Pollution-free dry chili production technology

1 Requirements for bases and environmental conditions To produce high-quality, safe dried chilli peppers, we must first choose a good natural environment, no pollution-free enterprises within 5km, and no direct acceptance of industrial “three wastes” and agricultural production areas contaminated by agriculture, urban life, and medical waste. 2 Production Management 2.1 Variety selection The selection of high-quality, disease-resistant, high-yield varieties, such as: Tianyingjiao, Wangdujian pepper and so on. 2.2 sowing sowing time: mid-March to mid-April. The amount used: about 150g per 667 square meters, planting 5000-6000 strains. Seedbed preparation: (1) regardless of seedlings. For each 667 square meters of pepper seedlings, 10 m2 nursery beds are needed, with 4 cm4 cm between the individual plants. (2) seedlings. Every 667 square meters of pepper seedlings need 3 to 5 square meters of seedbed, 1 square meter of per square meter of seedlings with decomposing circle fertilizer, 2 pieces of pastoral soil that has been sieved, mixed and made into nutritious soil, spread on the seedbed. Immersion germination: Sow before sowing 2d, to increase the germination potential, soaking in warm water of 55 °C ~ 60 °C, agitation 15 ~ 20min, remove and soak with 10% sodium phosphate or 0.1% potassium permanganate 20min or 1% Copper sulfate soaking for 5min, washed with water 4 to 5 times, soaked in cold water below 30°C for 8 to 10 hours, washed and dried for 1 hour, then wrapped with clean, oil-free white cloth or towel, put The germination was performed in an environment of 25°C to 30°C. Seeds are spread out as much as possible, and they are turned 1 or 2 times a day. If the seeds are found to be sticky, they should be germinated after washing with warm water at 30°C. When 80% of the seeds are "white". Sowing: Before seeding, the seedbed is soaked with water. After seeping, the bed surface is covered with a layer of fine clay of 0.5 to 1 cm, and then 2/3 of the soil is applied (8 to 10 g of pure carbendazim per square meter of fine soil). After sowing, spread the remaining 1/3 of the drug and then cover the soil with 0.5-0.8cm. 2.3 Seedling management seedlings Two leaves and one seedling time seedlings 1 to 2 times, seedling distance 2 ~ 3cm, between the diseased seedlings, weak seedlings, seedlings, removal of weeds, disease prevention, planting before pouring 1 pervious. Colonization: Select the former for non-solanum vegetables. Soil fertilization: Use 5,000 kg of decomposed fertilizer or compost per 667 square meters, and then apply N10 kg, 12 kg of P2O5, and K2O of 10 kg. During the site preparation, the land is ploughed 20 to 25 cm deep, and the land is to be leveled and finely ground. Do north-south ridge, ridge distance 45 ~ 50cm, ridge height 15cm. Planting period: planting in mid-May. Density of planting: Planting density per plant is 5000-6000, plant spacing is 25-30cm, spacing is 45-50cm. Two-plant colonization of 3500 to 4500 points, the distance between 30 to 40cm, spacing 50cm. In the ditch, half-high ridge spacing staggered by the size of the planting, digging depth 10 ~ 12cm planting points, moderate depth of planting seedlings, watering seedlings immediately after the watering. 2.4 Management after planting (1) Management of post-emergence post-emergence, spraying with 2% potassium dihydrogen phosphate once in combination with cultivator leaves. (2) Flower bud management During the flower bud stage, 1000 kg of human fecal urine is applied per 667 square meters, followed by pure N3 kg. Cultivate one or two times, and carry out earth-cultivation. After entering the rainy season, pay attention to drainage and flood prevention. Even rainy days and storms should be poured with small water in a timely manner. (3) Flower and fruit management and fertilization: Apply 1500kg of human fecal urine per 667m2, and then apply pure nitrogen 7kg, 3kg phosphorus pentoxide and 3kg potassium oxide. Fertilizers should be applied 6 to 10 cm from the roots of the plants. Watering: From July to August, during the high temperature, drought and rainy season, the watering should be controlled by groundwater pouring and light pouring to keep the soil moist. After the rain, the water should be poured in a timely manner. Each 667 square meters after blooming with paclobutrazol 20 ~ 25g Duishui 15kg or 600 ~ 800 times longer than the liquid spray. 3 Pest control 3.1 Hot pepper virus disease (1) Seedlings with 10% imidacloprid wettable powder 1500 times, or 40% dimethoate EC 1000 ~ 2000 times, or 80% dichlorvos EC 1000 times spray to prevent aphids. (2) The initial onset is 20% of the virus A400 times or 1.5% of the Phytopathogenic Emulsion 400 to 500 times, plus 0.3% zinc sulphate spray, sprayed once every 7 days, and generally sprayed 3 times. 3.2 pepper blight 85% epimedium cream 500 times, or 64% antiviral 500 to 600 times liquid, or DuPont Kelu, cream epidemic 500 to 600 times liquid spray, 5 to 7d spray 1, even spray 2 times. 3.3 Anthracnose 75% chlorothalonil 600 times, or 70% thiophanate-methyl spray 800 times, 5 to 7d spray 1 time. 3.4 Bacterial spot (scar disease) 72% agricultural streptomycin 300 ~ 400 times liquid + pepper abundance, or CT (bacterial spirit) 400 ~ 500 times liquid + pepper abundance, or 50% DT500 times liquid + pepper abundance, 7 to 10 days spray 1, even spray 2 to 3 times. 3.5 Helicoverpa armigera When the number of eggs per 100 eggs reaches 20 to 30 capsules, use of Bt emulsion 200 times, 1.8% avermectin 3000 times, or 5% stilbold EC 2500 times, or 80% dichlorvos EC 1000 times solution, or 10% of 3000 Chlorformin Emulsion EC Spray. 3.6 Tea yellow medlar 0.3% Qijing 200 times, or 37% chlorine horse cream 200 times spray. 4 harvest the best batch of harvested precooked red fruit, the whole plant red cooked and then unplug the whole plant, put it in the ground to dry, wait until the dried leaves after drying, the roots of the pepper pods tied to the root bundle, with corn stalks For the bottom, the bundled peppers are weighed and tamped, flipped every 8 to 10 days, and picked after the end of November or early December.
