Abstract

The invention relates to a degradable mulching film for agricultural planting and a preparation method thereof. The degradable mulching film is prepared from the following raw material components in parts by weight: 30 to 45 parts of low-density polyethylene, 10 to 15 parts of degradable master batch, 10 to 15 parts of polyvinyl alcohol, 8 to 13 parts of phenol-formaldehyde resin, 4 to 6 parts ofstarch, 4 to 5 parts of dioctyl phthalate, 10 to 15 parts of ferrocene, 2 to 3 parts of polycarbonate, 2 to 3 parts of titanium white, 3 to 4 parts of sorbic acid, 20 to 25 parts of ethanol and 8 to 12 parts of de-ionized water. The degradable mulching film provided by the invention has the advantages of easiness of obtaining materials and high transparency; the degradable mulching film has certain air permeability and waterproof performance; the ground temperature is improved and the soil humidity is kept; the degradable mulching film has the effects of promoting seed germination and rapid growth of seedlings and inhibiting the growth of weeds, and strong toughness; the degradable mulching has long service time and can be degraded to reduce the environment pollution.

Description

technical field [0001] The invention relates to the field of mulch, in particular to a degradable mulch for agricultural planting and a preparation method thereof. Background technique [0002] Agricultural mulch is an important agricultural production material after seeds, fertilizers, and pesticides. Its application has brought a revolution to agricultural production and has made important contributions to increasing agricultural efficiency and increasing farmers' income. Agricultural mulch film is a product used in agricultural production to protect plants from water loss, improve water use efficiency, and improve crop growth environment and yield. In economically developed countries, the amount of agricultural plastic film accounts for more than 50% of the total amount of all agricultural polymer products. Commonly used agricultural polymers mainly include polyvinyl chloride, polyethylene, polypropylene and unsaturated polyester resins, etc., but these materials cannot ...
