摘要:
PROBLEM TO BE SOLVED: To provide a crop sheet for preventing high-temperature injury not inhibiting growth of cultivated crops while preventing occurrence of high-temperature injury. SOLUTION: The crop sheet for preventing high-temperature injury is made of a cloth-like body formed by intersecting thermoplastic resin uniaxial stretching yarns with one another in all directions. The uniaxial stretching yarn contains tungstic oxide fine particles shown by the general formula, WOX(wherein 2.45≤x≤2.999), and/or contains complex tungstic oxide fine particles shown by the formula, MyWOZ(wherein M is at least one kind of element selected from among Cs, Rb, K, Tl, In, Ba, Li, Ca, Sr, Fe, Sn, Al and Cu, 0.1≤y≤0.5, and 2.2≤z≤3.0) and having a hexagonal crystal structure. The void ratio of the cloth-like body is 5-80%. COPYRIGHT: (C)2011,JPO&INPIT
