Problems solved by technology

The ultra-thin mulch is easily damaged, but it is not easy to decompose. It takes time and effort to recycle, and it takes 1hm to recycle 2 The residual mulch takes 8 days for one person to complete
The price of the recycled plastic film is very low, and most waste recycling stations do not recycle the residual plastic film at all, resulting in poor economic benefits of recycling the residual plastic film
Therefore, the enthusiasm of farmers to voluntarily recycle the residual plastic film is not high. In most cases, the residual plastic film that is naturally turned out of the ground is piled up on the field during farming, or burned

Abstract

The invention relates to a method for quickly decomposing a residual mulch. A device related by the method consists of a vehicle-mounted platform, a controller, a microwave generator, a matching load, a circulator, a rectangular wave guide, a shielding device, a horn port surface wave guide and a mulch; when the residual mulch is decomposed, a microwave absorbing material is added; coke powder, silicon carbide powder and ferrite are firstly prepared as solution according to a conventional method for spraying on the residual mulch; or in the mulch production process, the microwave absorbing material is added, and the device is used for quickly decomposing. During operating, the controller in the device is firstly started; the microwave generator is started through the controller; meanwhile, the height from the horn port surface wave guide to the ground is adjusted; the mulch is radiated through microwaves generated by the microwave generator; the microwave absorbing material in the mulch quickly absorbs microwave energy; under heat effect and microwave chemical effect, the mulch remained on the ground is decomposed; and the advancing speed of the vehicle-mounted platform is adjusted according to the microwave radiation power, so that the safe, efficient, continuous and fast decomposition of the residual mulch is realized.

Description

technical field [0001] The invention relates to a method for rapidly decomposing residual plastic film. Background technique [0002] Plastic film mulching technology has been widely used in my country's agricultural production. Plastic film mulching has the functions of increasing ground temperature, preventing drought, waterlogging, disease and insect resistance, weed suppression, salt return prevention, soil compaction prevention, and nutrient loss prevention. It has a significant effect of increasing production, increasing the yield of grain per unit area by 20%-30% in a large range, greatly improving the yield and quality of crops, and realizing the change of crop production in most areas of my country, from one season a year to two seasons a year Even for more than a year, mulching technology has made outstanding contributions to ensuring my country's food security and agricultural modernization. [0003] According to the survey data, the promotion area of ​​mulching cu...
