The invention relates to a high-strength diffuse light and dust-proof greenhouse woven film and a preparation method thereof. A polyethylene plastic greenhouse woven film is of a three-layer compositestructure and comprises an outer layer, a middle layer and an inner layer which are sequentially arranged from outside to inside, the outer layer and the inner layer are high-pressure low-density polyethylene cast film coating layers, and the middle layer is low-pressure high-density polyethylene woven cloth. The high-strength diffuse light and dust-proof greenhouse woven film has the advantagesthat the prepared plastic woven film has a three-layer composite structure, and the middle layer high-strength woven cloth ensures that the woven film is high in strength, good in weather resistance,difficult to tear and long in service life. An inner layer is anti-fog and anti-drip, it can be ensured that the film cannot be decomposed in a casting coating high-temperature state and the anti-dripand anti-fog effect can las
