Abstract:
     The invention relates to a carbon-ammonium chemical fertilizer mixture using bentonite as filler for overcoming defects of short fertilizer efficiency of carbon-ammonium chemical fertilizer and easy loss. The montmorillonite crystal position of bentonite is more than 60%, its expansion multiple is more than 6 ml/g, grain size is 100-200 meshes and water content is less than 12%, and mixing ratio of carbon-ammonium and bentonite is 1.5-4 : 1. Said invention uses the water absorption, adsorption property and ion-exchange power of the bentonite to make azotification, prolong fertility and reduce loss of fertilizer efficiency, and at the same time, it also can implement soil moisture conservation and introduce trace elements.
