碳酸氢铰（简称碳铵）是我国生产最多的一种氮肥，在旱作区，碳铵被广泛用作基肥，收效良好。但因其易结块、常温下易挥发的特性，致使施用困难，施用不当会造成肥料的严重浪费。因而，农业生产中如何用好碳铰是合理施肥的一项重要课题。为利用常规的耧追法施用碳铵，并达到良 Bicarbonate hinge (referred to as ammonium bicarbonate) is China’s largest production of a nitrogen fertilizer, in the dry area, ammonium bicarbonate is widely used as a base fertilizer, with good results. But because of its easy caking, volatile properties at room temperature, resulting in application difficulties, improper application will cause serious waste of fertilizers. Therefore, how to make good use of carbon hinge in agricultural production is an important issue of rational fertilization. Ammonium bicarbonate was used to achieve good performance using conventional methodologies
