碳酸氢铵(简称碳铵)生产简便,投资少,成本低,适于各地建厂,大量生产。我区一九六六年卽建成碳铵化肥厂,生产的碳铵含氮量17％。但碳铵挥发性大,(?)吸收空气中的水分而分解,在36℃的气温下就大量挥发氨气,如果施用不当,肥效损失很大。为此,必须研究其施用技术,明确其增产效果,为大面积推广提供依据。 一、碳铵的肥效 一九六八年在乌鲁木齐县工农兵公社工农兵大队和星火大队多点试验结果,冬麦追施等氮量碳铵(含氮17％)和硝铵(含氮34％),肥效相近,或碳铵略高于硝铵。以每斤氮素增产数比较,碳铵为12.47斤,硝
Ammonium bicarbonate (referred to as ammonium bicarbonate) production is simple, low investment, low cost, suitable for construction around the plant, mass production. In 1966, our district built an ammonium bicarbonate fertilizer plant, producing 17% of ammonium bicarbonate. However, ammonium bicarbonate is volatile and (?) Absorbs moisture in the air and decomposes. A large amount of ammonia gas is volatilized at a temperature of 36C. If applied improperly, the fertilizer efficiency is greatly reduced. To this end, we must study the application of technology to clarify the effect of increasing production, provide a basis for large-scale promotion. First, ammonium bicarbonate fertilizer effect In 1968 in Urumqi Gongnongbing commune workers and peasant soldiers Brigade and Star Brigade more test results, winter wheat topdressing and other nitrogen ammonium bicarbonate (17% nitrogen) and ammonium nitrate (nitrogen 34 %), Similar fertilizer, or ammonium bicarbonate slightly higher than ammonium nitrate. Nitrogen per kilogram yield increase compared to 12.47 kg of ammonium bicarbonate, nitrate
