Compound microbial fertilizer equipment Henan Viet fertilizer equipment manufacturing company developing new compound microbial fertilizer equipment first, by the impact of the new normal economy, traditional fertilizer industry overcapacity exacerbate the problem, the new fertilizer industry development speed; the second is influenced by many factors, resulting fertilizer decline in corporate profits, the urea solution irrigation equipment prices, some SMEs development difficulties; Third, with the pace of nation-building and promoting ecological civilization "organic industry," the rapid development of the urea solution irrigation equipment and technology, the chemical class of the new fertilizer market are subject to different impact, and organic fertilizer, fertilizer, etc. The rapid development of new fertilizers; four new fertilizer industry is the concept of speculation, but the problem in time for the fashion light weight, the effect is still severe, the industry's mutual belittle, to suppress is widespread; five is encouraged by the State land transfer policies, the emergence of grower, family farms, farmers' cooperatives, farms and other large-scale production of Reclamation organization, the new fertilizer products market purchases of scale, intensive trend accelerate, it will propose new fertilizer manufacturer quality, brand, service higher requirements. The use of the fertilizer ammonium sulfate fertilizer equipment Henan Viet equipment research and development company manufacturing ammonium sulfate fertilizer equipment Ammonia and sulfuric acid neutralization directly derived reaction, the urea solution irrigation equipment and technology, used much, the main use of industrial by-products absorption or emission of waste gas with sulfuric acid or ammonia (such as coke oven gas sulfate absorption of ammonia, ammonia absorption smelter flue gas sulfur dioxide, kapron production of ammonia or sulfuric acid process titanium dioxide production sulfuric acid waste). There is also legal Ammonium gypsum (natural gypsum or phosphogypsum, ammonia, carbon dioxide as a raw material). Not with other alkaline fertilizer or basic physical contact or mixed application to prevent reduce fertility. (2) should not be long-term application of ammonium sulfate, urea solution irrigation equipment on the same piece of arable land, or cause soil compaction become acid. When administered if it proves necessary, it may be appropriate with the application of lime or organic fertilizer. But we must be careful not to mix and lime application to prevent the decomposition of ammonium sulfate, causing nitrogen losses. Both with the general administration to be separated by 3 to 5 days. (3) suitable for application in acidic soils. Ammonium hydroxide, and sulfuric acid, the crystallization, centrifugation and drying derived.
