Four types of fertilizers cannot be used as seed fertilizers
The corrosive fertilizer ammonium bicarbonate is volatile and corrosive, and it is easy to smoke seeds and seedlings. Calcium superphosphate contains free sulfuric acid and phosphoric acid, which will cause damage to seed germination and seedling growth. Generally, it is not suitable for seed fertilizer. The poisonous fertilizer urea often produces a small amount of biacid during the growth of the crop. If the content of the biacid exceeds 20%, it will cause poison to the seeds and seedlings. In addition, urea molecules with a high nitrogen content penetrate into the protein molecules of the seed, denature the protein, and cause germination and seedling poisoning. Fertilizers containing chloride ions and other fertilizers containing chloride ions, such as potassium chloride, will produce water-soluble chlorides when applied to the soil, which is not good for seed germination and seedling growth, and is easy to burn seeds and burn seedlings. Nitrate ions contained in fertilizers such as ammonium nitrate and potassium nitrate can have toxic effects on seed germination. Unfermented farm manure is commonly used in the countryside as manure, human waste, urine and other fertilizers. If unfermented, a large amount of heat energy is released during the fermentation process, which can easily burn the root system and release ammonia to burn the seedlings. Therefore, do not apply the unfermented organic fertilizer, and only after the high temperature fermentation of the dumplings, fully fermented can be used as seed fertilizer.
