Broad bean film-covering trench-sowing cultivation method used in high-elevation chilling dark and humid region

The invention discloses a broad bean film-covering trench-sowing cultivation method used in a high-elevation chilling dark and humid region and belongs to the field of crop planting. The method comprises the following steps: (1) land selection and preparation; (2) ridging and film covering; (3) seed treatment; (4) sowing and fertilizing; (5) field management; and (6) harvesting in good time. Afterplanting by adopting the cultivation method, the emergence rate of broad beans can be up to 98.1% or above, seedlings are tidy, the yield per mu of the broad beans can reach 318 kg or more, and meanwhile, diseases and insect pests are effectively controlled; the incidence rate of red spot disease is lower than 7.2%, the incidence rate of rust disease is lower than 5.4%, the incidence rate of fusarium wilt disease is lower than 11.6%, the aphid pest rate is lower than 3.1%, and the broad bean weevil pest rate is lower than 8.7%. 本发明公开了高寒阴湿区蚕豆膜测沟播栽培方法，属于农作物种植领域。该方法包括以下步骤：(1)选地整地；(2)起垄覆膜；(3)种子处理；(4)播种施肥；(5)田间管理；(6)适时采收。
