采用小区试验方法，研究了不同肥料添加钼肥降低蔬菜硝酸盐积累的作用。结果表明，添加钼肥能够明显降低蔬菜硝酸盐积累，施肥后两周采收的蔬菜，硝酸盐含量更低。 Community test methods were used to study the effects of different fertilizers on the accumulation of nitrate in vegetables. The results showed that the addition of molybdenum fertilizer could significantly reduce the accumulation of nitrate in vegetables. The content of nitrate and nitrate in vegetables and fruits harvested two weeks after fertilization was lower.
