摘　　要：田间试验研究不同用量的液体肥料(20-7-18)对菜心地上部产量和品质的影响,结果表明:当液体肥料每667m2用量为40L时菜心地上部产量最高,与等养分的进口复合肥(15-15-15)比较,地上部产量增加9.3%,菜心的Vc含量相对提高8.6%,磷吸收量提高11.3%,硝酸盐含量降低13.2%。The field experiments of different fluid fertilizers（20-7-18） applied on flowering Chinese cabbage were conducted to study the above-ground yield and quality. The results showed that the application of 40L per 667 m2 fluid fertilizers was the most effective in improving yield by 9.3% compared with solid fertilizer treatment. The content of Vc and phosphate absorption in 40L per 667m2 fluid fertilizers treatment was increased by 8.6% and 11.3%, and the nitrate content was decreased by 13.2%.
