不同化学药剂处理对长绒棉封顶效果的影响
Analysis of the influence of different chemical treatments on the sealing effect of long staple cotton
摘要
Abstract
[Objective]To study the effect of chemical detopping on long-fiber cotton in the hope of pro-viding 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 compo-nents,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"Mianfeng-ding"and Manual topping separately high 1.5units,1.8untits.boll number per plant of"Yiding"and"Yi-ding"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"Guoguang-guandingtaocan"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"Mianding-feng"treatment by 15.4％,16.0％,20.8％,21.2％and 22.9％,the strength and the length uniformity in-dex had little difference,but it was significant for the micronaire value and length.The comprehensive evalua-tion of fuzzy method showed that the comprehensive performance of"Yiding","Yiding","Guoguangguand-ingtaocan"and"Xianglingzhuan"was better than artificial detopping.[Conclusion]The plant height incre-ment of chemical capping treatment is larger;chemical detpping has a significant effect on yield and yield com-ponents,micronaire value and length;"Yiding"treatment effect is the best,"Yiding","Guoguangguanding-taocan"and"Xianglingzhuan"treatment effect are second.关键词
