With sustained and healthy economic growth, urban and rural residents' income and urbanization progress, the people's living standards continue to improve, and dietary structure gradually improves, the demand for aquatic products is at an increasing trend year by year, and the demand for aquatic products with good quality and high price is also growing, which directly promotes the rapid development of aquaculture industry. At present, China's aquaculture area is about 7036.11 thousand hectares, about 105 million mu. Aquaculture grew from 47.932 million tons in 2016 to 52.242 million tons in 2020, a compound annual growth rate of 2.18%, and is expected to further grow to 56.3 million tons in 2022. In recent years, ammonium bicarbonate has been widely used in fishery production, and has become an irreplaceable quick-acting nitrogen fertilizer in aquaculture. The specific performance is as follows:
Ammonium bicarbonate can increase nitrogen for phytoplankton in water and promote the proliferation of phytoplankton. When applied to farms or fisheries, it has played a positive role in promoting the growth of algae in water, especially after the decomposition of ammonium carbide, the increase of co2 content in water has an obvious role in the formation of dry matter of algae.
Ammonium bicarbonate can be decomposed into NH3, co2 and H2O, three gases, so it is also called gas fertilizer. It does not produce harmful intermediate products and final products after decomposition, and can be used for a long time in soil and water. Used together with phosphate fertilizer to form ammonium phosphate, fixed, can promote the absorption of phosphate fertilizer by algae. General application ratio: ammonium carbide 5-10 kg/mu, superphosphate 0.5-1 kg/mu (the actual amount depends on water quality conditions).
Compared with other nitrogen fertilizer products, the price of ammonium carbide is much lower, but the effect is very significant. Ammonia nitrogen fertilizer is one of the most easily absorbed forms of plants and algae. Although it is easily lost with water in soil, it has many benefits in fishery production.
Although ammonium bicarbonate has many advantages in aquaculture, excessive and improper application will cause rapid deterioration of water bodies, resulting in large-scale pollution, increased ammonia nitrogen, low PH value, and too high nitrite, which will lead to slow growth and even death of fish and shellfish. It is recommended to apply reasonably according to the water quality conditions and the guidance of the local agricultural technology department.
Shandong Desenlai Chemical currently has ammonium bicarbonate packaging specifications of 50kg/1000kg, customers can flexibly choose according to demand. In addition, part of the newly planned ammonium bicarbonate capacity of Hualu Hengsheng Jingzhou base is expected to be put into operation in recent years. After Jingzhou base is put into operation, Hualu Hengsheng ammonium bicarbonate will form a north-south supply pattern, welcome customers to consult and cooperate.
