摘　　要：探讨陆地棉宿生栽培的生长发育规律,为陆地棉宿生栽培提供理论依据。采用随机区组设计,以4个陆地棉品种为供试材料,以一年生陆地棉为对照,对二年生、三年生宿生陆地棉的生长发育规律进行研究。结果表明,宿生棉与一年生棉比较,生长量明显增大,现蕾、开花和吐絮期大幅提前,在一年内出现2次生长发育过程,单铃重和子指出现"低-高-低"、衣分出现"高-低-高-低"的动态变化。The perennial cultivation of annual cotton was very important for maintaining genic male sterile lines,producing hybrid seeds,fixing heterosis and preserving special germ plasm.The economic characters of perennial cultivation of annual upland cotton was researched to supply the theory of perennial cultivation.Random block design and orthogonal arrays were set up to investigate the yield and quality characters of triennial and biennial cultivation of annual upland cotton among 4 varieties of upland cotton,with annual cultivation as contrast,in Nanning Guangxi from 2005 to 2007.Compared with annual cotton,the plant size of perennial cultivation of upland cotton increased obviously,The dates of budding,flowering,spitting-wadding of perennial cultivation cotton are greatly ahead of the annual cotton.,second growth and development process appeared yearly.The boll weight and seed index of perennial upland cotton were changing from lower to higher,and then to lower,allowing the process of growth and development.And the lint percentage of perennial upland cotton were changing from higher to lower and then from higher to lower.Perennial cultivation of annual upland cotton caused its law of growth and development changing obviously.
