摘要
根据伊犁河流域重点开发区的立地条件,对防护林适宜树种进行试验栽培,并分析其防护效益;结果表明,从成活率、生长率、更新能力等多指标对比观察分析,钻天榆等10个树种苗木生长旺盛,根系发达,成活率高,适应性强,可作为造林首选树种;由适宜树种构建乔灌草窄带多带式农田防护林体系,不仅起到了良好的农田防护效益,还兼顾了经济效益和社会效益,可进行大面积推广应用。
According to the key development zone＇ s condition for water and soil of Yili river basin, suitable trees were selected to build protective forest, and their benefits were analyzed. The result indicated that from the survival rate, the growth rate, from observation analysis, drilling days elm and others nine trees can be preferred planting native trees because their developed roots, the survival rate was high and compatible.
