Device for manufacturing seed paper for hydroponic cultivation and method for manufacturing seed paper for hydroponic cultivation

Abstract

The present invention provides inexpensive seed paper for greatly saving labor in sowing work in the production of immature vegetables and the like based on hydroponics. A vertically long liner of thin paper made of water-decomposable paper such as toilet paper is supplied from the liner supply part (A), and the water-soluble adhesive is attached to the vertical liner at predetermined intervals by the adhesive application part (C). One side of the long liner. By placing a plurality of seeds (13) on one side of the elongated backing paper (11) and lifting the elongated backing paper (11), seeds not adhered to the adhesive are removed from the elongated backing paper. Afterwards, in the backing paper conveying and seed crimping section (E), a pair of rollers (51, 52) softer than the seeds (13) are used to sandwich and crimp the vertically long backing paper (11) to produce the seed paper (15) . For the seed paper (15), a plurality of concave portions are provided on the vertically long backing paper (11), and the concave portion has a plan view shape approximately equal to the target seed (13), and has 1 / 10 times the height of the target seed ~ 1 times the depth, the target seed is bonded inside each concave portion with a water-soluble adhesive.

Description

technical field [0001] The present invention relates to a seed paper used in order to greatly save labor in hydroponic cultivation using a blanket medium, or in hydroponic cultivation in which many seeds need to be sown uniformly, young leaves, and the like. Background technique [0002] In recent years, immature vegetables such as young leaves, which have been rapidly spread, have small plant bodies, and therefore waste a lot at a normal sowing pitch, and yield per unit area is low. Therefore, in order to improve cultivation efficiency and increase yield, it is necessary to sow seeds at a narrower pitch than general vegetables. If seeds are sown at a pitch of 15 mm, for example, 4,400 seeds are sown per square meter, but if the seeds are sown manually, a large labor cost is required. Therefore, labor-saving technologies are particularly required in such fields. [0003] In order to solve this problem, a tape called a seeding tape or a seeding apparatus or the like is used...

AI Technical Summary

Problems solved by technology

However, in either method, an adhesive is applied to a relatively strong paper substrate, and the seeds are fixed using the adhesive, and a protective layer made of PVA or paper is provided on the surface to prevent the seeds from falling off, etc. It is the main object. In addition, either method needs several weeks or months as the cultivation of general vegetables during the cultivation period, and it cannot be said that it is the most suitable for sowing immature vegetables with a short growth period and seeds for seedlings. good
