甘肃河西走廊灌区芦笋+娃娃菜间作高产高效栽培技术

芦笋是一种高档而名贵的蔬菜，定植后第3年才进入盛产期；种植前期产量低收益少。利用芦笋定植前期根系较小、行距较宽和娃娃菜株型小、根系浅的特性，在芦笋定植当年进行“芦笋+娃娃菜”间作生产，可提高土地利用率和早期收益。我们基于临泽县当地种植专业合作社的生产实践，从茬口安排、品种选择、育苗、整地覆膜、灌溉系统配备、定植(移栽)及田间管理等方面总结了河西走廊灌区芦笋+娃娃菜间作栽培技术，为河西灌区芦笋-娃娃菜间作栽培提供技术支持。

High Yield and Efficient Cultivation Techniques for Asparagus and Baby Cabbage Interplanting in Irrigation Areas of Hexi Corridor

Asparagus is one of the high-end vegetables, it only enters its peak production period in the third year after planting, resulting in low yield and low returns in the early stages of planting. By utilizing the characteristics of small root system in the early stage of asparagus planting, wide row spacing, small plant type of baby cabbage, and shallow root system in the early stage of baby cabbage planting, the intercropping production of ''asparagus + baby cabbage'' can be carried out in the year of asparagus planting, which can improve land use efficiency and early returns. The cultivation techniques of asparagus and baby cabbage interplanting in irrigation areas of Hexi Corridor are summarized from the aspects such as stubble arrangement, variety selection, seedling raising, soil preparation and film mulching, irrigation system allocation, planting (transplanting) and field management.
