Abstract:

【Objective】 To improve the application effect of chemical topping agent,and to compare the application effect of flupentine and cuhuawang cotton topping agent in southern Xinjiang. 【Methods】 In 2020,three cotton varieties Xinluzhong 37,Xinluzhong 70 and Xinluzhong 82 were selected and treated with the other three treatments: artificial topping (CK),flupentine application and Cuhuawang application. Two factor split plot design was adopted.The main plot was treated with two topping agents (flupentine combined with mepiquat,Cuhuawang molding agent combined with topping agent) and artificial topping (CK),and the sub plot was treated with three cotton varieties with three repetitions. 【Result】 The proportion of reproductive organs in the main treatments on September 3 was the highest,and that in the treatment of promoting chemical king was the lowest;the proportion of distribution coefficient of vegetative organs in the main treatments on September 3 was the highest when spraying Cuhuawang,and the lowest when spraying fluthrin.Comparison among main treatments:the seed cotton yield of Xinluzhong 70 under Cuhuawang treatment was the highest than that of other varieties,and the other two varieties were the highest under fluthrin treatment;Xinluzhong 37 had the highest lint percentage under the treatment of fluthrin,the other two varieties had the highest lint percentage under the treatment of Cuhuawang,and the three varieties under the treatment of artificial topping had the lowest lint percentage.The results also showed that the average length and breaking strength of the upper part of cotton fiber were the best,while the micronaire value and elongation were the worst. 【Conclusion】 The proportion of reproductive organs under fluthrin treatments on September 3 was the highest and that in the treatment of promoting Cuhuawang was the lowest the proportion of vegetative organs was opposite to that of reproductive organs.The seed cotton yield of Xinluzhong 70 under Cuhuawang treatment was the highest than that of other varieties,and the other two varieties were the highest under fluthrin treatment;Xinluzhong 37 had the highest lint percentage under the treatment of fluthrin,the other two varieties had the highest lint percentage under the treatment of cuhuawang,and the three varieties under the treatment of artificial topping had the lowest lint percentage.While the micronaire value and elongation were the worst;The results showed that the length uniformity and yellowness of cotton fiber were the best,and the specific strength was the worst;under artificial topping treatment,the micronaire value and elongation of cotton fiber were the best,while the average length of upper part,length uniformity and yellowness were the worst.

摘要：

【目的】 比较研究氟节胺与未推广的促化王棉花打顶剂在新疆南疆的应用效果。【方法】 2020年选用新疆南疆推广的新陆中37号、新陆中70号与新陆中82号3个棉花品种,设置人工打顶(CK)、氟节胺和促化王3个主处理。采用二因素裂区设计,主区为2个打顶剂处理(氟节胺复配缩节胺,促化王塑型剂与打顶剂配合喷施)与人工打顶(CK),副区为3个棉花品种,3次重复。【结果】 各主处理下生殖器官在9月3日的占比比较,喷施氟节胺的占比最高,促化王处理下的最低;各主处理下营养器官在9月3日分配系数的占比比较,喷施促化王的占比最高,喷施氟节胺的最低。主处理间对比:促化王处理下的新陆中70号籽棉产量较其他品种最高,其余两品种棉花均在氟节胺处理下最高;新陆中37号在氟节胺处理下衣分最高,其余两品种棉花均在促化王处理下衣分最高,人工打顶处理下的3个品种衣分均为最低。比较各主处理下的品质指标,氟节胺处理下棉纤维的上半部均长与断裂比强度最优,马克隆值与伸长率最差;促化王处理下棉纤维的长度整齐度与黄度最优,比强度最差;人工打顶处理下棉纤维的马克隆值与伸长率最优,上半部均长、长度整齐度与黄度最差。【结论】 喷施氟节胺处理下的生殖器占比最高,促化王处理下的最低;而营养器官的占比两种化学打顶刚好相反。促化王处理下的新陆中70号籽棉产量较其他品种最高,其余两品种棉花均在氟节胺处理下最高;新陆中37号在氟节胺处理下衣分最高,其余两品种棉花均在促化王处理下衣分最高,人工打顶处理下的3个品种衣分均为最低。氟节胺处理下棉纤维的上半部均长与断裂比强度最优,马克隆值与伸长率最差;促化王处理下棉纤维的长度整齐度与黄度最优,比强度最差;人工打顶处理下棉纤维的马克隆值与伸长率最优,上半部均长、长度整齐度与黄度最差。
