内蒙古内陆盐碱荒地及因盐碱危害形成的弃耕地分布广泛,选择种植耐盐碱性较强的牧草品种是利用改良这部分土地资源的有效途径。经设点试验研究,沙打旺是较适宜的豆科牧草,过去以耐旱、耐瘠著称,通过具体实践而是有一定的耐盐碱性。我们在土默川平原,盐碱荒地,无灌溉条件下,已较大面积旱植沙打旺成功,取得了显著经济效益,社会效益和生态效益。 Inland saline-alkali wasteland in Inner Mongolia and abandoned farmland due to the damage caused by saline-alkali are widely distributed, and choosing to cultivate pasture varieties with high salinity and alkalinity is an effective way to utilize this part of land resources. Through the experimental set-point study, Astragalus adsurgens is more appropriate leguminous pasture known to drought, barren known by specific practice but have a certain degree of salinity. In the Tumochuan plain, saline-alkali wasteland and non-irrigated area, we have succeeded in large-scale dry land and planted with sand and achieved remarkable economic, social and ecological benefits.
