Mulching film special for peanut production

Abstract

The invention relates to a mulching film special for peanut production and belongs to the field of agricultural production materials. The technology is a differential mulching film production technology, and is characterized in that a round ultra-thin film site with the radius of 2 cm is arranged at a peanut seedling emergence position, the film thickness is 0.002-0.004 mm, the peripheral area ofthe site is a thick film area, and the film thickness is 0.01 mm-0.02 mm. The joint of the round ultra-thin film and the thick mulching film of the mulching film is reinforced and the film is not easyto tear apart at the joint, so that the warming, weed-preventing and moisturizing effects of a thick mulching film area can be ensured. The round ultra-thin film site has two film types, namely a polyethylene ultra-thin film and a degradable ultra-thin film, the polyethylene film type is easy to produce and low in cost, and the degradable film type is relatively high in production technical requirement, relatively high in cost and high in environmental protection value. Compared with an original mulching film, the mulching film has the advantages that the environment is protected, peanut growth requirements are met, and mechanized and standardized production is facilitated.

Description

technical field [0001] The invention relates to a special mulch film for peanut production, which belongs to the field of agricultural production materials. Background technique [0002] Plastic film has made great contributions to my country's agricultural production, but it has also brought serious environmental problems. According to the survey, the residual rate of plastic film in the soil has reached about 30%, which has seriously affected the sustainable development of the soil and brought serious problems to agricultural production. Influence. The reason is that our country has used 0.004mm-0.008mm mulch film for a long time. This mulch film has a low cost of use, especially for dicotyledonous crops such as peanuts. It has good effects, but the film layer is thin and difficult to Recycling, for this reason, in 2018, my country implemented a mandatory standard of 0.01mm plastic film, but it also brought some problems.

Problems solved by technology

[0002] Plastic film has made great contributions to my country's agricultural production, but it has also brought serious environmental problems. According to the survey, the residual rate of plastic film in the soil has reached about 30%, which has seriously affected the sustainable development of the soil and brought serious problems to agricultural production. influences

The reason is that our country has used 0.004mm-0.008mm mulch film for a long time. This mulch film has a low cost of use, especially for dicotyledonous crops such as peanuts. It has good effects, but the film layer is thin and difficult to Recycling, for this reason, in 2018, my country implemented a mandatory standard of 0.01mm plastic film, but it also brought some problems. The dicotyledonous crop peanut is very sensitive to thick plastic film, and it is more difficult for seedlings to be unearthed after use, resulting in a large number of broken seedlings , The dead seedling phenomenon has seriously affected the development of peanut production
