该农膜是一种光学性能优良的水稻育秧覆盖用薄膜,它是以太阳辐射和光生物学理论为基础,以水稻产区的气象和太阳辐射特征为依据,结合水稻秧苗生育期最适生物学需求而研制成功的。该薄膜在420～490nm和640～680nm 的红光处峰值透过率达85～
The agricultural film is a kind of film with excellent optical properties covering rice seedling cultivation. It is based on the theory of solar radiation and photobiological, based on the meteorological and solar radiation characteristics of rice producing areas, combined with the optimum biology of rice seedling growth period Demand and successful development. The film in the 420 ~ 490nm and 640 ~ 680nm red peak transmittance of 85 ~
