broadcast sowing

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.

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；
