摘要: 【目的】 研究新型脱叶剂欣噻利在新疆奎屯棉区的使用效果。【方法】 以Z1146为材料进行脱叶剂试验,采用方差分析法和灰色关联度综合评价法,综合评价新型脱叶剂欣噻利不同处理的棉花脱叶率、吐絮率、产量及纤维品质。【结果】 喷施噻苯隆+乙烯利(450 g/ hm2+2 250 mL/hm2)、欣噻利(1 800~2 700 mL/hm2)均能明显提高棉花脱叶率,且催熟效果较好。喷施脱叶剂对棉花纤维长度、整齐度指数和马克隆值无显著影响,对产量和棉纤维断裂比强度有一定影响。不同处理综合性状优劣排序为T5>T4>T3>T6>T1>T2,其中T5处理的综合评判值最高,为0.861 6。【结论】 T5处理(欣噻利4:1 350+1 350 mL/hm2分2次喷施)具有较优越的综合性能,适宜在新疆奎屯棉区推广。

Abstract: 【Objective】 In order to study the effect of the new defoliant Xinsaili in Kuytun area, the defoliation test was carried out with Z1146 as the test material.【Method】 The defoliation rate, boll opening rate, yield and fiber quality of the new defoliant Xinsaili were studied by variance analysis and grey relational comprehensive evaluation.【Result】 Spraying Saibenlong + ethephon (450 g/hm2+2,250 mL/hm2) and Xinsaili (1,800-2,700 mL/hm2) significantly improved the defoliation rate of cotton, and the ripening effect was better. In terms of cotton yield and cotton fiber quality, spraying defoliation had no significant effect on cotton fiber length, uniformity index and micronaire, but had certain effect on cotton yield and breaking tenacity. The comprehensive traits of all treatments were evaluated by grey correlation method. The order of comprehensive traits of different treatments was T5 > T4 > T3 > T6 > T1 > T2. The comprehensive evaluation value of T5 treatment was the highest, which was 0.861,6.【Conclusion】 T5 treatment (Xinsaili 4: 1,350 +1,350 mL/hm2 sprayed two times) has superior comprehensive performance and is suitable for promotion in Kuytun cotton area.

Key words: cotton; Xinsaili; variance analysis; grey correlation degree
