干旱地区开展节水造林技术的研究十分重要。研究结果表明，覆盖地膜使土壤含水率高于对照约２．６个百分点，５～１５ｃｍ土层中除１４时前后地温低于对照０．５３～３．９１℃外，其它时间均高于对照０．１～２．０８℃，２０ｃｍ土层覆盖薄膜地温高于对照０．１２～１．２２℃。十二种抗旱节水处理方法，旱地龙效果最为明显；铺膜以中膜（７０ｃｍ×７０ｃｎ）较为合适，吸水剂只要使用正确，对提高苗木成活率效果亦很显著
Arid areas to carry out water-saving afforestation technology is very important. The results showed that the soil moisture content was increased by about 2.6 percentage points compared with the control. The soil temperature in 5 ~ 15cm soil layer was lower than that of the control at 0.53 ~ 3.91 ℃ The soil temperature of 0.1-20.8 ℃ and 20cm soil cover film was higher than the control 0.12-1.22 ℃. Twelve kinds of drought-resistant and water-saving treatment methods, the effect of dry land dragon most obvious; membrane in the film (70cm × 70cn) is more appropriate, as long as the use of water-absorbing agent correctly, to improve the survival rate of seedlings effect is also significant
