摘　　要：为对霉变玉米青贮进行资源化利用,缓解其对养殖环境带来的压力,采用条垛式堆肥方法,将牛粪与霉变玉米青贮混合,添加发酵菌种后进行堆肥发酵,探索其发酵效果。结果表明,与对照组相比,试验组能延长堆体高温期持续时间;堆肥最终pH为8.0~9.0,且pH大小与物料的性质和不同成分的配比有一定的关系;总氮和铵态氮含量呈降低趋势,而总养分、P_(2)O_(5)和K_(2)O含量均呈不同程度升高的趋势;在堆肥末期,所有处理组均未能达到对白菜种子无毒的标准,这可能与物料pH以及霉变玉米青贮含有霉菌毒素有关。In order to utilize moldy corn silage as a resource and relieve its pressure on the breeding environment,the cow dung and moldy corn silage was mixed with fermenting strains,and then compost fermentationwas carried out and its fermentation effect was explored by stacked composting method.The experimental results showed that compared with the control group,the experimental group could extend the duration of the high temperature period of the pile;The final pH of the compost was between 8.0 and 9.0,and the pH had a certain relationship with the nature of the material and the ratio of different components;The contents of total nitrogen and ammonium nitrogen showed a decreasing trend,while the contents of total nutrients,P_(2)O_(5) and K_(2)O all showed increasing trends to varying degrees;At the end of composting,all treatment groups failed to reach the standard of non-toxicity to cabbage seeds,it may be related to the pH of the material and the mycotoxins contained in moldy corn silage.
