(57) [Summary] [PROBLEMS] To provide a mulching material for upland cultivation and horticulture that can prevent the plume caused by pests on the ground and underground by preventing the flow of wood vinegar liquid. SOLUTION: The rice basis weight is 50 to 150 g / m 2 , the size is 10 to 120 seconds, the air permeability is 120 seconds or less, and the density is 0.3 to 0.8 g / cm 3 , base length of 2.8 to 5.6 km, breaking length of 2.8 to 5.6 km, and light transmittance of 0 to 5% are imparted with extensibility of 5% or more by flute processing, embossing processing or crimping processing. 1-15% by weight of starch, 0.1-15.0% by weight of wood vinegar, 0.1-3.5% of polymer % By weight. |
