| 摘 要： | 研究了不同种植模式下土壤养分的变化.试验结果表明,土壤碱解氯含量与有机质含量的变化呈正相关,土壤碱解氮含量可以反映土壤近期氮素供应情况.因此增加土壤有机质含量是提高土壤肥力的一种重要手段.化肥的施用是土壤速效钾的重要来源之一,农作物秸秆肥田对提高缺钾型土壤的速效钾含量有显著的效果.长期的蔬菜连作会加重土壤的负担,不利于城市近郊菜地的可持续利用,实行123种植模式(RVCs)有利于减轻土壤速效磷的富集. |

| Abstract: | The changes of soil nutrition in different cultivation mode were studied. The results showed that the soil alkalihydrolyzed N was positively related to the changes of organic matter content, and available N could reflect soil nitrogen supply lately, so increasing organic matter in soil is an important method to improve soil fertility. Fertilization is an important resource of available K in soil. Straw to field has a significant effect on available K in K deficiency soil. Long-term continuous cropping in ve... |
