1 蕾期整枝技术 目前,虽进行化学调控,但由于叶枝生长势强,耗养分多,而且影响通风透光,若不打叶枝易造成棉花的徒长、荫蔽,不利于花铃期管理。去叶枝原则是“去早、去小、去了”。方法为:第一果枝出现后,及时去掉下部叶枝,同时把主茎上的病叶、黄叶摘除,群众俗称“捋裤腿”。对于行距过大或苗少不能充分利用地力、光照的棉田,如:与大蒜、葱头等间作棉田或出苗差、缺苗严重的棉田
1 buds pruning technology At present, although the chemical regulation, but because of the strong growth of leaf branches, nutrients and more, but also affect the ventilation and light, if not easy to hit the branches of cotton caused by leggy, shady, is not conducive to flowering management.
