小麦机械半精量播种,是山东省农业大学余松烈教授提出的一项冬小麦高产栽培技术。它是在地力较高、水肥条件较好的地块上,采用机械半精量播种技术,较好地处理群体与个体发育的矛盾,改善群体内有效蘖的光照条件,使个体营养良好,成穗率高,单株穗多,穗大粒多,粒饱,从而获得高产的栽培技术。多年来,我区小麦生产是靠增加下种量来提高单产的。这在低产变中产阶段是可行的。进入中产 Wheat machinery semi-precision sowing, Shandong Province Agricultural University Professor Yu Songlie proposed a high-yielding winter wheat cultivation techniques. It is in the higher fertility, water and fertilizer conditions of the land, the use of mechanical semi-precision sowing technology, and better handle the contradictions between groups and individuals to improve the effective tillering of the group of light conditions, the individual nutrition is good, into Spike rate, per plant spike, spike large grain, grain full, so as to obtain high-yielding cultivation techniques. For many years, wheat production in our district has been increased by increasing the yield of wheat. This is feasible in low-yielding middle class. Into the middle
