添加菌剂和石灰对剑麻渣腐解及养分含量的影响
Effects of Adding Microbial Inoculants and Lime on Fermentation and Nutrient Content of Sisal Waste
摘要
Abstract
To explore the optimal fermentation conditions and the effects of additives for sisal waste,and to improve the quality of sisal waste compost,a fermentation experiment was conducted using sisal waste as the test material.The experiment was set up with 2 fermentation conditions(aerobic and anaerobic)and 4 additive treatments(no additives,microbial inoculants alone,lime alone and a combination of microbial inoculants and lime).The color,smell and nutrient content of the sisal waste fermentation products were measured.The results showed that,under aerobic condition,the color of the fermentation products generally changed from yellow to brown,while under anaerobic condition,the trend was the opposite.The rancidness smell of sisal waste fermentation products was stronger under anaerobic condition compared to aerobic condition.Adding microbial inoculants under aerobic condition reduced the rancidness smell of the products,while adding lime reduced the rancidness smell under both aerobic and anaerobic conditions.The pH of the fermentation liquid under anaerobic condition(5.0～8.3)was generally lower than that under aerobic condition(7.4～8.9).The total nitrogen,phosphorus and potassium contents of the solid-state fermentation products of sisal waste treated with different methods were 11.3～19.5,1.8～3.8 and 0.9～4.3 g·kg-1,respectively,while the fermentation liquid had total nitrogen,phosphorus and potassium contents of 39.9～233.3,5.0～153.5 and 0.58～0.85 mg·kg-1,respectively.The addition of inoculants resulted in the highest total nitrogen and phosphorus contents in solid-state fermentation products,averaging 17.6 and 3.5 g·kg-1,respectively,under aerobic condition.Compared to the 2 fermentation conditions,the phosphorus content of the fermentation liquid under anaerobic condition was generally higher than those under aerobic condition,especially with the addition of inoculants,where it significantly increased,averaging 84.5 mg·kg-1.Under the same additive treatments,the overall mass loss rate of sisal waste under anaerobic condition was lower than that under aerobic condition.The addition of lime significantly reduced the mass loss rate of sisal waste.The potassium loss rate of sisal waste was relatively high,reaching 75.9%～82.2%.In conclusion,sisal waste performed better under aerobic condition for fermentation,microbial inoculants facilitated the decomposition of sisal waste,and lime could reduce the smell of sisal waste fermentation products.However,the effectiveness of inoculants decreased when mixed with lime.It was recommended to use aerobic condition with the addition of microbial inoculants and a small amount of lime for the fermentation treatment of sisal waste in production.关键词
