| 摘 要： | 通过对南疆干旱地区荒山绿化所采用的胡杨、沙枣、柽柳和白榆等4种主要造林树种在滴灌条件下的生长发育规律进行研究,结果表明:4种树木在滴灌条件下根系分布存在着明显差异;生长高峰期到达的时间不同,白榆生长高峰期最长,其次为沙枣、胡杨、柽柳;4种树木耐盐程度不同,柽柳耐盐性最强,在总盐含量2.26%的情况下,尚能生长。

| Abstract: | The growth law of 4 species of afforestation species under drip irrigation was studied in the drought areas of south part of Xinjiang. The results showed that under drip irrigation, the radication distributions of these 4 species of trees had significant differences. And the growth peak arrived at different time. While the Ulmus pumila had the longest growth peak then Elaeagnus angustifolia,Populus euphratica,and Tamarix chinensis in turn. The salt tolerance of these 4 species of trees were different and the Tamarix chinensis was the strongest of all. Even under total salt content at 2.26%, Tamarix chinensis still can grow. |
