摘要
为探讨黄土高原区露天煤矿沙棘混合配置下土壤生化特性及其与土壤肥力的关系,本文以准格尔旗黑岱沟露天煤矿人工复垦区为例,对沙棘灌丛、沙棘+3种不同类型植被配置及对照区的土壤微生物及土壤养分因子进行了测定和分析。结果表明:不同植被配置下土壤微生物数量均表现出差异性.土壤养分含量大致顺序为:沙棘+羊草>沙棘>杨树+柳树+沙棘>杨+沙棘;土壤微生物数量、土壤养分含量之间某些因子呈显著相关关系,可作为评价土壤肥力的指标。
To search for the correlation between soil biochemical characteristics and the soil fertility inmixed stands of Hippophae rhamnoides for land revegetation of coal mining site,soil microorganismand soil nutrients were analyzed with soil samples taken from one site of pure stand,three sites of different mixed stands of Hippophae rhamnoides with other plants,and a control site of newly disposal soil without plants in the Heidaigou Open-pit Coal Mining.Theresults are as follows: microorganismsamong the sites l ...
