摘　　要：5个播期、2种种植密度条件对京水菜生长及产量的影响研究结果表明:随着播期的延迟,京水菜出苗、定植、采收所需时间逐渐变短;同一种植密度下,随着播期的延迟,京水菜株高、叶数、开展度、产量均逐渐增加。同一播期,种植密度(株行距15 cm×20 cm)较大时,株高相对较高,叶数、开展度、产量相对较低;种植密度(株行距20 cm×25 cm)较小时,株高相对较低,叶数、开展度、产量相对较高。Effects of five different sowing data and two planting density on the growth and yield of Brassicajuncea var.multisecta L.H.Bailey were studied.The results showed that as the sowing time delay, the number of days needed to emergence, planting, harvest were gradually reduced.Under the same planting density, as the sowing time delay, plant height, leaf number, the development and production were gradually increasing.Under the same sowing date, planting density （15cm×20cm）was larger, the plant height was relatively higher, the leaf number, the development and production were relatively lower.Planting density （20 cm×25cm ）was lower, the plant height was relatively lower, the leaf number, the development and production were relatively larger.
