Facility cultivation method for green asparagus in hot and humid areas

The invention relates to the field of green asparagus planting, in particular to a facility cultivation method for green asparagus in a hot and humid area, which comprises the following steps: selecting a first-generation improved variety of hybrid plants suitable for a local planting environment, drying the seeds in the sun for 2 days, and sequentially performing seed soaking, germination accelerating treatment, seedling raising treatment, transplanting treatment, field planting treatment and field management. The seed soaking agent is prepared from 2% indoleacetic acid wettable powder, amino-oligosaccharin, magnolol, forsythin and deionized water. During transplanting, a thin film prepared from a decomposed organic fertilizer, a ternary compound fertilizer, sodium n-butyl phosphoaminolevulinate, alternaria tenuissima protein and a nano aqueous adhesive is laid at the bottom in each planting groove, holes are punched in the thin films, one asparagus seedling is planted in each planting groove, and during tra
