经六年的试验建设,以网、带、伞、疏、片为格局的3万亩草牧场防护林体系已初见规模。为生产示范和进一步开展综合效益研究提供了基地,建立了面积为2000亩的草原立体开发试验示范区。林草、林药(草)、林粮、林果结合初见成效,为草原开发利用和草原生态建设提供了新的途径。选择出半干旱沙地草牧场防护林体系建设的理想树种一樟子松。樟子松抗旱造林新工艺和开沟抗旱造林的技术措施,在半干旱地区实用可行,对提高造林质量、加快“三北”防护林体系建设有重要意义。
After six years of trial construction, the system of shelterbelt with a land area of 30000 mu of grassland, net, belt, umbrella, sparse, and film has seen initial scale. It provided a base for production demonstration and further comprehensive benefit research, and established an area of 2000 mu grassland three-dimensional development pilot demonstration area. Forest grass, forest medicine (grass), forest grain, fruit combined with initial results, for the development and utilization of grassland and grassland ecological construction provides a new way. Select the ideal semi-arid sand grassland pasture shelter system construction of a Scotch Pine. Pinus sylvestris drought-resistant afforestation new technology and ditching drought-resistant afforestation technical measures, practical and feasible in semi-arid areas, to improve the quality of afforestation, accelerate the “Three North” shelterbelt system construction is of great significance.
