蚯蚓对牛粪中碳、氮及其他营养物质转化的影响
Effect of earthworm on conversion of carbon, nitrogen and other nutrients in cow dung
摘要
Abstract
Six plots were used as the earthworm digestion bed on the Guihe cattle farm in Feidong county,Anhui.New milk cow dung was heaped by uniform ridge in the bed.The experiment compared the changes of the physical and chemical properties between natural composting and earthworm composting (vermicomposting)treatments.Results showed that pH,total carbon,organic carbon,total nitrogen,total potassium content of the earthworm composting treatment were lower than the traditional natural composting material.The total phosphorus,available phosphorus,available nitrogen,and available potassium were higher in the earthworm than the natural composting treatment.Percentages of available nitrogen and available phosphorus in the cow dung treated with earthworms gradually increased.The cow dung vermicomposting accelerates the mineralization of the composting material and thus improves the available nutrient content.关键词
