目前农业生产采用塑料薄膜日益增多,但多为无色透明的,有色的尚少见广大农民对仃色薄膜的优点尚未充分认识。国内外实验证明,通过有色塑料薄膜改变光质以影响农作物的生产,一般都能起到增加产量和改善品质的效果。光对植物主要是进行光合作用。光合作用以太阳光为能源,由叶片从空气中吸收二氧化碳(CO_2)
At present, the plastic film used in agricultural production is increasing day by day, but most of them are colorless, transparent and non-ferrous, and the advantages of the majority of peasants on the Ding color film are not fully understood. Experiments at home and abroad have proved that changing the quality of light through colored plastic film can affect the production of crops and generally can increase the yield and improve the quality. Light is mainly photosynthetic plants. Photosynthesis to the sun as energy from the air by the leaves to absorb carbon dioxide (CO_2)
