Shandong has numerous largescale corn processing enterprises and is one of the fast-growing regions in China for deep processing of corn. The status of production and processing of corn in the major corn-producing areas of Shandong Province such as Dezhou,Liaocheng and Tai'an was investigated on the spot. It was found that the development of the corn industry in Shandong also has many problems,such as the mismatch between corn demand and production areas,the excessively small planting area of special corn and the poor communication between technology and demand,resulting in barriers in technology and raw materials in the production and processing links of corn and making it difficult to form a complete industrial chain system. According to the actual investigation,a highly efficient agricultural industry safety review mechanism was established based on the sound judgement of industrial safety to ensure the safety of the company's development,and at the same time,the interpretation and promotion of the strategy of going abroad was strengthened,so as to provide a full range of information services for corn processing enterprises and help to further develop and optimize the corn industry in Shandong.展开更多

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.展开更多
