解放以来,随着农业生产和化学工业的发展,化学肥料的用量逐年增加,对提高农作物产量起了重大的作用。农业生产实践和試驗研究证明,各种化学肥料中以氮肥的增产效果最大,需要量也最多。特别是水稻,施用氮肥的增产效果更为明显。这就是硫酸銨为农民所喜爱的原因。 Since the liberation, with the development of agricultural production and chemical industry, the amount of chemical fertilizers increased year by year, which has played a significant role in improving the crop yield. Agricultural practices and experimental studies have shown that various types of chemical fertilizers have the largest yield-increasing effect of nitrogenous fertilizers and the most required quantities. Especially rice, the effect of nitrogen fertilizer application is more obvious. This is why ammonium sulfate is favored by farmers.
