1) | Nitrogen-fixing bacteria are mesophilic bacteria, the most suitable growth temperature is 25~30℃, |
2) | Nitrogen-fixing bacteria can fully exert nitrogen-fixing effect only in the environment that is rich in carbohydrates but lacks compound nitrogen. When the carbon-nitrogen ratio in the soil is lower than 40-70:1, nitrogen fixation stops rapidly. Appropriate carbon-nitrogen ratio in soil is the most important condition for nitrogen-fixing bacteria to develop into dominant bacteria and fix nitrogen. Therefore, nitrogen-fixing bacteria are best applied on soils rich in organic matter, or in combination with organic fertilizers. |
3) | After a large amount of nitrogen fertilizer is applied to the soil, nitrogen-fixing bacteria fertilizer should be applied every 10 days, otherwise the nitrogen-fixing ability of nitrogen-fixing bacteria will be reduced. However, nitrogen-fixing bacteria can be used in combination with phosphorus, potassium and trace element fertilizers to promote the activity of nitrogen-fixing bacteria, especially on poor soils. |
4) | Nitrogen-fixing bacterial fertilizer is suitable for various crops, especially for grass crops and leafy vegetables in vegetables. Nitrogen-fixing bacterial fertilizer is generally used for seed dressing, and it is mixed with sowing, and then covered with soil to avoid direct sunlight. It can also be dipped in seedling roots or applied as base fertilizer on vegetable seedbeds, or mixed with cotton cover seed fertilizer. It can also be applied to the roots of crops, or combined with irrigation. |
