The adoption of shade net covering technology can promote the growth of green peppers, increase the yield and quality, and make up for the off-season market of summer and autumn vegetables. First, choose the varieties of heat-resistant, disease-resistant, long-term growth of the late-maturing varieties, such as Zhongjiao No. 4, Luo Dian KDT1, pepper No. 2 and so on. Second, the cultivation of strong seedlings 1. Soak germination. Seeds were soaked in warm water at 55°C for 15 to 20 minutes and then soaked in warm water at 20°C for 8 to 12 hours. After the seeds are soaked and drained, they are drained and wrapped with a damp cloth. The germination is carried out in an environment of 25 to 30°C. The seeds are washed once a day with fresh water, and 80% of the seeds are sown when exposed. 2. Sow. Usually sowed in May, using flat seedlings. 3. Seedling management. During the nursery period, the temperature during the day is maintained at 20 to 25°C and 12 to 15°C at night. After the cotyledons were unfolded, the young plants were sprayed with water and then sprinkled with water once in order to prevent dead seedlings. Seedlings of 2 to 3 true leaves were planted individually and the seedlings were 10 to 12 cm apart. Sub-seedling with soil from the seedlings, Mingshui seedlings. When 8 to 9 leaves are true, water-controlling seedlings can be planted in 4 to 5 days. Third, colonization 1. Preparation. Before the planting, clean the garden first, cover the silver-gray shade net in the plastic greenhouse or greenhouse scaffold, and leave 50 cm of vents on the side. For every 1/15 hectare (1 mu) in the shed, 5,000 to 6,000 kg of high-quality organic fertilizer is fully applied and 20 to 25 kg of compound fertilizer is used. Deep-turning, leveling, and boring are performed to make the flat 120 cm wide. 2. Method. Colonize on a sunny evening or cloudy day. The seedbeds were irrigated with water and transplanted with soil. Each row was planted with 2 rows. The distance between the points was 40-45 cm, 2 per hole, and 1/15 hectares were planted with 2600-3000 holes. Immediately after planting watering to promote slow seedlings. Fourth, field management 1. Fertilizer management. After 3 to 5 days after planting, plunge the seedlings for 1 time and then control the seedlings until they are seated. After the peppers sat, they poured water and applied urea with water, which was 20 kg per 1/15 hectare. After 3 to 5 days, they were poured with water once more. After the “four-mother bucket†is seated, it is necessary to keep the soil moist and top dressing once after each harvest. It is better to use urea and compound fertilizer alternately. The amount per 1/15 ha is 7.5 to 10 kg. 2. Temperature management. After easing the seedlings, the temperature in the shed was lowered to 25° C. in the afternoon and the shade net was opened. In the morning, the temperature rose to 30° C. and the shade net was covered. The day and night temperatures must be covered throughout the day when they exceed 25°C. When the sky is overcast, the shade net on the shed must be opened, and when it rains, it is necessary to cover the shade net in time to prevent the danger of heavy rain. When the temperature falls below 30°C during the day, remove the shade net to facilitate the robust growth of the plants. In mid-October, when the temperature drops to 15°C on the night, the shed can be covered with films for delayed cultivation. V. Prevention and control of pests and diseases Virus disease can be sprayed with 20% virus A WP 500 times at the beginning of the disease; Prevention of anthrax can be sprayed with 50% anthraquinone Fumei 500x in the early stage of disease; 90% B can be used to prevent and control diseases. Aluminum phosphate 800 times. The control of aphids can be controlled with 2.5% bifenthrin emulsifiable concentrate 3000 times spray; the control of tobacco budworm and cotton bollworm can be sprayed with BT emulsion 250 times solution at the hatching hatching stage of adults and the young larvae.
