Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a seed spraying net that facilitates the germination and growth of woody plants or flowers during spraying work such as seed spraying work in civil engineering work. It is.

(Conventional technology) In recent years, in natural restoration work on slopes used for land development, Western grass seeds have been used in seed spraying to stabilize slopes through early greening, and native grasses such as Japanese turfgrass and mugwort have been used. ,
We are working to restore nature by actively planting secondary vegetation by sowing seeds of Japanese grass, etc., with Western grass seeds.

However, the germination conditions for herbaceous seeds are more difficult than for Western grass seeds, so when mixed sowing, herbaceous plants lose ground to Western grass, and stable germination and growth cannot be expected. In addition, the current situation is that with woody plants, which have even more difficult germination and growth conditions than herbaceous plants, no germination can be expected even when mixed with Western grass seeds. The only option is to use seedlings, and if you plant them, you will have to pay for the seedlings, so it will be expensive, and if you spray the seeds after planting, it will cause the trees to die. Since planting trees would expose the slope, there was no simple and stable slope protection method that used seed spraying to combine woody plants and western grass.

In addition, in recent years there has been an increasing demand for flowers to bloom not only on the shoulders of the slopes but also on the slopes of tourist roads, but the seeds of the flowers are similar to the seeds of woody plants and are mixed with Western grass seeds. Since it is extremely difficult to germinate and grow in such cases, the only way at present is to grow flowers on the shoulders of slopes, where there is no need to grow western grass, which is not related to slope protection.

(Problems to be solved by the invention) The present invention has been made in view of the above-mentioned circumstances.
The problem to be solved is to provide a spraying net that can stably germinate and grow both woody seeds and flower seeds even when seed spraying work is performed on western grass as part of slope protection work.

(Means for Solving the Problems) In order to solve the above problems, the present invention has adopted a method in which seedbeds are attached to the net in dots or lines, and woody plants are grown in the seedbeds. In addition to the seeds and fertilizer of woody plants or flowers, the seedbed is filled with soil improvement materials and water retention materials, and furthermore, Western grass seeds do not mix into the seedbed when spraying seeds. To provide a net for seed spraying with a seedbed, in which a cover sheet of the above is attached to the surface of the seedbed.

(Function) After deploying the seed spraying net with a seedbed of the present invention on the slope 7 and fixing it to the slope 7 with the anchor 6, the seed spraying 9 is performed, and then the removal net 8 is removed from the seed spraying net with the seedbed. Then, the seedbed cover sheet 3 is automatically removed together with the removal net 8.

(Example) The present invention will be described below with reference to Examples. As shown in Fig. 1, the seed spraying net with a nursery bed of the present invention is made of polyethylene to a degree that does not hinder the germination and growth of plants. A seedbed 2 is attached to a net 1 at a distance of . The seedbed 2 may be attached to the net 1 by using an adhesive, but in this embodiment, a notch 10 is cut into the seedbed 2 as shown in FIG. After fitting the net 1, wrap the seedbed holding tape 11 around the seedbed 2 as shown in FIG.
They are each fitted in such a way that they cannot be removed.

Furthermore, as shown in FIG. 2, the seedbed 2 has a bottom paper 12 affixed to the bottom surface of the seedbed 2, which easily adapts to the slope surface 7, and contains vermiculite, perlite, or peat moss as a soil conditioner or water retention material 5. , zeolite, etc., slow-release fertilizer 14, and seeds 4 of woody plants or flowers are filled, and the upper surface of the nursery bed 2 is filled with germination of seeds,
A top paper 13 that does not hinder growth is pasted to form a seedbed 2 containing seeds 4 of woody plants or flowers, slow-release fertilizer 14, and soil improvement material or water retention material 5. Seedbed 2 is made of hardened peat moss plant fibers, cardboard, or other material that allows the roots of woody plants and plants to penetrate through the seedbed, and that does not decompose over the long term and impede the growth of woody plants. The seedbed 2 may have any shape as long as it has a circular area with a diameter of about 10 cm.
In addition, the depth of seedbed 2 is 0.5cm to 20cm depending on the spraying thickness.
cm is considered good.

Furthermore, as shown in Figure 2, a water-insoluble film such as polyethylene is pasted as a cover sheet on the top surface of the seedbed to prevent western grass from getting mixed in during seed spraying. As shown in the figure, in order to remove the seeds after spraying, the seedbed 2 and the cover sheet 3 are strongly attached to the removal net 8 as shown in FIG. Any method may be used as long as it is stronger than adhesion.

(Effects) As described above, according to the seed spraying net with a nursery bed of the present invention, the seeds of woody plants and seeds of flowers, which could not be expected to germinate and grow when mixed with Western grass, can be mixed with Western grass. It is possible to stably germinate and grow the seeds of woody plants or flowers while satisfying the early protection of slopes by using this method. Since it allows the plant to grow, it has a remarkable effect. It is also a truly groundbreaking invention because it has made it possible to perform spraying work on tourist roads that allows flowers to bloom while protecting the slopes, something that had not been possible until now.

In addition, compared to conventional netting seed sprayers, the on-site work is extremely simple, just removing the removal net from the nursery, making it possible to remove the seeds of woody plants or flowers from overseas, which was previously considered impossible. This is a truly wonderful invention because it can be grown on slopes even when mixed with grass seeds.
