摘要
对尿素 +缓释剂 Q、尿素 +缓释剂 K、尿素 +缓解剂 S的氨态氮挥发进行模拟试验 ,结果表明 ,0 .1 %～ 0 .5 %的缓释剂 Q、0 .3 %～ 1 %的缓释剂 K、1 %～ 2 %的缓释剂
A simulating experiments for testing volatilization velocity of ammoniac nirtogen in different slow release urea has been finished. The conclusion shows those three kinds of slow release agents, 0.1%～0.5% of Q, 0.3%～1% of K and 1%～2% of S, may significantly slow down the ammonia nitrogen release of urea so as to have a remarkable effect.
