Techniques for raising seedlings of Spring sowing Pepper

(1) the sunny beds are going to choose plots where the land is fertile, leeward and sunny, and there are no eggplant or tomatoes planted in the previous crop to build sunny beds. For every mu of planting, seedlings should be raised according to 150 grams of seeds, and the sunny border should be more than 10 square meters. Apply sufficient base fertilizer, make soil moisture by flood, and use a small amount of urea, phosphate fertilizer and active potash fertilizer. Because the sunny border is sealed, do not use ammonium bicarbonate and ammonium sulfate as base fertilizer to prevent ammonia from harming the seedlings. For the seedbed with poor soil viscosity and poor permeability, some ash powder can be applied. (2) fully turn the seeds one day before sowing, soak the seeds with 1500 times carbendazim and 1000 times 10% trisodium phosphate aqueous solution for 10 minutes, rinse with clean water, soak the seeds with 50 ℃ 60 min warm water for 4 hours, drain and cover the seeds with damp cloth for 24 hours. (3) watering the bottom water in the sowing procedure, fertilizing and leveling the land-evenly sowing-covering fine soil 0.5 cm, not more than 1 cm, and then covering the sunny bed with plastic film-- the temperature should be controlled at about 25 ℃ during the day and 12 ℃ at night. Remove the mulch film after 60% of the seedling emerges. Pay attention to moisturizing, can be used to spray water evenly, in order to improve humidity, do not flood irrigation. (4) Seedling management when seedlings have 4 leaves, time should be given to seedlings, weak seedlings should be removed and weeds should be removed. In the later stage, attention should be paid to the prevention and control of aphids, which can be sprayed with imidacloprid, carbendazim or methyl topiramate, to achieve the purpose of treating both diseases and pests, and to ensure the cultivation of strong and disease-free seedlings. Strong seedling standard: the stem is thick, the internodes are short, the leaves are thick and dark, the stems and leaves are intact without diseases and insects, the roots are developed and the lateral roots are white, and there are 8 leaves when planting. About 15 days before planting (early April), the seedlings were released from the top of the sunny bed to make the pepper seedlings gradually adapt to the open environment and prepare for planting. At the same time, water the sunny border before planting in order to reduce the damage to the root system during seedling transfer. Practice has proved that cultivating strong seedlings, planting strong seedlings and disease-free seedlings is the fundamental guarantee for high yield and harvest of pepper. And most farmers do not have the habit of pest control and disease prevention at the seedling stage, which should attract the attention of pepper farmers.
