对精选种子精量与半精量播种的试验研究

Experiment and Analysis of Mechanical Precision and Semiprecision Sowing of Selected Seeds on Yield

利用精选机械设备，对玉米种子进行精选，并按照农作物区域试验方法进行试验应用研究。结果表明，机械精选种子采用精量与半精量播种，产量表现优异，增产数量十分显著。

The maize seeds were selected with classifiers, and examined by plot test method. The results show that with mechanical precision and semiprecision sowing, the yield of the selected seeds increases significantly.
