Effect of EM Bokashi application on control of secondary soil salinization

In order to ameliorate saline-alkaline soil, EM Bokashi has been applied to rice production in conjunction with subdrainage in Ningxia Autonomous Region and Zhejiang Province. The preliminary results can be summarized as follows： EM Bokashi can increase soil organic matter content, improve soil porosity and permeability, and raise the soil＇s levels of available nutrients; and EM Bokashi combined with subdrainage treatment is more effective in controlling secondary soil salinization and raising the grain yield and quality than other treatments. The results suggest that EM Bokashi can reduce the necessary amount of chemical fertilizer application, thereby improving the agricultural environment, and that the introduction of EM Bokashi into systems of secondary soil salinization control systems has resulted in significant benefits.

EM微生物制剂在河湖淤泥无害资源化处理上的应用研究

验证EM微生物制剂对淤泥的处理效果,提高淤泥的利用效率,寻求EM处理淤泥的最佳处理方法,为淤泥的无害资源化利用提供一种可行的技术途径。试验证明,添加30%EM波卡西处理效果最好:汞含量由0.21 mg/kg降至0.14 mg/kg,降幅约35%;砷含量由4.8 mg/kg降至2.9 mg/kg,降幅达40%;铜含量由40.6 mg/kg降至28.7 mg/kg,降幅达29%;铅含量由28.6 mg/kg降至17.3 mg/kg,降幅达40%;镉含量由0.18 mg/kg降至0.07 mg/kg,降幅达60%;粪大肠菌群值由0.0009升至0.0420,约升高400%。研究结果表明,EM有益微生物在河湖淤泥处理上具有良好的应用效果,提高淤泥的资源化利用效率,值得推广应用。
