【摘要】 对华北平原大兴县 1 982— 2 0 0 0年两个时段大量土壤样本的分析结果表明 ,土壤养分含量与土壤质地表现出明显的一致性 ,体现了土壤质地越重 ,养分含量越高的特点 ;土壤质地对土壤养分含量的影响 ,1 982年的大于 2 0 0 0年的 ;但 2 0年来 ,由于土地利用集约度的增强 ,质地对土壤养分水平的影响渐趋减弱 ,不同质地土壤的养分水平渐趋一致更多还原

【Abstract】 We compared the plant nutrients in different texture soils in Daxing County, Beijing between 1982 and 2000. The results showed that plant nutrients were influenced by soil texture, the finer the texture, and the more nutrients the soil being found. The influence of soil texture on plant nutrients is greater in 1982 than in 2000. With fertilizer increasing, the soil nutrients content is getting uniform among different texture soils.更多还原
