Scientific application method containing chlorinated fertilizer

Various crops are sensitive to chlorine. For crops that are sensitive to chlorine or weak in chlorine, there are mainly tobacco, sweet potato, tea, etc. The application of chlorinated fertilizers such as ammonium chloride and potassium chloride to these crops often affects product and quality. For example, too much chlorine will reduce the flammability of tobacco, and the smell is not good; the starch content of potato crops is degraded and the quality is poor; the sugar content of the fruit is lowered, and the acidity is high, so that the flavor of the fruit is not good. Therefore, chlorine-sensitive crops should be treated with sulphur-containing or non-chlorinated fertilizers.

On the contrary, crops that are not sensitive to chlorine or have strong chlorine resistance, such as sugar beet, spinach, millet, kenaf, radish, rice, cotton, sorghum, rape, cucumber, barley, etc., which use chlorinated fertilizer to save fertilizer Cost, and will receive good results. For example, the application of chlorinated fertilizer in rice fields can reduce the toxicity of hydrogen sulfide to rice roots, and the effect is often better than that of sulfur-containing fertilizers.

The crops with medium chlorine tolerance are mainly corn, peanuts, beans, tomatoes, eggplant, sugar cane, celery, Chinese cabbage, small rapeseed, strawberry, broccoli, etc. These crops can be applied with appropriate amount of chloride fertilizer.

Whether it can be applied with chlorinated fertilizer depends on the local rainwater and irrigation conditions, such as climate arid areas, soil salinization is more common, generally less or no application of chlorinated fertilizer. Large boron vegetable land has high salt content, closed management, and it is not suitable to apply chlorinated fertilizer. In areas with heavy rain or irrigation conditions, chlorinated fertilizers can be applied to the base fertilizer because chlorine in the soil is easily lost with water.
