摘要:
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 。

AbstractTaking 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 different densities. The results showed that the yield with one plant per hole was the highest under the density of 5 000 plants per 666.7m2, and that was second with two plants per hole under the density of 6 000 plants per 666.7m2; the difference between them was not significant, and the latter was more labour saving.

冀中南地区是粮棉集中产区,人多地少,土地资源有限,粮棉争地矛盾突出,发展麦(菜)棉两熟是缓解粮棉争地矛盾的有效途径。棉花轻简化育苗麦后移栽技术,在棉区实现了一熟变两熟,促进了种植制度改革。当前国内麦棉两熟栽培方式主要有两种:麦棉套种和麦后直播棉、麦后移栽棉。麦套棉由于二者共生期长,不利于机械采收,麦后直播棉产量不理想,麦后移栽棉则有效弥补了棉花生长所需有效积温和生育期不足的短处, 提高了棉花产量和品质。为了进一步完善麦后移栽棉的高产栽培技术,笔者在总结以往研究的基础上,设置不同密度不同栽培方式试验,旨在获得冀中南地区早熟棉品种适宜的种植密度和高效的种植方式,为大面积推广麦后移栽棉提供技术依据。
