牛粪经蚯蚓消解前后理化性质及养分含量的比较研究
Comparative study on the physicochemical properties and nutrient content of cow manure before and after digestion by earthworms
摘要
Abstract
The aim of this experiment was to explore the optimization effect of worm decomposition on the resource utilization of cow manure.Using'Daping No.2'earthworms(Amynthasma inexpectatum)as the treatment carrier,the changes in physical and chemical properties and nutrient contents of cow manure before and after worm decomposition were compared and analyzed.The results showed that compared with fresh cow manure,worm-treated cow manure extremely reduced its pH value,organic matter mass fraction(P<0.01),reduced the contents of nitrogen and potassium,and increased the phosphorus content.The worm-decomposed cow manure did not detect total cadmium,total chromium,total mercury,total arsenic content,fecal Escherichia coli colony count,and the mass fraction of chloride ions were lower than those of fresh cow manure,and the seed germination index was higher than that of fresh cow manure.The study showed that using worm decomposition of cow manure could improve the overall quality of compost,which is of great significance for promoting agricultural resource recycling and the development of ecological agriculture.关键词
