沙枣耐干旱,耐盐碱,抗风沙,根系生瘤,能固氮增加土壤养分,繁殖容易,适应性强,经济价值较高,是干旱,土壤盐渍化较重,排水条件差的地区极易生长的造林树种,为新疆荒漠平原地区群众所喜爱。近年来,在南疆阿拉尔地区发现过去罕见的沙枣蓝跳(虫甲)(Alticasp)为害沙枣十分严重,幼芽、新梢、叶片被害后,树势衰弱,叶片枯焦早落,已经成为沙枣树重要害虫,引起了人们的关注。为摸清沙枣蓝跳(虫甲)生物学特性及发生规律,探索防治方法,笔者于1983—1984年经过两年的实地观察和饲养,现将结果总结于后:
The jujube is resistant to drought, salt-tolerant, wind-blown sand and root-knot neoplasms. It can increase the soil nutrient by nitrogen fixation, and has the advantages of easy propagation, strong adaptability and high economic value. It is a regional pole with drought, heavy soil salinization and poor drainage conditions Easy to grow afforestation species, loved by the people in the desert plains of Xinjiang. In recent years, in the Alar region of the South China Sea, it was found that the rare jujube (Alticasp) harm sand jujube is extremely serious. After the young buds, shoots and leaves are harmed, Become important sand pest jujube, has aroused people’s attention. In order to find out the biological characteristics and occurrence rules of S.japonica, and explore the methods of prevention and treatment, the author observed and reared two years in 1983-1984 and summarized the results in the following:
