通过对土壤水分和当地具有代表性的树种——刺槐活立木解析资料的分析,将晋西黄土丘陵沟壑区的沟坡宜林地划为三个质量等级,将沟坡造林立地条件划分为黄土阴沟坡、红土阴沟坡和黄土阳沟坡、红土阳沟坡四类型;在此基础上,根据引种、造林试验和调查资料,得出了不同立地条件下的适宜造林树种.依据试验和推广情况,提出了深坑栽植、油松丛植、集流林业、雨季造林,冬季幼树埋土、ABT生根粉浸根等宜在晋西黄土丘陵沟壑区推广的实用造林技术.
Based on the analysis of soil moisture and the representative tree species of Locust - Locust Tree, the gully slopes in the loess hilly and gully regions of Shanxi Province are classified into three quality grades, and the site condition of the slope - gully afforestation is divided into loess gully Based on the introduction, afforestation test and survey data, the suitable afforestation tree species under different site conditions were obtained.According to the situation of experiment and popularization The planted planting of Pinus tabulaeformis, Pinus tabulaeformis, flow collecting forestry, afforestation in rainy season, buried young winter trees, ABT rooting powder and so on should be applied in the afforestation techniques of loess hilly and gully regions in western Shanxi Province.
