Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a vegetation zone used for greening slopes, etc.

(Prior Art) Conventionally, various forms of the above-mentioned vegetation zone have been put to practical use, but one of the representative ones is a two-layered one as disclosed in Publication of Utility Model Publication No. 51-37283. There is one in which seeds, fertilizers, etc. are stored compartmentally between water-degradable sheets, and a net is placed above them.

By attaching the net, this vegetation belt will not be damaged during transportation or handling, and it can be securely fixed to the slope using skewers. This makes it easy to construct.

(The problem that the invention aims to solve) However, if too much fertilizer is applied, there is a risk that the seeds or germinated plants will suffer from concentration problems.
It is necessary to keep the amount of stored fertilizer small and add additional fertilizer after growth.

In addition, it is preferable to spray soil improvement materials on slopes with vegetation because they are often infertile (soil with poor physical properties, i.e., soil containing a lot of sand, clay, sand, etc.), but it is the most suitable soil improvement agent. Spreading desirable botanicals, such as peat moss and bark, onto slopes has the problem of being very tedious.

By the way, organic soil conditioners such as peat moss and bark can store a large amount of fertilizer and have an excellent function of alleviating concentration problems caused by fertilizers, but if left as is to dry, the fibers will wilt. The water absorbency is lost and the above-mentioned effects are not achieved.

However, the inventors of the present invention have discovered that if fibers such as peat moss are beaten and fibrillated, the surface area becomes large, the fibers have sufficient water absorption even when dried, and the original function can be reproduced.

(Means to solve the problem) The present invention was made based on the above knowledge,
The lower sheet of the conventional vegetation zone is made into a paper-like thin layer sheet in which pulp is made into a vegetable organic soil improvement material such as peat moss or bark that has been beaten and fibrillated into fine fibers. It is.

(Function) According to the above configuration, the peat moss and bark organic soil improving materials of the present invention are beaten and fibrillated, so that water absorption is maintained even after drying.

Therefore, when applied on a slope, the organic soil conditioner absorbs moisture from rainfall and retains water, and also absorbs fertilizers, especially nitrogen, to prevent concentration problems in plants, as well as It functions as a soil improvement material.

(Example) Next, the present invention will be explained as an example in Figs. 1 and 2.
This will be explained according to the diagram.

1 is the bottom water decomposable sheet, pulp 2 has 30 to 60
% of peat moss or bark beaten vegetable organic soil conditioner 3 is made into paper using a water-decomposable sizing agent as an additive, and then dried.
4 is a known water-decomposable sheet, for example, one in which an appropriate amount of long fibers made of a thermoplastic resin is mixed into pulp. Further, 8 is a net made of synthetic resin strings arranged in a grid pattern.

The vegetation zone A according to the present invention includes seeds 5 or fertilizers 6, etc., interposed between the two water-degradable sheets 1 and 4 in a scattered state, and a net 8 placed on top of the seeds 5 or fertilizers 6, etc. The thermoplastic resin is heated to a heat set line 7 using a heat roller having a grid-like convex portion.
Seeds 5 and the like are compartmentalized and stored between the two water-decomposable sheets 1 and 4.

Note that this vegetation zone may be sectioned with glue or the like without heat setting.

The vegetation zone having the above-mentioned structure is laid on a slope, etc., similar to the conventional one.

(Effects) As is clear from the above explanation, according to the present invention, both of the two sheets are water-degradable, so as in the past, seeds can tear the sheets and germinate.
Root. In addition, the lower sheet contains either peat moss or bark, a plant-based organic soil improvement material, and is fibrillated.
It has sufficient water absorption and functions as a natural organic soil conditioner.

Therefore, a larger amount of fertilizer can be stored than conventional ones, and plants can be prevented from dying due to running out of fertilizer. Moreover, if a vegetation belt is constructed on the slope, the result will be the same as that of spreading a soil conditioner, so the curing effort can be saved, which has many effects.

Claims (1)

[Scope of utility model registration request] Seeds, fertilizers, etc. are stored compartmentally between two upper and lower water-degradable sheets, and in a vegetation zone with a net provided above, the lower sheet is beaten into pulp and fibrillated into fine fibers. A vegetation zone characterized in that it is a paper-like thin sheet into which a vegetable organic soil improvement material such as peat moss or bark is made.
