摘　　要：棉花良种产质量的形成除生态气候条件外与株型的关系十分密切。当前联产承包、讲究综合效益的情况下,中等密度逐渐取代过密过稀群体,中壮株型(高度适中、植株健壮、根系强盛)逐渐取代高大株型和矮小株型,经济施肥和适促适控逐渐取代大肥大水和多促多控,为大多数良种繁殖地区所接受,并充分显示良好的经济效果。本文就不同株型对棉种产量和品质的影响进行连续2年的研究,旨在探讨一定密度条件下不同株型农艺、经济性状的比较及其相关,最佳株型产量的合理结构,各生育阶段的发展动态,株型塑造的最佳选择等,为良种繁殖和优化株型提供科学依据。Upland cotton seed yield and quality are closed to plant shape besides ecolo-gical and climate conditions.In order to increase the efficieecy of cotton seed pro-duction,rational close planting,optmun plant shape and scientific culture wouldbe taken instead of high or low close planting,unnormal plant shape andover amount of fertilizer or over chemical control.The comparision of agronomicand economic traits,dynamic of growth and development in different stage withvarious plant shape and the structure of optimum plant shape were studied in thisexperiment during the period of two years.The results obtained from this paper willbe helpful for the improved cotton seed production.
