[Title of the Invention]
Hydrophilic agent for potted plants and retaining tool
[Claims]
1. Water retention agent of high-molecular weight for potted plants.
2. A retainer device composed of bag to hold the water-retention agent, which permits water
and plant root penetration, with pores small enough to prevent water to runoff that, in turn
fits onto the aeration plate fitted into the bottom of the planter pot.
[Excerpt from Detail Description of the Invention and Drawing]
This invention involves mixing polyacrylamide and other high-molecular hydrophilic
materials into the potted soil, thereby encouraging root growth while reducing the frequency of
watering.
The retaining tool consisting of the bag (1) and the aeration plate (10), by soaking them
with the hydrophilic agent so that they have completely absorbed the hydrophilic agent before
placing in the planter pot prior to placing the soil, it can be kept free of the agent, the process
can be very simple, clean and quick. The root can penetrate the bag, but it must prevent the
water from passing through it. The grain size of the high-molecular weight hydrophilic agent
must be 1.5 to 3mm.
[Explanation]
The fixture for the hydrophilic agent for potted plant of the related invention (Claim 2), that
is to put the hydrophilic agent for potted plant in the bottom in the potted soil, invented to
maintain and extract the function of the hydrophilic agent for potted plant of the specified
invention (Claim 1). They, therefore, constitute the product and a product for handling the
product.
