摘要
氮肥增效技术 (剂 )添加到氮肥及含氮肥料的生产中成为长效肥料。长效肥料在土壤中对转化氮素的脲酶、硝化(亚 )细菌活性具有抑制活性作用 ,对NH4+和NO3 -离子有稳定功效作用 ,从而达到氮肥增效、长效效果。长效肥料在农业生产中使用方便、成本低又能保护生态环境 ;提高氮素利用率8%— 12 %、提高长效专用肥利用率 17%— 2 5 % ,工业化生产降低氮肥长效成本达 6 6 %。为我国农业生产开发适合应用的低成本长效氮肥及专用肥探索出一条行之有效的途径。
Technique (agent) for increasing effect of nitrogen fertilizer will been added to nitrogen fertilizer to make slow release fertilizers (SRF), The action of SRF could inhibitor the activity of unease, nitrification bacteria in order to stabilize ammonium. The SRF had the characteristics of slow release effects, convenience, low cost, environment friendly. The SRF could increase the recovery rate of nitrogen fertilizer by 8%-12%, the production of SRF had been reduced by 66% of cost.
