针对生产上新推广的四种机采棉种植模式,对不同模式下棉花生长发育动态及产量性状进行比较分析。结果表明:一膜三行、一膜四行两种模式光温水肥利用率高,生长发育较快;一膜六行模式由于群体结构的支持,籽棉产量、皮棉产量最高;从栽培管理、脱叶效果等方面考虑,做好配套品种选择,一膜四行模式具有一定的推广潜力。
Aiming at the four kinds of newly-picked cotton planting models in production, the dynamic changes of cotton growth and yield under different patterns were compared and analyzed. The results showed that: one film three lines, one film four lines two modes of light and temperature water and fertilizer utilization rate, rapid growth and development; a film six lines mode due to the support of population structure, seed cotton yield, lint yield highest; from the cultivation management, Leaf effect and other aspects of consideration, do a good job supporting varieties to choose a film four lines mode has some potential to promote.
