以神东矿区60个土壤样品的实验室分析结果为原始数据,以1996年《第二次全国土壤普查技术规程》中“土壤养分含量分级与丰缺度指标”的标准对土壤肥力状况进行评价。结果表明:研究区土壤速效氮均处于4级水平,即“稍缺”;速效磷含量均为4-5级水平,即“稍缺”或“缺”;速效钾处于1级水平,即“丰”;土壤含盐量均超过0.1%,盐分类型为SO2-4+CL-+HCO-3-Na+型盐化碱土。总体来看,矿区土壤含盐,肥力水平低,加上土层薄,结构差,为满足植物生长的需要,造林种草前应适当施肥和改良土壤。
Based on the laboratory analysis results of 60 soil samples from Shendong Mining Area, the soil fertility status was analyzed based on the standard of “Soil Nutrient Content Classification and abundance Deficiency Index” in the “Technical Guidelines for the Second National Soil Census of 1996” Evaluation. The results showed that all the available N in the study area was at the level of Grade 4, ie, “Slightly Short”; the content of available P was at the level of Grade 4-5, ie “Slightly Missing” or “Lacking” 1 level, that is, “Feng”; soil salt content is more than 0.1%, salt type is SO2-4 + CL- + HCO-3-Na + type of saline alkaline earth. Overall, the salinity of soil in the mining area, low level of fertility, coupled with thin soil, poor structure, in order to meet the needs of plant growth, afforestation and grass should be properly fertilize and improve the soil.
