摘　　要：以山西省太宽河国家级自然保护区山杏和油松为研究对象,在水平沟和V型坑2种整地方式下,采用3种单一保水保湿技术及4种综合保水保湿技术进行造林试验,分析了不同造林技术对造林地土壤含水量及对幼苗生长情况的影响。研究结果表明,水平沟整地和V型坑整地对造林地土壤含水量的影响不大,但不同保水保湿技术均可有效提高造林地土壤含水量。从造林效果来看,水平沟和V形坑整地对山杏和油松造林成活率及苗木生长情况的影响相差不大。从不同集水造林技术来看,覆盖防草布是保证造林成活率和苗木生长的关键技术。综合比较来看,覆盖防草布(A)+膨润土(B)+黄腐酸(C)效果最好,其次是覆盖防草布(A)+膨润土(B)或覆盖防草布(A)+黄腐酸(C)。The Prunus sibirica and Pinus tabuliformis in the Taikuanhe National Nature Reserve in Shanxi Province were studied.Afforestation experiments were conducted using 3 single water-harvesting techniques and 4 comprehensive waterharvesting techniques under horizontal ditch and V-shaped pit 2 land preparation methods.The effects of different waterharvesting techniques on soil moisture content and seedling growth in the afforestation area were analyzed.The research results indicated that there was not much difference in the impact of horizontal ditch and V-shaped pit land preparation methods on soil moisture content in afforestation sites,but different water-harvesting techniques could effectively improve the soil moisture content of afforestation.The horizontal ditch and V-shaped pit land preparation methods had little effect on the survival rate and seedling growth of Prunus sibirica and Pinus tabuliformis.From the perspective of different wate-harvesting techniques,covering with grass proof cloth was the key to ensuring the survival rate of afforestation and the growth of seedlings.Overall,covering with grass proof cloth(A)+bentonite(B)+humic acid(C)had better effects,followed by covering with grass proof cloth(A)+bentonite(B)or grass proof cloth(A)+humic acid(C).
