调亏灌溉对作物生理生态特征影响的研究进展
Research advance of effects of regulated deficit irrigation on physiological and ecological characteristics of crops
【摘要】 文章介绍了国内、外近年来调亏灌溉技术在农业生产中的应用及其作物的生理、生态反应和调亏灌溉的节水机理。探讨了调亏时期、程度、方式等条件对作物补偿效应的影响 ,指出了实施适度水分亏缺灌溉的可行性及风险性 ,为寻求更好的节水技术提供了科学依据
【Abstract】 The essay expatiates the internal and oversea application of regulated deficit irrigation(RDI) in the agricultural production recent years.And it also introduces the physiological and ecological effects for crops and the mechanism of saving water.By discussing the effects for crops and the mechanism of saving water.By discussing the effects of period,degree and method of RDI for compensatory effect of crops,it shows the feasibility and risk of temperate water deficit irrigation,and provides scientific reference for looking for better saving water technology.
