莴笋+鲜食玉米轮作模式下高效设施栽培模式探讨

Exploration of the Efficient Facility Cultivation Model of Lettuce + Fresh Corn Rotation

天津市为了有效利用当地独特的地理气候资源,丰富蔬菜供给,提高土地利用率及种植效益,在多年生产实践基础上总结了“莴笋-鲜食玉米-鲜食玉米”和“莴笋—鲜食玉米—莴笋”两种一年多茬的轮作栽培模式,包括作物茬口安排、田间种植管理技术要点、病虫害防治、适时采收等,利用冷棚设施栽培,大大提高土地复种指数,减少病虫害发生,提高种植经济收益。通过2年的试验示范,收到了良好效果,可为京津冀地区发展设施农业种植区提供有益参考。

In order to effectively utilize the unique geographical and climatic resources of the local area to enrich vegetable supply,improve land use efficiency,and planting efficiency,based on years of production practice,two rotation cultivation models for more than one year,namely “lettuce-fresh corn-fresh corn” and “lettuce-fresh corn-lettuce”,have been summarized,including crop rotation arrangement,the main technical points of field planting management,disease and pest control,and timely harvesting,etc.The use of cold shed cultivation facilities can greatly improve the land multiple planting index,reduce the occurrence of diseases and pests,and increase the economic income of planting.Through 2 years of experimental demonstration,good results have been achieved,which can provide useful reference for the development of facility agriculture planting areas in the Beijing,Tianjin and Hebei region.
