在我省一般气候条件下,棉花生育后期是指花铃后期(8月上旬到8月下旬)大约25—30天的时间和正常吐絮期(8月下旬到10月下旬)约60—70天左右。棉花进入吐絮期,株高、果枝已基本定型,叶片由下而上逐渐衰老,进行光合作用的功能显著减弱。这时,即便再出现花蕾,由于霜期所限,大都不能吐絮。因此,棉花后期管理的重点,应放在花铃后期。秋桃的产量一般可占总产量的30％左右。间作棉花,或前期遭受自然灾害的棉花,由于发育较
In the general climatic conditions in our province, the late growth period of cotton refers to the time of about 25-30 days and the normal bolting period (from the end of August to the end of October) of about 60-70 days after the late flowering period (early August to late August) about. Cotton into the boll opening period, plant height, fruiting branch has been the basic shape, the leaves gradually aging from bottom to top, the function of photosynthesis significantly weakened. At this time, even if the buds appear again, due to the limitation of the frost period, most of them can not be opened. Therefore, the focus of late management of cotton should be placed in the late flower. Autumn peach production can generally account for about 30% of total output. Intercropping cotton, or pre-natural disaster of cotton, due to development
