脲酶抑制剂在水稻增产中的应用研究进展

Research Progress in the Application of Urease Inhibitor to the Yield Increase of Rice

尿素对提高水稻产量起着至关重要的作用,但土壤中广泛存在的脲酶会引起尿素的快速水解,极大地降低水稻对氮素的利用。添加脲酶抑制剂能延缓尿素水解速度,提高尿素的利用率,从而提高水稻产量。该研究阐述并总结了脲酶抑制剂的作用机制及其在水稻增产中的应用现状。

Urea plays a crucial role in improving the rice output,but the widely-distributed urease in soil will bring about the quick hydrolysis of urea,as a result,it will reduce the utilization of nitrogen for rice.The addition of urinary inhibitors can retard the hydrolysis progress of urea,increase the utilization of urea,thereby increasing the rice yields.This article expounded and summarized the mechanism of action of the urine inhibitor and its current application research in rice growing.
