摘　　要：对沙枣树的出胶进行了不同土壤水环境条件下的比较。结果表明,湿润林带的出胶率低,但出胶量高,干旱林带则相反,是出胶率高而出胶量低。沙枣树的出胶应该是自身生理活性作用和受害反应的结果。同时还发现沙枣树的出胶率和出胶量都随气温的增加而明显增加。指出出胶率高是病虫害侵染所造成,而出胶量高则是生理活性强的表现。沙枣胶的生产应该在新疆炎热的南疆地区进行,加强林带的管理和复壮有利于提高沙枣树的产胶量。In this paper, we compare the gum exudation of Elaeagnus angustifolia in different soil water environments. Its showed that the ratio of gum exudation in higher soil moisture environment is lower but its quantity of gum exudation is higher. As for arid environment the ratio of gum exudation in higher soil moisture environment is higher but its quantity of gum exudation is lower. The gum exudation of Elaeagnus angustifolia should be the consequence of physiologicl activity and reaction of infection. Meanwhile, it is discovered that the ratio and the quantity of gum exudation will increase sharply with the temperature increasing; the higher ratio of gum exudation is due to infection, while the higher quantity is due to intensive physiological activity. In Xinjiang, the production of gum of Elaeagnus angustifolia should be carried out in the hot south, besides, to reinforce the management of plantation and promote the growth of Elaeagnus angustifolia are helpful to enhance the quantity of gum exudation of Elaeagnus angustifolia.
