Submerged plant underwater turf cultivation structure and submerged plant underwater turf planting method

The invention discloses a submerged plant underwater turf cultivation structure and a submerged plant underwater turf planting method. The submerged plant underwater turf cultivation structure comprises a lower clay layer laid in a hard seedling growing water pool with the flat bottom surface or a water tank, a seedling growing net frame made of degradable natural materials is laid above the lower clay layer, an upper clay layer is laid on the seedling growing net frame, the seedling growing net frame and the upper clay layer are bonded together to form a seedling growing base material, and the submerged plants are arranged on the seedling growing base material. The submerged plant underwater turf cultivation structure has the following advantages that the seedling growing base material is made of natural materials so as to be capable of degrading gradually after being planted underwater; the whole turf is flexible and cable be packed into a roll to be transported conveniently to greatly save transportation cost; due to large flexibility, the turf can be directly spread in planting and can be also cut into modules to plant in a scatter mode; and labor is saved, simultaneously operation in water in planting is reduced, and labor intensity is greatly reduced.
