Research on the Different Colonial Canopy Architecture Characters and Yield Characters of Machine Harvesting Cotton under Different Field Collocation Patterns
摘要
Abstract
[Objective] The aim of this paper is to study the impacts of different field collocation patterns on the colonial canopy architecture character and yield character of mechanical harvesting cotton.[Method] The colonial canopy architecture character and yield character under different field collocation patterns were analysed.[Result] The results show that different configurations have significant impact on leaf-area-index (LAI).For LAI of cotton,the high to low sequence is a film match two drip irrigation tapes,a film match three drip irrigation tapes,a film match four drip irrigation tapes and a film match five drip irrigation tapes at full-boll stage.The sequence of the leaf inclination angle is a film match three drip irrigation tapes ＞ a film match six drip irrigation tapes ＞ a film match five drip irrigation tapes ＞ a film match four drip irrigation tapes.There is significant difference between a film match four drip irrigation tapes and a film match six drip irrigation tapes at full flowering stage.The highest and the lowest degrees of DIFN are a film match five drip irrigation tapes and a film match six drip irrigation tapes respectively at full-boll stage.A film match six drip irrigation tapes could make full use of the population dominance and increase the cotton yield.[Conclusion] Plant configuration mode of A film match six drip irrigation tapes could raise light energy utilization ratio,improve canopy structure and photosynthesis and also greatly improve the yield.关键词
