本文根据多年试验和调查资料,通过对土壤水分和当地具有代表性的树木──刺槐活立木解析资料的分析,划分出了晋西黄土丘陵沟壑区的沟坡造林立地条件类型,即黄土阴沟坡、红土阴沟坡和黄土、红土阳沟坡三种立地类型;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:即刺槐、柠条、油松、侧柏等;最后根据试验和推广情况,从整地、苗木栽植等方面提出了六种实用造林技术,如深坑栽埴、油松丛植、集流林业、雨季造林、冬季埋土、ABT生根粉应用等。
Based on the data from many years of experiments and surveys, this paper analyzes the soil moisture and the representative tree species of Locusta acuminatum in the Loess Plateau, , Red soil gully slope and loess, red soil and Yanggou slope. According to the introduction, afforestation experiment and survey data, the suitable afforestation species under different site conditions were obtained: Robinia pseudoacacia, Caragana korshinskii, Pinus tabulaeformis, Arborvitae, etc. Finally, according to the experiment and popularization, six kinds of practical afforestation techniques were put forward, such as planted deep pit, Pinus tabulaeformis forest, current forestry, afforestation in rainy season, buried soil in winter, ABT rooting Powder applications.
