系统地阐述了棉花生产中提高产量、品质和效益的关键技术措施。棉花育苗移栽已成为延长棉花有效生育期、提高复种指数、节省用种、提高种子利用率的有效途径。特别是近几年在抗虫杂交棉制种工作中,已成为提高棉花单产的重要措施。本试验目的是通过不同钵体大小及盖膜与否对棉苗质量、缓苗时间对棉花生育进程及产量的影响,探讨棉花育苗移栽改进措施,为进一步创高产提供理论依据。
Systematically expounded the key technical measures to increase the output, quality and benefit in cotton production. Transplantation of cotton seedling has become an effective way to extend the effective growth period of cotton, increase the multiple cropping index, save seeds and increase the utilization rate of seeds. In recent years, especially in the work of insect-resistant hybrid cotton seed production, cotton has become an important measure to improve yield. The purpose of this experiment is to discuss the influence of cotton seedling quality and Huanmiao time on the growth and yield of cotton through the different size of the bowl and whether the cover film or not, to explore the improvement measures of cotton seedling transplanting, to provide a theoretical basis for further high yield.
