摘 要:以人工种植梭梭为研究对象,采用工程集水沟和坡面集水沟2种地形整治方式,研究不同措施对梭梭生长和成活率的影响。结果表明,(1)粘土地梭梭造林种植穴换沙优于原状土回填;(2)工程集水沟和双坡面集水沟不同灌溉量下梭梭造林最优灌溉量均为60 L,工程集水沟梭梭造林优于双坡面造林;(3)应选择半径为25cm、深度为60 cm的种植穴进行梭梭造林;(4)粘土地种植穴换沙后添加保水剂抑制梭梭生长;(5)地形改造后梭梭造林成活率为89.4%。Based on Haloxylon ammodendron (C. A. Mey. ) Bunge plantation, the effect of different planting meas-ures on the growth and survival rate was studied. The results showed that : ( 1 ) Planting hole of 1t. ammodendron(C. A. Mey. ) Bunge for sand was better than undisturbed soil backfill in clay; (2) The optimal amount of irriga-tion was 60 L under engineering gullies and dual slope condition, and the engineering gullies planting was superiorto the dual slope planting; (3) The best radius of planting hole should be 25 cm, with a depth of 60 cm; (4) Put-ting SAP in planting hole after changing sand in sticky land could inhibit the growth of H. ammodendron( C. A. Mey. ) Bunge ; (5) The overall survival rate was 89.4 % after appropriate land terraforming.
