一种新型农用薄膜的效能

EFFICIENCY OF USING A NEW AGRICULTURAL PLASTIC FILM IN VEGETABLE CULTURE IN PLASTIC SHED

在普通农用薄膜生产过程中,添加一种荧光稀土络合物,制成农用光膜。试验表明:它对阳光的透过率明显大于普通农膜,建棚后的棚温和棚内地温均有升高,从而促使棚内作物生长、早熟和增产,经济效益显著。

The agricultural fluorescent film was made by adding the fluorescent com- plexes of rare earth in common agricultural plastic film.Experiments indicated that its sun- light transmissivity was higher than that of common agricultural film.When it was made in- to a shed,the inside temperature and ground temperature under the shed all increased,this made vegetable crops grow and mature quickly and boost their production.The economical benefit was evident.
