Seedling raising technique of Spring sowing Pepper

(1) Yangqi is prepared to select fertile land, leeward sunny, no eggplant, tomato plots in the previous crop, and build Yangqi. Each planting mu, according to the seed amount of 150 grams for seedling, Yangqi should be more than 10 square meters. Apply enough base fertilizer, water to build soil moisture, and use a small amount of urea, phosphorus and active potassium fertilizer. Because Yangqi seal, do not apply ammonium bicarbonate, ammonium sulfate as base fertilizer, in case ammonia harm seedlings. For heavy soil viscosity, poor permeability of the seedbed, can apply some fly ash. (2) seed treatment fully turning and drying the seeds one day before sowing, soaking the seeds in 1500-fold solution of carbendazim and 1000-fold 10% trisodium phosphate aqueous solution for 10 minutes, washing with clean water, soaking the seeds in warm water at 50-60 DEG C for 4 hours, covering the seeds with damp cloth for germination for 24 hours after draining. (3) Sowing procedures: watering soles, fertilizing, leveling the land--evenly sowing--covering 0.5-0.8 cm of fine soil, not more than 1 cm, then covering with plastic film--covering the sunny bed with plastic film tightly, controlling the temperature at about 25℃ during the day and 12-15℃ at night. After 60-70% emergence, remove the mulch. Pay attention to moisture, spray water evenly from a fine spray can to increase humidity, and avoid flooding. (4) Seedling management When seedlings are 3-4 leaves, they should be thinned in time, weak seedlings removed, and weeds removed. In the later stage, attention should be paid to the prevention and control of aphids, which can be sprayed with imidacloprid, carbendazim or thiophanate-methyl and viridin to achieve the purpose of treating both diseases and insect pests and ensure the cultivation of strong seedlings and disease-free seedlings. Strong seedling standard: stem thick internode short, leaves thick color dark, stem and leaf integrity without disease and insect pests, developed root system white lateral roots, planting 8 leaves. About 15 days before planting (early April), let the seedlings out of the top of the sunny bed to gradually adapt to the open field environment and prepare for planting. At the same time, water the sunny beds before planting to reduce damage to the roots when transplanting seedlings. Practice has proved that cultivating strong seedlings, planting strong seedlings and no disease and insect seedlings are the fundamental guarantee for high yield and harvest of pepper. And most farmer seedling stage does not have the habit of controlling insect to prevent disease, this should cause broad pepper farmer attention.
