摘要
主要探讨了计算旱作沟垄地膜覆盖农田气候工程集水率的简便方法,定量评价这种农田耕作方式的集水效应和生产经济效益,为广大干旱半干旱地区的沟垄覆盖农田提供理论依据和作业设计方法。
This paper is to discuss a simple method to calculate the water collection efficiencyof farmland climate engineering through ridge and furrow plastic sheet multching in dry-land farming.Also,it quantitatively evaluates the water collection effects of this cultiva-tion pattern and economic effects of production,thus providing the theoretical base andoperational design method of ridge and furrow multching cultivation in the broad aridand semiarid areas.
