酒糟型生物有机肥初始酵解条件对氮素损失的影响

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%。

Effects of original zymolytic conditions on nitrogen loss of brewer's spent grains-based bio-organic fertilizer

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 ...
