摘要
目前新疆兵团棉区机械化管理已达到较高水平,但打顶作为棉花栽培管理的一个关键环节,仍无法摆脱手工操作,成为棉花生产全程机械化和规模化的限制因素。化学打顶是利用植物生长调节剂强制延缓或抑制棉花顶尖的生长,从而达到调节营养生长与生殖生长的目的。目前新疆兵团用于棉花化学打顶整枝的药剂品种主要是氟节胺和甲哌鎓。加快制定出一套棉花化学打顶整枝药剂综合配套技术规程,对于显著提高兵团棉花全程机械化水平,扩大规模化种植及可持续发展具有重要意义。
The mechanization of cotton-growing areas has reached a higher level in Xinjiang Production and Construction Corps, but topping as a key part of the cotton cultivation, still cannot get rid of manual operation, it has become the limiting factor for cotton full mechaniza- tion production in Xinjiang. Chemical topping is the use of plant growth regulator to inhibit the growth of cotton-top, so as to achieve regulates vegetative and reproductive growth. The varieties of agrochemicals that used for cotton topping are mainly flumetralin and mepiquat chloride in Xinjiang Production and Construction Corps. Speeding up the establishment of technical regulations of chemical topping on cotton, that is significant to improve the mechanization of cotton cultivation, expand the large-scale cultivation and promote sustainable development of cotton production.
