Farmers in western Guangdong have the habit of using fertilizer as a fertilizer when they grow crops in winter. However, some people use the effect of good, fertilizer and increase production; and some people use not only no benefit, but also played a negative role The reason is whether there is any attention to scientific methods in use, because some fertilizers are not suitable for seed dressing, and others are used for application methods. First, fertilizers that have a corrosive effect on seeds should not be used as seed fertilizers. Ammonium bicarbonate is corrosive and volatile. It contains free sulfuric acid and carbonic acid for calcium phosphate. Both of them have strong corrosion effects on seeds, so they are not suitable for seed fertilizers. If it must be used as a seed fertilizer, contact with the seeds should be avoided. Ammonium bicarbonate can be applied under the sowing channel (holes), separated from the seed by a certain soil layer, or mixed with calcium superphosphate and earth-mixed fertilizers before application. Second, fertilizers containing chloride ions should not be used as seed fertilizers Potassium chloride, ammonium chloride and other chemical fertilizers contain chloride ions, and they produce water-soluble chlorides when applied to the soil, which is not good for seed germination and seedling growth. Potassium nitrate and other fertilizers contain nitrate ions and should not be used as seed dressing fertilizers.
