficult to grasp whether the potted soil is short of water, so many flower friends often feel distressed about it. Here is a brief introduction to the experience of flower growers in judging whether there is a shortage of water. (1) percussion method. Gently tap the wall of the upper and middle part of the flowerpot with your fingers, if you make a crisp sound, it means that the pot soil is dry and needs to be watered immediately; if you make a dull dull sound, it means that the basin soil is wet and can not be watered temporarily. (2) visual method. Use your eyes to observe whether the surface color of the basin soil changes, such as when the color becomes lighter or grayish white, it means that the basin soil is dry and needs to be watered; if the color becomes dark or brown, it means that the basin soil is moist and can not be watered temporarily. (3) finger measurement. Gently insert your finger into the basin soil at a depth of about 2 cm to touch the soil. When you feel dry or rough and hard, it means that the basin soil is dry and needs to be watered immediately; if it is slightly moist, delicate and soft, it means that the basin soil is moist and can not be watered temporarily. (4) pinching and twisting. Twist the basin soil with your fingers, such as the powdered soil, indicating that the basin soil is dry and should be watered immediately; if it is sealed into flakes or aggregates, it means that the basin soil is wet and can not be watered temporarily. The above test methods are all based on experience, which can only tell people the general situation of the dry and wet basin soil. If you need to know the dry and wet degree of the basin soil accurately, you can buy a soil thermometer and insert the thermometer into the seal. You can see that the words "dry or wet" appear on the scale, and you can know exactly when to water. What kind of water should I use to water the flowers? Water can be divided into hard water and soft water according to the condition of salt. Hard water contains more salt, and it is used to water flowers, which often produces brown spots on the leaves of flowers and affects the ornamental effect, so soft water is suitable for watering flowers. Rain Water (or snow water) is the most ideal in soft water, because Rain Water is a kind of near neutral water, which does not contain minerals and has more air, so it is very suitable to water flowers. If Rain Water can be used to water flowers in rainy days, it is beneficial to promote flower assimilation, prolong cultivation years and improve ornamental value, especially flowers that like acid soil, prefer Rain Water. Therefore, Rain Water should store more of the best part of the rainy season for use. In northeast China, snow water can be used to water flowers, and the effect is also very good, but we should pay attention to put aside the ice and snow until the water temperature is close to room temperature before using it. If there is no Rain Water or snow water, you can use river or pond water. If tap water is used, it must be stored in a bucket (tank) for 1-2 days, so that the chlorine in the water can be volatilized and then used. Do not use washing water containing soap or washing powder or dishwashing water containing oil to water flowers. For mildly alkaline cactus flowers, it is not suitable to use slightly acidic leftover tea. In addition, attention should be paid to the temperature of the water when watering the flowers. Whether watering flowers in summer or winter, the difference between water temperature and air temperature is too big (more than 5 degrees) is easy to harm the root system of flowers. Therefore, watering flowers with water, it is best to put it in a bucket (jar) to dry for a day, and then use it when the water temperature is close to the air temperature.

12. How to master the amount of water for potted flowers? Whether the watering amount of potted flowers can be timely and appropriate is the key to the success or failure of flower cultivation. According to the local experience, the watering amount of potted flowers is determined according to the flower variety, plant size, growth and development period, climate, soil conditions, flowerpot size, placement location and other aspects. In general, wet flowers should be watered more, drought-loving flowers should be watered less; bulb flowers should not be watered too much; herbaceous flowers should have more water content and transpiration, and more water should be watered than woody flowers; flowers with large, soft, smooth and hairless leaves should be watered more than woody flowers; flowers with small leaves with waxy layer, hairy and leathery leaves should be watered less; they should be watered more in the peak growth period and less in the dormant period; the seedlings with large pots should be watered more, and those with small pots should be watered less. Water more in hot days, less in cold days, more in dry days, less in cloudy days, etc. For general flowers, the water supply of the four seasons is: the temperature rises gradually after the beginning of spring every year, flowers enter the peak period of growth, the amount of water is gradually increased. Watering in early spring should be carried out before noon. The summer temperature is high, the flower growth is exuberant, the transpiration is strong, the watering water should be sufficient. Summer watering should be carried out in the morning and evening. After the Beginning of Autumn, the temperature is getting lower and lower, and the flowers grow slowly, so less watering is appropriate. Winter temperature is low, many flowers enter dormancy or semi-dormant period, to control watering, pot soil is not too dry, do not water, so as not to water too much and rotten roots, leaves. Watering in winter should be carried out at 1-2 p.m. 13. What is the function of spraying water? Spraying water can increase air humidity, lower air temperature, wash off dust from plants and wash away pests, avoid scorching of young leaves and early withering of flowers, and keep plants fresh; especially some flowers that like shade and humidity, such as camellia, rhododendron, orchid, tortoise back bamboo, etc., often spray water on the leaves, which is very beneficial to their growth and development. Summer rain after sudden sunny or muggy at night, should also pay attention to spray water cooling to prevent disease. The amount of water sprayed should be determined according to the needs of flowers. Generally speaking, the water can evaporate soon after spraying water, and the amount of water sprayed is the most suitable. Seedlings and delicate flowers need more water spray, new pots and cuttings that have not yet taken root also need more water spray, tropical orchid flowers, Araceae and pineapple flowers need to be sprayed more often. However, some flowers are very sensitive to moisture, such as Tripterygium przewalskii, Baobao flower, begonia, etc., whose leaves have thick villi, and the leaves are not easy to evaporate after the water falls, so it is not suitable to spray water on the leaves. For blooming flowers, it is not appropriate to spray more water, otherwise it is easy to cause moldy petals or affect fertilization and reduce fruiting and fruiting rate. In addition, the leaf buds at the top of cyclamen tubers, the flower buds in the leaves of African chrysanthemum, and the false bulbs in the middle of the leaves of Cymbidium are all afraid of being wet. These parts are vulnerable after spraying water. 14. How to save flowers after wilting? Potted flowers, due to less water in the basin, forget to water, especially in summer leakage watering, often cause leaf wilting, if not saved in time, the time will often lead to plant wilting. If it is not saved properly, it will sometimes cause plant death. The right thing to do is to immediately move the flowerpot to the shade when you find the leaves wilting, spray some water to the leaves, and pour a small amount of water. Later, as the stems and leaves gradually return to straight and straight, and then gradually increase the amount of water. If too much water is poured at this time, the plant may die. This is because a large number of root hairs of flowers are damaged after wilting, so the water absorption capacity is greatly reduced. Only after giving birth to new root hairs can the original water absorption capacity be restored. At the same time, wilting makes the cells lose water. After meeting the water, the cell wall absorbs water first and expands rapidly, and the protoplast absorbs water after it, and the expansion rate is slow. If a large amount of water is poured suddenly at this time, the plasmolemma will be separated and the protoplast will be damaged. Thus causing the death of flowers.

15. What role does soil play in the growth and development of flowers? Soil is an important matrix for the cultivation of flowers, the material basis for the survival of flowers, and the main source of water, fertilizer, gas and heat for the growth and development of flowers. This is because soil is made up of minerals, organic matter, soil moisture and soil air. Minerals are the most basic substances that make up the soil, and they can provide a variety of nutrients for flowers. Organic matter can not only supply nutrients for flower growth, but also play an important role in improving soil physical and chemical properties and soil aggregate structure, as well as water conservation, water supply, ventilation, temperature stability and so on. Soil moisture is an indispensable material condition for flower growth. Soil air is not only the source of oxygen needed by flower root absorption and microbial life activities, but also an important condition for soil mineral further weathering and organic matter transformation to release nutrients. Scientific experiments have proved that the soil suitable for plant growth accounts for about 38% of the soil by volume, 12% of organic matter, 15% of soil air and 15% of soil moisture. According to data, the most suitable water content for the growth of general flowers and plants is 25% of the soil volume, and air also accounts for 25%. Because some people do not understand the above truth, when cultivating potted flowers, they do not change pots and soil for a long time, resulting in the deterioration of soil physical and chemical properties, poor ventilation and permeability, and lack of nutrient elements, resulting in poor growth of flowers, yellowing leaves, less flowering, or even no flowering. therefore, in order to raise potted flowers, we should pay attention to changing pots and changing soil at the right time. 16. What kind of soil is good for potted flowers? Potted flowers have more stringent requirements on soil than open-field flowers because their roots can only move in a very small range of soil. On the one hand, nutrients are required to be as comprehensive as possible, and the limited basin soil contains nutrients needed for flower growth; on the other hand, it requires good physical and chemical properties, that is, loose structure, strong water-holding capacity, suitable pH and good fertilizer retention. Because of this, when growing flowers, we should try to choose neutral or slightly acidic soil with good aggregate structure, loose and fertile, good water retention and drainage performance, and rich humus. This kind of soil is light in weight, large in porosity, well ventilated and rich in nutrition, which is beneficial to the root development of flowers and the healthy growth of plants. If flowers are planted in clayey soil with poor ventilation and permeability, or in pure sandy soil with poor nutrition and poor water and fertilizer conservation, or in alkaline soil, for the vast majority of flowers, it is easy to cause growth weakness or even death. However, the soil conditions mentioned above are not available in any kind of natural soil. Therefore, it is necessary to choose artificial culture soil for potted flower soil. This kind of culture soil is made by mixing more than two kinds of soil or other matrix materials according to the different growth habits of flowers and plants, in order to meet the needs of different flowers. 17. How to prepare the culture soil? There are many materials suitable for the preparation of culture soil, and the following are commonly used at present. (1) plain sandy soil. Most of them are taken from the beach. The drainage performance is good, but it has no fertility, so it is often used to mix with other culture materials to facilitate drainage. (2) Garden soil. Soil taken from the surface of a vegetable garden, orchard, etc. It contains certain humus and has good physical properties, so it is often used as the basic material of most cultured soils. (3) rotten leaf soil. It is made of fallen leaves, withered grass, etc. It is one of the main materials for preparing culture soil because of its high content of humus, strong water retention and good permeability. (4) Mud. There are two kinds of black mountain mud and Huangshan mud. It is formed by the long-term accumulation of fallen leaves of trees in the mountains. Black hill mud is acidic and contains more humus, while Huangshan mud is also acidic and contains less humus. (5) Peat soil. It is carbonized from peat moss. Due to the different stages of formation, it can be divided into brown peat and black peat. Brown peat is rich in organic matter and shows acidic reaction, while black peat contains more minerals and less organic matter, showing slightly acidic or neutral reaction. (6) Rice chaff ash. It is ash made from rice husk after combustion, slightly alkaline, containing potassium, good drainage and air permeability. (7) stable fertile soil. It is made of animal faeces, fallen leaves and other substances mixed with garden soil, sewage and other accumulation and retting, which has rich fertility. In addition, there are pond mud, river mud, coniferous soil, turf soil, rotten sawdust, vermiculite, perlite and so on, which are good materials for preparing culture soil. The preparation of culture soil should be flexibly mastered according to the growth habits of flowers, the properties of culture soil materials and local conditions. For general potted flowers, the commonly used proportion of culture soil is rotten leaf soil (or peat soil): garden soil: River sand: bone meal = 35RV 30vet 5, or rotten leaf soil (or peat soil), plain sand soil, rotten organic fertilizer, calcium superphosphate, etc., after sieving according to 5RV 3.5Vue 0.5. Most of the above culture soil is neutral or slightly acidic, which is suitable for most flowers. It is used for cultivating acidic flowers and trees such as camellia and rhododendron, which can be mixed with about 0.2% sulfur powder; flowers such as cactus can be cultivated, and about 10% of the peeling soil from the lime wall can be added. Explanation: there are different opinions on the suitable acidity and alkalinity of some flowers and trees, the above data are for reference only.

18. How to choose the type of flowers in the family: as the saying goes, "the elegant room should not be big, and the fragrance of the flowers is not much." Put some flowers and plants indoors, with green leaves and flowers, evergreen all the year round, it is really full of spring and vitality. Family planting and cultivation of flowers, generally based on potted plants. Due to the limitations of the conditions, do not plant too much, 10-15 pots is suitable. The selected flowers had better be foliage flowers, flowering flowers, fruit flowers, fragrant flowers, ornamental flowers and so on, so that the varieties will be rich and diverse. The number of family flowers should be small but good, and the selection of varieties should be reasonable according to the family's environmental conditions and personal preferences. (1) Indoor flower selection: indoor is an important activity place in people's life, so flowers should be selected according to the following requirements. Flowers should choose shady or shade-tolerant varieties, such as evergreen, orchid, tortoise back bamboo, hanging orchid, rubber tree, gentleman orchid and so on. Some flowering plants are mostly positive flowers, which should be placed in the sunny place when decorated indoors, and often move to the outside to absorb sunlight and rain. Flowers and trees with peculiar smell should not be put indoors, such as cloves, nocturnal incense and other flowers will make some patients have adverse reactions, and some patients with high blood pressure and heart disease will feel stuffy and uncomfortable after smelling these fragrances. The aroma of pine and cypress plants can reduce people's appetite, and it is not suitable to put too much and too long indoors. The leaves, stems and sap of some flowers are toxic and should be properly isolated indoors, especially to avoid contact with children. Poinsettia, five-colored plum, oleander, tiger thorn, overlord whip, Lycoris, and so on are all poisonous, but in fact they are less toxic, as long as leaves, branches, flowers and fruits are not casually picked. More attention should be paid to cultivation. The layout of the bedroom should be quiet, clean, elegant and comfortable.
