  • Publication number: 20050262762
    Abstract: Method of sticking plant seeds on a seed fixing film mat and construction thereof in which a plant seed is formed into a multi-layered structure by enclosing the plant seed with a first and a second gel enclosures intercalated a layer of additive between the two gel enclosures. Afterwards, the one or several enclosed plant seed constructed as such is placed on a seed fixing film mat with an equal spacing and stuck to the seed fixing film mat by heating and fusing the gel enclosures. The plant is nourished directly by the additive so as to eliminate regular fertilizing work thereby the cultivation procedures can be simplified and production cost curtailed.
