为充分挖掘玉米增产潜力,发挥增产优势,夏玉米生产在做好耐密高产品种选用、播前残茬处理、普遍增施钾肥、病虫草害防治和田间科学管理等工作的基础上,要突出落实好“抢时早播”、“密植防倒”、“重追穗肥”、“适期晚收”四个方面的技术工作。一、选好品种要选用紧凑、耐密高产品种。各地可根据当地生态条件和生产情况,选择适合在当地种植的高产、耐密优良玉米品种。二、抢播早浇针对我市夏玉米生长季节短、光热资源不足、籽粒灌浆时间短等问题,在小麦收获后要抢
In order to fully tap the yield potential of corn and give play to the advantages of yield increase, the summer corn production should make prominent efforts on the selection of high-density and high-yielding varieties, treatment of stubble before sowing, general increase of potash fertilizer, prevention and control of pests, diseases and weeds and field scientific management To implement the technical work of “grabbing early sowing”, “planting and protecting”, “rehearing spike fertilizer”, and “reimbursement for late harvest”. First, choose a good variety to choose a compact, resistant to dense varieties. According to the local ecological conditions and production conditions, select suitable for the local cultivation of high yield, tolerance and good corn varieties. Second, pre-broadcast broadcast against the city’s summer corn growth season is short, lack of solar thermal resources, short grain filling and other issues, after the wheat harvest to grab
