摘要
为探讨有机肥替代化肥条件下的土壤质量特征,通过建立20个设施蔬菜土壤监测点,分析有机肥替代化肥前后的土壤理化指标,再进行单因素描述和指数和法评价分析,科学掌握设施蔬菜土壤的质量状况,为合理的设施蔬菜土壤培肥措施提供理论依据。结果表明,单因素评价得出有机肥替代化肥后,土壤酸碱缓冲容量增加,土壤有机质、有效磷和速效钾含量增加,碱解氮处于较低水平,蔬菜品质得到有效改善,茄子和包菜的维生素C和可溶性糖含量增加,硝酸盐含量降低,指数和法评价得出有机肥替代化肥后的土壤质量得到有效提升,表明有机肥替代化肥措施有利于土壤质量提升和可持续性。
In order to explore the soil quality characteristics under the condition of chemical fertilizer replacement with organic fertilizer,20 observation sites of vegetable soil were established to scientifically grasp the vegetable soil quality by analyzing the soil physical and chemical data before and after organic fertilizer replacing chemical fertilizer,and carrying out single factor and index evaluation analysis.It provided a theoretical basis for reasonable soil fertility of vegetables.The results showed that the soil acid-base buffer capacity increased,the contents of soil organic matter,available phosphorus and available potassium increased,the alkali hydrolyzable nitrogen was at a low level,the corresponding vegetable quality was effectively improved,the contents of vitamin C and soluble sugar of eggplant and cabbage increased,and the content of nitrate decreased after organic fertilizer replacing chemical fertilizer.The index method evaluation showed that the soil quality has been effectively improved after organic fertilizer replacing chemical fertilizer.It was suggested that organic fertilizer replacing chemical fertilizer was good for the improvement and sustainability of soil quality.
