1、整枝及推株并垄吐絮期如果棉田叶茂荫蔽，可打掉主茎下部老叶，剪掉空枝，摘去边心，以增强棉田通风透光，降低温度。同时，可减少养分无益消耗，促进棉铃正常吐絮。对荫蔽特别重的棉田，或通连阴雨，棉田湿度大，可采取“推株并垄”的办法，即趁土壤湿润时，将相邻两行棉花 1, pruning and pushing the plant and ridge bolting period If the cotton leafy shade, you can knock down the lower part of the main stem of the old leaves, cut empty branches, remove the edge of the heart, to enhance cotton ventilation and reduce temperature. At the same time, can reduce the useless consumption of nutrients to promote normal boll boll boll.
