摘要：

比较五种不同种植方式棉花的干物质积累的全过程,发现早育套栽和麦后移栽的处理间差异不大,初花前的积累量占总干物质积累量的15.15～19.24%,初花后占80.76～84.85%。但早育套栽的早棉花,其前期(初花前)积累量反而略低于迟播栽的积累量,后期(盛花后)则远远高于迟播栽的棉花。生殖器官所占的干物质比率也高于迟棉花,所以早棉花的总积累量高,经济产量系数也较高,这是早播棉花的生理基础。五种不同种植方式棉花的干物质总积累量与温度、日照和雨量均呈显著的正相关,但从开花到吐絮的积累量与雨量呈负相关,就三个气候因素与干物质积累的相关程度而言,主要是温度和日照,其次是雨量。这三个气候因素对干物质积累的影响时期,主要在开花到吐絮。
