| 摘 要： | 以JX013为材料，在湖南浏阳研究了不同种植密度（18000、36000、54000株/hm2）、不同种植方式（直播、漂浮育苗移栽、营养钵育苗移栽）对棉花生长发育及产量、品质的影响。结果表明：在同一种植方式中，生育期随密度的增加而延长，株高、果枝数、单株成铃数随密度增高而降低，单位面积总铃数、籽棉产量随密度增高而增加；在同一密度下，生育期以直播棉最短，株高、果枝数、单位面积总铃数、籽棉产量以直播棉最大；不同处理对棉花铃重、衣分、衣指、子指、纤维品质影响不显著。

| Abstract: | Effects of different planting densities,18 000,36 000 and 54 000 plants/hm2 ,and different planting patterns,di-rect seeding,floating seedling ＋transplanting and nutrition pot seedling ＋transplanting,on growth and development, yield and quality of cotton were studied with JX013 as material in Liuyang,Hunan. The results indicated that：under the same planting pattern,with the increment of density,growth duration was prolonged,plant height,fruit branch number and number of bolls per plant were decreased,while total number of bolls and yield of seed cotton in unit area were increased.Under the same density,growth duration of direct seeding cotton was shortest,plant height,fruit branch number,total num-ber of bolls and yield of seed cotton in unit area of direct seeding cotton were highest. Effects of different treatments on boll weight,lint percentage,lint index,seed index and fiber quality were not significant. |
