摘 要 ：试验应用二次通用回归旋转组合设计四因素（1/2实施）方案，研究酒糟型生物有机肥堆制初始条件对氮素损失率的影响，以期为有效控制氮素损失提供理论依据。结果表明，各因素对氮素损失率的影响大小顺序是： pH值>接种量>秸糟比>含水量； 当pH值、接种量的编码值为-1.68，含水量、秸糟比的编码值为1.68时，氮素损失率最小，为8.4164%。四个因子间存在着交互作用，且作用方向是正向的，其中pH值与含水量、接种量与秸糟比间的交互作用不显著。在本试验条件下，控制氮素损失率的最优方案是： pH值6.3980～6.4186、接种量0.3991%～0.4031%、含水量64.7014%～64.8285%、秸糟比40.9326%～41.0956%。

Abstract:An experiment was conducted to study the effects of original zymolytic conditions on nitrogen loss of brewer‘s spent grains-based bio-organic fertilizer by using the quadratic uniform-precision rotatable central composite design including four factors and five levels. The result shows that the order of each factor‘s influence to nitrogen loss is: pH value > inoculation fungal biomass > ratio of straw to lee > water content. There are positive interactions between the four factors and the interactions between pH value and water content and between inoculation fungal biomass and ratio of straw to lee are not significantly different. In this experiment, the suitable ranges of pH value, inoculation fungal biomass, water content and ratio of straw to lee are: 6.398-6.4186, 0.3991%-0.4031%, 64.7014%-64.8285% and 40.9326%-41.0956%, respectively.
