| 摘 要： | 为探讨抗旱造林粉、BGA激活剂、ABT生根粉和浸根造林等抗旱技术对梭梭造林的影响,在民勤干旱沙区开展了有关应用技术研究.结果表明：（1）不同抗旱造林技术处理对造林林分保水作用存在一定的差异,BGA土壤激活剂使梭梭造林林分（100 cm）土壤含水率提高53.24％;（2）抗旱造林技术对梭梭的生长差异显著,BGA土壤激活剂处理的梭梭植株高相对对照处理增长5.32 cm,枝长增长2.81 cm; （3）抗旱造林技术对于提高梭梭造林成活率有促进作用.ABT生根粉、抗旱造林粉2种处理对于对照处理成活率分别提高8个百分点和6个百分点.

| Abstract: | Four kinds of techniques of drought resistance were in Minqin desert area to probe into theirs effects on water saving and applied in Halaxylon ammodendron afforestation plant growth. The results indicated that different techniques of drought resistance had certain difference on the effect of water saving. Average soil moisture content of forestland of H. ammodendron of 100 cm deep being treated by BGA activator increased by 53.24%. Different tech- niques of drought resistance had significant difference on the effect of plant growth. Compared to control treatment, the tree height and branch length of H. ammodendron being treated by BGA activator increased by 5.32 cm and 2.81 cm. Survival rate of H. ammodendron that were treated by different techniques of drought resistance could be improved. Compared to control treatment, the survival rate of H. ammodendron being treated by ABT rooting powder and drought affroestation powder increased by 8% and 6%. |
