摘　　要：高效的水肥管理是实现干热河谷牛油果优质高产的主要技术。该文概述了牛油果植物学特征,分析了牛油果对大、中、微量营养元素的需求特性、耐盐特性和水分需求特性,指出牛油果全年可生长,根系脆弱,需要大量的钙养分供应,其灌溉设计的作物参数应取值在0.6~0.8。Efficient water and fertilizer management technology is the main technical means to achieve high quality and high yield of avocado in dry-hot valley.On the basis of summarizing the botanical characteristics of avocado,this paper summarized the demand characteristics of large,medium and tiny nutrients,salt tolerance characteristics and water demand characteristics of avocado.The results showed that the annual growth of avocado did not stop,and its root system was fragile,which required a lot of calcium supply.Meanwhile,the crop parameters for irrigation design should be between 0.6 and 0.8.
