| Abstract: |
| Leaves are in direct contact with the environment, making them more sensitive to air pollutants. Leaf apparent symptoms are typical symptoms caused by air pollutants that can be used as an indicator of air pollutants and help determine the extent of damage. This paper combs the differences in apparent symptoms, which is the expression of five typical air pollutants damage to crop leaves, and distinguishes the characteristics of leaf symptoms. In this paper, we reviewed the characteristics and differences of the apparent injury symptoms of crops damaged by five typical air pollutants, proposed ideas for identifying air pollutants through leaf apparent symptoms and specific identification techniques, and was applied to typical cases of mango damage identification in Tiandong County, Guangxi Province. Studies have shown that recognition technology for leaf apparent symptoms can identify pollutants quickly and effectively, narrowing the range of investigation and locking pollution sources. It is an intuitive, convenient, easy-to-operate, low-cost, and practical pollution damage identification technology that can provide technical support for non-professionals and administrative law enforcement personnel to quickly find and lock the source of harm. |
