１−３７２８２号公報等で提供されている。BACKGROUND OF THE INVENTION Straw prevents evaporation and freezing of soil moisture to provide a favorable environment for germination of seeds and growth of plants, and prevents runoff of seeds and sediment due to wind and rain. In addition, straw becomes a fertilizer and a soil conditioner after humus, and is a nutrient source necessary for plant growth. Therefore, in view of the effectiveness of such straw, a vegetation zone in which a seed layer in which seeds, fertilizers, and the like are sandwiched between a plurality of sheets is covered with a knitted straw is actually used.
It is provided in Japanese Patent Publication No. 1-37282.

Even if it is pressed with a rope or the like, it may be blown by strong winds and scattered if there is little snow during the winter, or it may be blown off together with young plants at the early stage of germination in spring. In addition, snow tends to adhere to the straw, and if there is snow, the snow may slip off along with the straw during the snowmelt season, and the straw may be thrown in to collapse the slope.

素が不足して窒素飢餓の状態を招来する。By the way, low molecular weight ammonia nitrogen is necessary for humification of organic substances, and this ammonia nitrogen is a nutrient necessary for plant growth. Further, when the ratio of carbon and nitrogen of the organic matter applied to the soil, that is, the C / N ratio is 20 to 30 or less, since the organic matter contains sufficient nitrogen, the organic matter is easily decomposed to cause humification. However, the C / N ratio of 20 to 30 or more, which has a low nitrogen content, takes in the ammonia nitrogen necessary for humification from the soil, resulting in a shortage of ammonia nitrogen necessary for plant growth. Invite starvation.

面保護の目的を達成できないという問題があった。[0005] Looking at the straw which is the foliage part of the grass family, this straw has a C / N ratio of 60 to 80 and a low nitrogen content, and if it is applied to the vegetation board as it is, nitrogen starvation is likely to occur. When straw is laid on unweathered soil such as cut slope, the humification of straw does not proceed because ammonia nitrogen is not supplied from the soil. Especially, the upper part of the straw that is not in contact with the soil has no supply of ammonia nitrogen,
Humus does not progress at all. As a result, the plants are not only deprived of the nutrients necessary for their growth, but are also unable to receive the required nutrients from the straws, causing the fertilizer to run out early and dying. The amount was limited to about 250 g / m 2 . In addition, grasses such as tall fescue, which plays a role of protecting slopes with fast rooting, deep rooting and soil tightness, require nitrogen especially, but it does not grow because ammonia nitrogen is lost to straw. There was a problem that the purpose of slope protection could not be achieved.

る。[0006] Therefore, in order to prevent a shortage of ammonia nitrogen, when it is conceivable to inject ammonia nitrogen fertilizer to the large amount of soil to the vegetation zones along with the seeds, to introduce 10g / m 2 or more in pure nitrogen amount of nitrogen There is a risk that the fertilizer causes the concentration of the plant to germinate when it germinates and die. In addition, if the amount of nitrogen fertilizer is increased and the amount of phosphoric acid and potassium is decreased, the germination growth is slower than that of gramineous plants, and woody plants such as yamahagi and flowering plants such as cosmos, which require phosphoric acid and potassium rather than nitrogen, grow. There is a problem that you cannot do it.

Maintenance costs are required as it is required several times a year, and it is necessary to consider adjusting the fertilizer concentration for new leaves and sprouts depending on the time of year. There's a problem.
