我州冬小麦播种面积较大,占全州耕地面积的50%,多年来农民用种量较大,因群体密度大,丰产田往往出现全优现象造成大幅度减产,通过精耕细作精量播种省种120～150kg/hm2,降低生产成本,发挥个体效益,提高冬小麦的抗倒能力来达到丰产目的,笔者通过进行不同播量对比试验,用种量150～180kg/hm2为宜,比常规增产750～1500kg/hm2。
Mycountry winter wheat sown area larger, accounting for 50% of the state’s arable land area, farmer over the years with a large amount of population density due to large groups of fertile fields tend to appear full-gifted phenomenon resulting in significant reduction of production, precision intensive planting by province 120 ~ 150kg / hm2, reduce the production cost, play an individual benefit, improve the lodging resistance of winter wheat to achieve the purpose of high yield, the author through different sowing comparison test, with the amount of 150 ~ 180kg / hm2 is appropriate, 1500kg / hm2.
