摘要
本文以提高作物光能利用率为目的,对光在棉花群体中的分布规律作了系统的研究,在研究的基础上提出了发展塑膜覆盖栽培技术,人工控制光能在棉田中分布的设想。
The study was focused on light distribution of cotton population for the purpose of raising so- lar energy utilization. An idea was developed that efforts should be made to apply plastic-film mulching to artificially control light distribution in cotton production.
