Solar heat storage plant and weed prevention mat

Abstract

To provide a weed-preventing mat for preventing the growth of weeds on the ground and slopes of roads, railways, rivers, parks, etc., and their surrounding areas. [Solution] This weed control mat 10 is made from high-performance rubber molded into a 5mm thick sheet, and can be laid down without weeding even when weeds are already overgrown. This is because the weed prevention mechanism is not conventional suppression but death. The aim is to forcibly expose weeds to high heat for an extended period of time, destroying their cell membranes and causing them to die in a natural environment. By using special rubber with excellent durability and weather resistance, once laid down, it can be expected to last for decades.

Description

[Technical Field]

[0001] This invention relates to a weed control mat that has the function of preventing the growth of weeds on the ground and slopes of roads, railways, rivers, parks, etc., and their surrounding areas. [Background technology]

[0002] Several methods have been put into practical use as weed control methods. Herbicides are commonly used as a chemical weed control method, but they have problems such as their effectiveness being temporary, they can damage surrounding crops, and they can cause pollution if they run off into irrigation water.

[0003] Alternatively, a method of laying down a weed control sheet made of nonwoven fabric or the like is also widely used. This method can safely prevent the growth of weeds by blocking light from the area where it is laid, but it has some issues, such as poor durability (only 1-2 mm thick), poor weather resistance (prone to UV degradation), the time and cost required for installation, and the tendency to regrow from the edges and joints. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] See Special Publication No. 4-52727, etc. Summary of the Invention [Problem to be solved by the invention]

[0005] The purpose of this invention is to provide a weed control mat that does not affect the surrounding environment (soil and water) because it does not use chemicals, is durable enough to withstand being stepped on by people or vehicles for a long period of time, is resistant to deterioration due to ultraviolet rays, wind and rain, and is easy to transport and lay down. [Means for solving the problem]

[0006] The weed control mat of this invention is designed to kill weeds by utilizing heat storage from sunlight and high temperatures.

[0007] The weed control mat of this invention has high thermal conductivity due to a special manufacturing process, and is effective in killing weeds even in the shade.

[0008] The weed control mat of this invention is made from high-performance rubber (recycled domestic waste tires) molded to a thickness of 5 mm, and has high standards of durability, weather resistance, slip resistance, and light blocking properties.

[0009] When the outside temperature is above 20°C (April to October), the weed control mat of this invention applies high heat to the weeds underneath for a long period of time, causing them to wither and die. This is a clean method that does not use any chemicals or electrical energy. Moreover, because it acts directly on the weeds, there is no need to weed or remove roots when laying the mat.

[0010] The shape and weight of the weed control mat of this invention are designed so that it can be carried and laid down by one person, and the cost of installation is low.

[0011] When installing the weed control mat of this invention on a slope such as a slope, it can be easily fixed in place using commercially available stakes (pegs) or the like. [Effects of the Invention]

[0012] The weed control mat of this invention is environmentally friendly, serves its purpose reliably for a long period of time, and can be installed at low cost. When the installation area is large, it can be effectively used in combination with conventional weed control sheets to reduce the unit cost of materials. It can also be effectively used at the edges and joints of existing weed control sheets. [Brief explanation of the drawings]

[0013] [Figure 1] 1 is a perspective view of a weed control mat according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0014] The weed control mat 10 shown in FIG. 1 is used to prevent weeds from growing on the ground, slopes, and the like.

[0015] The weed-control mat 10 shown in Figure 2 is used to prevent weeds from growing around the roots of objects to be protected that stand above the ground, such as guardrail posts, fence posts, and road signs installed along the side of the road.

[0016] The weed control mat 10 shown in FIG. 2 can be easily formed with insertion holes 210 and dividing sections 220 using a blade such as a cutter knife to fit the circumference, diameter and shape of the object to be protected. [Example]

[0017] The weed control mat 10 shown in Figure 1 is laid on the ground and slopes over weeds that have grown on the ground. This has the same effect whether the weeds are thriving or dead.

[0018] The weed control mat 10 shown in FIG. 2 is laid down with one or more insertion holes 210 and dividing sections 220 made according to the shape of the object to be protected and the installation situation. [Industrial Applicability]

[0019] The weed control mat of this invention is a completely new, safe and reliable method that uses sunlight and the heat associated with it to promote the destruction of weed cell membranes (cell death) rather than the conventional methods of chemicals or shading. The dimensions and weight are also designed with ease of construction in mind, making it easy to handle and shortening the construction period. Furthermore, it has excellent durability and weather resistance, and its effectiveness can be maintained for a long period of time, so it is expected to be more cost-effective than conventional construction methods. In this way, it is friendly to both the environment and people, and is optimal because it promotes the death of weeds reliably, contributes to improved visibility, suppression of pest outbreaks, safe passage, and protection of the pavement.
