AGRICULTURAL PHOTOSELECTIVE-TRANSPARENT NONWOVEN-FABRIC COVERING METAL, NONWOVEN-FABRIC COVERING MATERIAL, AND PLANT CULTIVATION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide agricultural photoselective-transparent nonwoven-fabric covering material having favorable light transmission, and shielding specific light quality over a long extensional-coverage period so as to control the growth of plants. SOLUTION: The agricultural photoselective-transparent nonwoven-fabric covering material has 78-90% of photosynthetically effective radiant transmission of the light of 400-700 nm, and has 0.92-1.00 of the ratio of photon flux transmission R of a red light of 600-700 nm to B of a blue light of 400-500 nm each based on the standard light source D65.
