碳酸氢铵(NH4HCO3)是我国20世纪50年代独创的一个主要氮肥品种,在农业生产中发挥了巨大作用。碳铵的不足是含氮量较低和常温下易分解;但其优点是入土后易被土粒吸持和作物根系吸收。因而碳铵对作物的田间肥效与尿素、硫铵等其他氮肥相当。因此,只要在使用时扬长避短,就能继续充分发挥其作用。 Ammonium bicarbonate (NH4HCO3) is one of the main nitrogenous fertilizers cultivated in China in the 1950s and has played an important role in agricultural production. The disadvantage of ammonium bicarbonate is low nitrogen content and easy decomposition at room temperature; however, its advantage is that it is easy to be absorbed by soil particles and absorbed by crop roots after it is buried. Thus ammonium bicarbonate on the crop field fertilizer and urea, ammonium sulfate and other nitrogen fertilizer quite. Therefore, as long as the use of avoid weaknesses, we can continue to give full play to its role.
