Problems solved by technology

[0006] However, the tobacco growth cycle is long, and the ultraviolet rays in the plateau area are strong, the temperature difference between day and night is large, and the environment is harsh. The general biodegradable mulch film cannot meet the needs of tobacco growth in the plateau area, and the tobacco leaves begin to break before they are harvested, hindering the growth of later tobacco leaves

Abstract

The invention discloses a fully-biodegradable mulching film for tobacco and a preparation method thereof. The mulching film comprises the following raw materials in parts by weight: 100-120 parts of poly(butylene adipate-co-terephthalate), 10 to 30 parts of polylactic acid, 0.1 to 3 parts of calcium carbonate, 0.1 to 2 parts of talcum powder, 1-5 parts of a compatilizer, 0.01 to 0.5 part of a slipping agent, 0.1 to 1 part of an anti-blocking agent, 0.01 to 1 part of an antioxidant, 0.01 to 0.5 part of an ultraviolet light absorber, 0.01 to 0.5 part of an anti-aging agent, and 0.1 to 1 part ofan anti-hydrolysis agent. The preparation method of the mulching film comprises the following steps: drying poly(butylene adipate-co-terephthalate) and polylactic acid, and adding the dried poly(butylene adipate-co-terephthalate) and polylactic acid into a stirrer for stirring; sequentially adding other raw materials while stirring, and putting the uniformly mixed materials into a feeding hole ofan extruder; cooling an extruded material, carrying out granulating, and drying the granulated material to obtain a modified material; and adding the modified material into a blow molding machine, andsuccessively carrying out molding, cooling and winding to finish the production of the mulching film. The mulching film meets the requirement of tobacco growth cycle in plateau areas, is completely degraded after being used, protects the environment and increases the yield and income.

Description

technical field [0001] The invention belongs to the technical field of biodegradable mulch, and in particular relates to a fully biodegradable mulch for cigarettes and a preparation method thereof. Background technique [0002] Flue-cured tobacco planting, as a popular industry that saves time and labor and has fast and reliable economic returns, is suitable for planting and development in many rural areas of our country, especially in the inland Southwest region where sea, land and air transportation conditions are extremely scarce. After the flue-cured tobacco is planted, the tobacco leaves are made into various cigarettes, which not only creates a large amount of tax revenue for the country, but also increases the economic income of local farmers and promotes the development of the local economy. [0003] Affected by the geographical and climatic factors in the southwest region, in order to make the flue-cured tobacco plants grow healthily and rapidly, the tobacco seedlin...
