摘　　要：研究了沼液对土壤生物学性质的影响。结果表明,沼液能够显著改善土壤脲酶、多酚氧化酶、蔗糖酶、无机焦磷酸酶和磷酸脂酶的酶活性,从而增强土壤中作物所需营养物质的矿化,提高土壤肥力;同时,沼液能增加土壤细菌、酵母菌、真菌、放线菌的数量,且沼液组的微生物多样性指数相对较高。Effect of biogas liquid on biological properties of soil was studied.The results showed that biogas liquid increased the activity of the soil urease,polyphenol oxidese,inorganic pyrophosphatase,invertase,phospholipase,enganced the mineralization of the crop nutriment and increased soil fertility.The biogas liquid could also increase the quantity of the microorganism such as bacteria,fungus,actinomyces and microzyme,and the microorganism diversity of the biogas liquid groups was higher than that of other groups.
