粮食增产效果最显著的措施是施用化肥,但是当前我省的化肥状况是数量不足,比例失调,质量低下(指碳铵).多方面权衡,我们认为提高碳铵利用率,是投资少,见效快,增产粮食的重要途径.我省生产的氮肥品种,其中50%是碳铵.碳铵的最大缺点是利用率低,作物所得到的氮素远少于工业上所提供的数量.因此,在化肥品种不全,数量不足的情况下,提高碳铵利用 The most obvious measure to increase grain yield is to apply chemical fertilizers, but at present, the status of chemical fertilizers in our province is insufficient in quantity, imbalanced in quality and poor in quality (referring to ammonium bicarbonate). In many aspects, we think that increasing ammonium bicarbonate utilization is less investment and more effective Fast, and an important way to increase grain production.Our province produces a variety of nitrogenous fertilizers, of which 50% is ammonium bicarbonate.The biggest disadvantage of ammonium bicarbonate is the low utilization rate, and the crops are far less than the amount of available nitrogen in the industry to provide the quantity.Therefore, In incomplete fertilizer varieties, the number of cases, improve the utilization of ammonium bicarbonate
