Chaotianjiao carries out three aspects of seedbed management, that is, early heat preservation and antifreeze, promote early emergence and emergence of seedlings; moderately adjust temperature and humidity in the medium term to prevent burning seedlings and seedlings; strengthen seedlings in the later stage, prevent growth, and improve seedling adaptation Sex and stress resistance.
1. The seedlings should be selected from the wind and the soil at noon, and the plastic film should be covered at any time. When 4~6 leaves are ventilated, pay attention to the temperature rise at noon in the raft. The vents are gradually increased from small to prevent the sudden change of temperature and cause flash seedlings. 5~7 days before planting, take the film all day to perform adaptive exercise.
2, water and fertilizer management seedbeds generally do not water, but the topsoil is dry, the midday seedlings wilting can spray a little warm water at noon. When the bottom fertilizer is low, the seedlings can be sprayed with 0.4% urea water. Third, cultivation techniques
1. Apply enough base fertilizer, finely tidying the earth and welcoming the peppers in the sky. It is not suitable for continuous cropping. Applying the base fertilizer and re-applying phosphorus and potassium fertilizer, 3000-5000 kg of high-quality soil manure, 25 kg of diammonium, 15-20 kg of potassium sulfate, 10-15 kg of urea, or 50 kg of superphosphate, 50 kg of potassium sulfate per acre. 25 kg, urea 20~30 kg or ammonium bicarbonate 40~50 kg.
2. When cultivating the mulch and mulching the soil, it is necessary to deep-plow the fine hoe, to achieve smooth and fine smashing, and to plow 25 cm or so, and then ridge the film, the ridge height is 10~15 cm. When the film is covered, the film should be tensioned and tightly sealed with earth pressure. It should be completed 7 to 10 days before transplanting, and it may be appropriate in advance according to the public opinion.
3, strong seedling transplanting, reasonable close planting 1 transplanting time. Spring sowing is generally required to be completed by May 1st. Areas with long frost-free period can be properly advanced, and transplanting should be completed within 5 days after the final frost period. 2 large seedlings and strong seedlings transplanted. The seedlings and seedlings are transplanted slowly and have strong resistance to stress, which is conducive to high yield. 3 transplanting method. On the day before transplanting, the seedbed should be watered so that the seedlings are more soiled and less damaged. When carrying the seedlings, gently handle them to reduce the damage of the seedlings. Each row was planted 2 rows, and the planting holes were dug according to the plant spacing, and 2 plants were planted in each hole. The soil around the seedlings was pressed tightly, and then watered immediately after planting. Poor watering conditions can pour water into the hole and then plant the seedlings. 4 reasonable close planting. Chaotian pepper is small in size, compact in plant, and suitable for planting in the field. The average row spacing is 40~45 cm, the hole spacing is 20~25 cm, and each hole is double planted, and the planting is 6500~7000 points. Fourth, strengthen field management
1. Fertilizer management generally adopts a one-time fertilization method. During the growth period, it is generally not fattening. For the field with poor fertilizer retention or de-fertilization, the flowering period combined with cultivating and applying 20 kg of urea. Watering should be carried out in a timely manner according to the dry and wet conditions of the surface. Watering should be carried out on cloudy days or in the evening. Do not simmer in the hot sun. Do not flood the water.
2. After cultivating and weeding, the seedlings should be cultivated in time to increase the ground temperature and promote early seedling growth.
3. The yield of topping the pepper is mainly concentrated on the side branches, accounting for 80%~90%, and about 10% on the main stem. The topping delay affects the growth of the lateral branches, so within 5-7 days after the slow seedling, the tops of the 8 leaves are finished, thereby limiting the growth of the main stem, promoting the lateral branches, and increasing the yield.
4, pest control Chaotian pepper disease mainly include anthrax, viral disease, epidemic disease, bacterial angular spot disease, sunburn and so on. High temperature and drought, aphids are prone to virus disease, combined with sputum spray virus A, plant disease prevention; high temperature and high humidity conditions prone to bacterial angular plaque, bacterial wilt, optional anti-virus cockroach, can be used Killing and controlling; rainy season, especially after heavy rain, the weather turns fine and high temperature is prone to epidemic disease. It is better to use Kebo, anti-virus and other pesticides to control; weather is dry, glare is exposed, prone to sunburn, should spray amino acid calcium, ammonia calcium in time Bao and other agents prevent and enhance resistance. Insect pests mainly include aphids, planthoppers, and cotton bollworms. , enemy killing, deltamethrin and other spray control.
