What if the leaves of water lilies turn yellow and black? learn 6 tricks to solve easily / too little water and too much fat.

As a beautiful flower, water lilies are often potted at home by flower friends, and the beauty of flowering is really unforgettable. However, in the process of breeding, water lilies will have great problems due to various reasons, such as water lilies turn yellow, water lilies turn black, and so on. What about the yellow and black leaves of water lilies? The following is a little bit of experience from the editor. Flower friends with this problem should take a look at it.

What if the leaves of water lilies turn yellow and black? find the reason.

Water lilies are hydroponic plants that many people like to raise, because they are not only beautiful, but also very easy to raise. However, if it is a stocking state, water lilies often show symptoms of yellowing and blackening of leaves. As for what to do when the water lily leaves turn yellow and black, the editor will explain separately.

(1) the leaves of water lilies turn yellow for two reasons.

There are actually many reasons for the yellowing of water lily leaves, but there are two main ones:

1. Too little watering / lack of water, the new leaves will wither and turn yellow. Solution: increase the number of watering times.

2. The air humidity is too small, and the dry environment is easy to cause the new leaves of water lilies to wither and turn yellow. When the air is dry, in addition to watering the water lilies, you should also spray water around them.

(2) the leaves of water lilies turn black for four reasons.

Water lily is a common aquatic plant. It is kept at home by many people because of its good-looking appearance. But in the process of raising, many flower friends' water lily leaves will turn black, how is this going on? As far as the editor knows, there are four reasons for this phenomenon:

1. Fertilize too much

There are many reasons for the blackening of water lily leaves, the most likely of which is too much fertilizer. In the growing period, if you apply too much fertilizer, the leaves of water lilies will be reduced, the ability to absorb water will decrease, and the leaves will turn black.

Solution: it is found that the leaves blackened by excessive fertilization, flower friends should immediately change the water, at this time to change half, to keep the water temperature close. If the base fertilizer is applied too much at the time of planting, it will need to turn the basin and change the soil again.

2. Infection of germs

In addition to fertilization, infection with bacteria is also one of the reasons for the blackening of water lily leaves. Once the water lily is infected with germs, not only the leaves will turn black, but also all kinds of problems will occur.

Solution: if you are infected with germs during the growth of water lilies, flower friends should cut off the blackened leaves and spray them with carbendazim solution.

3. Lack of light

In the planting method of water lilies, we put special emphasis on the importance of adequate light. Because once the light is too little, the leaves of water lilies will turn black, and in serious cases, it will cause decay.

Solution: lack of light, naturally to strengthen sunshine, it is best to ensure that there are 7-8 hours of sunshine every day.

4. The water quality is not clean

In addition to the above points, unclean water quality is also one of the reasons for the yellowing of water lily leaves. Because when the water is dirty, the leaves of water lilies tend to turn black.

Solution: if it is a water quality problem, it is very simple, we just need to replace it with clean water. Note: when changing water, you should pay attention to the water temperature so as not to change the pH of the water.

1. What are the benefits of growing flowers? With its gorgeous elegant demeanor, flowers decorate nature with extraordinary beauty and give people the enjoyment of beauty. Growing flowers can enrich and regulate people's cultural life, increase fun, cultivate temperament, improve health, increase scientific knowledge and improve cultural and artistic literacy. Growing flowers can afforest and beautify the land of the motherland, protect and improve, purify the air, so that people can work and study in a beautiful environment and live a better life. Growing flowers is not only for viewing, but also has a lot of important economic value. Flowers are an important part of Chinese herbal medicine. Honeysuckle, chrysanthemum, wax plum, hibiscus, rhododendron, rose and lotus are all commonly used Chinese herbal medicines. Fragrant flowers are widely used in food and light industry, such as sweet-scented osmanthus can be used as food spices and wine, jasmine, magnolia, generation, pearl orchid and other feasible smoked tea, chrysanthemum can make high-grade food and dishes. White orchid, jasmine, rose, wax plum, daffodil and other flavors can be extracted. Growing flowers can also be exchanged for foreign exchange and accumulate funds. For example, rose oil, an advanced essence extracted from roses, is called "liquid gold" in the international market, and its value is more expensive than gold. 2. What are the categories of flowers? China is known as the "mother of the world garden", rich in flower resources, a wide variety of flowers, in order to facilitate cultivation, management and utilization, it is necessary to understand the classification knowledge of flowers. Because the basis of classification is different. As a result, the methods of classification are different. According to the morphological characteristics of flowers, flowers are usually divided into two categories: herbaceous flowers and woody flowers. Herbaceous flowers with soft stems and woody stems are called woody flowers. According to the growth habits and morphological characteristics of flowers, they can be divided into herbaceous flowers, woody flowers, succulent flowers and aquatic flowers. Herbaceous flowers can be divided into annual and biennial flowers, perennial flowers, bulbous flowers and lawn plants according to their growth and development cycle. Woody flowers can be divided into trees, shrubs and vines according to their trunk height and crown size. Succulent flowers, with fleshy thick stems and leaves, the body is rich in water, some leaves degenerated into needles or feathers, strange shape, so in horticulture into its own category. Aquatic flowers grow in water and marshes all the year round, and most of them belong to perennials. According to the classification of ornamental parts, flowers can be divided into ornamental flowers (mainly ornamental flower color and flower shape, such as chrysanthemum, rose, etc.), foliage (mainly ornamental leaf color, leaf shape, such as variable leaf wood, flower and leaf taro, etc.), fruit ornamental (mainly ornamental fruit, such as kumquat, etc.), ornamental stem (mainly ornamental branch and stem, etc.) Such as single trees, mountain shadow boxing, etc.) and ornamental buds (mainly ornamental buds, such as silver willow). According to the use, flowers can be divided into cut flowers (such as carnation, calla lilies, etc.), indoor flowers (such as orchid, tortoise back bamboo, etc.), courtyard flowers (such as rose, chrysanthemum, etc.), medicinal flowers (such as peony, honeysuckle, etc.), spice flowers (such as blue orchid, jasmine, rose, etc.) and edible flowers (lily, golden needle, pomegranate). 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, subcold flowers, alpine flowers and so on. This classification can reflect the habits of all kinds of flowers and the conditions for their growth and development during cultivation. 3. What are bulbous flowers?

Bulb flowers are perennial herbaceous flowers with abnormal underground stems or roots, which are spherical or shaped. According to the morphological structure of its underground stem or root, it can be divided into five categories: (1) bulbs. The underground stem is scaly. Those with a papery outer skin are called skinny scales such as tulips, daffodils, Zhu Dinghong, etc., and those without an outer covering on the scales are called skinless bulbs, such as lilies. (2) corms. The underground stem is spherical or oblate, and the outer skin is made of leather, such as gladiolus, chamomile and so on. (3) Rhizome. The underground stem is hypertrophic and root-shaped, with obvious nodes above, and new buds are born at the top of the branches, such as canna, ginger, lotus, water lilies, hairpins and so on. (4) tubers. The underground stem is irregular block or strip, such as calla lily, cyclamen, paulownia, evening jade and so on. (5) block root class. The underground main root is hypertrophic and massive, and the root system grows from the end of the root tuber, such as Dahlia.

Temperature is an important condition for the survival of all kinds of flowers. No matter how suitable other environmental conditions are, it will be difficult for flowers to survive without suitable temperature conditions. The growth and development of each kind of flower has its optimum temperature, highest temperature and lowest temperature. According to the temperature of the origin of flowers, flowers can be divided into high temperature, medium temperature and low temperature. (1) high temperature. Such as Milan, poinsettia, melon leaf chrysanthemum, big rock tree, upside down hanging golden bell and so on. When cultured in North China, the lowest room temperature should be kept above 12 ℃ in winter. (2) medium temperature. Such as Magnolia, jasmine, Fusang, geranium and so on, the room temperature in winter should not be lower than 5 ℃ (3) low temperature. Such as oleander, sweet-scented osmanthus, kumquat, generation, cycad, etc., winter room temperature is not less than 0 degrees. If the temperature is too high or too low, the normal physiological activities of flowers will be destroyed, the growth will stop, and in serious cases, the whole plant will die. 5. What is the effect of light on the growth and development of flowers? Light is the source of energy for flowers and plants to produce nutrients. without the existence of light, photosynthesis cannot be carried out, and the growth and development of flowers will be seriously affected. Most plants can blossom and flourish only in sufficient light. Different kinds of flowers have different requirements for light. Flower proverb: "Yin Camellia, Yang Peony, half Yin and half Yang four Seasons Orchid". According to the different light intensity requirements of flowers, flowers can be divided into positive flowers, neutral flowers and negative flowers. (1) positive flowers. Most flowers and fruits are positive flowers, such as Magnolia, rose, pomegranate, plum blossom, crape myrtle, citrus and so on. There are also a few positive flowers in foliage flowers, such as cycads, palms, variable-leaf trees and so on. Most aquatic flowers, cacti and succulent plants are also positive flowers. All positive flowers like strong light and are not resistant to shade. If the sunlight is insufficient, it is easy to cause the branches and leaves to grow, the tissue is soft and weak, the leaf color becomes pale and yellowish, it is not easy to blossom or is not good, it is vulnerable to diseases and insect pests, and (2) negative flowers. Grow well in shaded environment, such as asparagus, camellia, rhododendron, hairpin, green pineapple, evergreen, ivy, paulownia, tortoise back bamboo, begonia, etc., if exposed to strong light for a long time, the branches and leaves wither and yellow, growth stagnant, serious or even death. (3) neutral flowers. Grow well under the condition of sufficient sunshine, but there is no principle to add shade when the light intensity is strong in summer, such as sweet-scented osmanthus, jasmine, magnolia, eight immortal flowers and so on. To sum up, all kinds of flowers have different requirements for light and light, and even the same flower has different requirements for light at different stages of growth and development. positive chrysanthemums are required to form buds under short-day conditions. 6. What is the effect of light on flower bud differentiation? The purpose of cultivating flowers is to make them produce more flowers, and light is the most effective external cause to promote flower bud formation. On the same flower, there are many flower buds on the branches that are fully exposed to light, and there are few flower buds on the branches that do not receive enough light. When there are many sunny days in summer, flowers receive plenty of light, and there will be more flowers in the coming year. Generally speaking, flowers and plants can carry out photosynthesis at a temperature of 10-35 ℃, and the most suitable temperature is 20-28 ℃. According to the requirements of sunshine time, flowers can be divided into three categories: (1) long sunshine flowers. Generally speaking, the sunshine time every day needs more than 12 hours to form flower buds, which is called long sunshine flowers. Many flowers that bloom in spring and summer, mostly belong to long sunshine flowers, such as iris, chrysanthemum, impatiens and so on. (2) short sunshine flowers. Flowers that spend less than 12 hours of sunshine every day to form flower buds are called short-day flowers. Poinsettia and chrysanthemum are typical short-day flowers, they can only grow under long sunshine in summer, but can not carry out flower bud differentiation. After autumn, flower bud differentiation begins when the light is reduced to 10-11 hours. (3) medium Rizhao flowers. Flowers whose flower buds are not strict with the daytime sunshine are called Zhong Rizhao flowers. Such as calla lily, carnation, hundred-day grass, rose, Fusang, etc., they have no obvious response to the length of light time, as long as the temperature is appropriate, they can blossom all the year round.

Practical Collection of Family Flower cultivation (part I) 7. What is the effect of water on the growth and development of flowers?

Water is a necessary condition for the growth and reproduction of flowers. It has a great influence on the growth and development of flowers. Because water absorption exceeds consumption, too much water in the flower body, the plant is extra-long and weak, cold resistance decreases, and stress resistance weakens. If there is too much water for a long time, it will cause rotten roots, fallen leaves, and even death. Water absorption is less than consumption, due to lack of water, flowers wilt phenomenon, serious lack of water will make flowers die. There are many kinds of flowers, and the water demand is also different, that is, the same kind of flower has different water requirements in different periods of its growth. According to the different water demand of flowers, flowers can be divided into three types: xerophytic, aquatic and mesophytic: (1) xerophytic flowers. Such as plum blossom, crape myrtle, Xifu begonia, hollyhock, southern bamboo and succulent flowers are more drought-resistant. (2) Aquatic flowers. Such as lotus, water lily, calamus, water bamboo and so on. (3) mesophytic flowers. Flowers that grow well in moist soil. Most flowers belong to this type, such as magnolia, magnolia, wax plum, peach blossom, camellia, bauhinia and so on.

8. What is the effect of air humidity on flowers?

Most of the water needed by flowers comes from the soil, but the air humidity also has a great influence on the growth and development of flowers. If the air temperature is too high, it is easy to cause branches and leaves to grow, petals moldy, falling flowers, and easy to cause the spread of diseases and insect pests. The humidity in flowering period is too high, which hinders flowering, affects fruiting and so on. If the air humidity is too small, the florescence will be shortened and the color will be lightened. If the air is dry for a long time, it will grow badly and affect flowering and fruiting. Northern winter climate is dry, indoor flower cultivation, such as do not often maintain a certain humidity, some like wet flowers, often appear yellowish leaves, leaf edges dry and so on. According to the different requirements of air temperature for different flowers, methods such as spraying and washing branches and leaves or covering with plastic film can be adopted to increase air humidity and create humidity conditions suitable for their growth. Orchids, begonias, tortoise-backed bamboos and other wet flowers require that the air relative humidity is not less than 80%; jasmine, white orchids, mulberry and other medium-wet flowers require air humidity not less than 60%.

9. Why do too many flowers die?

When the potted flowers are watered too much, the water fills the soil gap, and the air in the soil is replaced by water, so the external air can not enter, which results in soil anoxia, hindrance of root respiration, decrease of physiological function and hindrance of root water and fertilizer absorption. At the same time, due to the lack of oxygen in the soil, a large number of aerobic bacteria with the function of decomposing organic matter in the soil multiply and move, which increases the acidity of the soil. Due to the extensive activities of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia were produced, which directly poisoned the root system. At the same time, because the anoxic plants consumed a large amount of soluble sugar and accumulated too much alcohol and other substances, the photosynthesis was greatly reduced, and finally the flowers died of hunger. In the practice of flower cultivation, we can often see examples of flowers being "drowned" due to overwatering, resulting in blackening and decay of flowers' roots. Therefore, we should pay attention to the right amount of watering when cultivating flowers.

Practical Collection of Family Flower cultivation (part I) 10. What is the harm of insufficient watering of 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 there is a long-term insufficient water supply to the flowers, the leaves of the older and lower parts of the plant 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.

11. 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. 12. Why not use cold water to water flowers at noon in midsummer? At noon in midsummer, the temperature is very high, and the temperature on the leaf surface of flowers can often be as high as 40 ℃. The transpiration is strong, and the water evaporation is also fast. The root system needs to absorb water constantly to supplement the loss of transpiration. If cold water is poured at this time, although water is added to the basin soil, due to a sudden drop in soil temperature, root hairs are stimulated by low temperature, which will immediately hinder the normal absorption of water. At this time, due to the lack of any preparation in the flower body, the foliar stomata were not closed, and the water lost the balance of supply and demand, which led to the thin foliar surface from tense state to wilting, resulting in "physiological drought" of the plant, scorched leaves, and serious death of the whole plant. This phenomenon is particularly obvious in herbaceous flowers, such as geranium, pineapple, chrysanthemum and so on. For this reason, it is appropriate to water flowers in the morning and evening in summer.

Practical Collection of Family Flower cultivation (part I) 25. How does the family carry out soilless cultivation? Family soilless cultivation can be cultivated in common pots such as plastic pots and plain baking pots. When planting, all kinds of substrates are mixed in proportion or put separately into a plastic basin, and then the seedlings with 3-5 leaves are planted in the center of the pot. Before planting, put the root system with soil in clean water, wash the root mud gently, and then soak the root in a solution 5 times thinner than the normal concentration of nutrient solution for about 10 minutes, so that it can fully absorb nutrients. After planting, cover it with a layer of quartz sand or pebbles to fix the plant, and immediately pour 0.5 times of the nutrient solution from around the container until there is a nutrient solution flowing out of the drainage hole at the bottom of the basin. After that, water was irrigated every 1-3 days, dilute nutrient solution was irrigated once in 7-10 days, and normal concentration of nutrient solution was poured after the plant returned to normal growth. The number of times and number of nutrient solution irrigated depends on the type of flowers, plant size, different growth stages, seasons and placement locations. In general, during the growth of indoor potted flowers, large seedlings are irrigated with nutrient solution every 7 to 15 days, seedlings are watered every 15 to 20 days, and flowers are watered once a month during the dormant period. The number of nutrient solution each time, the general flowerpot inner diameter of about 20 cm of positive flowers, each time about 100 ml, the amount of negative flowers should be reduced. If long-acting flower fertilizer is used, its dosage should refer to the provisions of the product manual. For beginners, pay attention to the right amount when pouring nutrient solution, preferring less than too much. If it is applied too much, it is easy to cause harm such as scorched leaves. Soilless cultivation of flowers, in addition to pay attention to grasp the time and amount of nutrient solution, but also according to the water requirements of different kinds of flowers timely watering, in order to keep the matrix often moist, in order to make flowers grow healthily. In order to avoid the loss of nutrient solution, it is best to choose a watertight container. The container that is more suitable for family use consists of two parts, the top is a flowerpot with a substrate (the bottom is porous), and the seedlings are loaded into it, and the top is a watertight container containing nutrient solution. When planting in this kind of container, the root system of the plant should be watered properly before extending into the nutrient solution, and a small amount of dilute nutrient solution should be irrigated every 5-7 days, and then transferred to normal management after the root system extends into nutrition. According to the growth habits of flowers, add nutrient solution and water regularly, generally change the nutrient solution thoroughly once a month, and wash the container containing the nutrient solution. At ordinary times, the amount of nutrient solution in the container is about 2 to 3 of the depth of the container. If you install too much, do not leave gaps, so that all the roots are soaked in the nutrient solution, the air is insufficient, and it is often easy to cause rotting roots due to hypoxia. The maintenance and management of flowers cultivated in soilless culture is basically the same as that of soil cultivation, and it is also necessary to give suitable environmental conditions such as light, temperature and humidity according to the habits of flowers. 26. What are the commonly used fertilizers? There are two types of fertilizers commonly used: (1) organic fertilizers. It is usually divided into animal organic fertilizer and plant organic fertilizer. Animal organic fertilizer includes human feces and urine, feather hoof horns and bone meal of livestock, wastes of fish, meat, eggs and so on. Plant organic fertilizer includes bean cake and other cake fertilizer, sesame sauce dregs, weeds, leaves, green manure, Chinese herbal medicine dregs, distiller's grains and so on. These two kinds of fertilizers are late-acting fertilizers with complete nutrients and long fertilizer effect, which can only be applied after fermentation and ripening before use. (2) Inorganic fertilizer. It is a fertilizer rich in mineral and nutrient elements, which is made by chemical synthesis or processed by natural ore. For example, nitrogen fertilizer includes urea, ammonium sulfate, ammonium chloride, ammonium nitrate and so on. Phosphate fertilizer includes calcium superphosphate, phosphate rock powder and so on. Potash fertilizer includes potassium chloride, potassium sulfate and so on. The fertilizer effect of chemical fertilizer is fast, but the fertilizer content is simple; the fertilizer is violent, but not long-lasting. Except for phosphate fertilizer, general chemical fertilizer is used as topdressing. 27. How to make your own fertilizer? In daily life, there are many wastes that can be used to make fertilizer. (1) soaking liquid fertilizer. Put waste vegetable leaves, melon peel, chicken and fish into the water, fish scales, waste bones, eggshells and moldy food (peanuts, melon seeds, beans, bean powder *) in a small jar (or small jar). Add water and sprinkle a little trichlorfon and cover it strictly. After high temperature fermentation, it can be used. When in use, the supernatant is diluted with water before it can be applied. The above waste can be mixed with some old culture soil, add some water, put it in a large plastic bag, place it tightly for a period of time, and use it after fermentation. (2) waste composting. Choose a suitable place to dig a pit with a depth of 60 cm ~ 80 cm and cover with 10 cm furnace ash. Put rotten vegetable leaves, livestock offal, fish scales, chicken and duck droppings, eggshells, meat waste and broken bones into the pit, sprinkle some pesticides, and cover it with a layer of garden soil about 10 cm thick. Keep the pit moist to promote fertilizer maturity. It is best to compost it in autumn and winter, and when it is heated and mature without malodorous gas in spring, it can be mixed into culture soil as base fertilizer; 4mm sieve can also be used to sift and rub into pellets while wet, fine as topdressing and coarse as base fertilizer.

28. How to avoid and reduce the stench from composting and fertilization? When there is accumulated fertilizer in retting, it often gives off an unpleasant smell and pollutes the environment, which is very unsanitary and unpleasant. Here is a brief introduction of some experiences to avoid or reduce the stench when retting fertilizer. (1) put a few pieces of orange peel (both dry and fresh) in the retting fertilizer container to reduce the odor. Because orange peel contains a lot of essential oil, the smell can be reduced by constantly volatilizing the fragrance with the fermentation process of fertilizer. When the effect of orange peel decreases, you can continue to put in a few new pieces of orange peel. Orange peel is also a good fertilizer after fermentation, which can increase fertilizer efficiency. (2) use kimchi altar to rett fertilizer. Put household non-staple food waste, such as rotten eggs, animal offal, bad milk, soy milk, etc., into the pickle jar, add an appropriate amount of water, pay attention to fill the jar sink with water, add some insecticidal drugs, and buckle the lid to prevent the stench from spreading. It can mature in about 2-3 months in summer. When it is used, the supernatant is added 10 times to 20 times of water, and a little trichlorfon and other pesticides are added to the fat water to prevent maggots. According to a material introduction, adding an appropriate amount of 500 × 600 times rice vinegar diluent before fertilizer and water application can alleviate the odor of liquid fertilizer. twenty-nine。 How to make fertiliser and water?

Huanling flower growers in Henan Province have used "alum fertilizer water" to irrigate flowers that like acid soil, and the effect is good. Common preparation methods: 20 kg-25 kg of water, 1 kg-1.5 kg of cake fertilizer or hoof slices, 250 g-300 g of ferrous sulfate (black alum), put the above materials into the tank and place them in the sun for about 1 month. The supernatant can be diluted with water. The soil irrigated with this kind of water shows a slightly acidic reaction, and the PH value is about 5.8-6.7.

thirty。 How can we achieve reasonable fertilization? The so-called rational fertilization means that we should pay attention to timely and appropriate amount. The so-called timely, refers to flowers when needed, if found that the color of flower leaves become light, plant growth is weak, fertilization is timely. As for when to apply what fertilizer, it depends on the different growth and development stages of flowers, such as more nitrogen fertilizer can be applied at the seedling stage to promote the rapid and robust growth of seedlings; more phosphate fertilizer can be applied at the bud stage to promote large flowers and seeds; fertilization can be properly controlled at the initial stage of fruit setting to facilitate fruit setting. No matter what period of fertilization should be paid attention to the right amount, if the application of too much nitrogen fertilizer, easy to form overgrowth; too much potassium fertilizer, hinder growth, affect flowering and fruiting. When applying fertilizer, we should pay attention to the following points: (1) We should pay attention to the kinds of flowers when applying fertilizer. Different kinds of flowers have different requirements for fertilizer. For example, sweet-scented osmanthus and camellia like pig manure and avoid human feces and urine; southern flowers such as rhododendron, camellia and gardenia avoid alkaline fertilizers; flowers that need to be re-cut every year need to increase the proportion of phosphorus and potassium fertilizer to facilitate the germination of new branches; flowers dominated by foliage can pay more attention to nitrogen fertilizer; flowers with large flowers (such as chrysanthemum and dahlia, etc.) need to apply an appropriate amount of complete fertilizer during flowering in order to make all flowers bloom and look beautiful. For flowers that mainly watch fruit, fertilizer and water should be properly controlled in the flowering period, and sufficient complete fertilizer should be applied in the strong fruit stage in order to achieve the desired effect; bulb flowers, apply more potash fertilizer to enrich the bulb roots; fragrant flowers, enter the flowering stage, apply more phosphorus and potash fertilizer to promote the strong smell of flowers. (2) fertilizing should pay attention to the season. Winter temperature is low, plant growth is slow, most flowers are in a state of stagnant growth, generally do not apply fertilizer; spring and autumn are in the peak period of flower growth, root, stem, leaf growth, flower bud differentiation, young fruit expansion, all need more fertilizer; summer temperature is high, water evaporation is fast, it is also a peak period of flower growth, the concentration of topdressing should be small, the number of times can be more. (3) the application of organic fertilizer must be fully mature, and raw fertilizer should not be used. In addition, there are many valuable opinions on how to fertilize potted flowers. For example, data from Jiangsu and other places point out that fertilization depends on growth, fixed amount, and adhere to the "four more, four less, four no", that is, more application of yellow and thin, more application of pregnant buds before germination, more application of pregnant buds, more application after anthesis, less application of sturdiness, less application of germination, less application of flowering, less application in rainy season, no application of only growth, no application of new planting, no application of summer heat, no application of dormancy. At the same time, it is also pointed out that there are three taboos in potted flower fertilization: first, avoid thick fertilizer, second avoid hot fertilizer (high soil temperature at noon in summer, fertilization is easy to hurt roots), third avoid sitting fertilizer, apply basic fertilizer at the bottom of the pot when planting flowers, and not put the root directly on the fertilizer, but add a layer of soil to the fertilizer. Then plant the flowers in the pot.
