通过1993～1994年在盐渍土壤上引种栽培耐盐牧草———高冰草的试验后,探讨了高冰草干旱区的栽培技术、改良盐渍土的效果、提高碱地生产力获得了良好的效果。试验结果表明,在耕作层含盐量不高,尤其是pH8.5的低肥力土壤上,高冰草能正常出苗,生长发育良好,产草量较高。播种以后第2年取土样进行分析,分析结果表明,pH值明显下降,土壤物理性质也得到了好转。
After the experiment of introducing salt-tolerant grasses --- GaoBingcao on saline soils from 1993 to 1994, the cultivation techniques of the GaoBingcao arid areas, the effect of improving the saline soils and the improvement of alkali productivity were obtained Effect. The results showed that, in the tillage layer is not high salt content, especially in low-fertility soil pH8.5, tall grass can normally emerge, grow well, high yield. In the second year after sowing, the soil samples were taken for analysis. The results showed that the pH decreased obviously and the physical properties of the soil also got better.
