本文通过室内好气培养试验和盆栽试验，研究了不同用量的兽角在不同土壤上的无机氮释放规律及肥效。试验结果表明，好气培养２周内，兽角无机氮释放速率和释放量均较高，兽角中有２８％～５２％的氮以无机氮的形式释放出来。２周以后，兽角无机氮的释放速率和释放量显著下降。兽角的用量及土壤类型对兽角无机氮的释放有显著的影响。在等氮量的情况下，施用兽角对盆栽油菜可以起到和施用化肥相同的增产效果
In this paper, indoor aerobic culture experiments and pot experiments were conducted to study the law of inorganic nitrogen release and fertilizer efficiency in different amounts of animal horns on different soils. The results showed that during the two weeks of aerobic culture, the release rate and release of inorganic nitrogen in animal horn were high, and 28% -52% nitrogen in animal horn was released as inorganic nitrogen. After 2 weeks, the release rate and release of inorganic nitrogen in animal horn decreased significantly. The amount of beehive and the type of soil had a significant effect on the release of inorganic nitrogen in beast horn. In the case of equal nitrogen, the application of animal horns on potted rape can play the same yield and application of fertilizer
