摘要
本文测定分析了内蒙古典型草原马粪、牛粪和羊粪分解过程中活性有机磷含量的变化。3种鲜粪中活性有机磷的含量次序为马粪>羊分>牛粪;在分解过程中,3种粪中活性有机磷含量的变化形式差别较大,马粪中活性有机磷含量与季节变化明显相关,春季和秋季含量增加,夏季含量降低;牛粪中含量变化幅度较小;羊粪中活性有机磷含量分解前期增加,后期降低。家畜粪埋入地下处理导致分解过程中有机磷含量降低,变化形式基本不变。
This paper analyzes the active organic phosphorus changes in horse dung, cattle dung and sheep dung, which are from the Inner Mongolia Typical Steppe. In three kinds of fresh dung the order of active organic phosphorus contents is horse dung〉 sheep dung〉 cattle dung. In the process of decomposition, the difference of three kinds of dung is relative to the season, in spring and autumn, the contents of it increased, in summer the contents decreased. The contents of active organic phosphorus in cattle dung changed a little. For the sheep dung, at the beginning, the contents increased, then decreased. Stacking the livestock dung into the floor made the active organic phosphorus content decrease, but the forms nearly keep the same.
