【摘要】 经过３ａ的研究，摸清了高产棉田不同品种适宜的叶面积指数和叶片着生角度，光合速率与产量的关系，冠层分布及品种间的差异，外界条件对光合速率的影响以及水分、养分吸收特性，为棉花高产优质高效栽培技术提供了理论依据更多还原

【Abstract】 Through 3 years research, proper LAI , inserting angle of leaves, the raletionship between photosynthesis rate and yield conopy seructure and intervariety differences have been found out in various varieties of high yield cotton field. Effect of enviroment on the photosynthesis rate, characters of water, nutrition absorbing contribute to the theory basis of cotton high yield, quality cultivation.更多还原
