【摘要】 本试验研究了露天自然堆储、露天自然堆储加遮雨棚和储粪池加盖堆储三种堆储方式对牛粪中氮磷的含量变化的影响。氮磷测定采用有机肥料的测定方法。试验结果表明:在堆储的不同时期,全氮浓度先下降后回升,堆储后与堆储前没有太大的变化,但是,在堆储后期,储粪池加盖堆储处理组的全氮、速效氮含量高于其他两个处理组。3个处理组的全磷的含量随着堆储时间的延长而不断增加,到75d时达到稳定,在整个过程中,储粪池加盖堆储组的全磷含量一直高于其他两个处理组。更多还原

【Abstract】 Change of nitrogen and phosphorus content of beef manure stockpiled in three methods (open air stockpile,manure pit stockpile and manure pit with shed stockpile) during different period were studied.Contents of nitrogen and phosphorus of beef cattle feces were determined according to the methods for organic fertilizer.The results showed that the content of total N decreased at first and then increased and there was no significant difference among the three treatments before and after the treatment,however,in the later period of stockpile,it is higher in manure pit with shed stockpile group.The contents of total P in three treatment groups increased as the time longs,and approached to steady at the 75th day of the treatment.For the whole stockpile period,the contents of total P in manure pit with shed stockpile group were higher than those in the other two groups.更多还原
