摘　　要：以两种粒径处理的玉米秸秆与猪粪按不同重量配比进行堆肥,堆肥时间61天,考察堆肥期间堆体温度、pH、氨氮、硝氮等参数指标变化,比较各项指标从而确定最优秸秆粒径及秸秆与猪粪的混合配比。经对实验数据的比较发现秸秆粒径为1cm、投加量为7%的处理在堆肥过程中获得良好效果。based on the two kinds of corn straw and particle processing according to different weight ratio on pig composting,composting,61 days time during composting of pile body temperature,pH,ammonia nitrogen and nitrate nitrogen and other parameters change,compared to determine the optimal index straw stalk of grain and mixed with pig ratio.By comparing the data of experiment,the particle 1cm straw for dosing quantity of 7% in composting process to obtain good effect.
