- 摘要:
- 为了促进NAM的推广应用，通过小区试验，研究了肥料添加剂NAM (由脲酶抑制剂和硝化抑制剂等成分组成) 对寒地玉米产量、氮肥利用率以及经济效益的影响。结果表明：与常规施氮处理相比，应用NAM肥料添加剂能够提高玉米产量、氮肥利用率和经济效益。在减少20%氮肥用量的情况下应用NAM肥料添加剂处理的玉米未减产，说明应用NAM肥料添加剂是实现化肥减量的有效措施。
- Abstract:
- NAM is a kind of fertilizer additive made of the urease inhibitor，nitrification inhibitor and other components．In order to promote the application of NAM， the effects of urea combined with NAM on maize yield and fertilizer N use efficiency and economic benefits were studied.The results showed that NAM could increase the yield of maize.The fertilizer N use efficiency and economic benefits of maize improved when using the NAM.When decreasing the fertilizer N by 20%,the yield of maize increased by using the NAM.Using the NAM is the good way to reduce the fertilizer.
