摘　　要：为了解一定含水量条件下添加氮源对松树皮腐熟的影响,将含水量为60%～65%的松树皮进行腐熟试验,测定添加氮源对松树皮腐熟效果的影响。结果表明：经腐熟处理的松树皮,理化性能均得到较大的改善;添加10%含量尿素做氮源的松树皮粒径含量变化较多,密度变化较大,理化性质变化较多,C/N比从初始的63.33%变为15.83%。可见添加10%含量尿素做氮源的松树皮腐熟效果较好。With the purpose of finding out the influence of adding nitrogen source under the condition of a certain moisture content,we detected pine bark containing 60%-65% water,and analyzed the influence of adding nitrogen source. The results showed that,the physical and chemical properties of the pine bark with different treatments were improved greatly,after pine bark added with 10% content of urea,the change of particle content,volumetric weight,the physical and chemical properties were more significant than the others. C / N ratio reduced from the initial 63. 33% to 15. 83%. Adding 10% content of urea as nitrogen source was better in pine bark rotten.
