在黄土丘陵沟壑区半阴坡立地上,采用正交设计进行抗旱造林综合措施分析。结果表明,采取整地、保水剂浸根和穴施菌根菌综合措施营造油松、刺槐和侧柏,虽然增加了造林成本,但造林成活率和苗木生根数量都明显高于对照。经济有效的综合措施为:造林树种为刺槐,鱼鳞坑整地,保水剂浸根(1.5g/穴),穴施菌根菌(1ml/穴)。
On the site of semi-shady slopes in the hilly and gully regions of the Loess Plateau, orthogonal design was used to analyze the comprehensive measures to combat drought and afforestation. The results showed that the integrated measures of soil preparation, root immersion and cavitation of mycorrhizal fungi to create Pinus tabulaeformis, Robinia pseudoacacia and Platycladus orientalis increased the afforestation cost, but the afforestation survival rate and seedling rooting number were significantly higher than those of the control. The economic and effective comprehensive measures are as follows: afforestation tree species are locust locust, fish scale pit site preparation, water retention agent root immersion (1.5g / hole), point application of mycorrhizal fungi (1ml / hole).
