联合固氮菌在根际土壤的特殊生境中,表现出与根际土壤理化性质密切相关的固氮特性,但由于联合固氮菌对环境中的速效氮极为敏感,因此其固定氮的量保持在一个很低的水平。添加肌醇六磷酸能极大提高其固氮活力,提高抗铵阻阈值,取得高质量的增产节氮效果。
The combination of azotobacter in the rhizospheric soil in a special habitat, rhizosphere soil showed physical and chemical properties closely related to the nitrogen fixation characteristics, but due to nitrogen and nitrogen bacteria are extremely sensitive to the available nitrogen in the environment, so the amount of fixed nitrogen maintained at a very Low level. Adding phytic acid can greatly increase its nitrogen-fixing activity, improve the anti-ammonium resistance threshold and achieve high-quality nitrogen-yield increasing effect.
