脲酶抑制剂NBPT对水泡粪猪舍粪尿氮素转化及氨挥发的影响
Effect of urease inhibitor NBPT on fecal and urine nitrogen conversion and ammonia volatilization in blister manure pig barns
摘要
Abstract
In order to investigate the effect of urease inhibitor N-butylthiophosphorotriamine(NBPT)on nitrogen emission during feces and urine storage in blister pig pens,fresh pig feces and urine was taken as study material in this study and a total of six treatments,blank control treatment(CK),and the 0.02％(T1),0.04％(T2),0.06％(T3),0.08％(T4)and 0.10％(T5)of NBPT addition treatments were designed with three replicates per treatment,the storage experiment lasted for 25 days.The characteristics of nitrogen conversion and loss in feces and urine and the abatement cost of each treatment were compared.The results showed that:Compared with CK,the NBPT treatments could significantly reduce ammonia emission by 13％to 54％(P＜0.05)through reducing the decomposition and transformation of urea in feces and urine,and the ammonia emission reduction effect showed a significant increase and then stabilized with the increase of the proportion of NBPT addition;Among them,T5 treatment had the best abatement effect but also had the highest abatement cost.T2 treatment had the highest ammonia abatement per unit cost(106 g/yuan),and it had the ammonia abatement potential of 37％.In conclusion,the addition of urease inhibitor NBPT to blister manure pens can effectively reduce ammonia emissions,and the 0.04％additive dose is recommended in actual production.关键词
