There are 18 kinds of essential elements for plant growth. Except that carbon, hydrogen and oxygen can be exchanged by stomata, the other 14 elements are called as a large number of elements according to the amount needed for plant growth. Calcium, magnesium and sulfur are called as secondary elements, while iron, manganese, copper, zinc, chlorine, boron, molybdenum, cobalt and nickel are called trace elements. At present, the chemical fertilizers on the market are mainly to supplement a large number of nitrogen, phosphorus and potassium.
With the continuous progress of fertilizer technology, industrial structure change, agricultural knowledge progress and other factors, fertilizer products also change and adjust, from the beginning of single fertilizer to compound fertilizer development. With the continuous improvement of fertilizer equipment, NPK fertilizer production line is widely used. Single fertilizer refers to fertilizer products containing only one nutrient element, such as nitrogen, phosphorus or potassium, while compound fertilizer includes more than two kinds of nitrogen, phosphorus and potassium.
Advancement of fertilizer granulation production process
Fertilizer products tend to be commercialized, functional and diversified, and are selected by consumers according to crop cultivation period in a phased division of labor. The development of new and ecological fertilizers will inevitably become a trend, so the fertilizer products will continue to develop towards more advanced slow-release fertilizers, nutrients or microbial fertilizers in the future. Our factory has developed organic fertilizer granulator suitable for different raw materials, designed a variety of fertilizer granulation production processes, and promoted fertilizer production.
Every step of fertilizer application is closely linked, and each step has its own task. The addition of lime can alleviate the effect of acidified soil, at the same time, magnesium and calcium can also supplement secondary elements. The application of high P compound fertilizer and organic matter fertilizer in the base fertilizer period can improve the absorption effect of P fertilizer and promote the development of root system. Organic matter fertilizer can improve the fluffy degree of soil, provide space for root growth, and make plants robust. The use of chemical fertilizer with higher nitrogen fertilizer can supplement the nutrition of crop growth and leaf growth, and increase the accumulation of photosynthetic products. Panicle fertilizer can promote the development of panicle and the transformation of photosynthetic products into starch, which becomes the full capital of grain. In addition, the combination of water-soluble fertilizer and microbial fertilizer can improve the quality and income. Our specialized organic fertilizer production equipment processes special commercial fertilizer to meet various needs of crops.
