蚯蚓堆肥处理对不同物料农化性质的影响
Effect of Earthworm Composting on Agriculture Chemical Characteristics of Different Material
摘要
Abstract
[Objective] The objective was to study the change of the main agriculture chemical characteristics between raw material and earthworm faces. [ Method] Earthworm composted different ratio cattle manure,liquid,sludge and litter. [ Result] The results showed that pH closed to 7 and the contents of EC all increased. But compared the raw material with earthworm faces,the contents of the total N and available N descended excepted the treatment of 30％ cattle manure + 70％ sludge. The total P increased by 0 to 101.8％ and available phosphorus increased by 13.6％ to 57.2％ ,the contents of available K increased by 6.9％ to 33.7％. Earthworm composting accelerated the decomposition of organic matter. On the whole,the two treatments of 30％ cattle manure + 70％ sludge and 100％ litter increased the most contents of available nutrient.And the quanity of bacteria,actinomycetes and fungus were higher than those of the treatment of 100％ cattle manure. [Conclusion] By earthworm composting,it could increase the contents of available nutrient and the number of microorganism. 30％ cattle manure + 70％ sludge and 100％ litter were the best.关键词
