3a定位试验研究表明,艹律草群落不仅是一种优良的牧草资源,也是保土固土能力特别强的水土保持草本植物,是绿化荒山、荒坡、荒沟,改善黄土高原生态环境的一种理想草被;播种当年地面覆盖度可达80%,第2a可达90%以上;综合分析计算结果表明,与天然草被相比,艹律草配置简易水保工程措施的蓄水效益为46%,减沙效益为75.9%。
3a Pilot study showed that the herbaceous plant community is not only an excellent forage resource, but also a soil and water conservation herbaceous plant capable of retaining soil and retaining soil. It is a green barren mountain, a barren slope and a wasteland, and one of improving the ecological environment in the Loess Plateau The ideal grass is planted; the coverage of the year can reach up to 80% and the first 2a can reach more than 90%; The comprehensive analysis and calculation results show that compared with the natural grass, the water storage efficiency of the simple grass- 46%, benefit of sediment reduction was 75.9%.
