沙枣耐盐碱、耐干旱、耐贫瘠,繁殖,生长迅速,是塔里木河两岸盐碱地区营造防护林、薪炭林和改良土壤的主要树种之一。但是,近年来有一种木虱害虫,偏嗜沙枣,一九七一年以前危害尚轻,以后逐渐蔓延,致使沙枣树100％被害,每叶有虫50—60头至百余头,被害叶片背面卷曲皱缩,黄化凋萎(仍固着在枝条上),被害嫩枝变为臃肿、扭曲和萎缩,有的整枝整枝枯死。 The jujube is one of the major tree species for shelterbelts, firewood forests and soil improvement in the saline-alkali areas along both sides of the Tarim River due to its resistance to salt and alkali, drought resistance, poor resistance to infertility, and rapid growth. However, in recent years, there is a kind of insecticide that is insensitive to jujube. Before 1981, the harm was still slight and then spread gradually. As a result, 100% of the jujube tree was killed, Crimson leaves on the back crimp shrink, yellow wilting (still fixed in the branches), the victim of the tender become bloated, twisted and atrophy, and some pruning twigs dead.
