苹果对水分胁迫的反应特点及节水灌溉研究综述

Studies on the Reaction of Apple to Water Stress and Its Water saving Irrigation

干旱缺水是制约我国农业经济和农村社会持续、快速、健康发展的关键生态因子。因此 ,必须走节水而优质、高产、高效的现代农业产业路子。基于此一认识 ,综述了我国第一大果树——苹果科学灌溉的重要理论基础——对水分胁迫的反应特点及在需水非关键时期的节水灌溉问题 。

In China,especially in the northern area of the Yangtze River,scientific research and productive practice have proved that water shortage is the critical ecological factor limiting the sustainble,speedy,and healthy development of agricultural economy and rural society.Therefore,the principle of saving water while getting superior quality,high yield,and plentiful earnings must be followed.According to this recognition,the article reviewed the important base of scientific irrigation of apple orchard that reacts to water stress,including physiological and biological reaction,and water saving irrigation utilizing apple’s characteristics of reacting to water stress.In the end,the author pointed that extensive while intensive research and practice remain needed in order to make this technical system more perfect and practicable though the prospect of apple saving water irrigation is brilliant.
