- 摘要:
- 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) 对寒地大豆生育性状、产量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大豆产量、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肥料添加剂处理的大豆未减产，NAM肥料添加剂是实现化肥减量、缓解大豆连作障碍的有效措施。
- Abstract:
- NAM is a kind of fertilizer additive made of the urease inhibitor，nitrification inhibitor and other components．The effects of urea combined with NAM on soybean yield and fertilizer N use efficiency and economic benefits were studied.The results showed that the NAM could increase the yield of soybean.The fertilizer N use efficiency and economic benefits of soybean improved when using the NAM.When decreasing the fertilizer N by 30%,the yield of soybean increased by using the NAM.Using the NAM is the good way to reduce the fertilizer.
