摘　　要：负压灌溉是利用压力差控制土壤含水量处于相对稳定的一种灌溉技术,它与传统灌溉明显不同。本文详细综述了负压灌溉条件下不同类型土壤含水量的变化情况,负压灌溉对不同作物水分利用效率、生理特性、养分吸收与利用、生长发育的影响,并且就负压灌溉对作物生长研究进行了展望。这为实现农业生产水分高效利用提供参考。The negative pressure irrigation is an irrigation technique that uses pressure difference to control soil moisture content in a relatively stable state,which is significantly different from traditional irrigation.This article provides a detailed overview of the changes in soil moisture content under negative pressure irrigation conditions,as well as the effects of negative pressure irrigation on water use efficiency,physiological characteristics,nutrient absorption and utilization,and growth and development of different crops.It also provides prospects for research on negative pressure irrigation on crop growth.This provides a reference for achieving efficient water use in agricultural production.
