Degradable liquid film prepared by adopting wastes of tobacco fields and use method of degradable liquid film

Abstract

The invention discloses a degradable liquid film prepared by adopting wastes of tobacco fields and a use method of the degradable liquid film. The film comprises the following components in parts by weight: 82-97 parts of raw material, 17-25 parts of film-forming agent, 3-4 parts of plasticizer, 1.1-2.15 parts of crosslinking agent, 0.03-0.05 parts of initiator and 0.1-0.2 parts of pH (potential of Hydrogen) regulating agent, wherein during dilution spraying, 0.1-0.2 parts of microelement fertilizer and 0.01-0.05 parts of botanical disease-preventing pest-controlling medicament can be added; and the raw material comprises one or more of fermenting waste liquor of the wastes of the tobacco fields, lignin sulfonate, modified starch, humic acid and carboxymethyl cellulose. The film disclosed by the invention is simple in process, safe and friendly to environment, lasting in effect, convenient to use and low in cost and labour intensity and has the advantages that the wastes of the tobacco fields are turned into treasure; the produced liquid mulching film has no adverse effect on crop growth environments such as soil underground water and soil; after the film is degraded, the organic content of the soil can be increased, the granular structure of the soil is improved and the soil-borne disease is inhibited; and the film formed after spraying is strong in ground adhesion and has a good heat preserving effect and moisture preserving effect.

Description

technical field [0001] The invention relates to the technical field of mulch film applied in agriculture, in particular to a degradable liquid film prepared from tobacco field waste and a use method thereof. Background technique [0002] Tobacco is an important economic crop in my country and an important source of income for the state and local taxation. Tobacco areas in my country are mostly distributed in poor mountainous areas with relatively backward economy. Tobacco planting is an important way to help farmers in mountainous areas get rid of poverty and steadily improve their living standards. Some, including tobacco stems, tobacco roots, bottom leaves, leaves optimized by the "optimized structure" policy, fireworks, tobacco seeds, axillary buds and other tobacco field wastes, have caused reduced soil productivity and frequent disease occurrence in tobacco fields. This has led to a series of ecological and environmental problems with regional characteristics, resulting ...
