摘要
采用4种整地技术,分析了不同整地方式对侧柏、刺槐、花椒、枣树、沙棘、火炬树、臭椿、黄栌和油松等9个树种成活率及新梢生长的影响。结果表明:成活率和新梢生长量从高到低的顺序是:梯田整地、水平阶整地>鱼鳞坑整地>常规整地。在废弃煤矿绿化过程中,建议采用梯田整地和水平阶整地。
The effects of different land preparation modes on the survival rate of nine kinds of species (P latycladus orientalis ,Robinia pseudoacacia ,Robinia pseudoacacia ,Ziziphus j uj ube ,Hippophae rhamnoides ,Rhus typhina , Ailanthus altissima ,Cotinus coggygria & Pinus tabuliformis )and growth of new shoots were analyzed by adop-ting four land preparation techniques.Result shows that the descending order of the survival rate and the growth of new shoots is:land preparation on terrace and land preparation on level bench>land preparation on fish-scale pits>conventional land preparation.Land preparation on terrace & land preparation on level bench should be used in the process of waste coal mining.
