Abstract

PROBLEM TO BE SOLVED: To solve the problem that there are occurring damages to trees in slope face greening works particularly at relatively remote and secluded places in the mountains; hoofed animals such as wild deer are tearing multimats laid on the surface of plant growth base layers with their hooves or eating new buds and young sprouts of the trees planted at the works during their curing period after seeding. SOLUTION: A method of preventing wild animals from eating sprouts of trees in slope greening works characterized in that a multimat (3) made of a chemical fiber-made russel net (5) placed on a multimate material (4) is laid on the plant growth base layer (2) constructed on a slope surface (1), and further a metal net (6) is laid on the multimat surface.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing edible animals such as wild deer from ungulate animals by sowing seeds of herbaceous plants for slope revegetation. It is about. 2. Description of the Related Art In general, in a slope revegetation work, seeds mixed in a growth base layer are multi-mats developed by the applicant of the present invention in order to protect the seeds from heavy rain, strong wind, frost heave or drought damage. Is applied to the surface of the vegetation base layer to cover it, and a curing period in which roots take root and germinate has passed. [0003] However, on a slope in a relatively remote mountainous area, a multi-mat covered with ungulates such as wild deer on the surface of the growth base layer during the curing period. The sprout that has just germinated by scraping the toe with the nail at the tip of the toe, or the sprouts that have germinated, and that have grown to about 10 cm, have been damaged. [0004] The present invention is provided to solve the conventional problems, and in the method for preventing germination damage from wild animals by slope revegetation, the present invention is applied to a slope. On the surface of the plant growth base layer, a mat is formed by overlaying a Russell net made of chemical fiber on a multi-mat material, and a wire mesh is further stretched on the surface of the multi-mat. DETAILED DESCRIPTION OF THE INVENTION A multi-mat is stretched on the surface of a plant growth base layer constructed on a slope, and a wire mesh is further stretched on the surface of the multi-mat. Together on the slope. by this,
Ungulates, such as wild deer, do not dislike this wire mesh and do not approach. In the drawings, reference numeral 1 denotes a slope, and 2 denotes a plant growth base layer constructed on the slope. The base is formed by adding konjac flying powder fertilizer (registered trademark: PM), coating fertilizer and seeds. Using a mortar spraying machine, water is mixed at the time of spraying the nozzle, and spraying is performed so as to have a predetermined thickness on the slope surface. Reference numeral 3 denotes a multi-mat covering the surface of the growth base layer, which is composed of a mat member 4 obtained by processing a relatively thin mat member 4 into a nonwoven fabric and a Russell net 5. Mat member 4 of the in-fine polyester staple fibers 1 m ² per 35gm weight per unit area, similar to capillary roots of plants, are to nonwoven fabric in random orientation. Its size is about 1.0 m wide and about 50.0 m long. Further, the mesh of the Russell net 5 is a lattice, a combination of a V-shape, a deformed square and a deformed hexagon, or an arbitrary shape such as a tortoiseshell, but the mesh is made of relatively large and lightweight polyethylene fibers, So that it is placed on top of it. The size of the Russell net is the same as that of the mat material. And the above-mentioned multi mat 3
It has a function of covering and enclosing the roots to protect the roots of the tree and a filter function. Reference numeral 6 denotes a wire mesh stretched on the surface of the multi mat 3. The wire mesh may be an arbitrary mesh such as a turtle shell or a lattice, and the size of the mesh is about 2 cm. Reference numeral 7 denotes an anchor pin for driving the multi-mat 3 and the wire net 6 into the ground and fixing the same, and reference numeral 8 denotes a herbaceous seed mixed in the growth base layer 2. [0009] [Examples of specific construction] Examples of construction of the present invention are as follows. First, a growth base material containing seeds is sprayed on the slope 1 using a mortar spraying machine to a predetermined thickness to form a plant growth base layer 2, and after the growth base layer is solidified, winding to be stretched toward the multi-mat 3 are from Hokata 1 ₁ of the law face 1 to expand the law to 1 ₂ roll. After the multi-mat 3 is stretched, the rolled wire mesh 4 is unfolded and stretched on the surface of the multi-mat 3,
The wire mesh 6 and the multi-mat 3 are integrally fixed to the slope 1 by driving an anchor pin 7 into a predetermined place. The present invention has the following effects since it has the above configuration. That is, since a wire mesh was further stretched on the surface of the multi-mat stretched over the surface of the growth base layer, at the stage of sprouting when the seeds in the growth base layer germinated, ungulates such as wild deer, this wire mesh, When stepping on the stretched slope, there is a habit of dislike this because the nail at the end of the toe is caught on the wire mesh, and it turned out that it does not approach the place where the wire mesh is stretched, so even after germination It has the effect of helping not to protect the shoots. Further, since the multi-mat is not damaged, it is possible to reliably prevent the plant base layer and the seeds from being washed away due to heavy rain and the like, and to promote the germination and growth of the seeds.
