Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention provides a plant growth base material and a method for constructing the same.

[0002]

2. Description of the Related Art Conventionally, in order to create a plant growth base on a slope, a synthetic resin net or a diamond-shaped wire mesh is fixed to the slope with a pin or the like, and a plant growth base material made of earth and sand, bark compost, peat moss, and the like. Or continuous continuous fibers wound on a bobbin are conveyed by hydraulic or compressed air and sprayed together with the base material.

The work of stretching a net or a wire net on a slope is complicated, and the work on the slope requires a long process without danger. In addition, in order to mix continuous long fibers into the growth base, dedicated bobbins, bobbin cases, and materials such as a yarn feeding device are required, and the management of the materials is complicated,
Space for that is also needed.

[0004]

According to the present invention, it is possible to avoid the work of stretching nets and wire nets performed on a slope,
An object of the present invention is to provide a method for constructing a stable plant growth base on a slope without relying on complicated continuous filaments.

[0005]

According to the present invention, 10% to 50% of coir fiber having a length of about 5 cm to 20 cm is added to a plant growth base material such as earth and sand, bark compost, peat moss, and coco peat.
By mixing with a volume of, the fixing effect of the growth base material with the coir fiber and the bonding agent is intended to easily create a more stable growth base.

Earth and sand used as a plant growth base material,
Materials such as bark compost, peat moss, and coco peat are mostly powders or granules, and these powders and granules are fixed by a bonding agent such as asphalt emulsion, cement, acrylic resin, or vinyl acetate resin. However, if it adheres too strongly, it becomes too hard and causes germination failure of the plant, so its use is limited. Therefore, nets, wire mesh, and continuous nets are used as supplementary materials to supplement the adhesive force, prevent runoff and erosion of the growth base material due to rainwater runoff or infiltration, and maintain stability until the plant root system is fully developed. Long fibers and the like are used.

[0007] In the present invention, instead of this, a coir fiber having a length of about 5 cm to 20 cm is mixed into a plant growth base material consisting of powder and granules, and the long fiber is mixed with a bonding agent and a plant growth base material. It exerts a fixation effect by the sticking force and creates a stable growth base against erosion caused by rainwater or seepage water. The length of the core fiber, the mixing ratio of the long and short fibers, the volume ratio of the core fiber, and the like are appropriately selected depending on the type of the growth base material, the slope of the slope, and the type of the bonding agent. It is also possible to adopt a method in which these coir fibers are mixed with the growth base material and sprayed, or separately conveyed and sprayed together. As another method, the same effect as when a net is stretched can be obtained by spraying a slope with coco fiber and a bonding agent to form a mat-like body and spraying a growth base material on the upper surface thereof. . Conversely, by forming a mat-like body of coir fiber on the upper surface of the growth base material, erosion due to rainwater is prevented, a mulching effect is exerted, and uniform germination and a stable plant growth base are obtained.

The feature of the present invention is that reinforcement is provided by nets or wire meshes, unidirectional or bidirectional, whereas a large number of coir fibers are randomly entangled in multiple directions. The confounded tissue is established,
It has the effect of preventing cracks, cracks, and the like that occur with the drying of the growth base material, and can maintain the stability of the growth base material until the root system of the plant is sufficiently developed as a pseudo root system. It is well known that fiber itself is a water-absorbing material, and its properties enhance the water retention capacity of the growth base material, promote germination and rooting of plants, and prevent germination from drought damage. Protect plants during the season.

[0009] The coir fiber itself is organic,
Unlike synthetic resin nets and wire nets, they return to soil with decay and are environmentally friendly. In addition, compared to straw and the like, the rate of decay is slower, and it has a strength as a reinforcing fiber material, and sufficiently exerts its function as a pseudo root system until the root system of the plant is fully developed.

[0010]

According to the plant growth base material and the method of forming the same according to the present invention, it is not necessary to stretch nets or wire netting on the slope, the process is shortened, the economic effect is large, and the risk on the slope is reduced. Work is also reduced. or,
A stable plant growth base can be easily and safely constructed with a general spraying machine without using equipment such as continuous fibers.
