What issues should be noted when applying microbial fertilizers:
1. How to apply nitrogen-fixing bacteria fertilizer in the field?
There are many types of nitrogen-fixing bacteria, and round nitrogen-fixing bacteria can be used in a variety of crops. The combined nitrogen-fixing bacteria have strong selectivity for crops. Therefore, depending on the conditions of different crops, the application methods are also different.
(1) Accompanying species: Mix the nitrogen-fixing bacteria agent with a small amount of sticky silk water and the seeds, and then apply it in the shade.
(2) Ditch application: In order to make the nitrogen-fixing bacteria settle well in the vicinity of the root system, the fungicide used per acre can be 15-25g with superphosphate, 1.5-2.5kg of water, and 10-20kg dry. The soil is mixed well and becomes a moist small soil mass, which is applied to the ditch together with the seed. This method is suitable for cotton, corn, wheat and other food crops.
(3) Acupoint application: The nitrogen-fixing bacteria agent is mixed with the weathered coal, the plant ash or the decomposed organic fertilizer, and then made into granules, which can also be applied to the planting hole when the crop is planted. This method is suitable for melons and vegetables, such as watermelon, melon, hazelnut, tomato, cucumber, sweet pepper and so on.
(4) Roots: When rice, sweet potatoes, etc. are transplanted, the bacteria are infiltrated with water. Vegetables and tobacco use 50-100 grams per acre.
(5) used as top dressing: it can be directly applied to granules, or it can be mixed with manure cake fertilizer and applied to the roots of plants, but not with a large amount of chemical fertilizers, especially ammonia nitrogen fertilizers (urea, ammonium bicarbonate, chlorination). Ammonium, ammonium sulfate) is applied in combination. So as not to damage the role of foreign nationality of nitrogen fixation. When applying, the fertilizer or organic fertilizer may be mixed and applied to the soil, and then the fertilizer is applied.
