The present invention relates to a vegetation material for slopes intended to green the slope by applying it to the slope, and more specifically, a plant growth agent containing at least one selected from bark and peat moss and a urea-formaldehyde foamy substance. , relates to a vegetation material for slopes made of a vegetation base material consisting of plant seeds and cement containing superphosphate lime and turning it into mud by adding water. Seeds, fertilizers,
A widely used method is to spray a slurry-like vegetation base mixed with water and mixed with organic fiber curing agent onto the slope to preserve the soil. Protection by mortar spraying is also very common. However, with conventional construction methods, curing materials and seeds are often washed away by rain or wind after construction, and the formation of a vegetation layer is incomplete, making it completely impossible to green an existing concrete or mortar slope. It was hot. Previously, the present inventors mixed vegetation material consisting of urea-formaldehyde foam, plant seeds, and curing material with cement or mortar and water to create a slurry, especially for the purpose of greening concrete or mortar slopes. proposed a method of greening concrete and mortar slopes by spraying the concrete and mortar (Japanese Patent Laid-Open No. 1973
-118515) found through subsequent research that it is possible to green slopes using a composition containing a neutralizing agent that neutralizes the negative effects of cement, and it is believed that this will lead to a new development in this type of construction method. Summer. Previously, cement was thought to hinder plant growth due to its strong alkalinity or scum.
The present inventors have discovered that when a specific acidic substance, which is itself on the acidic side, is added to cement, it can neutralize the negative effects on plant growth caused by the strong alkalinity of cement or scum, and at the same time improve the pH of the entire composition. They have newly discovered that by slightly adjusting the amount, good results can be obtained for plant growth. That is, the present invention provides a vegetation growth agent containing at least one selected from bark and peat moss and urea-formaldehyde foam for the purpose of greening slopes, a vegetation base consisting of plant seeds and cement, and superphosphate lime. The present invention relates to a vegetation material for slopes which is made into mud by adding water. As shown in the examples below, the plant growth agent of the present invention uses a combination of at least one selected from bark and peat moss and urea formaldehyde slurry. It ensures water retention, air permeability, fertilizer retention, etc., and can be used in place of soil in small amounts even on steep slopes without soil, such as mortar or concrete slopes.
This will create an excellent vegetation base. Cement serves as a type of binder that allows the entire vegetation to settle on the slope. As already mentioned, it is originally not desirable to mix cement itself with plant seeds, but in order to neutralize the negative effects of its alkalinity, the present inventors added superphosphate lime, which itself is on the acidic side. This resulted in good results for seed germination and growth. Further, the amount used for the purpose of neutralizing the adverse effects of alkalinity in the mixture of vegetation materials may be 20 g/m 2 or less. The pH of superphosphate lime is 2-3. As mentioned above, the lime superphosphate contained in the vegetation material of the present invention is itself on the acid side, and if it were to be called a neutralizing agent, the neutralizing agent in this case would be the alkali of cement. Neutralization also has the effect of adjusting the pH of the slurry of the vegetation material composition to a state favorable for germination of plants. To produce the slope vegetation material of the present invention, a plant growth agent containing at least one selected from bark and peat moss and a urea formaldehyde foam;
After mixing plant seeds and cement and adding lime superphosphate, water is gradually added and stirred to form a highly viscous slurry base material. The ratio of cement in this case is determined by the angle of inclination of the slope on which the vegetation material of the present invention is sprayed, the amount of rainfall, etc., but the ratio of growth base material to cement is 5 parts by volume of cement. ~100 parts by volume, preferably 10 to 30 parts by volume of growth agent, to which 1 to 100 parts by volume, preferably 1 part by volume.
Add ~10 parts by volume of water and aim for pH adjustment of the slurry between 7 and 11. In order to use the vegetation material of the present invention prepared as described above by spraying it onto a slope, the high viscosity slurry-like base material is sprayed with a mortar spray gun, a screw type pump, a sand pump, etc. If sprayed on the surface, a coating layer will be formed. Preferably, the layer thickness is 0.5-10 cm. The present invention will be explained below with reference to Examples. Example 1 20 g/m 2 of seeds (Kentatsuki Huskew) were added to a mixture blended in the proportions shown in the table below, and water was added while stirring well to form a viscous substance.

Growth status test In order to confirm the effect of applying the vegetation materials obtained with the above composition on slopes, each No. of mud was pumped using a monopump through a conduit with a length of 20 m and a diameter of 5 cm. At that time, a pressure of up to 2.5 atmospheres (gauge) was required. It was sprayed to a thickness of 2 cm on a mortar surface with an angle of 45°. After construction, it was left outdoors, and even after several heavy rains, there was almost no washing away. The following table summarizes the growth status after construction.
