| 摘 要： | 为阐明矿区工程复垦后,农业措施对复垦土壤有机质和土地生产力的影响,以原平露天矿区复垦地为研究对象,比较了人工农业措施干预下的复垦地和自然恢复的复垦地土壤有机质含量和土地生产力的变化,同时分析了有机质和土地生产力之间的相关性。结果表明:施肥尤其是有机肥施用相对自然恢复可以显著提高复垦土壤有机质含量;方差分析表明,在种植相同作物情况下,有机肥+无机肥处理能显著提高土壤有机质含量,同时提高复垦土地生产力;相关分析表明,有机质和土地生产力之间存在显著的线性正相关关系。

| Abstract: | To elucidate the impact of agricultural measures on soil organic matter and land productivity after the mining engineering reclamation,taking the open-pit mine reclamation land in Yuanpin as the research object,this paper analyzed the change of the organic matter content and land productivity on the reclamation land by comparing the artificial agricultural measures with the natural recovery soil.At the same time,it analyzed the correlation between organic matter and land productivity simultaneously . The results showed that①Fertilization measures,especially relative to the natural recovery,organic fertilization could improve significantly content of the reclamation soil organic matter;②Variance analysis showed that under the condition of planting the same crop,OM＋CF could increase significantly the content of the soil organic matter and the productivity;③Correlation analysis showed that there was significant linear correlation between the organic matter and the land productivity. |
