【摘要】：对地下式、保育仔猪、地上式发酵床等3种发酵床类型,表面、中层、底部等不同深度垫料的发酵温度和环境温度、基本理化指标和养殖生猪情况进行12个月的连续监测。结果表明,发酵床类型差异对垫料各指标影响不明显,不同发酵床类型表层垫料发酵温度受环境影响明显,而40~60 cm底层垫料作为主要发酵层,其垫料温度主要与养殖生猪的数量及其发育状态紧密相关。3种类型发酵床的表、中、底层垫料有机质含量和EC值总体表现为表层中层底层的变化规律;而粗灰分、pH值则呈现底层中层表层的变化趋势;全氮、全磷和全钾含量在3种类型发酵床表层、中层和底层垫料间总体表现为表层高于中层,中层高于底层的规律,三者间表现出极显著正相关性。
[Abstract]:The fermentation temperature, environment temperature, basic physicochemical index and pig breeding condition of three kinds of fermentation bed types, surface, middle layer, bottom and so on, were continuously monitored for 12 months. The results showed that the different types of fermenting bed had no obvious effect on the parameters of the gasket, and the fermentation temperature of the surface cushion was obviously affected by the environment, while the primary fermentation layer was 40 ~ 60cm bottom cushion. The bedding temperature was closely related to the number of pigs and their development status. The organic matter content and EC value of the bottom bedding showed the change rule of the surface layer and the bottom layer as a whole, and the table of the fermenting bed was closely related to the number and development state of the three types of fermenting bed. The content of total nitrogen, total phosphorus and potassium in the three types of fermentative bed was higher than that in the middle layer and the middle layer was higher than the bottom layer, and the content of total nitrogen, total phosphorus and potassium in the three types of fermentative bed was higher than that in the bottom layer, and the content of total nitrogen, total phosphorus and potassium was higher than that in the bottom layer. There was a very significant positive correlation among them.
