How to plant colored sweet peppers in spring? If there are any points to pay attention to, please refer to the following methods for planting colored sweet peppers in spring: variety selection and seedling raising: colored sweet peppers should choose varieties with strong disease resistance, easy cultivation and high yield, such as our company's Manqi and Kagino. Sow seeds in hotbeds or build beds in winter-warm greenhouses. Soak the seeds in 55 ℃ warm water for 15 minutes before sowing to remove germs from the seeds. After soaking the seeds, they were placed under 25-28 ℃ to accelerate germination, and when 60% of the seeds germinated, they could be sown. The day before sowing, pour a permeable water into the nutrition bowl, wait for the water to seep, point a germinated seed in each bowl, and then cover it with a layer of sifted fine fluvo-aquic soil about 1 cm thick. In order to prevent bacteriosis, 5 grams of carbendazim wettable powder is added to every square meter of covered soil. After sowing, the daytime temperature is 30-35 ℃, the night temperature is not less than 20 ℃, and the daytime temperature after emergence is 25-30 ℃ and not less than 15 ℃ at night, which is beneficial to strong seedlings. Planting: the small arch shed with grass grass was planted in the early and middle of March. The small arch shed and the middle arch shed without grass cover were planted in the middle and late March. When planting, the ground temperature of 10 cm in the shed is required to be stable at 10-12 ℃. The seedling age is 60-75 days, the plant height is about 20 cm, and the number of leaves is 8-10. The soil should be ploughed deeply before planting, combined with the application of base fertilizer, the application rate per mu is as follows: high-quality ring fertilizer 5000-7000 kg, rotten human manure or chicken manure 150,200kg, calcium superphosphate 80120kg, potassium sulfate 20kg. Adopt high border or small high border, high ridge, wide and narrow row or single row, row spacing 55-65 cm, plant spacing 4O-60 cm, planting 2000-2500 plants per mu. Pruning method: leave 2 main branches per plant and remove lateral branches. The lateral buds of the middle branches can be taken properly, leaving 3-4 leaves and then taking the top, leaving 7-9 main branches per square meter. Management: no ventilation after planting to before slow seedling, greenhouse temperature control: 25-30 ℃ in daytime, 16-18 ℃ at night. Proper ventilation after slow seedling, greenhouse temperature: 23-28 ℃ during the day, not less than 15 ℃ at night, sunny and warm weather during the period, uncover the greenhouse film at noon and ploughing 1-2 times. If the base fertilizer is insufficient, it can be topdressing once, and watering should be controlled when the door pepper blossoms, and it can be ploughed twice. When the plant is in blossom, in order to prevent flowers and fruits from falling and ensure normal fruit setting, coat the fruit stalk with 10-20 mg / L 2jue 4rel D or spray it with 25-30 mg / L tomato spirit. After the gate set fruit, a large topdressing was carried out, and 15 kg of ternary compound fertilizer was applied per mu. After fertilizing, paddle and hoe once and water once. Greenhouse temperature control: 21-26 ℃ in daytime and no less than 15 ℃ at night. Increase ventilation during the day as the weather gets warmer. When the temperature is stable above 20 ℃ during the day, the greenhouse film can be opened and covered in the evening. Door pepper and pepper should be harvested early to avoid falling seedlings. After the first ten days of May, when the temperature is stable above 15 ℃, the small scaffolding can be removed. After the pepper is harvested, topdressing the pepper again, applying 15kg urea per mu. After that, topdressing every 20 days and watering every 5-6 days. Into the summer, timely drainage after rain, combined with pulling grass to cover the border to prevent the soil temperature from being too high and preserve soil moisture. Control aphids with 2500 times of aldicarb (aphid mist) wettable powder, control cotton bollworm and tobacco green insects with 2500 times of phoxim emulsion, spray tea yellow mites with 2500 times solution of insecticidal alum, and prevent epidemic disease with 500 times solution of disinfectant alum. The diseased plants should be pulled out immediately and buried deeply. Click to get more sweet pepper planting techniques click to get more vegetable planting techniques
