Chlorine-based compound fertilizer refers to a chlorine-containing compound fertilizer prepared by processing potassium chloride and ammonium chloride as a potassium source. The sulfur-based compound fertilizer is a compound fertilizer prepared by using potassium sulfate as a potassium source or potassium chloride to remove chloride ions. The specific differences between chlorine-based compound fertilizer and sulfur-based compound fertilizer are as follows:
1. Different composition: The sulfur-based compound fertilizer has low chlorine content, the national standard is less than 3%, and contains a large amount of sulfur, which can effectively improve the symptoms of soil sulfur deficiency; while the chlorine-based compound fertilizer contains a lot of chlorine, which is bad for some crops. influences.
2, the process is different: the sulfur-based compound fertilizer has a very low chloride ion content, and the chloride ion is removed during the production process; while the chlorine-based compound fertilizer does not remove the chlorine element harmful to the chlorine-free crop during the production process, so the product contains a large amount of chlorine.
3, the scope of application is different: chlorine-based compound fertilizer has adverse effects on the yield and quality of the avoidance of chlorine crops, seriously reducing the economic benefits of such economic crops; and sulfur-based compound fertilizer is suitable for all kinds of soils and various crops, and can Effectively improve the appearance and quality of various economic crops, can significantly improve the grade of agricultural products.
4. Different application methods: Chlorine-based compound fertilizer can be used as base fertilizer and top dressing. It is not suitable for seed fertilizer. When used as base fertilizer, it should be mixed with organic fertilizer and phosphate rock powder in neutral and acidic soil. It should be applied early for topdressing. The sulfur-based compound fertilizer can be used as base fertilizer, top dressing, seed fertilizer and top dressing.
So which kind of fertilizer application effect is good? Nowadays, many farmers’ friends are affected by advertising and they all think that the sulfur base is good. This is not true.
1. For economic crops, especially for vegetables that require more sulfur, such as onions, leeks, garlic, etc., or sulfur-based compound fertilizers that are sensitive to sulfur deficiency, sugar cane, peanuts, soybeans and kidney beans, but The application of chlorine-based compound fertilizers on aquatic vegetables and hemp crops is better because chloride ions are essential for hemp crops, which promote fiber development and enhance fiber resilience.
2. For field crops, such as corn, rice, soybeans, wheat and other crops, the fertilizer efficiency of the two types of compound fertilizers is the same, no difference. The compound fertilizer with potassium sulphate as raw material is very expensive, because the price of potassium sulphate is too high, so it is not necessary to use sulphur-based compound fertilizer on field crops, and it is not cost-effective.
3. For the use of chlorine-based compound fertilizer, it should be divided into hi-chlorine crops according to the sensitivity of crops to chloride ions: coconut, onion, spinach, celery, cabbage, etc.; crops with strong chlorine tolerance: beet, rice, millet, Sorghum, barley, wheat, corn, eggplant, peas, chrysanthemum, etc.; medium-to-chlorine crops are: cotton, soybean, rapeseed, tomato, citrus, grape, tea, onion, radish, etc.; chlorine crops are: lettuce, green beans , tobacco, yam, etc.
