Selected fine species The varieties of fresh corn in the selection of varieties should be strong in stress resistance, high in yield, and good in merchandise. The corn varieties with high content of sweet corn and lysine should be the main varieties, and be suitable for early, middle and late match. Wrong time broadcast, listing conditions to create conditions. Seed coating before sowing to prevent underground pests. Timely early broadcast To carry out nursery transplanting and mulching cultivation mode, in the sowing date, to grab the early grasp, early spring sowing of fresh corn should not be too late to facilitate the early listing; autumn should be appropriate late broadcast, about mid-October listed to meet market needs . Isolation planting Time isolation, sowing date of more than 30 days; spatial isolation, above 500 meters, because sweet corn and high-lysine corn are not isolated from normal corn, ie lose the characteristics of high-lysine corn and sweet corn and lose their significance. Therefore, it is necessary to isolate planting and prevent string of powder. Reasonable dense planting It is necessary to plant densely and rationally so that the individual and group structure is reasonable so as to facilitate ventilation and light transmission, reduce empty stalks, promote good fertility and early maturation. If the density is too large, the ear is small, the panicles are easy to appear, and irregular or empty stalk rates will occur. High phenomenon, if the density is too small, the output of the ear is small, the efficiency is low, and the income is small, so it is necessary to properly plant the plant according to the characteristics of the variety, the quality of the soil, and the amount of fertilization. Scientific fertilization The first is to increase organic fertilizer, mainly based fertilizer, 4000-5000 kg per mu, and also apply N, P, and K fertilizers to combine organic, inorganic, and micro-fertilizers, and nitrogen, phosphorus, and potassium. The second is skillful application of fertilizer, mainly diammonium phosphate, about 10 kilograms per mu, the third is early dressing, acres of urea about 15 kilograms, top dressing time in corn needs fat, that is, the jointing period began. Fresh corn is best applied organic fertilizer and biological fertilizer, per acre applied fermented fresh chicken manure 2000 kilograms, as the base fertilizer, fertilizer can be used for cake fertilizer, fertilizer effect is high, long duration, there is a stamina, mu cake fat 150 kg. Strengthen management One is early morning seedlings, early set seedlings, early make-up seedlings, seedlings seedlings seedlings uniform, and do a good job of cultivator weeding, and second, drought and irrigation, encounter water drainage, the third is to prevent disease. 3PLY Disposable Protective Mask Fold Flat Face Mask,Anti-Virus Surgical Mask,Disposable Protective Mask,3Ply Disposable Protective Mask Ningbo Autrends Prevention Products Co., Ltd , https://www.autrendsafety.com
