Abstract

PURPOSE:To raise the germinative property of seeds in a seeds spraying work for plating greens on the slope of a bare ground by spraying resin films of an adequate size, together with a binder, on the seeded place. CONSTITUTION:In a greens plating work in which a 3-10cm-thick soil layer is provided on a soil-depleted soft rocky slope 1 and the seeds 3 of a plant in the soil 2 are germinated to grow the plant with stalk and leaves 5, a resin film 4 of a size of 1-3cm<2> is sprayed, together with an asphalt emulsion or a resinous binder, on the surface of said sprayed soil 2 in such a way as to exactly bond them to the undulatory surface of the slope. By this, the evaporation of moisture in the soil can be prevented and the germination of the seeds can be ensured more exactly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seed spraying method for greening bare slopes created by development work by spraying the seeds of plants and trees.

Until recently, soft rock slopes with little soil were sprayed with mortar to stabilize the slope, but due to aesthetic concerns, soil seed spraying is now used to spray earth and sand to a depth of 3 to 1Q cm. construction method is being implemented. However, the drying of the sprayed soil layer is quite noticeable, and the spraying method has not yet been established. However, on uneven slopes where grass cannot be formed sufficiently, the germinated grass often smothers and dies inside rather than budding. By spraying a resin film cut into pieces of 1 to 3 cm square meters together with an asphalt emulsion and a binder made of sugar bean, it can be applied to irregular slopes with many bumps and dryness. I've grown into a master of covering it in close contact with the skin.

This not only improves the germination of the seeds, but also prevents the evaporation of water in the soil because countless pieces of resin film overlap and adhere to each other. It also retains moisture between the layers, making it even more effective.
