摘　　要：中国棉花栽培以精耕细作著称于世,去除叶枝则是精耕细作的重要技术内容。此文简述了保留营养枝对棉花生长发育、产量和纤维品质的影响,认为留叶枝能增大棉花的"源"与"库",促进根系与棉株的生长,壮大营养体,提高前中期的叶面积系数,对克服抗虫棉苗期生长慢等问题意义重大。在适当的栽培管理措施下,保留利用营养枝有利于促进棉花生产。近年来,作为棉花简化栽培技术之一的留叶枝栽培研究取得了明显的进展。Chinese cotton production is known to the world by intensive cultivation.Plant pruning is an important technology of intensive cultivation.Herein,progress in growth,yield and fiber quality application of cotton retaining of vegetative branches is introduced.We propose that retaining vegetative branches can increase the ＂source＂ and ＂sink＂ to promote the growth of root and the whole plant,vegetative growth,increase leaf area index before the middle.It ＇ s of great significance in overcoming slow seedling growth of cotton and other issues.With certain cultivation and management practices,the use of leafy shoots will have a positive impact on cotton production.In recent years,retention of leafy shoots which is one of the cost-saving cotton production systems has made significant progress.
