设施土壤连作障碍电处理试验研究

连作障碍是设施农业生产中的常见问题,严重影响着作物的产量和品质。目前,设施土壤连作障碍一般采用施肥或施药等化学方法对土壤进行消毒处理,但这样会造成土壤环境的二次污染,而利用电处理技术对土壤进行物理处理会避免这一问题。从土壤理化性质着手,以土壤中氮、磷、钾等营养元素含量为指标,通过试验研究及方差分析,验证电处理技术对土壤元素含量的变化有着显著的作用。

Experimental Study on Electric Treatment on Continuous Cropping Obstacles in Greenhouse Soil

Continuous cropping obstacle is a common problem in facilities agriculture production which brings a negative effect on crop’s yields and qualities.At present,fertilization,spraying and other chemical methods are used to sterilize soil in greenhouse soil to eliminate continuous cropping obstacle.But this will cause the secondary pollution to soil environment,the use of electric treatment technology for soil by physical processing would avoid this problem.Based on physical and chemical properties of soil,with nitrogen,phosphorus,potassium and other nutrients content as the index,the experiments and variance analysis showed that the elements of soil were changed significantly by electric treatment technology.
