The organic fertilizer is applied to the organic fertilizer vegetable field, and the organic colloid is formed during the decomposition process, and the organic colloid has a strong adsorption capacity for the cation. When the chemical fertilizer is applied to the soil, the cation is mostly adsorbed by the colloid, so the soil solution is The relative amount is reduced, so that the concentration of the soil solution does not rise too high, which can increase the buffering capacity of soil nutrients and greatly reduce the possibility of fertilizer damage.
Reasonable fertilization The application of chemical fertilizers in vegetable fields must be applied in limited quantities and at the specified concentrations, and the fertilizers will be greatly reduced. Generally, ammonium carbonate should not exceed 30 kg per acre, ammonium sulfate should not exceed 20 kg, and urea should not exceed 10 kg.
Uniform fertilization When applying fertilizer, the vegetable field must be applied in layers and deep in the whole layer to achieve soil and fertilizer fusion, so that the fertilizer is evenly distributed throughout the tillage layer. At the same time pay attention to fertilization should be properly watered, keep the soil moist, reduce the concentration of the solution, and not cause fat damage.
