保护性耕作机械化种植模式与播量试验
Experiment of Mechanized Planting Mode and Sowing Rate for Conservation Tillage
摘要
Abstract
Mechanized planting mode and sowing rate was conducted in Qingdao from 2009 to 2011. The result showed that both of the two factors had significant influence on wheat yields. The wheat yields in small-wide-narrow mode (28 cm +12 cm) was the highest, which is 15% ~30% higher than the large-wide-narrow mode and large-equal-row mode. When the sowing rate increased by 10% ~ 20% , the yield increased by 2, 2% ~ 15%. The reason of yield increasing in small-wide-narrow mode and yield decreasing in large-wide-narrow mode was analyzed.关键词
