| 摘 要： | 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.

Afforestration Techniques for Gully Protection in the Gullied Hilly Loess Region in West Shanxi |

| Abstract: | Analysis of soil moisture and the growth of locust, a local typical species, shows that gully slopeswhich are suitable for planting trees in the gullied hilly loess region can be divided into three grades, and that site factors for afforestration in gully slopes can be divided into four types. Based on the classification of the grades and types, through analysis of afforestration experiment with different tree species and investgation report, specific tree species for different site factors are given. According to experiments and technical extension the following afforestration techniques are proposed and spread: deep planting, cluster planting of Chinese pine, water-collection forestry, afforestration in rainy season, soil covering of little trees in winter, using ABT agent to promote the growth of roots. |
