摘要
研究了沼肥对山药土壤肥力、主要微生物类群及酶活性的影响。结果表明,与农家肥比较,沼肥增加了山药土壤的全量养分、速效养分含量及细菌、放线菌、真菌及氨化细菌的数量,也提高了蔗糖酶、中性磷酸酶、脲酶及蛋白酶的活性。沼肥对山药土壤有较好的培肥作用。
The effect of biogas on the soil fertility,main microbial flora and enzyme activity of the yam soil were studied.The results showed that compared with farmyard manure,biogas manure increased total and available nutrient content,the number of bacteria,actinomycetes,fungi and ammonfying bacteria,the activity of invertase,neutral phosphatase,urease and protease of the yam soil.Biogas manure had good fertility betterment effect on yam soil.
