GREENS-PLANTING WORK FOR SLOPED GROUND HARMFUL TO PLANT GROWTH

摘要

PURPOSE:To permit the planting of greens even on sloped ground harmful to plants by a method in which a slurry composed of a pH regulator or an adsorbent for sulfuric acid and a muddy material is charged into baggy materials to form a shidlding layer for harmful substances and base materials for greens- planting work are sprayed on the shielding layer. CONSTITUTION:A mixture of superphosphate of lime, organic materials as pH regulators or slaked lime, and mud is charged into flexible baggy materials having a high tensile strength and provided with a filter point (e.g., of nylon, polyester, etc.) to form mats 4. The mats 4 are fixed with anchor pins 6, and then base materials, e.g., fertilizer, fibers, soil improvers, seeds, etc., for greens- planting work are sprayed onto the mats 4 by a motor-driven sprayer to form a greens-planting base layer 5 on the mats 4. Where water springs, a water-permeable mat 3 is then laid. Since a shielding layer for harmful substances is formed by placing mats charged with pH regulator or sulfuric acid adsorbent and muddy material on sloped ground and plant seeds and base materials for greens-planting work are sprayed on the shielding layer in this way, the growth of plants are easily attained.
