在确定三麦播种量时,群众惯用以密取胜的经验。但有些田块用种量太大,甚至稀茬麦也播密茬麦的种量,其结果是穗多、穗小、粒小,产量不高。近几年来报导了不少三麦高产栽培以小播量夺高产的经验后,大面积生产上又有大减播种量的做法,结果有的也不太理想。为解决大面积生产上合理确定播种量的问题,1979年秋播期间组织部分公社农科站进行了有关试验。
In determining the sowing of three wheat, the crowd used to win the winning experience. However, some plots with too much seed, and even stubble stubble stubble crop wheat, the result is spike, spike, small grain, yield is not high. In recent years, many high-yielding cultivars of Sanmai have been reported to experience high yields after sowing them. In the meantime, there has been a drastic reduction in seeding yields in large-scale production and the results are not quite satisfactory. In order to solve the problem of judging the sowing amount reasonably in a large area production, some experiments were conducted during the autumn 1979 broadcasts of some commune agricultural stations.
