硝化作用是农田氮素转化的主要途径,与氮素损失和利用有非常密切的关系。维持氮素以NH-_4~+的形式存在是提高作物氮素利用率的关键之一。由于合成硝化抑制剂价格昂贵,在不同土壤类型中性能不稳定,而且存在生态环境和食品的安全隐患等,开发植物源的生物硝化抑制剂(BNIs)显得十分必要。迄今为止,BNIs只从Brachiaria humidicola和高粱中报道过。 Nitrification is the main way of nitrogen transformation in farmland, which is closely related to the loss and utilization of nitrogen. Maintaining nitrogen in the form of NH-4 ~ + is one of the keys to improve crop nitrogen utilization. It is necessary to develop plant-derived biological nitrification inhibitors (BNIs) due to the high cost of synthetic nitrification inhibitors, unstable performance in different soil types, and the potential safety hazards of the environment and food. To date, BNIs have only been reported from Brachiaria humidicola and sorghum.
