Cauliflower uses fertilizer types. In the production of non-polluting broccoli, the fertilizers allowed for cauliflower are basically divided into four categories: (1) Organic fertilizer: including human and animal manure, compost, manure, biogas fertilizer, green manure, crop straw, mud fertilizer, cake fertilizer, grass ash, slag, etc. Except for grass ash and slag, the rest should be thoroughly cooked before application. (After high-temperature fermentation, organic manure can kill 100% of pathogenic microorganisms such as E. coli, and can reduce the volume and weight by 1/2-1/3, which is convenient for field transportation. In addition, the organic manure is not cooked until it is applied to the field. Fermentation, easy to burn the roots.) (2) Biological bacterial fertilizer: including humic acid fertilizers, rhizobia fertilizers, phosphorus bacteria fertilizers, composite microbial fertilizers. (3) Inorganic fertilizers: such as ammonium sulfate, urea, superphosphate, potassium sulfate, etc., which contain neither chlorine nor nitrate nitrogen, nitrogen fertilizers, and broccoli fertilizers produced locally. (4) Trace Element Fertilizers: Fertilizers mainly formulated with trace elements such as copper, iron, boron, zinc, molybdenum, and beneficial elements. The general principle of broccoli formula fertilization is based on the need for fertilization during growth, what nutrients are missing, what fertilizers are applied; how much is lacking, and how much fertiliser is applied; broccoli formula fertilization techniques should be promoted throughout the country and broccoli-specific fertilizers should be promoted. This will not only harmonize the supply and demand of nutrients between soil and crops, reduce waste caused by excessive nitrogen fertilization, but also avoid phosphorus enrichment and excessive potassium consumption in the soil, which will help maintain soil nutrient balance and improve soil fertility. , laying the foundation for sustainable development of cauliflower production.
