微生物制剂促进鸡粪堆肥腐熟和臭味控制的研究

A STUDY ON COMPOST PROCEDURE ACCELERATION AND ODOR CONTROL OF CHICKEN MANURE COMPOST BY A MICROBIAL PREPAPATION

鸡粪中添加微生物制剂ＥＭ，堆制２０ｄ堆肥腐熟，较传统堆制法腐熟进程明显加快，堆制９ｄ后堆肥散发出酿酒的芳香。ＮＨ４＋－Ｎ含量下降４１．９４％～５６．７４％，除臭效果显著。ＥＭ能显著提高堆肥中有机质和氮素的保留率，减少氮的气态损失。ＥＭ的除臭功能与其促进堆肥中大分子有机物转化为小分子芳香有机物和ＮＨ４＋－Ｎ向其他形态氮的转化有关。

Chicken manure was well composted in 20 days with addition of the microbial preparation EM.The compost procedure was much shorter than with traditional,nethods.Aromatic smell was given off from the chicken manure comPOst with EM after 9 days' composting.-N content in the chicken manure compost with EM was reduced by 41.94% ～56.74% so which made a significant deodorant effect.Contents of residual organic matter and nitrogen in the compost with EM were increased significantly and N gaseous loss was reduced. EM deodorization effect possibly results from organic macromolecular componds transforming to aromatic organic micromolecular componds and NHt-N transforming to other N forms.
