摘要
本研究在分析江汉平原气候资源的基础上，改一年一熟为一季（棉花生长季）多熟种植，并分析了这种栽培模式的经济效益及其对改善棉花群体中下部光照分布的效应。由于农田小气候的改善，棉花蕾铃脱落率降低１２％，经济效益提高３９％。
The study on Basis of analyzing the climate resoures of Jiang Han plain modifed one-crop a year as many-crops a seeason(cotton growing sesson),and analyzed the economic benefit of this pattern the effect of the pattera to improve lightintensity distributed in the middle/lower cotton colony.Beacuse improving of farm-climate,the cotton buds and bolls falling off reate reduces l2%,economic benefit rises 39%.
