蒋家沟是我国西南山区一条典型的暴雨型泥石流沟 ,每年雨季爆发泥石流 1 2～ 2 0次以上 ,每年冲出沟口的固体物质总量平均达 1 0 0万m3～ 30 0万m3,给当地工农业生产造成严重经济损失。蒋家沟在内外营力作用下 ,生态环境严重恶化 ,泥石流等山地灾害日趋严重。拟金茅生态适应性强 ,能耐干旱瘠薄。在蒋家沟退化山地采用分株繁殖、种子直播和育苗移植等方式引种拟金茅试种成功。生长发育快 ,经济效益高 ,改善环境效果好 ,推广应用前景广阔
Jiangjiagou is a typical rainstorm-type debris flow ditch in the southwest mountainous area of China. Each year, 12 ~ 20 times of mudslides break out in the rainy season. The total amount of solid matter that fills the Mizoguchi reaches an average of 10 million m3 to 30 million m3 annually, To the local industrial and agricultural production caused serious economic losses. Under the action of the internal and external operations of Jiangjiagou, the ecological environment has deteriorated severely, and mountainous landslides such as debris flow have become increasingly serious. Pseudocus major ecological adaptability, drought tolerance barren. In Jiangjiagou degraded mountain, ramets were introduced by means of ramets propagation, seed direct seeding and seedling transplantation. Fast growth and development, high economic benefits, good environmental effect, and broad prospects for promotion and application
