How to use chlorine-containing compound fertilizer? Please introduce the method of chlorine-containing compound fertilizer: potassium source comes from potassium chloride, nitrogen source is part or all of ammonium chloride compound fertilizer. Chlorine is one of the necessary nutrient elements for crop growth, but improper application will adversely affect crop growth. The main reasons are: first, because chloride ion makes one of the most active anions in the soil, it combines with cations to form chloride, which is easy to dissolve in the soil and can rise to the surface with soil water. The water evaporates and the salt remains on the surface. Bring the cations from the lower layer to the upper layer to aggravate the salt damage of the soil. Second, chloride ions can also combine with other cations to form harmful chlorides, such as calcium chloride in the calcareous soil of our city, which is disadvantageous to the growth and development of crops. Third, some plants are very sensitive to chloride ion, when the amount of absorption reaches a certain extent, it will significantly affect the yield and quality, usually called chlorine taboo crops. The use of chlorine-containing compound fertilizer should be paid attention to: first, it is widely used in crops with strong and medium chlorine tolerance. The main crops with strong chlorine tolerance in our city are cotton, spinach, sugar beet, cauliflower, tomato, rape, water radish, cucumber, eggplant, etc.; crops with medium chlorine tolerance are wheat, corn, peanuts, soybeans, onions, cauliflower, cabbage, celery, strawberries, grape seedlings, Hawthorn seedlings and so on. Second, it is not suitable to be used in crops with low chlorine tolerance. Mainly tobacco, sweet potato, potato, cabbage, chili, lettuce, amaranth, apple, grape, tea, watermelon and so on, these crops are usually called chlorine taboo crops; third, it is not suitable to apply in saline soil with high chlorine content, salinized soil, waterlogging depression with poor water permeability, calcareous soil with strong percolation and soil under greenhouse conditions for many years.
