On July 24, the "China Agricultural Green Development Research Association 2021 Annual Meeting and Member Representative Meeting and Agricultural Green Development Forum" jointly organized by the China Agricultural Green Development Research Association and the Institute of Agricultural Resources and Agricultural Zoning of the Chinese Academy of Agricultural Sciences was held in Beijing. Ma Youxiang, member of the Party Leadership Group and Vice Minister of the Ministry of Agriculture and Rural Affairs, attended the forum and delivered a speech. Yu Xinrong, member of the National Committee of the Chinese People's Political Consultative Conference and chairman of the China Agricultural Green Development Research Association, and Zhang Hecheng, secretary of the Party Group of the Chinese Academy of Agricultural Sciences, attended the event. Ye Zhenqin, Member of the Standing Committee of the Guangdong Provincial Party Committee, Peng Zhongyang, Director of Huawei Technologies Co., Ltd. and President of Enterprise BG, Wan Jianmin, Academician of the Chinese Academy of Engineering, Vice President of the Chinese Academy of Agricultural Sciences, and Professor Liao Hong of Fujian Agriculture and Forestry University delivered keynote speeches respectively.

        Mei Xurong, vice president of the Chinese Academy of Agricultural Sciences, released the "China Agricultural Green Development Report 2020" at the meeting. The reporting system reflects the overall level, major actions and important progress of my country's agricultural green development in 2019-2020. The report shows that my country's agricultural green development level has steadily improved. From 2012 to 2019, the national agricultural green development index increased from 73.46 to 77.14, an increase of 5.01%. First, the greening of agricultural production is steadily advancing. By the end of 2020, there were 5,479 valid agricultural industry standards. In 2019, the national environmental monitoring area of ??green food production areas reached 208 million mu, an increase of 32.4% over the previous year. The second is the coordinated development of agricultural resources and nutrition. In 2019, the national average grade of arable land quality was 4.76, an increase of 0.35 grades compared with 2014; the national farmland irrigation water effective utilization coefficient reached 0.559, an increase of 0.043 compared with 2012. Third, the environmental protection of agricultural production areas has achieved remarkable results. In 2020, the fertilizer utilization rate and pesticide utilization rate of the three major grain crops in the country will reach 40.2% and 40.6%, respectively, an increase of 5 percentage points and 4 percentage points compared with 2015; The comprehensive utilization rate has reached more than 75%, and the "white pollution" in key areas has been effectively prevented and controlled.

The penetration rate of sanitary toilets in rural areas across the country has exceeded 65%, the collection, transportation and disposal system of rural household waste has covered more than 90% of administrative villages in the country, and the treatment rate of rural household sewage has reached 25.5%. Fifth, experiments and demonstrations of agricultural green development were carried out in depth. The construction of the national important agricultural resource ledger system has initially achieved commercial trial operation, and completed the research and development of the government version of the agricultural resource sharing platform; 16 national long-term fixed observation and test stations for green agricultural development have been identified. The report also revealed new breakthroughs in the theoretical research on my country's agricultural green development in recent years, screened 10 regional agricultural green development technology integration models, summarized 10 typical cases of green agriculture, benefited agriculture and strong agriculture, and sorted out my country's agriculture from 2017 to 2020. Memorabilia of green development.

The "Agricultural Green Development Forum" focuses on major strategic, forward-looking and key scientific issues in agriculture, and conducts exchanges on the theoretical research, method system and key technologies of agricultural green development, and provides information for the main bodies of "government, industry, academia and agriculture" in agricultural green development. An important platform for colliding ideas and sharing results.
