Cultivation type small shed Vegetables Assortment Solanum -> Chili Suitable variety Sujiao No. 5, Zaofeng No. 1, Xiangyan No. 1, and Luojiao No. 4. Cultivation Techniques 1. Nursery (1) Determine the appropriate sowing date Proper sowing is the key to nurturing strong seedlings. Early sowing, serious virus disease, low yield; too late sowing, affecting the normal development of pepper seedlings, flowering results late, the results are few, and the late low temperature is not conducive to fruit enlargement. According to the practice, the suitable sowing period in southern Jiangsu and southern Jiangsu is in early August. (2) Seedbed selection and treatment Sowing seedbeds should be selected for high dryness, convenient drainage and irrigation, good ventilation, low natural temperatures, and no loquat vegetation should be planted on the former loquat. For each 1/15 hectare, on-demand seedlings require about 40 square meters of seedbeds, an average of 5 kg of high-quality organic fertilizer applied to the seedbed per square meter, 100 g of NPK fertilizer, 10% of 25% trichlorfon powder, and 40% of aluminum phosophophate wettability. Powder or 50% carbendazim wettable powder 10 grams, mixed with ground, ploughed into the soil, made into a width of 1 ~ 1.2 meters of nursery pot. (3) Seed processing Seed drying before sowing 1 to 2 days, then 50% carbendazim WP 400 ~ 1000 times soaking for 30 minutes, while adding appropriate amount of trisodium phosphate to kill the virus. Remove and rinse with clean water, then put in 55～60°C constant temperature water for 10 minutes, keep stirring, add cool water immediately after 10 minutes, make the water temperature drop to 30°C, then let it soak for 5-6 hours, use clean water Rinse twice, remove and drain the excess moisture and wrap it in wet gauze. Hang it in the cool place to germinate. After 5 to 6 days, when the seeds are 60% to 80% white, when the big son is rice, you can sow. (4) sowing Since sowing is at a high temperature, sowing should be done in the early morning or evening. Before sowing, the bottom water of the seedbed must be thoroughly immersed. Use a thin blade to cut the square into 10 cm squares in the bowl, plant two seeds in each square, and then cover fine soil 0.5 to 1 cm thick. Use this method is not Need seedlings. (5) Seedling management 1 Shade rain. After planting the cover soil, the upper surface of the seedling shall be immediately covered with wet grass or mulch to protect against sun damage, drought, drought and moisture. After the emergence, the cover shall be promptly removed, and then a small arch shed shall be erected to cover the shade of the shading net to cool the temperature. The perimeter of the shed shall be provided with a pest control net. Cover the film with rain and prevent rain. Do not allow rainwater to flow into the seedlings when the film is removed after the rain. 2 control fertilizer water. Autumn and winter pepper seedlings generally do not top-dressing, such as found in the deferral of seedlings, can be combined with water topdressing a small amount of urea or foliar spray 0.2% concentration of urea, potassium dihydrogen phosphate 2 to 3 times, try not to water Or after the application of watering, watering depends on the seedlings may be, when the drought can be poured with water or watering, the ground to be drenched, so that the seedlings to drink enough water, bogey water flooded without seedlings. 3 control of pests and diseases. With 75% chlorothalonil WP 600 times or 64% anti-tussive wettable powder 500 times spraying control damping-off seedling blight and blight; with 40% dimethoate 1000 times liquid control aphids and tea Insect pests; 90% trichlorfon crystals 160 grams of water plus 1 to 1.5 kilograms, mixed with 5 kg of crushed sauteed wheat bran to make baits, spread in the evening at a dose of 1.5 to 2.5 kg per 1/15 ha. Seedlings and surrounding areas prevent underground tigers, earthworms and other underground pests and rats. In particular, each time after watering spray immediately, available 40% aluminum phosphate or 50% carbendazim wettable powder 400 times the concentration of thin, seedlings, leaves, soil full spray. 2. Colonization (1) Suitable colonization When the seedlings grow to 15 to 20 centimeters, the seedling age is about 35 to 40 days, there are 5 to 7 true leaves, there are 1 to 2 branching colonization, generally in mid-late September. (2) Preparation before planting 1 Fertilize the soil. Pepper is a group of developed crops, and has strong nutrients and water absorption capacity. It uses 5,000 kg of high-quality decomposed fertilizer, 10 kg of urea, 20 kg of potassium dihydrogen phosphate and 30 kg of superphosphate per 1/15 hectare of soil preparation. Deeply pour the soil, after the target is leveled, two plutoniums with a width of 1.8 meters are to be built. The puppets shall be placed on a small arch shed, the aisle shall be left in the middle of the two rafts, and the cold ditch shall be kept on the outside. 2 build a shed. Before the planting, the arch shed should be built well. Generally, the shed is 6 meters wide, the arch height is 1.8-2 meters, and the length of the shed is determined depending on the area. Generally, the east-west direction is adopted, the shed film is fastened, and the high-temperature shed is kept for 2 to 3 days. 3 planting density. Colonization should be conducted in the sunny afternoon. The seedbed should be watered ahead of schedule in the morning, and the original planed seedlings should be raised. Planting spacing is 35 centimeters, plant spacing is 40 centimeters, and 4000 to 4500 shoots per 1/15 ha. 3. Post-planting management (1) Temperature management. After the seedlings have been planted for a period of time, the temperature in the arch shed is high, and the ventilation and cooling are required. The temperature in the shed is controlled at 25 to 30°C during the day and 15 to 18°C ​​at night. During this period, if the weather is rainy, cover the shed to prevent rain. When the weather turns cold, it is necessary to cover the shed film at night and stamp the shed with a small shed. After mid-October, when the night temperature falls below 10°C, the grass shed should be covered in a small shed, so that the temperature of the small shed at night is not Less than 15°C to facilitate flowering, pollination, fruit setting and plant growth. After mid-November, when the weather turns cold, pay attention to anti-freeze. During the day, the ventilation time will gradually become shorter and the ventilation volume will gradually decrease. After the snow falls, the weather will be cold and will only pass through small winds in the noon. After mid-December, it will enter the cold winter season. Insulation of the shed, the film and grasshopper on the small arch shed in the arch shed, will be exposed early cover, in order to facilitate the insulation, if necessary, at night and then covered with a layer of film insulation on the small arch, so that the temperature within the small arch shed control in the daytime 22 ~ 27°C, 13°C or more at night. The minimum temperature should not be lower than 8 °C to prevent the jelly of jelly. (2) fertilizer and water management. After planting, adequate water is poured, no water is needed during the seedling period, and cultivating is performed 2 to 3 times in a timely manner. After the seedlings are water-reduced, water is poured into the soil. Water is applied every 1/15 hectares of urea in combination with watering. Ten kilograms are used as seedlings. After the door pepper sat down, water it properly and keep the soil moist. Afterwards, with the reduction of ventilation, the soil water loses its speed and slows, and the watering interval is appropriately extended, but it is still necessary to keep the soil moist. The first fruit stage and fruit stage can be combined with watering. Every 1/15 hectares is flushed with diammonium phosphate, potassium dihydrogen phosphate and urea at a rate of about 10 kilograms. The topdressing fertilizer is mainly available phosphorus and potassium, and nitrogen is not suitable. Too much, so as not to cause leggy, fallen fruit, or frost damage. (3) Plant adjustments. For weakly growing plants, the buds of the pepper can be removed and some branches removed. The result is more concentrated. After the first frost, it is advisable to set about 10 fruits per plant, remove excess buds and young fruit, concentrate nutrients, and promote fruit enlargement. If the plants are found to be long, they can spray 10 to 20 mg/kg of paclobutrazol two times after entering the flowering stage, with an interval of about 15 days to suppress the growth, adjust the plant structure, and promote flowering results. 4. reward The autumn and winter pods of hot peppers are concentrated, and generally grow from the late 11th to the early 12th. Afterwards, the temperature is reduced and the growth is slow. The grown chillies are left on the plants and fresh. Every day, the thin sheds and grasshoppers on the small sheds are uncovered. Warming the light, delaying harvesting on New Year's Day and Spring Festival. Can be marketed in batches or once harvested for the holiday market. Pest Control The virus was sprayed with 20% virus A 200-fold solution or 800-fold solution of phytoalexin; 50% Epcotinine WP 1000 times solution or 50% Sulfonyl 1500 times solution was used to control epidemics, gray mold, etc.; dicofol was used. 800 to 1000 times liquid to prevent tea and other pests.
