指出了河西地区现有农田防护林体系存在着林带走向、林带间距不合理 ,林网配置树种单一 ,防护效益低下 ,全面抵御自然灾害的能力较差等问题。提出了合理进行更新采伐 ,加大保护力度 ;选择多树种混交的营造模式 ,提高林网抗御病虫为害能力 ;采用优质壮苗造林 ,ABT生根粉、多功能保水剂蘸根等方法提高造林质量等对策 It is pointed out that the existing farmland shelterbelt system in Hexi Region has such problems as the direction of forest belts, unreasonable spacing of forest belts, single distribution of tree species in the forest network, low protection benefit, and poor overall ability to resist natural disasters. The paper proposed a reasonable way of updating logging and intensifying the protection; choosing the mode of multi-species mixed planting to improve the capacity of forest network to resist pests and diseases; using high-quality seedling afforestation, ABT rooting powder, multi-functional water-retaining agent dipping root to improve afforestation quality Other measures
