摘　　要：通过试验对覆膜造林的抗旱效果进行了研究,结果表明：覆膜对土壤起到了明显的保水作用,覆膜造林区各层土壤含水量较对照区均有显著提高;覆膜造林地的地温较对照均有提高,日地温均值比对照区提高0.7-1.6℃;覆膜区域出苗时间相较于对照区缩短3d,成活率提高了54.5%,苗高生长量提高了149%,地径生长量提高了108%。The drought-resistant effects of film-covering afforestation were studied.Result shows that film-covering plays a significant protective effect on soil moisture.Moisture content of soil layers in film-covering afforestation region increase significantly than that of the CK.The ground temperatures in film-covering afforestation area all increase than that of the CK.The mean daily temperature increase by 0.7-1.6℃ than that of the CK.The emergence time in film-covering afforestation region shorten 3dthan that of CK.The survival rate,height growth diameter growth in film-covering afforestation region increase by 54.5%,149% 108%than that of the CK.
