1984—1989年,山西省朔州市山阴县农业开发公司。林业局等单位,先后在县二苗圃、合盛堡乡杨庄、大虫堡等重盐碱荒滩上试种芨芨草。经过多年的育苗、移栽、管理等科学试验,终于获得成功。试种面积从几十亩、几百亩扩大到4400多亩,成活率平均80％以上。人们多年的愿望“荒滩变绿洲”已成为现实。一、改碱途径山阴县位于洪涛山下雁门关外、桑干河畔大同盆地的西南部。由于地势平坦低凹,地面水、地下水大量汇积,排水出路不好,地下水位抬高,超过临界深度。气候干旱,年蒸发量(2024.6毫米)大于年降水量(397.3毫米),特别是春季蒸发量是降雨
1984-1989, Shanyin County, Shanxi Province Agricultural Development Company. Forestry Bureau and other units, successively in the county two nurseries, a village Sheng Yang Zhuang, a large insects and other heavy saline on the saline wasteland trial Tricholoma. After years of nursery, transplanting, management and other scientific experiments, finally succeeded. Test area from dozens of acres, a few hundred acres expanded to 4400 acres, an average survival rate of 80% or more. Years of people’s desire “deserted oasis” has become a reality. First, the way to change the base of Shanyin County is located under the Hongtao Yanmen off the Sanggan River Datong Basin in the southwest. Due to the flat depression, surface water, a large accumulation of groundwater, drainage outlet is not good, raise the groundwater table, exceeding the critical depth. The climate is arid, with annual evaporation (2024.6 mm) greater than annual precipitation (397.3 mm), especially with spring rainfall
