牛粪分别与棉籽壳、切碎棉花秸秆、锯末以9:1(体积比)混合,将初始水分调整60%后堆成条垛进行静态发酵堆肥,探讨不同副资材对牛粪高温发酵堆肥化效果的影响。结果表明,堆肥2日内进入60℃以上的高温期,45 d后无明显升温达到无害化处理水平。腐熟堆肥的有机质含量明显降低,全氮含量小幅度下降,但全磷和全钾含量无明显变化,有机质和总养分含量均高于腐熟有机肥NY-525标准。牛粪通过上述方法制作堆肥两个月均可以达到腐熟堆肥标准。
Cow dung and cotton seed hulls, respectively, shredded cotton stalks, sawdust at 9: 1 (volume ratio), the initial water 60% adjusted after the stack into a static fermentation composting to explore different auxiliary materials high temperature fermentation of manure composting Effect of effect. The results showed that composting entered high temperature above 60 ℃ within 2 days and no significant warming reached the level of harmless treatment after 45 days. Compost composted organic matter content decreased significantly, total nitrogen content decreased slightly, but the total phosphorus and total potassium content did not change significantly, organic matter and total nutrient content were higher than the compost organic fertilizer NY-525 standard. Cow manure composting by the above method can reach the compost compost standard two months.
