目前，我国市售的含氯化肥有氯化铵（NH4Cl）和氨化钾（KCl）．它们都是含氯速效化肥。这两种含氯化肥约占工业化肥总产量的15～20％，在农业中施用比较普遍，对农作物的增产发挥了巨大作用。不过，有些人缺乏施用化学肥料的科学常识，不懂得不同农作物对化肥有不同要求，滥施 At present, ammonium chloride (NH4Cl) and potassium chloride (KCl) are commercially available in our country. They are all chlorinated fast-acting fertilizers. These two types of chlorinated fertilizers account for about 15-20% of the total output of industrial fertilizers and are more commonly used in agriculture and have played a significant role in increasing crop production. However, some people lack the scientific common sense of applying chemical fertilizers and do not know how different crops require different fertilizers
