常用的含氯肥料有氯化铵 (含 Cl 66.3% ) ,氯化钾 (含 Cl 47.5 % )。氯元素少则有益 ,多则有害 ,所以正确施用含氯化肥 ,对于提高化肥施用效果有重要意义。氯在作物营养平衡中的主要作用是参与光合作用 ,调节植物细胞渗透压 ,并影响作物对氮、磷、钾、钙、镁和硅的吸收 ,增强作 Common chlorine-containing fertilizers are ammonium chloride (Cl 66.3%), potassium chloride (Cl 47.5%). Chlorine is beneficial at least, as many harmful, so the correct application of chlorine-containing fertilizers, for improving the effect of chemical fertilizer is of great significance. The main role of chlorine in crop nutrient balance is to participate in photosynthesis, regulate plant cell osmotic pressure and affect crop uptake of nitrogen, phosphorus, potassium, calcium, magnesium and silicon,
