摘要
为了解决有机无机复合肥施用前期氮释放过快问题 ,配制了 9种氮缓释剂 ,并以尿酶活性、硝化抑制率和肥料施入土壤后释放无机氮总量为指标对缓释剂进行选择比较。在 9种缓释剂中选用H6作为LF3- 3稳定性复合肥的添加剂效果很好。
In order to solve the problem of nitrogen high releasing rate at the early stage after the organic inorganic compound fertilizer was applied to the soil,nitrogen reduced releasing agents were introduced.To compare and select the agents,urease activity,nitrifying inbibiting rate and total inorganic nitrogen (released after the fertilizer was applied to soil) were measured.It showed that the reduced releasing agent H6 is the most effective one in these nine as additive of the stable compound fertilizer (LF3 3).
