技术领域technical field
本发明涉及一种农田土壤污染治理机械，尤其是一种热风加热式土壤清理消毒机械，属农业机械装备领域。The invention relates to a farmland soil pollution control machine, in particular to a hot-air heating type soil cleaning and disinfection machine, which belongs to the field of agricultural machinery and equipment.
背景技术Background technique
随着农业耕地的连年种植和地膜、农药化肥的大量使用，造成农田土壤板结、杂草多、残膜含量高和病虫害聚集，严重影响农业生产经济效益和可持续发展。因此，对农田土壤进行高温无害化消毒除污处理可以减少残膜对土壤的污染，消灭杂草和病虫害，减少农药的使用量，改善土壤结构，降低农业生产成本，从而有效保护农业生态环境。With the continuous planting of agricultural arable land and the extensive use of plastic film, pesticides and fertilizers, the soil compaction, weeds, high residual film content and the accumulation of diseases and insect pests in the farmland have seriously affected the economic benefits and sustainable development of agricultural production. Therefore, the high-temperature harmless disinfection and decontamination treatment of farmland soil can reduce the pollution of the residual film to the soil, eliminate weeds and pests, reduce the use of pesticides, improve the soil structure, and reduce the cost of agricultural production, thereby effectively protecting the agricultural ecological environment. .
目前，土壤污染治理主要集中在农田残膜回收方面，其治理方式以机械化回收为主。农田杂草和病虫害防治以人工除草和喷洒农药为主，但人工除草成本高，农药的大量使用会影响生态环境，危害人类健康。因化肥的使用和耕地连年种植引起的土壤板结问题目前还没有有效的治理方法。鉴于农业耕地土质状况和土壤环境不断恶化的现实，发明一种作业效率高，一次作业即可清理残膜、消灭病虫害和抑制杂草生长的机械装备对农业增产增收和保护农业生态环境具有重要意义。At present, soil pollution control mainly focuses on the recycling of farmland residual film, and the control method is mainly mechanized recycling. The control of weeds, diseases and insect pests in farmland is mainly based on manual weeding and spraying of pesticides, but the cost of manual weeding is high, and the extensive use of pesticides will affect the ecological environment and endanger human health. So far, there is no effective treatment method for soil compaction caused by the use of chemical fertilizers and continuous planting of arable land. In view of the fact that the soil quality of agricultural arable land and the soil environment are constantly deteriorating, it is of great significance to invent a mechanical equipment with high operation efficiency that can clean up residual film, eliminate pests and weeds and inhibit the growth of weeds in one operation. .
