AGRICULTURAL COVERING MATERIAL

摘要

The purpose of the present invention is to provide a highly uniform and appropriately air-permeable agricultural covering material, which sustains a high light transmittance so as to promote crop growth and enable a cultivator to visually monitor the inside thereof, allows the maintenance of soil temperature and thus exerts a good growth promotion effect, can prevent the excessive invasion of rainwater, shows no irregularity in strength and has good performance of preventing entry of harmful insects. The agricultural covering material comprises a non-woven fabric laminate, said non-woven fabric laminate having: (i) a light transmittance of 80% or higher; (ii) an air permeability within a range of 50-400 cm3/cm2/sec; and (iii) a weight per area within a range of 10-30 g/m2.
