I. Agricultural control
(1) Control the temperature and humidity in the shed. Using the traditional ground irrigation method, a thermometer is attached to both ends of the shed, and the temperature and humidity in the shed are periodically measured to determine the temperature drop and the temperature of the curtain. During the daytime, the temperature in the booth is controlled between 23°C and 27°C, and the nighttime temperature is controlled between 16°C and 20°C. The relative air humidity is controlled between 70% and 80%. When the outside temperature is greater than 15°C, ventilation is gradually performed day and night, and the bottom wind is placed in the front of the shed, from small to large. After every two meters, a tuyere is opened, and the bricks are laid horizontally to form an A-shaped mouth. When the outside temperature rises to 16°C on average, the bricks are placed horizontally (10 cm in height). When the temperature is 19°C to 21°C, the bricks are placed vertically (20 cm. high). As the temperature in the shed rises, the waist and top winds are released, or the shade net is covered. Exhaustion must be smooth.
(b) Manual disinfection. In the buffer room and in front of the entrance to the greenhouse, 1.2m long and 1m wide grass mat lime disinfectant pools are constructed. Lime is sprinkled every 15 days to keep the pools moist. Into the greenhouses, the feet are disinfected through the pool to prevent external bacteria sources from being carried. Use latex gloves to pick the fruit and cut it with scissors soaked in disinfectant. Equipped with a 0.5% potassium permanganate disinfectant barrel, such as picking the diseased fruit and immediately using its disinfecting scissors and latex gloves, to prevent spread of pathogenic bacteria.
(3) Increase phosphorus and potassium fertilizers. 0.3% potassium dihydrogen phosphate solution was used to micro-spray the stems and leaves, 30 kg of fertilizer solution per acre, once every 7 days to improve the disease resistance of the plants.
(D) covered grass wet. Spread 3 to 5 cm thick wheat straw or wheat bran between large rows of green peppers to absorb moisture and dampen the humidity in the shed and reduce the breeding and development of diseases.
Second, pesticide control
(1) Epidemic prevention and control. After the green pepper colonizes and survives, it is sprayed alternately with 64% antivirus 400 times, 72% metalaxyl manganese zinc 500 times, and 72% Duponcco 700 times, sprayed every 7 days, and even sprayed 2 Up to 3 times.
(B) Gray mold and Sclerotinia prevention and treatment. Peppers are sprayed with peppers that are sprayed with 20% of Green Emperor 400 times liquid or fast-gelling 1200 times to control gray mold during the period of pepper spraying; spraying 40% wowing 400 times liquid or applying Baikang 1500 times to control Sclerotinia.
(c) Prevention and control of soft rot. In the early flowering period and the post-harvest period, the condition monitoring should be strengthened. 77% of the 700 times can be used to kill and 72% of the agricultural streptomycin 3000 times can be sprayed alternately.
(d) Prevention and control of anthrax. At the end of the result period, 75% of chlorothalonil 400 times or 70% thiophanate-methyl 800 times was used for spraying. The disease was sprayed with a 300-times new 300,000 times solution to prevent the plant from dropping. It is appropriate.
(e) Prevention and treatment of cotton rot. Sunny days can be sprayed with 64% of the antivirus 400 times, and when it is cloudy or rainy (greater than 85%), it is fumigated with 20% of the soymilk fasting agent, 250 to 300 grams per acre, and closed in the evening. Room, igniting the drug, opened the air outlet after the sunrise the next day to release the air exhaust, before entering the shed operation.
