碳酸氢铵是我国的重要氮肥品种。它具有生产流程简单,投资少,成本低的特点,作为肥料施进土壤后除供给作物氮素外,在分解过程中释放出的二氧化碳还可加强作物的光合作用。但是该肥料性质不够稳定,容易吸湿结块,而且易于挥发分解,随着温度和湿度的增加挥发损失越大。在气温19℃湿度72％条件下,肥料暴露一天,氮素损失11.2％,三天损失32.1％;在气温24℃,湿度78％条件下,肥料暴露一天,氮素损失26.7％,三天损
Ammonium bicarbonate is an important nitrogenous fertilizer species in our country. It has the characteristics of simple production process, less investment and low cost. In addition to supplying crop nitrogen after being applied into the soil as fertilizer, the carbon dioxide released in the decomposition process can also enhance the photosynthesis of crops. However, the fertilizer is not stable enough in nature, it is hygroscopic and agglomerated, and is prone to volatilization and decomposition, with the greater the loss of volatility with increasing temperature and humidity. Nitrogen loss was 11.2% and 32.1% in three days when the temperature was 19 ℃ and humidity was 72%. One day fertilizer exposure, 24.7% nitrogen loss and three days loss
