Application of chlorinated fertilizers

Containing chlorinated fertilizer refers to a class of chemical fertilizers containing chloride ions, such as ammonium chloride and potassium chloride, as well as complex (mixed) Hefei, special fertilizers, and formula fertilizers prepared from ammonium chloride and potassium chloride as raw materials. . Improper use can cause “chlorinating” phenomena such as seed burning and injury, and should pay attention to the following aspects in specific application: 1. Chloride-containing fertilizers should be applied preferentially to crops with strong chlorine or moderate chlorine tolerance, such as rice, wheat, rape, spinach, radish, beans, and tomatoes; crops with low chlorine tolerance, such as tobacco, tea, lettuce, Citrus, grape, etc., generally do not apply or strictly control the dosage. ??2. Suitable for use in rainy seasons or in areas with high precipitation, dry lands without irrigation, poorly drained saline-alkali lands and high-temperature and dry seasons, and areas with low water and rainfall, preferably with or without chlorinated fertilizers. ??3. In the application of chlorinated fertilizers, combined with the application of decomposed organic fertilizer, can increase the fertilization of chlorinated fertilizers, reduce the negative effects of chloride ions. ??4. With chlorinated fertilizer can be used as base fertilizer or top dressing, not suitable for seed fertilizer. Used in the middle and later stages of crop growth, should be used sparingly or not at the seedling stage.
