- 摘要:
- 肥料添加剂NAM (由脲酶抑制剂和硝化抑制剂等成分组成)是一种新型肥料增效剂,为使其有效利用,通过小区试验,研究了NAM对寒地水稻产量、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水稻产量、氮肥利用率和经济效益。等养分情况下应用NAM肥料添加剂能够促使水稻增产,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.It is a new type of fertilizer synergistic agent.Effects of urea combined with NAM on rice yield,fertilizer N use efficiency and economic benefits were studied.The results showed that the NAM could increase the yield of rice.The fertilizer N use efficiency and economic benefits of rice improved by using the NAM.When decreasing the fertilizer N by 20%,the yield of rice increased by using the NAM.The use of NAM fertilizer additive is an effective measure to realize fertilizer reduction
