氨化过石是把过石和碳酸氢氨混合经过沤制成为含氮、磷两种元素的复合肥料。为了研究和摸索氨化过石不同施用方法对甜菜产量、含糖量的影响,故进行了此项试验。一、氨化过石的配制首先把碳酸氢铵用冷水化成糊状,然后掺入过石粉,搅拌均匀,后用塑料密封,氨化七天。过石和碳酸氢铵的比例为4:1。 Ammoniated stone is the stone and ammonia bicarbonate mixed through 沤 made of nitrogen, phosphorus, two kinds of compound fertilizer. In order to study and explore the different methods of ammoniation stone over the beet yield, the impact of sugar content, so the test was carried out. First, the preparation of ammoniated stone First, ammonium bicarbonate with cold water into a paste, then mixed with stone powder, stir, then sealed with plastic, ammoniation for seven days. Stone and ammonium bicarbonate ratio of 4: 1.
