本文对春播棉、麦棉两熟制春套棉、晚春套棉及夏套棉四种不同耕作栽培途径棉田土壤水分消长动态进行了比较研究。阐明了不同耕作栽培途径棉田土壤水分垂直分布特征和在棉花不同发育时期土壤水分的消长动态,以期为不同耕作栽培途径棉田土壤水分管理和灌溉决策提供科学依据。
In this paper, the dynamic changes of soil moisture in cotton fields under spring tillage, wheat-wheat two-cropping cotton, late spring cotton-paddy and summer cotton-padded cotton were compared. The vertical distribution characteristics of soil moisture in different tillage and cultivation ways and the dynamics of soil moisture in different cotton development stages were clarified to provide a scientific basis for soil water management and irrigation decision-making in different tillage and cultivation ways.
