密度对长绒棉新海14的蕾铃脱落影响较大,随着密度的增加蕾铃脱落率增高,并且铃的脱落显著大于蕾的脱落;不同密度间蕾的脱落峰期均在花期,铃的脱落峰期均在盛花期;密度对蕾脱落的日龄影响较大,对铃脱落的日龄幅度影响不大;阿拉尔垦区适宜的种植密度为27万株/hm~2左右。
The density had a significant impact on the shedding of the buds of the new sea 14 of the long staple cotton. With the increase of the density, the shedding rate of the buds increased, and the shedding of the bolls was significantly greater than that of the buds. The shedding peak of buds with different density was at flowering stage, The peak of shedding was at full flowering stage. The density had a great influence on the days of bud shedding, but had little effect on the days of bell shedding. The suitable planting density of Alar reclamation area was about 270,000 plants per hectare.
