(First embodiment)
With reference to FIG. 1 thru | or FIG. 4, the planting mat 30 which concerns on 1st embodiment of this invention is demonstrated.
The planting mat 30 is a planting mat 30 used as a mulching material that covers the ground surface on which trees T such as street trees are planted, and includes a chip 31 and a bag body 32.

  The chip 31 is made of an organic material. Specifically, it is wood waste made by pulverizing a piece of wood that has been produced as a waste material from a wood manufacturer or the like.

The bag body 32 is a bag that encloses the chip 31 therein, and is formed by stitching organic fiber material, here, non-woven fabric. Therefore, the bag body 32 has water permeability.
As shown in FIG. 1, the outer shape is a substantially square shape, and is formed with one deep slit 33 extending from the end portion 32 a (here, the center of one side of the square) to the location beyond the center portion 32 c of the bag body 32. Part 34. That is, the bag body 32 has a bifurcated bag shape.
Further, fertilizer (not shown) is enclosed in the bag body 32 together with the chip 31.
The chip 31 and the fertilizer (not shown) are sealed in the bag body 32 by opening the other end 32b on the opposite side of the end portion 32a where the slit 33 is formed. The other end 32b is sewn with a thread.

As shown in FIGS. 3 and 4, the planting mat 30 configured as described above is configured such that the root of the tree T is sandwiched between the slits 33 of the planting mat 30 so as to cover the ground surface on which the tree T is planted. Attached to T. At this time, in order to make it difficult for the planting mat 30 to come off the root of the tree T, the splitting portions 34 are overlapped with each other so that the splitting portion 34 wraps around the entire root of the tree T.
In addition, by overlapping the dividing portions 34 with each other in this manner, there is an advantage that rainwater can easily gather at the central portion 32c of the planting mat 30 and the tree T can be promoted.

  Here, as shown in FIG. 5, when there are two strings 36 connected to the respective ends of the divided portions 34, the divided portions 34 can be kept connected to each other by connecting them together. By doing so, the planting mat 30 is more difficult to come off the tree T.

According to such a planting mat 30, since the ground surface is covered, the propagation of weeds can be suppressed similarly to the conventional planting mats 10 and 20, and the soil runoff can be prevented.
Moreover, since the chip | tip 31 which is a wood chip | tip, and the bag body 32 which consists of a nonwoven fabric which is an organic fiber material decay in several years after construction, it does not generate | occur | produce dust and is environmentally friendly. Moreover, the decayed planting mat 30 itself becomes an organic fertilizer. Moreover, since the chip 31 is made by recycling waste materials, this point is also environmentally friendly.

Further, since the bag body 32 has a bifurcated bag shape having a split portion 34 in which a slit 33 is formed from the end portion 32a to the center portion 32c, the root of the tree T can be sandwiched deeply by the split portion 34. The planting mat 30 is difficult to come off due to strong winds.
Furthermore, since the chip 31 is enclosed in the bag body 32 and the planting mat 30 has a certain amount of weight, it is difficult to be blown away by strong winds.

Further, since the planting mat 30 in which the chips 31 are enclosed in the bag 32 is transported to the construction site and the planting mat 30 only needs to be arranged at the site, the construction is extremely easy.
And since the fertilizer is also enclosed with the bag body 32, the fertilizer in the planting mat 30 oozes every time it rains, and the growth promotion of the tree T can be aimed at.

(Second embodiment)
Next, a planting mat 30 according to a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol was attached | subjected to the same part as 1st embodiment.

  The planting mat 30 according to the present embodiment has a circular outer shape, and a through hole 35 is formed in the central portion 32 c of the bag body 32. And the slit 33 is extended from the edge part 32a of the bag body 32 to the through-hole 35, and the bag body 32 is a forked bag shape. That is, the tree planting mat 30 has a donut shape with slits 33 formed therein.

Since the bag body 32 is formed in a bifurcated bag shape having a through-hole 35 formed in the central portion 32c and a divided portion 34 in which a slit 33 extending from the end portion 32a to the through-hole 35 is formed, The planting mat 30 can be attached to the tree T so that the peripheral surface is along the root of the tree T. Therefore, even when the tree T is thicker than the diameter of the through hole 35, the slit 33 is opened only to a minimum, and therefore the planting mat 30 is more difficult to come off. Of course, when the tree T is thinner than the diameter of the through-hole 35, the slit 33 does not expand beyond the originally formed width at the time of mounting, so that the planting mat 30 is difficult to come off.
Here, it is the same as that of 1st embodiment that environmental property and workability are good.

  In the first and second embodiments, the bag body 32 has a bifurcated bag shape. However, the bag body 32 is not limited to this, and may have a shape such as a substantially rectangular pillow as shown in FIG. Even if it is such a shape, construction does not require time and effort, and the tree-planting mat 30 will eventually decay and return to the soil.

Moreover, although the chip 31 made of an organic substance is assumed to be wood waste, the present invention is not limited thereto, and may be, for example, a cocoon, a fallen leaf, or a mixture thereof.
Further, although the bag body 32 is a non-woven fabric, it may be a normal woven fabric. Furthermore, if it has water permeability and decays in the future, it is not limited to these.

Moreover, although the fertilizer was enclosed with the chip | tip 31 in the bag body 32, only the chip | tip 31 may be enclosed.
Moreover, although the connector 36 is a string, it is not limited to this.

  In the first embodiment, the slit 33 is formed to extend from the bag body 32 end 32a to the central portion 32c. However, the present invention is not limited to this, and the slit 33 is more than that according to the first embodiment. It may be formed shallow.

  In the second embodiment, the tree mat 30 has a circular outer shape and the through hole 35 is formed in the central portion 32c of the bag 32. However, the tree mat 30 may have any shape, Furthermore, the through hole 35 may not be formed.
