为提高单位面积土地利用率、产量和效益，降低化肥农药对蔬菜和环境的影响，推进永登县高原夏菜产业高效健康发展，经过多年开展紫叶莴笋栽培技术试验研究，从品种选择、播期安排、整地施肥、田间管理、病虫害防治和采收等环节总结了紫叶莴笋一年两茬高效栽培技术，以期为当地紫叶莴笋生产提供参考。

In order to improve theutilization rate, yield and economic benefit of land per unit area, reduce the impact of fertilizers and pesticides on vegetables and the environment, and promote the efficient and healthy development of highland summer vegetable industry in Yongdeng County, a series of experimental studies on purple leaf lettuce cultivation techniques have been conducted over several years. This study summarized the efficient two-crop-per-year cultivation techniques for purple leaf lettuce production, covering aspects such as variety selection, sowing schedule, land preparation and fertilization, field management, pest and disease control, and harvesting, with the aim of providing a reference for local purple leaf lettuce production.
