The invention discloses a pomace humic acid fully degradable water-retaining film and a production method thereof. In the process, high-activity BHA is firstly produced by solid-state fermentation technology, and then the starch industrial waste residue of a biopesticide enterprise is used to produce a fully degradable water-retaining film. The process includes: (1) crushing of BHA raw materials, solid-state fermentation under the action of complex bacteria such as fungi (Trichoderma, Aspergillus niger), yeast (Aspergillus plana, Aspergillus polydotio) and so on; (2) Starch industrial waste residue Pretreatment, film-forming processing with highly active BHA and packaging storage. The BHA-highly active fully degradable water-retaining mulch film produced by this process is widely used and low in cost, which is not only beneficial to the natural environment protection of apple production areas or processing areas, but also conducive to moisture conservation and production increase of crops in severe cold and water shortage areas in western my country.
