半个世纪以来,松嫩平原土地盐碱化发展迅速,严重影响农牧业的发展,虽然采取各种方法进行治理,但其效果不甚理想。作者采用俄罗斯黄花草木樨,对松嫩平原西部盐碱化土壤进行系列改良,取得了明显效果:pH值从9.1下降至8.6,碱化度下降15.18%,可溶盐总量下降10.11%,有机质总量提高13.58%,总氮量提高11.92%。土壤结构及物理性状也有较大的改善,土壤孔隙度增加了15.42%。改良后的土壤可以种植谷物和牧草,并获得较好的收成。农田、草地生态系统逐步得到恢复和重建。研究表明,种植黄花草木樨可获得较大的生态、经济和社会效益。因此,建议推广种植及开展综合利用,以保护土地资源,促进粮食安全。
For half a century, the salinization of Songnen Plain has developed rapidly, seriously affecting the development of agriculture and animal husbandry. Although various measures are taken to control it, the effect is not very satisfactory. The authors used the Russian yellow flowers clogs, the Songnen Plain in the western salinization of soil series improved, and achieved remarkable results: pH value decreased from 9.1 to 8.6, alkalinity decreased 15.18%, total soluble salt decreased 10.11%, organic matter Total increase of 13.58%, total nitrogen increased by 11.92%. Soil structure and physical properties also greatly improved, soil porosity increased by 15.42%. Improved soil can grow cereals and pastures and get better yields. Farmland and grassland ecosystems have been gradually restored and rebuilt. Studies have shown that the planting of Habitat yellow Clivia can get greater ecological, economic and social benefits. Therefore, it is recommended to promote planting and comprehensive utilization in order to protect land resources and promote food security.
