冬小麦撒播简化高产栽培技术的研究与应用

Study on the Technique of High Yield Cultivation With Broadcast Sowing and Simplification and Application in Winter Wheat

通过对小麦撒播栽培技术及其增产机理进行系统研究 ,结果表明 ,撒播栽培利于冬前幼苗生根增蘖 ,提高成穗率 ;后期单茎绿叶面积大 ,光能利用率高 ,利于提高粒重 ;同时具有省力、省工、简化栽培的特点 。

The technique of cultivation with broadcast sowing and the mechanism of increase production in winter wheat were studied systematically. The results showed that cultivation with broadcast sowing could be of advantage to rooting and tillering of seedling before winter, and increase the percentage of ear bearing tiller. There were more large green leaf area of single stem and higher utilized coefficient of light energy than that of conventional sowing in drill in the late of growth. It could improve grain weight. The advantage was easy to raise and save labour to achieve high yield and benefit.
