| 摘 要： | 试验地位于安徽肥东县桂和养牛场,选择6个地块作为消解床,新鲜奶牛粪采用均匀堆垄铺在消解床上。分析了60 d内奶牛粪便自然堆制和蚯蚓堆制2种处理方式的堆制物的理化性质。结果表明,蚯蚓粪p H、总碳、有机碳、全氮、全钾含量均低于传统的牛粪自然堆制物,全磷、速效磷、速效氮和速效钾均高于牛粪自然堆制物,蚯蚓粪的速效氮和速效磷占全氮和全磷的百分比均分别逐渐升高。由此认为,与自然堆制相比,牛粪蚯蚓堆制加快了堆制物矿化速率,提高了堆制物速效养分含量。

| 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. |
