Green leaf vegetable plug seedling method

The invention belongs to the technical field of crop cultivation, and discloses a green leaf vegetable plug seedling method. The method particularly comprises steps: moisture preservation and temperature increase are achieved through a floating mulching film after sowing, the plug bottom is soaked in water for 40min/day before seedling emergence, the film is removed for continuous water soaking for 40min/day after 60% of seeds are revealed, and watering is then carried out when 60% of seedlings grow two true leaves. The method of the invention is technically characterized in that in the case of sowing and well watering, the floating mulching film is arranged at once, plug water soaking is carried out for 40min every day before seedling emergence, the film is removed when more than 60% are revealed, continuous plug water soaking for 40min every day is carried out, watering is then carried out when more than 60% grow two true leaves, and in the case of 4 to 6 leaves, transplantation is carried out. The method of the invention has the advantages that the operation is simple, the seedling emergence is tidy and quick, and the seedling body is strong in the later stage of seedling, and can be applied to green leaf vegetable plug seedling.
