摘要
Pesticide packaging wastes pose a serious hazard to the agricultural production environment and the quality of agricultural products. The investigation for 2 consecutive years in Jietou Region of Tengchong County, a major tobacco planting area in Yunan, showed that： ① More than 80% of the pesticides purchased by farmers were used for tobacco cultivation, which was 4 times that of conventional crops planting, and most of the packaging materials were plastic bags; ② The main way for farmers to dispose plastic bags was to burn or discard them in the field garbage collection baskets; ③ In combination with field surveys, an average of 4.54 pieces of pesticide packaging wastes were scattered around every 667 m^2 of tobacco field. In addition, the number reduced significantly after carrying out pesticide packaging wastes recycling and control project at the local smoke station. At the same time, the average number of pesticide packaging wastes in the field collection baskets increased. Therefore, it can effectively control pesticide packaging wastes by changing the type of pesticide packaging, encouraging the establishment of recycling system and strengthening the cognitive training of farmers.
