分别于2009年、2010年春季,在新疆古尔班通古特沙漠南缘选取了迎风坡、丘间平地、背风坡作为研究样地,采用不同的技术措施(保水剂、生根粉和液体地膜)进行梭梭免灌造林试验,以确定这些技术措施是否能有效提高古尔班通古特沙漠地区免灌造林成活率。结果表明:实施这些措施后,不同立地条件之间梭梭免灌造林成活率存在显著差异;水分是限制古尔班通古特沙漠梭梭免灌造林成活的关键因子,土壤理化性质对梭梭免灌造林成活率影响不显著;三种造林措施对梭梭免灌造林成活率有一定作用,但效果不显著。
In the spring of 2009 and the spring of 2010, windward slope, mound flatland and leeward slope were selected as the study sites in the southern margin of the Gurbantunggut Desert in Xinjiang. Different technical measures (water-retaining agent, rooting powder and liquid film ) To carry out Haloxylon amylin-free trials to determine whether these technical measures can effectively improve the survival rate of irrigation-free forests in the Gurbantunggut Desert. The results showed that there was a significant difference in the survival rate of Haloxylon ammodendron after different measures of site conditions. Moisture content was the key factor limiting the survival of Haloxylon ammodendron community in Gurbantunggut Desert. The physical and chemical properties of Haloxylon ammodendron There was no significant effect on the survival rate of non-irrigated forest. The three afforestation measures had some effect on the survival rate of Haloxylon ammodendron without irrigation, but the effect was not significant.
