Growth habits of purple jasmine

Before studying how to raise purple jasmine, we need to know its growth habits. Purple jasmine is a kind of plant that likes warm and humid environment, its cold tolerance is weak, if the winter temperature is low, the aboveground part may die; like semi-shady environment, not resistant to high temperature, like fertile soil, general requirements for fertilizer and water.

How to raise purple jasmine

1. Lighting

Purple jasmine needs enough light to grow, but the best light condition is a little shaded place, afraid of strong light, too strong light will cause leaves to fall off, and flowers will close in strong light, which will affect their appearance.

2. Temperature

Purple jasmine is weak in cold resistance. If the temperature is not controlled in winter, its aboveground part is easy to frostbite. In the south, its underground part can survive the winter safely and become perennial grass flowers, and new plants will sprout in the following spring.

3. Soil

The requirement of purple jasmine for soil is fertile, loose and good drainage, in which good drainage is very key, it can make the root absorb nutrients more efficiently when watering and fertilizing, and we should also pay attention to the health and safety of the soil.

First, when conserving African chrysanthemum, we should pay attention to the diseases that may occur on it.

1. Epidemic disease: the key technology for prevention and control is that the continuous cropping soil must be disinfected with Weibo mu and formaldehyde, the usage and dosage can be described in the instructions; shallow planting, the root neck exposed on the surface 1cm; to prevent the soil from getting too wet, the soil below 10cm can be watered. At the initial stage of the disease, some leaves became red and began to wilt, and the roots were irrigated with 58% ethyl phosphorus, aluminum, manganese and zinc 400 times, and then irrigated with 64% poisonous alum powder 500 times in the next 7 days. the application time was carried out when the temperature was low in the morning and evening, and stopped when the temperature was higher than 28 degrees Celsius. Once every 7 days, three times in a row.

2. Powdery mildew: the key technology for prevention and control is to keep the ventilation in the shed low and humid; to remove the diseased leaves in time; to spray 1500 times of methyl topiramate at the time of onset, or to control it with 20% carbendazim smoke, once every 7 days, even for 2-3 times. In addition, sulfur fumigation was used to control the disease. 20-30g sulphur powder was put into each fumigator each time. After the curtain was released at 17:00 every day, the shed was kept airtight, heated by electricity for 2 hours, and the sulfur powder was changed every 6 days for 15 consecutive days. During the onset period of powdery mildew, powdery mildew can be eliminated by fumigation for 8-10 hours every day for about 10 days.

3. Spot disease: the key technology for prevention and control is to remove the diseased leaves in time and destroy them; at the initial stage of the disease, spray 2.5% nitrilazole EC 300 times or 70% methyl thiophanate wettable powder 800 times, spray once every 7 days, and spray 2-3 times continuously.

4. Botrytis cinerea: the key technology of control is to control humidity is the key to control Botrytis cinerea. Remove the densely planted and overgrown leaves; increase ventilation and keep the air humidity at 75 per cent; water from below the canopy; in order to prevent water vapor from condensing on the flowers, open the side shed gradually after 10:00 in the morning to avoid a sharp rise in temperature in the shed; foliar spray of 1500 times of methyl topiramate was used in the early stage of the disease, and combined with aerosol for prevention and treatment.

5. Whitefly: the key technology of control is to thoroughly remove weeds; insert the yellow board for monitoring at any time, once pests are found, timely measures should be taken; good pesticide selection and correct use: whitefly is easy to produce resistance to pesticides and must be rotated. The effective pesticides are cypermethrin, avermectin, imidacloprid and so on. The spraying time was chosen at dawn, sealed the greenhouse for 4-5 hours after spraying, and sprayed continuously the next morning.

Second, 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.

Third, lighting 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.

Fourth, 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.

Fifth, 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.
