摘要: 【目的】研究棉花1膜3行种植模式下,密度与缩节胺用量对棉花生长发育及产量的影响及互作效应,分析此模式下棉花植密度和缩节胺优化组合,为该技术在生产上推广应用提供依据。【方法】棉花1模3行模式下,采用裂区设计,密度为主处理,设置3个水平,分别为9.4×104 、14.1×104和18.8×104株/hm2;缩节胺用量为副处理,也设置3个水平,90、180和270 g/hm2,研究两因素作用下,棉花生长发育及产量的变化。【结果】株高与密度呈正相关,而与缩节胺的用量呈负相关;棉株茎粗与密度呈负相关,与缩节胺的用量呈正相关;籽棉产量随密度与缩节胺用量的增加呈先增后减趋势。【结论】棉花种植密度在14.1×104株/hm2,缩节胺180 g/hm2时,最有利于棉花的生长发育及产量的形成。

Abstract: 【Objective】 Our objectives are to find out the optimal combination of cotton planting density and mepiquat-chloride application rate under the cotton planting mode of one film with three rows and provide theoretical support for its application in production by studying the corresponding effects on growth, development and yield of cotton. 【Method】 A split-plot field experiment was carried out with three densities in the main plots (94,000;141,000;188,000 plants/hm2) and three mepiquat-chloride application rates in the subplots (90,180 and 270 g/hm2). 【Result】 The results showed that plant height was positively correlated with plant density and negatively correlated with the application rate of mepiquat-chloride. In addition, a negative correlation was found between stem diameter and density, while positive correlation was found between stem diameter and the application rate of mepiquat-chloride. Seed cotton yield increased first and then decreased with the increase of density and application rate of mepiquat-chloride. 【Conclusion】 The results showed that cotton planting density of 141,000 plants/hm2 and DPC 180 g/hm2 were the most favorable for the growth and production of cotton.
