目前,各地农村社队在土法生产腐植酸肥料时,普遍采用直接氨化法,即在泥煤或风化煤中加入一定量的碳铵(碳酸氢铵)水液或氨冰,拌匀堆积氨化几天后施用。这个方法操作简便,易于推广,但在生产操作和堆积氨化过程中“跑氨”厉害,氨味呛人,尤其在露天堆积,日晒雨淋,氮素损失更为严重,如建阳地区农科所,将碳铵25斤,泥煤
At present, the rural communes and brigades in the local production of humic acid fertilizer, the widespread use of direct ammoniation, that is, peat or weathered coal by adding a certain amount of ammonium bicarbonate (ammonium bicarbonate) liquid or ammonia ice, mix well A few days after the amination. This method is easy to operate and easy to popularize. However, during the production operation and stacking amination process, “run ammonia” is very powerful and the ammonia smell is choking. In particular, it accumulates in the open air, exposing to the sun and rain and the nitrogen loss is even more serious. Agricultural Institute, the ammonium bicarbonate 25 pounds, peat
