Question 1: How does a fleshy man named Qiuhua raise a fleshy man named Qiuhua? The picture of the fleshy man named Qiuhua has not been found on the Internet, so it is impossible to tell whether there is this breed. However, the basic trick of succulents is not to put them below 7 for a long time, and to protect themselves from the sun when they exceed 30 in summer. If it rains for many days, you'd better take it back and don't let it get wet all the time. Usually put it in a ventilated place to let it bask more and blow more. Pay attention to dry soil before watering. The soil is mostly breathable and hydrophobic sandy soil. Generally, succulents can grow well in 12-30. In terms of soil use, try to use loose, permeable and sandy soil.

Question 2: how to maintain potted chrysanthemums 1 and put them in pots?

16-20 can plant chrysanthemum seedlings with roots; In a centimeter-caliber mud pot, three tiles are placed at the bottom to block the drainage hole, but not the drainage. Then some culture soil (which can be composed of 40% garden soil, 30% green chaff and 30% decomposed chicken house manure, or 70% garden soil and 30% green chaff ash) is added, and chrysanthemum seedlings are placed in the center of the pot, and the seedlings are righted and compacted with soil to keep the soil. When the seedlings grow up, they should be replaced with 23-27 cm pottery pots according to their growth needs. When changing pots, if there is decomposed base fertilizer, it can be used as base fertilizer to pad at the bottom of pots to supplement the nutrition of culture soil, which is beneficial to plant growth.

water

Watering is a routine and meticulous work, and it is also the key to chrysanthemum growth. It is best to irrigate with river water, pond water and stored rainwater with less minerals. The water temperature should be close to the soil temperature, and it should be watered at noon in winter and in the morning or evening in summer. The amount of watering depends on the weather, soil and seedlings: in the high temperature and dry season, the evaporation is large, and it is watered 1-2 times a day; Water less or no water in cold rainy days. In case of heavy rain, it should be watered in time to avoid waterlogging, rot and death of chrysanthemum roots. See the seedlings and master the water demand law of chrysanthemum in different growth stages. Newly transplanted and potted chrysanthemum seedlings must be watered enough for the first time, and the amount of water at seedling stage should not be too much. With the growth of chrysanthemum seedlings, the temperature will gradually increase and the water quantity will also increase. The evaporation is small after removing the core and shaping, so it is necessary to reduce the watering amount and return to normal after germination. After the growth period, when the buds are ready to release, the water demand is more, and the water demand will decrease after flowering. It seems that before watering, check whether the topsoil is white, and then water it when the soil is white. Avoid continuous watering of wet basin soil. If the pot soil is too wet for a long time, it will cause chrysanthemum seedlings to wither or die. If soil splashes on the leaves after watering or raining, it should be washed with clear water in time, otherwise the leaves will fall easily.

Step 3 apply fertilizer

The amount and time of fertilization depend on the growth of chrysanthemum seedlings. If the leaves are thin and yellow, it means that the fertilizer is insufficient; Thick black leaves indicate excessive fertilization. The growth period of chrysanthemum is mainly based on nitrogen application, and the principle of thin chemical fertilizer application is adhered to. Fertilization at seedling stage is light and the dosage is small. Generally, once every 10- 1 5 days 1 5% decomposed human excrement is applied. In the middle growth period, the demand for fertilizer increases. Fertilize once every 3-4 days, but consider the differences between varieties and individuals, such as applying more coarse seeds instead of fine seeds, applying less dark green leaves and applying more yellow-green leaves. During the budding period of chrysanthemum (half a month before the bud begins to germinate), the use of nitrogen fertilizer must be stopped, and exogenous fertilization should be carried out with 1% potassium dihydrogen phosphate once a week, ***3 times. After the bud is formed, continue to use concentrated nitrogen fertilizer (20%-30% decomposed human feces) until it blooms. When applying fertilizer, it is necessary to prevent the fertilizer from splashing on the leaves, and the residual fertilizer on the leaves should be washed with clear water immediately. Be sure to water the next day after fertilization (commonly known as "backwater").

4, removing core and bud

Removing the top of the main branch can promote the flowering of new branches, control the height of plants and prolong the flowering period. For example, after the last topping, Xiao Ju can blossom after 70 days, and chrysanthemum can blossom after 80 days. Generally, the number of enucleation of chrysanthemum is 3 times, and that of Xiao Ju is 5 times. Half a month after chrysanthemum transplanting (the end of mid-June), the plant height is about 20 cm, and the first coring can be carried out. The method is as follows: leave 3-4 leaves at the base (3-4 buds can germinate) and pick all the main leaves at the top. About 25 days later, the axillary buds of the leaves grow side branches again. At this time, leave two leaves under the lateral branches, pick all the others, and then stop for 25 days (usually 4 days before beginning of autumn or 3 days after autumn begins at the latest). The method is as above. Xiao Ju's every worry, about 18 days apart, stopped in late August. After the chrysanthemum stopped, new techniques and new buds sprouted, and these new buds should be pulled out at any time. After half a month (late August), cut off the new branches and redundant branches, leaving only 5-7 evenly distributed technical strips as needed. Chrysanthemum buds are many. In order to achieve the predetermined number of flowers and flower uniformity, from the beginning of 10 to the middle of 10, 10, only one bud with the same size as the whole plant is left on each branch, and other buds are picked again, but not all at once, otherwise the damage can't be made up.

5, column

Chrysanthemums tend to lodging easily when they grow up, so a pillar should be set up next to the trunk of chrysanthemums in late July. The number of columns can be increased or decreased according to the number of flower heads, and the column material is made of thin bamboo poles. When flowering, tie each flower at different distances and angles to make it evenly distributed, neat and beautiful.

Question 3: How to raise chrysanthemums? 1. timely control pot fertilization. Chrysanthemums are like fertilizer. If fertilization is improper, it will easily lead to excessive growth, excessive fertilization and thinning of plant height and leaves. Therefore, phosphorus and potassium fertilizer should be the main base fertilizer. Topdressing should not be too early. If the leaves are small and thin and yellow, spray 0. 1% urea solution several times until they turn green. If there are symptoms such as phosphorus deficiency and potassium deficiency, 0.2% potassium dihydrogen phosphate solution should be sprayed (available in flower market). From the end of autumn to the beginning of flowering, fertilizer and water should be sufficient, and its concentration should be gradually increased, and attention should be paid to increasing the application of phosphorus and potassium fertilizer, which can make the flower color positive and the flowering period long.

Second, potted chrysanthemums should be watered in a timely and appropriate amount. Even in the vigorous growth period, the daily watering amount only needs to be kept at noon during the day, that is, foliar water is sprayed once every morning and evening.

Third, chrysanthemum generally needs to change pots 2-3 times during the whole growth process. Transplanting in a small pot with a diameter of about 12cm at seedling stage, in a pot with a diameter of about 15cm at seedling stage and in a pot with a diameter of about 20 cm before bud differentiation. At this time, fertilizer should be added in time. Only in this way, the flowerpot will gradually increase, and the soil in the pot will gradually increase, which is conducive to supplying the right amount of water and fertilizer needed for each growth and development stage. Don't raise seedlings in big pots or small pots. If excessive branches and leaves are found, some soil or fibrous roots can be removed.

Fourthly, timely coring can promote the development of lateral branches and effectively reduce plant height. The time and frequency of pit removal of potted plants vary with the art of shape selection. Generally, 4-7 flowers are left, and 4-5 leaves are left for coring after chrysanthemum seedlings are planted. When 4-5 leaves grow on its side branches, 2-3 leaves are left on each side branch for the second coring.

Five, spread buds and sparse buds Chrysanthemum seedlings, many axillary buds germinate, you need to pinch them off with your fingers in time, otherwise it will consume a lot of nutrients and send out many tiny side branches, making the plants look chaotic. During bud pregnancy, lateral buds sometimes appear on the branchlets under the terminal buds. Except what needs to be preserved, the lateral buds should be removed as soon as possible to promote the hypertrophy of the terminal buds.

Sixth, lift the leaves. As the saying goes, "flowers need green leaves." Proper cutting, rational fertilization and watering during the growth of potted chrysanthemum can prevent dead leaves from falling off, ensure green leaves and improve ornamental effect.

Question 4: How to raise chrysanthemums? Just water it regularly, sometimes fertilize it.

Question 5: Can a man named Qiuhua live for many years? How to maintain it when it is planted in the ground? In winter in the north, you can keep warm by covering straw or livestock manure to help a person named Qiuhua spend the winter!

Question 6: Can I keep it in the home of a man named Qiuhua? It is harmful to raise chrysanthemums indoors.

Because: at night, the photosynthesis of plants stops, leaving only breathing, which will increase the indoor carbon dioxide concentration. Photosynthesis and respiration coexist in plants, each exercising its biological function and mission, and cooperating with each other. Obviously photosynthesis releases oxygen and absorbs carbon dioxide; Breathing releases carbon dioxide and absorbs oxygen. The intensity of photosynthesis determines the amount of oxygen released by plants, but it does not mean that photosynthesis can determine respiration, and there is no absolute dependence between them. The main controlling factor of photosynthesis is light, while the main controlling factor of respiration is temperature. The respiration of plants has always existed, including day and night; Photosynthesis mainly occurs during the day. This also determines that most plants release carbon dioxide and absorb oxygen day and night; However, in the case of light, photosynthesis far exceeds respiration, which makes the carbon dioxide released by respiration almost directly used by photosynthesis, which shows that plants release oxygen and absorb carbon dioxide during the day. But photosynthesis almost stops at night, so carbon dioxide is mainly released at night, so putting it in the bedroom at night will increase the concentration of carbon dioxide, which is very harmful to the body.

However, cactus is different. For succulent plants such as cactus, the cells of these plants adopt the "acid metabolism pathway (CAM) of Sedum". Therefore, unlike other plants, the stomata of these plants are closed during the day, and no or little gas exchange occurs. At night, however, it is different. They exchange gases through photosynthesis and respiration, and obviously release far more oxygen than carbon dioxide, which is completely different from other plants. However, this does not mean that photosynthesis of succulents occurs at night. In fact, these carbon dioxide are stored in organic acids (such as malic acid) in mesophyll cells, and when there is light, these organic acids decompose in vascular bundle sheath cells to release carbon dioxide for photosynthesis. Therefore, putting such plants in the bedroom at night will increase the concentration of oxygen, which is beneficial to health.

Placing some anti-pollution flowers indoors can purify the air. For example, ivy can "eat" benzene, chlorophytum can "swallow" indoor carbon monoxide and formaldehyde, and bracts of Araceae can absorb benzene and trichloroethylene. 10 square meter room, if there is an anti-pollution plant, it will be of great benefit to air purification.

In modern houses built with reinforced concrete prefabricated panels, the air humidity is far below the normal standard, and a plant named Cyperus likes water, so potted Cyperus should be placed in a deep pool to turn a "desert" into an "oasis". Feeling depressed, the reason is not lack of oxygen indoors, but lack of negative oxygen ions. When there is a TV or computer in the room, negative oxygen ions will decrease rapidly. There are many plants that can be planted indoors that can produce negative oxygen ions ―― these plants are cypress, arborvitae and cedar.

If the room area is small, you might as well plant some lower plants, such as cactus. At present, spruce and other low conifers are popular in the west, which can make the room full of refreshing tree fragrance. Many flowers and plants suitable for indoor planting have sterilization function. If some potted oranges, rosemary, mahogany and chlorophytum are placed indoors, the bacteria and microorganisms in the air will be greatly reduced.

Some of the flowers mentioned above are easy to grow, which can be seen in the flower market generally, and the price is relatively low, which is very suitable for family planting.

Plants that can absorb toxic substances, such as aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum, are natural scavengers, which can remove harmful substances in the air. Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe vera is also a good absorbent of formaldehyde.

In addition, plants with air purification function also include:

Kidney fern, cyrtomium fortunei, Chinese rose, crape myrtle, clove, magnolia, osmanthus fragrans, clover, aloe, Commelina communis, auricularia fern, cactus, tiger orchid, agave, pineapple, cactus, arrow lotus, epiphyllum, gem flower, Sedum, Sedum purpurea, ivy, cycad and chrysanthemum.

? Radiation-resistant ornamental plants

Some ornamental plants have the function of absorbing electromagnetic radiation. Placing these plants at home or office can effectively reduce the electromagnetic radiation pollution caused by various electrical and electronic products. These plants include: cactus, gem flower, Sedum and other succulents.

Question 7: How to raise chrysanthemum with many varieties and long flowering period, which is a good ornamental flower. If it can be opened in the Spring Festival, it will undoubtedly increase the festive atmosphere of the festival. The ways to make chrysanthemums open in the Spring Festival are as follows:

Chrysanthemum needs more than 65,438+000 days from planting to flowering, and cutting propagation should be carried out in the middle and late August of the lunar calendar. The method is to cut 5-7 cm long tops or branches from robust mother plants as cuttings, cut off basal leaves, dip the cuttings in mud, then insert them into basin sand, water them, shade them properly, keep the basin sand moist, and insert them after 65,438+00-20.

Make good use of fertilizer and water chrysanthemum is a short-day plant that likes sunshine, humidity, cold, cold and waterlogging. The basal fertilizer of the soil in the basin should be mainly phosphorus and potassium fertilizer to control the stems of Miao Zhuang, and nitrogen fertilizer which can promote the growth of branches and leaves should not be applied in a partial way. In order to make chrysanthemum grow short and strong, with dense leaves and not empty feet, it is not advisable to water it too much after transplanting, but it is necessary to loosen the soil frequently to weed, keep the soil loose and promote the development of roots. Generally, water is poured once in the morning on a sunny day, and the amount of water can be guaranteed to evaporate at noon. Apply decomposed dilute liquid fertilizer once every 1-2 weeks, or spray 0.3-0.4% urea or potassium dihydrogen phosphate on the leaves to promote seedling health. With the growth of plants, the concentration of liquid fertilizer can be gradually increased until buds appear.

In order to increase the number of flower branches and promote more flowering, it is generally necessary to pick the heart three times. After the survival of colonization, the main stem leaves two cuttings for the first time every 13 days, and then two cuttings for each side branch. The third topping is about 68 days before the Spring Festival, neither too early nor too late, so as not to miss the Spring Festival flowering. In order to reduce nutrient consumption, all axillary buds should be erased when the plants just sprout.

Aphid is the main pest of chrysanthemum, which has a great influence on flowering, and even leads to the withering of branches and leaves or even the death of the whole plant. Control method: spray 40% dimethoate 1000- 1500 times or 400-600 times washing powder solution (add a little urea).

Question 8: How to raise potted chrysanthemums (simple and practical version) How to plant chrysanthemums 1. Changing pot soil is an important stage in the whole growth process of chrysanthemum, which usually needs to be changed 2-3 times. Transplanting in a small pot with a diameter of about 12cm at seedling stage, in a pot with a diameter of about 15cm at seedling stage and in a pot with a diameter of about 20 cm before bud differentiation. At this time, fertilizer should be added in time. Only in this way, the number of flowerpots will gradually increase, and the soil in the pots will gradually increase, which will be conducive to supplying the right amount of water and fertilizer needed in each growth and development stage, spraying new high-fat films, and shortening the rate of slow seedling.

Second, chrysanthemums like fertilizers, and improper fertilization can easily lead to excessive growth. Therefore, phosphorus and potassium fertilizer should be the main base fertilizer. Topdressing should not be too early. If the leaves are small and thin and yellow, spray 0. 1% urea solution several times until they turn green. From late autumn to early flowering, there should be sufficient fertilizer and water, and its concentration should be gradually increased, and attention should be paid to increasing the application of phosphorus and potassium fertilizer, which can make the color of flowers positive and the flowering period long, and spray a new high-fat film in time, greatly improving the rate of restricted components of pesticides.

Thirdly, proper water control is the only effective measure to make chrysanthemums grow short, dense, fat and barefoot. Potted chrysanthemums should be watered in a timely and appropriate amount. Even in the vigorous growth period, the daily watering amount only needs to be kept until it evaporates at noon during the day. Spray foliar water once every morning and evening in hot weather, and spray a new layer of high-fat film to adjust the water absorption.

Fourth, during the budding stage, lateral buds sometimes appear on the branchlets under the terminal buds. Except for those who need to be preserved, the lateral buds should be removed as soon as possible to promote the hypertrophy of the terminal buds, and the timely spraying of Zhuangdiling can promote the robust buds, plump petals, bright colors, rich flowers and prolonged flowering period. As the saying goes, "flowers need green leaves." During the growth of potted chrysanthemum, reasonable fertilization, watering and pest control can not only prevent the dead leaves from falling off, but also ensure the green leaves and improve the ornamental effect.

5. Spraying Wang Cuihua No.3 in time can transform the vegetative growth of plants into reproductive nutrition, inhibit the overgrowth of main shoots, promote the differentiation of flower buds, blossom more, and timely topping can also effectively depress the plant height. The time and frequency of pit removal of potted plants vary according to different plastic arts. Generally, 4-7 flowers are left, and 4-5 leaves are left for coring after chrysanthemum seedlings are planted. When 4-5 leaves grow on the side branches, 2-3 leaves are left on each side branch for the second coring.

Question 9: How to raise chrysanthemums in winter Because of the large temperature difference between north and south in China, the management methods of chrysanthemums are different. Chrysanthemum cultivated in the open air in the south should be cut off at the height of 15 cm from the ground when the flowering plants wither, and covered with fallen leaves and soil after watering, so that the stems can be Gan Lu for a while, while in the north, chrysanthemum must be moved indoors for the winter.

The methods of successfully wintering chrysanthemum indoors are as follows:

1. After the potted chrysanthemums wither, cut off the withered stems and water them thoroughly. Then move it to a sunny room, the temperature should not be too hot, as long as it is above zero. The main thing is to control the watering well until the soil in the basin is dry, and don't water it too much at a time. When the weather gets warmer, slowly increase the amount of water and then move outdoors. After the plants germinate new buds, they can be cut into branches, which can make chrysanthemums grow better.

2. In late autumn and winter, the first generation of new buds sprouting from the roots of chrysanthemum plants are selected for cutting. Roots with buds can be dug out of the soil and then inserted into the prepared flowerpot. Then move indoors, the indoor temperature should not be too high, keep it above zero, water less, and keep the pot soil slightly wet. Stay until March and April of the following year, and then move to a sunny place outdoors.
