精量播种是农作物播种技术进入新的历史阶段的一个重要标志。从当前看,通过精量播种,可以节省大量用种,解决因受灾而造成的种子量不足问题,特别是可以解决高产作物面积大同良种不足的矛盾,从而扩大良种利用面积,充分发挥良种(尤其是杂交种)的增产优势,为我省1983年再夺粮豆三百亿斤创造条件。从长远看,精量播种是农作物种植向标准化、规范化方向发展的必然趋势,精量播种不仅可以节省种子,节省用工、降低生产成本、而且有利 Precision sowing is an important symbol of crop sowing technology entering a new historical stage. At present, through precision sowing, large numbers of seeds can be saved so as to solve the problem of lack of seeds caused by the disaster, and in particular, it can solve the contradiction between the shortage of high-yielding crops and the breeding of good seeds (especially Is a hybrid) increase production advantage, for the province in 1983 to seize the grain 30000000000 pounds to create the conditions. In the long run, precision sowing is an inevitable trend of standardization and standardization of crop planting. Precision sowing can not only save seeds, save labor, and reduce production costs, but also benefit
