摘  要：
【目的】比较新疆北疆棉区不同打顶方式下棉花植株农艺性状及产量的变化,为生产上推广应用植物生长调节剂对棉花进行化学免打顶技术提供参考依据。【方法】选用新陆早33号、新陆早45号和新陆早46号3个品种,设置喷施氟节胺化学打顶、人工打顶和不打顶3个处理,测定3个处理条件下棉花植株农艺性状和产量的变化,分析化学免打顶技术的打顶效果及对棉花产量的影响。【结果】棉花喷施化学打顶剂植株高度显著高于人工打顶,但显著低于不打顶植株,但主茎节数及果枝数化学打顶植株显著高于人工打顶;果枝长度低于人工打顶植株,株型较为紧凑;化学打顶棉花上部果枝结铃数及内围铃数略高于人工打顶,但铃重显著高于人工打顶,籽棉和皮棉与人工打顶相当。【结论】喷施化学打顶剂氟节胺能有效控制棉花植株顶尖的生长,具有打顶效果,同时使得棉花株型更为紧凑。

摘  要：
【Objective】To study the agronomic and economic characters of cotton by using different topping measures in Xinjiang cotton area and to explore the problems in chemical topping and provide theoretical basis for chemical topping.【Method】Xinluzao 33,Xinluzao 45 and Xinluzao 46 were used as test materials, chemical topping,manual topping,on- decapitation were set up to study the cotton agronomic and economic characters change under three kinds of topping measure.【Result】Chemical topping cotton height was significantly higher than that of the manual topping and lower than that of the non- decapitation,but the number of main stem nodes and fruiting branches was significantly higher than that of the manual topping. Fruit branch length was below the manual topping,and thus more compact plant type. The boll number upon fruiting branch and the inner boll number treated by chemical topping is slightly higher than that of the manual topping,and there was a significant difference in boll weight. The yield of the seed cotton and ginned cotton was roughly the same of that of the manual topping. 【Conclusion】Fluorine could effectively control cotton top growth and meanwhile made cotton plants more compact.
