摘　　要：研究了不同肥料搭配对京水菜生长、产量及品质的影响.结果表明,高氮、中高钾肥量对京水菜株高、叶数、开展度、叶面积、产量和品质有明显的促进作用;随着氮肥量的增加,株高、叶面积增加,随着钾肥量的增加,品质不断提高;产量与叶数、开展度和叶面积之间存在明显的相关.Effects of different fertilizer combinations on the growth, yield and quality of Brassica juncea var. multisecta L. H. Bailey were studied. High N rates and medium and high K rates markedly promoted plant height, leaf number, leaf expanding degree, leaf area, yield and quality of the plants. Plant height and leaf area increased with N rates and quality improved with increasing K rates. A significant correlation was observed between yield and leaf number, leaf expanding degree and leaf area.
