摘　　要：为提高蔬菜品质,并有效控制蔬菜中硝酸盐的积累,通过田间小区试验,研究了红菜园土和冲积菜园土条件下喷施稀土、铜肥、钼肥、锌肥、锰肥、硼肥后小白菜硝酸盐和亚硝酸盐含量的变化及对其他品质的影响.结果表明:喷施钼肥和锰肥降低蔬菜硝酸盐含量效果最佳,也显著增强了硝酸盐还原酶的活性.This paper is an attempt to study the effects of spraying rare earth element and micronutrient fertilizers on nitrate contents and quality in Chinese cabbage vegetables with a plot test in two vegetable soils.The results show that spraying molybdenum fertilizer and manganese fertilizer can decrease nitrate contents in Chinese cabbage significantly.Molybdenum fertilizer and manganese fertilizer also increase nitrate reductase activity.

关 键 词：蔬菜 稀土 微肥 硝酸盐
