摘要
2009—2011年在青岛开展了保护性耕作机械化种植模式与播量试验。试验表明两者对产量均有显著影响,小宽窄行模式(28 cm+12 cm)小麦产量最高,分别比大宽窄行和大等行距模式高15%～30%;加大10%～20%的播量,产量提高2.2%～15%,并分析了小宽窄行模式增产和大宽窄行模式产量不高的原因。
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.
