摘　　要：通过对不同种植方式下棉花生长发育和产量的分析,结果表明:油后直播在整个生育期的生长发育一直比其它种植方式缓慢,产量也最低;油后基质育苗移栽前期的生长发育缓慢,虽然后期逐步赶上,但产量仍然不是很高;油后营养钵育苗移栽在前期生长发育仅次于油棉营养钵育苗套栽,且在后期表现了良好的生长发育劲头,晚秋桃相对较多,产量最高;油棉营养钵育苗套栽在生育前期一直处于领先优势,但到后期这种优势逐渐减弱,导致其最终的产量并不是最高。Analysis of cotton growth and yield under different planting patterns, the results show that： growth and development of direct seeding after rape has been slower than other planting patterns in the whole growth period,yield is the lowest;Growth and development is slow at the early stage of seedling raising with soilless-substrate and transplanting after rape,although the latter have been catching up,but the yield is still not very high;Growth of interplant seedling raising and transplanting with nutritive soil-cubes cotton with rape has been in a leading edge at the early stage,but this advantage wears off at the latter,leading to the final yield is not the highest;Seedling raising and transplanting with nutritive soil-cubes after rape is second only to interplant seedling raising and transplanting with nutritive soil-cubes cotton with rape in the early growth and development,and has a good growth momentum in the latter part,the late autumn bolls are more,the yield is the highest.
