不同密度不同种植方式对麦后移栽棉产量的影响

Effects of Different Planting Densities and Patterns on Yield of Cotton Transplanted after Wheat

以邯郸市农业科学院育成的转基因抗病虫早熟棉品种邯686为试验材料,在田间设置6个不同处理,研究每穴单株和每穴双株在不同密度下的种植效果。结果表明:666.7m2每穴单株种植5 000株籽棉产量最高,每穴双株种植6 000株处理产量第二,两者差异不显著,后者更加省工。

Taking transgenic early - maturity cotton variety Han 686 with diseases and pests resistance as material, six different treatments were set to study the planting effects of one and two plants per hole under dif- ferent densities. The results showed that the yield with one plant per hole was the highest under the density of 5 000 plants per 666.7m^2, and that was second with two plants per hole under the density of 6 000 plants per 666.7m^2 ; the difference between them was not significant, and the latter was more labour saving.
