1玉米精量播种的优点1.1节省种子,降低成本传统的播种方式,达到国家标准的种子需要45.0~52.5kg/hm2,而精量播种只需要6.00万~6.75万粒/hm2,用种量19.5~22.5kg/hm2,比常规播种节省22.5~30.0kg/hm2,降低了生产成本。1.2省工、省力,降低了劳动强度精量播种,一次播种保全苗,不用间苗、定苗,同时施用缓控释肥,减少了追肥的环节,这样农民外出打工,家中留守人员就能做好剩余田间操作,降低了农民的劳动强度,节约人工费用,同时外出打工,相对增加
1 The advantages of corn precision sowing 1.1 Save seeds and reduce costs Traditional sowing methods to meet the national standard of seeds need 45.0 ~ 52.5kg / hm2, and precision sowing only 60000 ~ 67500 / hm2, with the amount of 19.5 ~ 22.5kg / hm2, saving 22.5 ~ 30.0kg / hm2 than the conventional sowing, reducing the production cost. 1.2 labor-saving, labor-intensive, reducing the intensity of precision sowing, a seedling security seedlings, without seedlings, Dingmiao, while the slow-release fertilizer application, reducing the top-dressing link, so farmers go out to work, the home stay staff will be able to do a good job Field operations, reducing the labor intensity of farmers, saving labor costs, while working out, a relative increase
