鸟粪石结晶反应在食用菌菌渣堆肥中的应用研究
Research on the application of struvite crystallization in the composting of edible mushroom residue
摘要
Abstract
To investigate the effect of adding phosphorus and magnesium to trigger struvite crystallization reaction in the edible mushroom residue composting system on composting efficiency,thereby promoting the resource utilization of mushroom residues,this study established 2 treatments:a control group and an experimental group.The control group was supplemented with edible mushroom residue,EM bacteria,and urea,while the experimental group was supplemented with edible mushroom residue,EM bacteria,urea,magnesium chloride,and potassium dihydrogen phosphate.During the fermentation process,parameters such as temperature,pH,electrical conductivity,total phosphorus,available phosphorus,and alkali-hydrolyzable nitrogen content of the compost were monitored.The results showed that there was little difference in temperature changes between the experimental and control groups.In the early stage of composting,the pH of the control group was higher than that of the experimental group,but it gradually converged in the later stage.The electrical conductivity of the experimental group was consistently higher than that of the control group throughout the composting cycle,though both remained within safe limits.The total phosphorus,available phosphorus,and alkali-hydrolyzable nitrogen contents in the experimental group were all higher than those in the control group.At the end of composting,the total phosphorus,available phosphorus,and alkali-hydrolyzable nitrogen content in the experimental group were 2.58,13.02,and 1.83 times higher than those in the control group,respectively.In conclusion,the struvite crystallization reaction can significantly reduce nitrogen and phosphorus loss in mushroom residue composting and effectively improve the quality of the compost.This study provides a reference for the resource utilization of mushroom residues.关键词
