为了治理松嫩平原盐碱化草地,试验采用引进的20种多年生禾本科牧草建植人工草地,进而筛选适合松嫩平原生态环境的禾本科牧草品种,测定牧草的物候期、植株高度、密度、产草量和越冬率等。结果表明:野大麦、农菁4号羊草、东北羊草抗盐碱性强,适宜在松嫩平原盐碱化草地大量推广种植。说明选择适宜草种是人工草地建植成功的关键因素。 In order to control the salinized grassland in the Songnen Plain, the artificial grassland was planted with 20 perennial grasses imported from the Songnen Plain, and the grasses suitable for the ecological environment of the Songnen Plain were screened. The phenophase, plant height, density, Yields and overwintering rates. The results showed that wild barley, Nongjing 4 and Leymus chinensisweed had strong resistance to salinity and alkalinity, and were suitable for extensive planting in salinized grassland of the Songnen Plain. This indicated that the selection of suitable grass was the key factor for the success of artificial grassland construction.
