棉株现蕾后即从营养生长进入生殖生长,但仍是营养生长占优势,以增大营养体为主。这一阶段的田间管理重点是在壮苗早发的基础上,采取合理的促控措施,调节棉株地上部和地下部、营养生长和生殖生长的关系,实现发棵稳长。发棵是高产的基础,稳长是高产的保证。
After cotton buds grow into vegetative growth from vegetative growth, but still dominant vegetative growth, to increase the main nutrients. The key point of field management at this stage is to take reasonable measures to control and control the relationship between vegetative and reproductive growth of above-ground and underground parts of cotton plants, so as to achieve a stable growth on the basis of vigorous growth of young seedlings. Hair is the basis of high yield, long and stable yield is guaranteed.
