一、棉花蕾期的生育特点和管理目标是什么? 棉花从开始现蕾至第一朵花开为止,这一生长发育阶段叫蕾期。地膜棉的蕾期一般始于5月下旬至6月下旬,约一个月左右。 蕾期是棉花由营养生长走向营养生长与生殖生长并进的第一个阶段,也是棉花生殖生长由弱到强、由小到大,迅速发展的阶段。这一阶段棉花一方面要进行旺盛的营养生长,搭好丰产的架子,另一方面也是大量形成有效的生殖器官的重要阶段。
First, cotton budding characteristics of the birth and management objectives? Cotton buds from the beginning until the first flower bloom, the growth stage is called the bud stage. Cotton buds generally begin in buds in late May to late June, about a month or so. Bud stage is the first stage of cotton moving from vegetative growth to vegetative and reproductive growth. It is also the phase of cotton reproductive growth from weak to strong, from small to large and rapid development. At this stage, cotton, on the one hand, needs vigorous vegetative growth, a high-yield shelf, and on the other hand, an important phase of massive formation of an effective reproductive organ.
