Abstract

Abstract:

【Objective】 In order to explore the regulation effect of 0.1% thiabenduron combined with different exogenous substances on cotton growth, development, yield and quality.【Methods】 A field experiment was conducted in Dunlimai village, Hailou Township, Shaya County in 2021.Xinluzhong 67, mainly 0.1% thiabenduron 150 g / hm², was mixed with 14 hydroxybrassinolate 150 g / hm² (TDZ₁), sodium dinitrophenol 300 g / hm² (TDZ₂), prochloraz 150 g / hm² (TDZ₃), inducer 300 g / hm² (TDZ₄) and ethephon 300 g / hm² (TDZ₅), with clear water as the control (CK), The effects of 0.1% thiabenduron combined with different exogenous substances on agronomic traits, dry matter accumulation and distribution, yield and quality of cotton were analyzed.【Results】 TDZ₁, TDZ₂ and TDZ₅ increased by 0.66, 0.33 and 1.53 compared with the control, and the number of buds and bolls increased by 8.68%, 17.23% and 23.45% compared with the control; Compared with the control, the weight of reproductive organs of TDZ₅ increased by 1.93%.Each treatment increased the single boll weight and yield of cotton, among which, TDZ₂ and TDZ₃ increased by 1.53 g and 1.28 g, and TDZ₁ and TDZ₃ increased by 31.82% and 29.50% compared with the control.The elongation of TDZ₃ was higher than that of the control by 1.04%.The number of fruit branches was significantly positively correlated with plant height, stem diameter and number of buds and bolls, the number of buds and bolls was significantly positively correlated with plant height and stem diameter, the number of buds and bolls per plant was positively correlated with stem diameter, number of buds and bolls per plant, and the yield was significantly positively correlated with the number of bolls per plant and single boll weight.【Conclusion】 Spraying 150g/hm² 0.1% thiabenduron and 150g/hm² 14 hydroxybrassinolate can increase the number of buds and bolls, the number of bolls per plant and the weight of bolls per plant, thus significantly improving the yield.

摘要：

【目的】 研究喷施0.1%噻苯隆复配不同外源物质对棉花生长发育和产量品质的调控效应。【方法】 于2021年在沙雅县海楼镇墩力买村进行田间试验,棉花品种为新陆中67号,以0.1%噻苯隆150 g/hm²为主,分别和14-羟基芸苔素甾醇150 g/hm²(TDZ₁)、复硝酚钠300 g/hm²(TDZ₂)、胺鲜酯150 g/hm²(TDZ₃),诱抗素300 g/hm²(TDZ₄)和乙烯利300 g/hm²(TDZ₅)进行复配,清水为对照(CK),采用随机区组设计,分析棉花打顶后喷施1次0.1%噻苯隆复配不同外源物质对棉花农艺性状,干物质积累与分配和产量品质的影响。【结果】 TDZ₁、TDZ₂和TDZ₅较对照果枝台数增加0.66、0.33和1.53台,较对照蕾铃数增加8.68%、17.23%和23.45%;TDZ₅较对照棉花生殖器官重量增加1.93%,各处理提高棉花单铃重和产量,其中TDZ₂和TDZ₃较对照单铃重增加1.53和1.28 g,TDZ₁和TDZ₃较对照产量增加31.82%和29.50%。TDZ₃的伸长率较高,较对照分别提高1.04%。果枝台数与株高、茎粗和蕾铃数呈显著正相关,蕾铃数与株高、茎粗果枝台数呈显著正相关,单铃重与茎粗、蕾铃数和单株结铃数呈正相关,产量与单株结铃数和单铃重呈显著正相关。【结论】 喷施150 g/hm² 0.1%噻苯隆和150 g/hm² 14-羟基芸苔素甾醇后可提高棉花蕾铃数,单株结铃数和单铃重从而显著提高产量。
