摘 要:在干旱、半干旱条件下,以油松、柴松为供试树种,通过对等技术进行不同组合的配套,比较了不同抗旱措施对造林树种成活率、生长量的影响。结果表明:不同抗旱措施效果间存在差异,保水剂、控水袋及渗水膜三者共同应用后,对2种树种成活率、平均树高和当年新枝生长量的影响均比其他2种或1种措施的效果明显,能够有效提高造林成活率,促进生长。In the arid and semi-arid conditions, differences existed in the performance between the applications of integrated and single technique aided afforestation. Pinus tabulaeformis and P. tabulae forrnis f. sekannesis were selected as the test species, influences of different drought resistance techniques on the survival rates, and growth were investigated. The integrated technique of applying water retaining agent + plastic water controlling bag+permeable membrane exhibited more significant performance than that of applying single technique in seedling survival rate, seedling growing height, and the growth of the new twigs of the seedlings.
