Problems solved by technology

On the other hand, if the polyurethane prepolymer is too small on the contrary, there is a problem that the shape retention necessary for the plant cultivation substrate cannot be maintained, and the filling material falls and crumbles when held by hand. There is also room for improvement

Embodiment Construction

[0046] Embodiments of the substrate for plant cultivation according to the present invention and the method for manufacturing the substrate for plant cultivation will be described with reference to the drawings and experimental results.

[0047] The plant cultivation substrate can be used for a planting device such as while making a planting container float on the water, and the floating planting device, such as figure 1 with figure 2 As shown, a planting container 2 for accommodating a plant cultivation base 1, a water storage container 3 for storing planting water W, and a planting tool 4 for maintaining the floating posture of the planting container 2 are provided, thereby cultivating plants planted in the plant cultivation base 1. Plant P.

[0048] The planting container 2 floats near the water surface of the stored water W, is formed into a bottomed cylindrical shape by hollow resin having a small specific gravity such as water, and has a water immersion hole 2a penetra...

Abstract

Provided is a plant cultivating substrate which satisfies e.g. the water absorptivity required for plant cultivation, shape retentivity and flexibility and a method of manufacture thereof. In the plant cultivating substrate and the method of its manufacture, at least water-retentive filling material, water, urethane prepolymer and polyol are reacted with each other.

Description

technical field [0001] The present invention relates to an artificial plant cultivation substrate which can be used as a substitute for ordinary soil to cultivate plants by enclosing their roots and its manufacturing method. Background technique [0002] As a method for producing such a plant cultivation substrate, in the prior art, various methods are known in which a small amount of polyurethane prepolymer is dispersed in water or a solvent for bark composting, rice husk composting, etc. A method of producing a water-retaining filler by mixing and reacting it to solidify, a method of producing a suspension containing a water-retaining filler, water, and a polyurethane prepolymer by reacting and curing it (for example, refer to Patent Documents 1 and 2). [0003] Furthermore, there is also known a method of mixing a water-retentive filler and a polyurethane prepolymer in advance, adding a small amount of water to the mixture, and reacting and curing the mixture (for example...
