一、选用优质高产多抗新品种良种是提高麦茬玉米产量和改进品质的内在因素,随着超级玉米新品种的培育成功,良种的增产作用将更加明显。在生产中必须选用适应性广、抗倒、抗病能力好、增产潜力大、生长势强的一代杂交种。如郑单958、浚单22、中科11、登海605、伟科702等。播前要对种子进行精选,去掉破碎,发霉变质籽粒和秕粒,留下整齐均匀的饱满籽粒,剔除越年陈种子。二、种子包衣种子包衣可以起到晒种和拌种两种作用,具
First, the selection of high quality, high yield, multiple resistance new varieties of seeds is to improve the yield of wheat stubble and improve the quality of internal factors, with the successful cultivation of new varieties of super corn, improved seed yield will be more obvious. In the production must choose a wide adaptability, anti-down, disease resistance, yield potential, growing strong generation of hybrids. If Zhengdan 958, Xundan 22, Branch 11, Denghai 605, Weike 702 and so on. Seeds before sowing selection, remove broken, moldy grains and grains, leaving a neat and tidy seeds, remove the more annual Chen seed. Second, the seed coating Seed coating can play a kind of drying and seed dressing two functions, with
