摘要
昌图县是全国著名的商品粮基地,实施机械精量播种技术能够达到苗齐、苗全、苗壮,节约粮种,减少用工,提高粮食产量的目的。通过与机械精少量播种进行对比试验,结果表明:机械精量播种较机械精少量播种节省种子2.0kg/667m2;采用机械精量播种的玉米田平均产量比精少量播种产量增加167kg/667m2,增产幅度为25%,增产效果显著,可达到节本增效的目的,适于昌图地区大面积推广应用。
Changtu County is a famous commodity grain base in China. The application of precision sowing is capable of helping seedlings grow evenly and healthily,saving seeds and labors,and increasing yields. Comparative experiments were conducted which showed that mechanized precision sowing can save seedlings of 2.0 kg/667 m2 than accurate and smidgen sowing,and the average yields increase 167 kg/667 m2 accounting for 25%. The experiment statistics indicate that the technique of precision sowing is suitable for Changtu area.
