摘　　要：以小白菜为试材,通过温室盆栽试验,研究了喷施不同的叶面微肥对小白菜叶绿素含量、叶片数、产量、维生素C含量、还原糖含量以及硝酸盐含量的影响。结果表明:喷施叶面微肥促进了小白菜叶片数的增加,叶绿素含量的提高及产量的增加,且改善了小白菜品质,表现为叶片维生素C含量和还原糖含量的显著增加以及硝酸盐含量的降低;综合考虑,喷施叶面微肥B(200倍)的效果最优,更有利于小白菜农艺性状和品质的提高。Taking pakchoi as materials,the greenhouse pot experiment was conducted to investigate the effects of spraying different trace-element foliar fertilizers on the chlorophyll content, leaves number, yield, VC content, reducing sugar content and nitrate content. The results showed that, spraying trace-element fertilizers not only increased the number of leaves,chlorophyll content and yield, but also improved the quality including Vitamin C content, reducing sugar and nitrate content. The conclusion suggested that spraying trace-element foliar fertilizer B （200 times） was more conducive to improving the agronomic and quality of pakchoi.
