羊粪、食用菌菌渣及鸡粪混合堆肥的效果研究
Effects of Co-composting of Sheep Manure,Edible Fungus Residue and Chicken Manure
摘要
Abstract
In order to solve the problem of recycling waste in intensive and large-scale livestock and poultry production,the composting effects of mixing edible fungus residue,chicken manure and sheep manure were investigated.In this study,sheep manure was used as the main composting material,com-bined with different proportions of chicken manure,edible fungus residue and sodium selenite.CK,GA,GB and GC groups(sheep manure content was 100％,70％,60％and 50％,respectively)were designed,then were inoculated with fecal microbial fermentation bacteria and mixed for aerobic composting.By de-tecting the temperature,pH value of the compost,the physical,chemical and biological indexes of the compost and the quality characteristics of the organic fertilizer after fermentation,the optimum ratio of sheep manure,chicken manure and edible fungus residue for mixing aerobic compost was determined from the aspect of manure fertilizer.The results showed that compared with the control group,GA,GB and GC treatments shortened the heating time,increased the compost temperature for 2～3 ℃,and prolonged the high temperature time at the same time,and the GC treatment had better heating effects than GA and GB;On the 15th day of composting,all test groups had the highest pH value,and the pH value of GC was the highest.When the composting was completed,the TN,TP and total nutrient contents of GA,GB and GC treatments were all significantly improved(P＜0.01)compared with CK,and the organic matter content of GC was higher than that of GA and GB.The heavy metal content,the mortality of roundworm eggs,and the number of fecal coliforms in the 4 treatments all met the standard of NY 525-2012"Organic Fertiliz-er".Based on the above results,the mixing ratio of GC treatment(50％sheep manure+20％chicken ma-nure+30％bacteria residue)has the best composting effect and organic fertilizer quality.This ratio is pref-erably used to treat sheep manure,chicken manure and edible fungus residue as fertilizer treatment.关键词
