棉花通过整枝,能够调节营养,减少消耗,改善通风透光条件,从而抑制徒长,减少蕾铃脱落,防止烂铃,提高前期结铃率,以及棉花的品质和产量。据我们试验,精细整枝的棉株,单株结铃一般比对照增加1.2～2.4个,单铃籽棉重增加0.14～0.4克,籽棉产量增加10%以上。棉花整枝,包括去木枝、摘顶心、抹赘芽、打边心、去老叶和剪空枝等几项工作。 Cotton through pruning, can regulate nutrition, reduce consumption, improve ventilation and light conditions, thereby curbing leggy, reducing the loss of buds, prevent bad bell, improve the early boll rate, and cotton quality and yield. According to our experiments, fine pruning of cotton plants, bolls per plant generally increased 1.2 to 2.4 compared with the control, single boll seed cotton weight increased 0.14 ~ 0.4 grams, seed cotton yield increased by 10% or more. Cotton pruning, including to the wood, pick the top heart, wipe the bud, hit the edge of the heart, to the old leaves and cut a few branches and other work.
