| 摘 要： | 在土壤养分调查的基础上,系统分析了忻府区土壤4种养分特征。结果表明,农田土壤养分中有效磷的变异系数最大;较第二次土壤普查时忻府区农田土壤养分有了一定的积累,但仍有50%左右的土壤碱解氮和磷含量属于低水平,90.0%的土壤有机质属于低肥力水平;各乡镇的土壤肥力也有明显差异,特别是阳城乡和高城乡。

| Abstract: | On the basis of data,soil nutrient content of farmland was analyzed systematically in Xinfu area.The results showed that available phosphorus had the biggest coefficients of variation.nitrogen and phosphorus nutrient of farmland soil in Xinfu area increased with fertilization increase from 1980s,available phosphorus and nitrogen contents of 50% soil and organic matter of 90.0% soil belong to low fertility level.Soil fertilities in different towns varied greatly and were affected by economic efficiency and f... |
