不同配置方式对棉花冠层结构及产量的影响

在大田自然生态条件下,对目前生产上采用的三种配置方式下的冠层结构及与产量的关系进行研究.结果表明,在北疆特早熟棉区适期播种条件下,最适配置方式为小三膜.该配置方式下,棉花冠层结构及光合物质累积均优于其它群体,经济产量高.同时,提出适宜冠层结构的若干指标,为确定棉花高产栽培措施及建立棉花生产管理模型提供参考.

Effect of Plant Modes on Canopy Structure and Yield

The effects of different plant modes on canopy structure and yield were studied.The results indicated that the optimum plant modes is Xiaosanmo under the circumstances of cotton sowing timely of earlier harvest area of the North in Xinjiang.Based on the plant modes,cotton canopy structure and dry matter accumulate is better than other densities of the community,so lint yield is higher than the other densities.And some canopy structure indexes for high-yield cotton were proposed in this paper.The suggestion was made for effective cutivate meassures of high-yield cotton and better management models of cotton production.
