The invention relates to the technical field of garlic planting, in particular to garlic
seedling emergence equipment for agricultural production and a
seedling emergence method.The garlic
seedling emergence equipment comprises a mulching film, a seedling guide cylinder
assembly and a
phase change heat preservation
assembly, a circular through hole is formed in the mulching film, the seedling guide cylinder
assembly comprises a plurality of vertically-arranged seedling guide cylinders, and the lower ends of the seedling guide cylinders penetrate through the circular through hole and are inserted into soil; the seedling guide cylinder comprises an inner cylinder and an outer cylinder, the outer cylinder sleeves the outer side of the inner cylinder, an annular interlayer cavity is formed between the outer cylinder and the inner cylinder, the annular interlayer cavity is filled with the
phase change heat preservation assembly, an annular
flange is arranged in the middle of the outer side of the outer cylinder, and the annular
flange is attached to the lower surface of the mulching film and is in sealed connection with the edge of the circular through hole in a
hot pressing welding mode; a covering film is arranged at the top opening inside the inner cylinder; a closed micro-
domain space is defined by the seedling guide cylinder, the mulching film and the covering film together,
air convection heat exchange is reduced, the
phase change heat preservation unit continuously adjusts the temperature fluctuation range in the cylinder, and
normal growth and development of seedlings in a low-temperature environment are guaranteed.
