对山西省62个主要耕作土壤种类、耕层土壤肥力现状进行了调查分析,并与第二次土壤普查情况进行比较,结果表明,依据山西省耕地土壤养分分级标准评价,有效磷属2级水平,有机质、有效钾、阳离子代换量属3级水平,全氮属4级水平;与第二次土壤普查情况相比,除有效钾呈下降状态外,有机质、全氮、有效磷、阳离子代换量均呈上升状态.说明山西省耕作土壤肥力与土壤普查时相比有大幅度的提高,但是存在养分间发展不平衡现象.为此,提出增施有机肥、大力实施测土配方施肥及秸秆还田技术等相应的培肥对策,以达到七壤养分平衡发展,保证农作物持续优质、高产、稳产.

For 62 wajor soil patterns of cultivated land in Shanxi,tilth top soil fertility was investigated and compared mth the conditions in the 2nd Soil Census.The results showed that:based on nutrition grading standard in Shanxi.the available P standed in grade 2,organic matter,available K,positive ion exchange in grade 3 and whole N grade 4;compared with the 2nd Soil Census the organic matter,whole N,available P,positive ion exchange all showed a raising situation,except available P.The situation suggested that soil fertility of cultivated land in Shanxi had improved remarkably since the last soil census,though there existed unblance between nutrients.Thus.fertilization recommendation to increase organic fertilizer,to populize soil-test-formulation-fertilization and fodder rutuming was made for aim of a balanced development of soil nutrition and sustainable fine quality,hish and stable yielding of cultivated crops.
