【摘要】 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。更多还原

【Abstract】 Ammonium bicarbonate(NH4HCO3)is a main kind of nitrogen fertilizer originally created during the 1950s in China,it plays a huge role in the agricultural production.The shortage of NH4HCO3 is lower N content and easier to decomposition in normal temperature,but the advantage is easier to be absorbed by the soil particles and to be up taken by crop’s roots when it is applied into soil.Therefore the field fertilizer effect of ammonium bicarbonate is equal compared with other nitrogen fertilizer such as urea,ammonium sulfur etc.So,as long as making best use of the advantages and avoiding the disadvantages when using it,ammonium bicarbonate will continue playing the important role.更多还原
