1 高山曼甸特点:多为接坝地区的玄武岩地,海拔1500m 以上,土层深厚,棕壤为主。光照充分,墒情好,绝大多数为退化草场,有沙化或潜在沙化的可能。绿化模式:搞大网格林草间作,林带200m,草带100m。机械带状整地,带宽60cm,带距2m,栽植落叶松,株距1.5m。2 阴坡、半阴坡特点:大部分为中厚层土,植被较好,水土流失较轻,部分有侵蚀沟出现。绿化模式:搞速生用材林.通过工程措施控制水土流失。根据坡
A high mountain Mandian Features: Mostly take the dam basalt area, elevation 1500m above, deep soil, mainly brown soil. Full of light, moisture is good, the vast majority of degraded pastures, there is the possibility of desertification or potential desertification. Green mode: Engaged in large forest grass intercropping, forest belt 200m, grass belt 100m. Mechanical belt preparation, width 60cm, with a distance of 2m, planting larch, plant spacing 1.5m. 2 shady slope, semi-shady slope Features: Mostly thick layer of soil, vegetation is good, soil erosion is light, some erosion ditch appears. Greening mode: engage in fast-growing timber forest, control soil and water loss through engineering measures. According to the slope
