通过对马莲河流域世行贷款水土保持项目实施前后人工造林、种草成效的对比分析,认为“高效林草建设”是植被稀疏、地形支离破碎、水土流失严重的黄土高原沟壑区、黄土丘陵沟壑区植物措施治理的最佳途径.其主要措施有:按照“适地适树、适草”的原则,选择适应性强、速生丰产优质的树草(品)种,对位配置;积极推广ABT生根粉蘸根、吸水剂泡根、根宝浸根、径流林业、容器苗造林、营造乔灌混交林、浸水造林等实用造林技术;进行规范化育苗和精细整地,辅以家畜舍饲喂养,缓解林牧矛盾等.
By contrasting the results of artificial afforestation and planting before and after World Bank-financed Soil and Water Conservation projects in the Malian River Basin, it is concluded that the “high-efficiency forest and grass construction” is characterized by sparse vegetation, terrain fragmentation and severe soil erosion in the Loess Plateau gully region, The best way to control the measures.The main measures are: According to the “suitable tree, suitable for grass” principle, choose adaptive, fast-growing high-quality tree grass (products), the allocation of bits; actively promote ABT rooting powder Dipping roots, water-absorbing foam root, root Po root immersion, runoff forestry, container seedlings afforestation, to create a mixed plantation of algae and shrubs, soaking afforestation and other practical afforestation techniques; standardized nursery and fine preparation, supplemented by livestock feeding, Conflict and so on.
