在普通土壤中施入不同质量的啤酒厂废硅藻土作为土壤改良剂,湿润培养3个月后,测定土壤物理指标及团粒结构.试验结果表明,当土壤中废硅藻土含量在10%时,土壤容重相对较低,土壤孔隙度相对较大,水稳性团聚体含量达到最大,土壤分形维数相对较低.结论:啤酒厂废硅藻土对土壤结构有明显的改良作用,当废硅藻土含量为10%时,对土壤的改良效果最佳. In normal soils, waste diatomite from different breweries was used as soil conditioner, and after 3 months of wet culture, soil physical indicators and aggregate structure were determined.The results showed that when the content of waste diatomite in the soil was 10% , The soil bulk density is relatively low, the soil porosity is relatively large, the content of water-stable aggregates reaches the maximum, and the fractal dimension of soil is relatively low.Conclusion: The waste diatomite from brewery can significantly improve the soil structure, Waste diatomite content of 10%, the best soil improvement.
