上海地区高效生态蔬菜茬口土壤质量监测与分析

Monitoring and Analysis on Soil Quality of Efficient Ecological Vegetable Crop in Shanghai

通过调研选定3种设施蔬菜高效生态茬口模式,针对3种茬口模式开展土壤质量定点监测,采集土壤样品进行相关指标测定并对检测结果进行分析。结果表明,经过1a蔬菜生产,3种高效生态蔬菜茬口模式土壤pH值、全盐量、硝态氮以及速效氮、磷、钾等指标全年变化较为均衡,土壤保育良好。

Through investigation and research,we selected three kinds of efficient facility vegetable crop models and monitored soil quality in fixed points.In addition,we determined relevant indicators of collected soil samples and then analyzed the test results.The results showed that,after a year of vegetable production,the indicators including pH value,contents of total salt,nitrate nitrogen,available nitrogen,phosphorus and potassium changed relatively balanced throughout the year,indicating that soil conservation was good.
