尿素为氮源的缓释肥中氮素转化速率研究

Research on N Transforming Rate of Slowreleased Fertilizers Taken Urea as N Source

对不同缓释肥中尿素氮转化速率的研究表明，脲酶抑制效果较好的缓释剂为氢醌和糠醛，用其制成的缓释肥在氮素转化速率、释放总量方面与产量相关性较好，可作为缓释肥的添加剂加以开发应用。

The research determined N element′s transformed speed of different slowreleased fertilizer, picked out several slowreleased agents that its control effect is quite good {C5H4O2 and C6H6O2} The results indicated, adopting slowreleased fertilizer, made of above mentioned two materials, the interrelation between N element transformed speed and released amount with crop production is quite good close It can use and develop for addition agents of slowreleased fertilizer
