DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a bark mulching material for use in a greening business or agriculture.

[0002]

2. Description of the Related Art A mulching material is usually laid between trees and crops in order to suppress evaporation of water from the ground surface and to suppress weeds from growing. It is preferable that the mulching material does not easily scatter or run off, but a bark mulching material has attracted attention as a material suitable for this. Japanese Patent Application Laid-Open No. 2-186922 proposes a method for producing this bark mulching material, which comprises crushing bark finely and adding an asphalt emulsion and a sizing material to it to impart coloring and caking properties. Things.

[0003]

However, since the mulching material of the preceding example contains a mixture of fibrous materials, massive materials, and powder materials, the gap is small as a whole. Easy to clog. In addition, since bark that has been laid for a long period of time is used, it is decomposed and turned into fertilizer (so-called bark compost), and weeds sometimes grow after laying. Furthermore, since the asphalt emulsion is mixed, the dark brown color is too strong to impair the natural feeling and there is a concern about the effect on health.

The present invention has been made to solve such problems. In short, the bark of various hardwoods including Abemaki is crushed and separated into fibrous bark pieces and massive bark pieces (Abemaki bark pieces). A mulching material having different properties is manufactured from each.

[0005]

SUMMARY OF THE INVENTION Under the above-mentioned problems, the present invention crushes the bark of various hardwoods including Abemaki and selects fibrous bark pieces and massive bark pieces (Abemaki bark pieces).
Each of them is characterized by mixing vegetation paste which exerts a caking force when moisture is released.

Further, the present invention is characterized by adding the remaining powdery bark pieces selected to the above-mentioned massive bark pieces (Abemaki bark pieces).

[0007]

A fibrous bark fragment and a clumped component (Abemaki bark fragment) are selected from among various kinds of pulverized broad-leaved trees including Abemaki. Next, a vegetative paste which exerts a cohesive force when moisture is released is mixed into each. After laying the vegetation glue,
When moisture evaporates from the mulching material, it exerts a caking force, consolidates the whole into a plate shape and prevents scattering and runoff. In addition, bark pieces are not made into fertilizers, and weed vegetation is suppressed because the process from material extraction to commercialization is performed in a short time.

[0008]

FIG. 1 is a block diagram showing a method for producing a bark mulching material according to the present invention. First, bark of various hardwoods including Abemaki is pulverized by a chopper type pulverizer. In addition, hardwood other than Abemaki includes oak, beech, oak, etc., and it is preferable to use domestically produced trees which are free from salt damage and the like.

Next, this is sorted by a sorter. The sorting machine uses a sieve type, and is passed through sieves having different eyes in order, so that a massive bark piece (Abemaki bark piece), a powdery bark piece, and a fibrous bark piece are sorted in this order. It should be noted that a lump of bark (a bark bark piece) cannot be collected from a bark layer other than a thick bark layer.

[0010] The selected fibrous bark pieces are selected and put in a fixed amount in a stock yard, and vegetative paste is uniformly mixed with the foil loader or the like. Vegetable glue that exerts caking force when moisture escapes is suitable. Specifically, Sekisui Chemical Co., Ltd. manufactured by diluting S-Fix (trade name) by 50 times, and using this at an appropriate ratio Mixed into fibrous bark pieces (A type). The reason for using vegetation paste having such properties is that if the vegetation paste exerts a caking force before the application, the whole will be consolidated and difficult to handle.

On the other hand, the same operation is performed on the massive bark pieces (B type). By the way, there are powdery bark fragments in addition to fibrous bark fragments and lump bark fragments (Abemaki bark fragments), and these powdery bark fragments must be added to lumpy bark fragments (Abemaki bark fragments). There is also. Plays the effect of increasing the product,
This is to make effective use of the materials. Products containing vegetation paste are sealed in bags of both A type and B type.

The laying method of the mulching material is as follows.
First, the laying place is leveled, and then the mulching materials are laid out in a thickness of 3 to 5 cm and lightly compacted with a scoop or the like. After several hours, water evaporates from the vegetation glue, and its caking force is exerted to solidify the whole, preventing scattering and runoff.
In this case, the type A is fibrous, has many gaps, and has the advantage that clogging does not occur, and the type B is made of cork that is hard to rot, has excellent heat insulating effect, and has a good appearance. It has the advantage of being beautiful.

[0013]

As described above, since the present invention is as described above, two types of mulching materials having different properties can be manufactured from one raw material, and it is possible to cope with a wide range of uses and to effectively use the raw materials. be able to.
