Having measured the effectiveness of atmospheric N. fixation the macro- or micro-symbionts as well as agronomic factors can be manipulated with the objective to maximize biological nitrogen fixation. A suitable method to quantify nitrogen fixation is therefore necessary in any programme aiming a作者: 飲料 時(shí)間: 2025-3-22 15:24 作者: 飲料 時(shí)間: 2025-3-22 20:17

Response to inoculation and N fertilization for increased yield and biological nitrogen fixation oflow numbers, inoculation contributed substantially to increased N. fixation traits and yield. Both foliar and soil methods inhibited nodulation at high N rates and did not significantly increase bean yield, when comparing low (10 kg N ha.) and high (50 kg N ha .) rates applied after emergence.
