摘要:

【目的】 分析不同化学药剂处理对长绒棉封顶效果的影响,为集成长绒棉化学封顶配套技术提供支撑。【方法】 采用完全随机试验设计,供试长绒棉品种为新78,分析“易顶”、“抑顶”、“向铃转”、“施益富”、“棉顶封”、“国光冠顶套餐”、人工打顶7个不同处理对棉花株高、产量及产量构成因子、主要纤维品质及成本的影响。基于熵权的模糊综合评价法,评价各处理的11个长绒棉性状。【结果】 化学封顶剂处理封顶前后长绒棉株高增长量变幅为16.1~40.9 cm,而人工打顶3.1 cm;“易顶”处理的单株果枝数较“棉顶封”和人工打顶分别高1.5台、1.8台;“易顶”、“抑顶”处理的单株铃数显著高于“施益富”、“棉顶封”和人工打顶处理,“施益富”处理铃重较“国光冠顶套餐”处理显著高0.23 g,“易顶”处理衣分比人工打顶、“抑顶”、“施益富”处理显著高1.1、1.2、1.3个百分点,“易顶”处理籽棉产量较“施益富”、人工打顶和“棉顶封”处理显著高16.4%、17.4%、20.8%,“易顶”处理皮棉产量比“国光冠顶套餐”、“向铃转”、“施益富”、人工打顶和“棉顶封”处理显著高15.4%、16.0%、20.8%、21.2%、22.9%;不同处理间断裂比强度、长度整齐度指数差距不大,但对上半部平均长度、马克隆值影响显著。“易顶”、“抑顶”、“国光冠顶套餐”和“向铃转”综合表现优于人工打顶。【结论】 化学封顶处理株高增长量较大;化学封顶对单株果枝数、产量及产量构成因子、马克隆值和上半部平均长度影响显著;“易顶”处理效果最优,“抑顶”、“国光冠顶套餐”和“向铃转”处理效果次之。

Abstract:

【Objective】 To study the effect of chemical detopping on long-fiber cotton in the hope of providing theoretical support for integration matching techniques of chemical detopping. 【Methods】 The tested long staple cotton variety is Xin 78,A complete randomized experiment design was used to analyze the effects of seven detopping treatments: “Yiding”, “Yiding”, “Xianglingzhuan”, “Shiyifu”, “Miandingfeng”, “Guoguangguandingtaocan” and Manual topping on influences of cotton plant height, yield and yield components, main fiber quality. At the same time, fuzzy comprehensive evaluation method base on entropy weight was applied to evaluate the 11 characters of each treatment.【Results】 The results showed that the plant height increment of pre and post the chemical detopping and artificial detopping treatments were 16.1-40.9 cm and 3.1 cm, respectively; “Yiding”treatent number of fruit branches pe cotton plant was compare with “Mianfengding”and Manual topping separately high 1.5units,1.8untits.boll number per plant of “Yiding” and “Yiding” treatments was significantly higher than those of “Shiyifu”, “Miandingfeng” and artificial detopping treatments, the boll weight of the “Shiyifu” treatment was significantly higher than that of the “Guoguangguandingtaocan” treatment by 0.23 g, lint percent of “Yiding” treatment was significantly higher than that of artificial detopping, “Yiding” and “Shiyifu” by 1.1, 1.2 and 1.3percentage points,the seed cotton yield of “Yiding” treatment was significantly higher than that of “Shiyifu”, artificial detopping and “Miandingfeng” treatment by 16.4%, 17.4% and 20.8%. The lint cotton yield of “Yiding” treatment was significantly higher than those of “Guoguangguandingtaocan”, “Xianglingzhuan”, “Shiyifu”, artificial detopping and “Miandingfeng” treatment by 15.4%, 16.0%, 20.8%, 21.2% and 22.9%, the strength and the length uniformity index had little difference, but it was significant for the micronaire value and length. The comprehensive evaluation of fuzzy method showed that the comprehensive performance of “Yiding”, “Yiding”, “Guoguangguandingtaocan” and “Xianglingzhuan” was better than artificial detopping.【Conclusion】 The plant height increment of chemical capping treatment is larger; chemical detpping has a significant effect on yield and yield components, micronaire value and length; “Yiding” treatment effect is the best, “Yiding”, “Guoguangguandingtaocan” and “Xianglingzhuan” treatment effect are second.

Key words: long-fiber cotton; entropy weight; fuzzy comprehensive evaluation method; chemical detopping; effect
