摘　　要：研究了微肥对尖叶菠菜硝酸盐积累的拮抗效应,结果表明:微肥配合尿素施用与单施尿素相比,尖叶菠菜的生物量最多可增加25.77%;硝酸盐含量最多可减少29.74%;硝酸还原酶活性最多可提高28.27%.The antagonistic effect of micronutrient fertilizer on the nitrate accumulation in spinach was studied. The results showed that using urea with micronutrient fertilizer could made the biomass of spinach increased by a maximum of 25. 77 %,nitrate content in spinach decreased by a maximum of 29. 74 % and the nitrate reductase activity increased by a maximum of 28. 27 %, compared with using urea only.
