Apparatus for producing seed paper for hydroponic cultivation and method for producing seed paper for hydroponic cultivation

摘要

The present invention provides, at low cost, seed paper for greatly reducing the cost of sowing in the production of immature vegetables and the like by hydroponics. A long sheet of thin leaf paper made of hydrolyzable paper, such as toilet paper, is supplied from the paper supply unit A, and a water-soluble adhesive is adhered to one surface thereof at a predetermined interval in the adhesive application unit C. A large number of seeds 13 are mounted on one surface of the long mount 11, and the seeds that have not adhered to the adhesive are removed from the long mount by raising the long mount 11. Thereafter, in the paper conveying/seed crimping section E, the long paper 11 is sandwiched by a pair of rollers 51 and 52 softer than the seeds 13 and press-contacted to produce the seed paper 15 . do. In this seed paper 15, a plurality of concave portions having a planar shape substantially the same as that of the target seed 13 and having a depth of 1/10 to 1 times the height of the target seed are provided on the long base 11, , the target seed is adhered to the inside of each recess with a water-soluble adhesive.
