What are the requirements for the culture of gerbera?

The culture method of African chrysanthemum-African chrysanthemum requires temperature, irrigation, topdressing, see below for details. If you can pay attention to the place above, it is not difficult to cultivate a beautiful African chrysanthemum.

First, temperature requirements. The cultivation facilities should be used to meet the temperature requirements of African chrysanthemum at seedling stage, growth stage and flowering stage, so as to facilitate normal growth and flowering. Outside South China, there is no open field for overwintering, so it needs to be cultivated in greenhouse, and can be cultivated in greenhouse outside the Yangtze River basin. In summer, the roof should be covered with a shade net and the plastic film on both sides of the greenhouse should be opened to cool down. When the external night temperature is close to 0C in winter, the plastic film must be covered in the shed. In case of sunny and warm weather, the southern end of the greenhouse was opened for about an hour of film ventilation at noon.

Second, temperature requirements. African chrysanthemum is a light-loving flower, which needs full light in winter, but it should pay attention to proper shading and strengthen ventilation in summer to reduce the temperature and prevent high temperature from causing dormancy.

Third, irrigation requirements. After planting, the seedlings should be properly moist and squatted, so as to promote the development of root system and form seedlings quickly. During the period of exuberant growth, adequate water supply should be maintained, irrigated every 3-4 days in summer and about half a month in winter. Flowering irrigation should be careful not to make the center of the leaves stained with water to prevent the flower buds from rotting. In open field cultivation, attention should be paid to waterlogging prevention. In addition, irrigation can be combined with fertilization.

Fourth, the requirement of topdressing. African chrysanthemum is a perennial flower that likes fertilizer, which has a great demand for fertilizer. the proportion of nitrogen, phosphorus and potassium is 15:18:25. Special attention should be paid to the supplement of potash when topdressing. Generally, each mu sells 2.5 kilograms of potassium acid, 1.2 kilograms of ammonium nitrate or ammonium phosphate, every 5-6 days in spring and autumn, and every 10 days in winter and summer. If the plant is semi-dormant caused by high temperature or low temperature, fertilization will be stopped.

Fifth, the management of soil, fertilizer and water in gerbera culture. African chrysanthemum does not have strict requirements on soil and likes slightly acidic soil with a pH value of 6.0 to 6.5, which can also grow and blossom in neutral or slightly alkaline soil, but its leaves are prone to chlorosis in alkaline soil, so it is suitable for sandy loam with loose air and rich humus. Generally, materials with good permeability such as pine needles, rice husks and vinegar bran are mixed with mature organic fertilizers (such as pig manure, cow manure, etc.) and sandy soil, with a volume ratio of about 1 ∶ 1 ∶ 1, mix well with broad-spectrum fungicides such as carbendazim, mancozeb, etc., and cover the film for 3 to 5 days. In addition to the great demand for nitrogen, phosphorus and potassium, potted African chrysanthemum also has a great demand for magnesium. Therefore, 0.2%-0.4% physiological acid fertilizer, mainly ammonium nitrate, calcium superphosphate, potassium sulfate and magnesium sulfate, should be sprayed on the leaves every 2 to 3 weeks in the growing season. It can also be combined with watering to irrigate thin alum fertilizer water. The interval between autumn and winter can be longer, reduce the concentration, and appropriately increase the application of phosphate fertilizer. Enhance the cold resistance of the plant. Potted African chrysanthemum is more resistant to drought, afraid of stagnant water, which is easy to rot roots. When watering and fertilizing, be careful not to put water in the center of the leaves, otherwise it is easy to make the flower buds rot. The water temperature should be slightly higher than the soil temperature, otherwise it will be infected with bacterial blight.

What is the culture method of African chrysanthemum? what are the matters needing attention in the culture of African chrysanthemum?

Basic information of African chrysanthemum: African chrysanthemum, Compositae, alias Fulang flower, sunflower, gorilla chrysanthemum, sunflower, etc., are perennial herbs, terminal inflorescences, flowers are red, white, yellow, orange, purple and so on. The method of sowing or planting is used for reproduction, and the country of origin is South Africa.

Because African chrysanthemum is native to South Africa, it likes the environment where it is warm in winter and cool in summer, ventilated and sunny. It is not cold-resistant and avoids heat. African chrysanthemum is a light-loving flower, which needs full light in winter, but it should pay attention to proper shading and ventilation in summer. The suitable temperature for growth is 20C--25C in daytime, about 16C at night, and the suitable temperature for flowering is not lower than 15C. The sandy loam with loose fertility, good drainage and rich humus, avoid heavy clayey soil, is suitable for slightly acidic soil, and the optimum pH for growth is 6.0-9.0.

What is the culture method of African chrysanthemum: because of its bright color and low price, African chrysanthemum has become the first choice for families to bottle fresh cut flowers. African chrysanthemum requires loose, fertile, well-drained, humic, deep and slightly acidic sandy loam. In summer, we should pay attention to proper shading and strengthen ventilation to reduce the temperature, prevent high temperature from causing dormancy, be insensitive to photoperiod, and the length of natural sunshine has no effect on the number and quality of flowers. The culture method of African chrysanthemum 1. Soil: African chrysanthemum likes to be rich in humus, good drainage and pH value in 6-6. 5 sandy loam. Potted plants can use slightly acidic soil, soil cultivation should pay attention to the use of fertile soil with good drainage. It can be made from 3 parts of garden soil, 3 parts of peat soil, 3 parts of rotten leaf soil, 2 parts of sand or 4 parts of peat soil, 3 parts of rotten leaf soil, 2 parts of sand and 1 part of perlite. Culture method of African chrysanthemum 2. Temperature: the optimum temperature for growth is 20-25 degrees, the optimum temperature for germination is 18-20 ℃, the suitable temperature for winter dormancy is 12-15 ℃, and the growth stops when it is below 7 ℃. The cultivation method of African chrysanthemum 3, light: potted or planted on the ground should be placed in a place with sufficient light in order to grow robust and brightly colored. If the light is insufficient, the development is stunted and the flowers are small and light. The cultivation method of African chrysanthemum 4. Watering: African chrysanthemum likes wet soil, afraid of wet water and drought. During the growing period from March to June and September to October, it is necessary to water more, but not stagnant water, and it is suitable to be moist; when the winter temperature is lower than 12 "C, it is better to water less than 1000. The cultivation method of African chrysanthemum 5. Fertilizer: African chrysanthemum likes fertilizer very much. when the fertilizer is sufficient, it grows and blossoms vigorously. Therefore, it is necessary to apply sufficient base fertilizer before planting, and once every half a month from June to October after planting. Breeding methods of African chrysanthemum 6. Insect pests: the diseases of African chrysanthemum include leaf spot, powdery mildew and virus. Leaf spot disease was sprayed with 70% methyl topiramate wettable powder 800 times or 50% carbendazim wettable powder 500 times. Powdery mildew was prevented and treated with 1500 times of methyl topiramate or 1000-1200 times of 1000-1200 times of thiophanate, once every 7-10 days, two to three times in a row.

Culture method of African chrysanthemum 7. Pruning: the lower leaves of the gerbera basal leaf cluster are easy to wither, yellow and senile, which should be removed in time, which is not only conducive to the sprouting of new leaves and flower buds, but also conducive to ventilation and enhance plant growth. In addition, if the branches and leaves of the plant are too luxuriant to cover each other, some of the leaves can be removed properly.

Matters needing attention in the cultivation of African chrysanthemum: 1. Do not let the fertilizer spread to the heart of the chrysanthemum when fertilizing, otherwise the growing point of the heart is easy to rot and die, and the fertilizer can not be splashed on the leaves, otherwise the leaves will be burned out. 2. Gerbera gerbera is sensitive to temperature and light intensity. In summer, it is necessary to keep the soil moist and free from drought, cover the shading net with 50% light transmittance, and spray to the leaves to increase air humidity and lower temperature. Matters needing attention in the cultivation of African chrysanthemum 3. In winter, the work of keeping warm should be fully done, and the temperature should not be less than 10 ℃ at night and not less than 15 ℃ during the day, which are very beneficial to improve the freshness of gerbera.
