摘要
为探讨南疆棉区棉花化学打顶技术,以减轻棉花栽培的劳动强度,作者于2013年在新疆生产建设兵团第三师农业科学研究所试验基地,利用烟草抑芽剂氟节胺进行棉花化学打顶试验。结果表明:施用氟节胺处理与对照相比,在一定程度上可有效控制棉株的生长;其产量略低于对照,株高高于对照,果枝层数增加,但空果枝数、脱落数增多;绒长变短,不孕籽率增多,单铃重量轻。
In order to investigate the chemical topping technology in Southern Xinjiang cotton region, reduce the labor intensity of cotton cultivation, the author used tobacco bud inhibitor flumetralin to have cotton chemical topping test in the Xin- jiang production and Construction Corps of third divisions of Agricultural Science Research Institute experimental base in 2013. The results showed that： application of flumetralin treatment compared with the control, could effectively control the cotton growth to certain extent; the yield was lower than the control, plant height was higher than that of the control, branch number increased, but the empty fruit branch number, falling number increased; long pile becomed shorter, the rate of sterile seeds increased, single boll weight.
