Photodegradable high-yield mulching and its producing method

The photoecological mulching film contains additive the same as those in available mulching film, resin with spectral range of 400-700 nm, and fluorescent agent in 0.01-0.5 wt% of the material. During its preparation, fluorescent agent and talcum powder in the ratio of 1 to 3-12 are prepared into di...

More Information
Summary:The photoecological mulching film contains additive the same as those in available mulching film, resin with spectral range of 400-700 nm, and fluorescent agent in 0.01-0.5 wt% of the material. During its preparation, fluorescent agent and talcum powder in the ratio of 1 to 3-12 are prepared into dispersant pigment, the pigment is mixed with ersin homogeneously, other additives are added before preparing 40-100 micron film in conventional process. The mulching film of the present invention can convert harmful and useless light to the photosynthesis of crop into useful light and make the spectrum of light transmitting the mulching identical with that of the photosynthsis of crop required. So that the mulching film can raise emergencer ate, reduce disease and raise yield of crop.
