碳酸氢铵又名重碳酸铵,其分子式为 NH_4HCO_3,是一种白色结晶的微碱性肥料,理论合氮量为17.7%。自1958年我国首创以来,至今已是国内主要的氮肥品种之一,约占全国氮肥产量的50%左右,特别是小氮肥厂,几乎全部生产该产品。目前,在我国化肥品种构成比例中,碳酸氢铵最高,1978年为34.02%,并在全国各地被广泛采用。实践证明,长期施用碳酸氢铵不会像硫酸铵、氯化铵那样留下酸根,给土壤带来不良影响,相反,因其含有碳酸根,
Ammonium bicarbonate, also known as heavy ammonium bicarbonate, its formula is NH_4HCO_3, is a white crystalline slightly alkaline fertilizer, the theoretical combined amount of 17.7% nitrogen. Since China’s first creation in 1958, it has become one of the major nitrogenous fertilizer varieties in China so far, accounting for about 50% of the total nitrogenous fertilizer production in China. In particular, the small nitrogenous fertilizer plant produces almost all of the products. At present, among the proportions of fertilizer varieties in China, ammonium bicarbonate is the highest, 34.02% in 1978, and is widely used all over the country. Practice has proved that long-term use of ammonium bicarbonate does not like ammonium sulfate, ammonium chloride leaving acid roots, to the soil adversely affected, on the contrary, because it contains carbonate,
