First, take root in the front line of agricultural production, and write the paper on the earth to provide practical technology for increasing farmers’ income and sustainable agricultural development.
He has been engaged in the research on pollution ecology and soil ecology for a long time, actively researched and developed practical technologies that are in line with the actual needs of agricultural production, went deep into rural areas to carry out technical training and field guidance, improved the concept and level of farmers’ scientific farming, and carried out demonstration experiments on the application of continuous cropping diseases and soil degradation control technologies for typical crops according to the needs of farmers and agricultural enterprises in large-scale agricultural demonstration parks. It has made positive contributions to the sustainable development of agriculture and the increase of farmers’ income.
In view of the increasingly serious problems of soil degradation and quality and safety of agricultural products in China, the research group was led to deeply study the soil health problems in China, and an economic and practical ecological control technology system of green fertilization was developed. This technology breaks through the existing fertilization technology based only on crop demand, and initially establishes an ecosystem fertilization technology that meets both crop demand and soil biological demand. By enhancing the health and immunity of soil ecosystem, it improves the efficiency of nutrient absorption and utilization, and effectively inhibits soil continuous cropping diseases, thus significantly reducing the application amount of fertilizers and pesticides, improving the inherent quality of agricultural products and increasing farmers’ economic income.
Dong Yuanhua goes directly to the field for more than half of the days each year, and his trip involves more than 10 provinces. After six years of practice, the technical system can reduce the incidence of continuous cropping diseases from more than 20-80% to less than 10%, reduce the input of chemical fertilizers and pesticides by more than 20%, and increase the net efficiency by more than 1,000-5,000 yuan/mu in high-efficiency agricultural parks.
At the invitation of some local governments and Jiu San organizations, demonstration experiments on the application of green fertilization technology were carried out in view of the needs of farmers and enterprises in large-scale agricultural demonstration parks.
The application experiments in vegetable production in Jiangsu, Hebei, Xinjiang, Zhejiang, Hunan and other places can reduce the input of chemical fertilizers and pesticides by 20-50% per mu per season, reduce the incidence of continuous cropping diseases of vegetables from 20-80% to below 8%, and increase the net benefit above 1000 yuan. In 2010-2015, experimental demonstration bases of ecological regulation technology of green fertilization for vegetables were established in Suzhou and Changzhou respectively. The core demonstration area is 3200 mu. Cucumber, hawthorn, cowpea, small white gourd, corn, cauliflower, small green vegetables, cabbage, Chinese cabbage, etc. will increase production by 30-50% per mu every season, and the efficiency will increase by 1,000-3,000 yuan. In addition, in 2009-2015, demonstration experiments of green fertilization were carried out on vegetables in Jiangning of Nanjing, tomatoes in Donghai of Lianyungang, scallions in Xinghua of Taizhou, fragrant taro in Jingjiang of Taizhou and red taro in Jintan of Changzhou successively, and the net benefit per mu reached more than 1000 yuan. In addition to Jiangsu Province, from 2009 to 2013, demonstration experiments of green fertilization were carried out in wujiaqu city, Xinjiang, Chengde, Hebei, Changsha, Hunan and Haiyan, Zhejiang for large-scale intensive processing of tomatoes, carrots, potatoes, cabbage and Chinese cabbage, with a net increase of about 1000 yuan/mu. The application experiments of strawberries, apples, grapes, watermelons, walnuts, jujubes and other fruits were carried out in Jiangsu, Zhejiang, Xinjiang and other places. The soil health of degraded orchards was quickly restored, the quality was significantly improved, the pesticide consumption was reduced by 30-50%, and the net benefit per mu was more than 500-1000 yuan.From 2009 to 2014, green fertilization experiments were carried out in the strawberry bases in Donghai County, Lianyungang, Jurong, Yixing and Wangting, Suzhou. The picking period was about one week earlier, the amount of chemical fertilizer was reduced by 15-30%, and the quality of strawberries was significantly improved, with a net benefit of 3,000-5,000 yuan per mu. From 2010 to 2015, a green fertilization experiment was carried out in the degraded apple orchard in Fengxian County, Xuzhou. The average yield per plant is 175 kg, the increase rate is more than 50%, and the efficiency per mu is more than 5,000 yuan. From 2009 to 2013, demonstration experiments of green fertilization of grapes and peaches were carried out in Changzhou and Zhenjiang. The yield per mu increased by more than 1000 yuan, and the gummosis of peach trees was obviously controlled. In addition, in 2009-2013, demonstration experiments on green fertilization of grapes, yellow peaches and oranges were carried out in Nanhu District and Haiyan City, Jiaxing, Zhejiang Province, respectively, with an increase of more than 800 yuan per mu. In 2009-2011, demonstration experiments on green fertilization of melons and watermelons were carried out in Wujiaqu, Xinjiang, with an increase of about 300-500 yuan per mu. In 2011-2013, a green fertilization experiment was carried out in the intensive jujube and walnut production base in Aksu, Xinjiang. In 2012-2013, experiments on green fertilization of apples and peaches were carried out in Tianshui. In 2013-2015, the green fertilization experiment of citrus and pomelo was carried out in Gannan, and the yield increased by 12-18%.
From 2011 to 2015, the relevant technologies were transformed and applied to more than 40 kinds of cash crops in eight places in four provinces of Jiangsu, Hebei, Xinjiang and Jiangxi, with a total area of 261,200 mu and an additional economic benefit of 331 million yuan. The technical system has been authorized by national invention patents for 20 pieces.
Two, actively participate in the "100 experts to the countryside", actively spread advanced scientific concepts and technologies, and make positive contributions to establishing the brand of social service activities of the Jiu San Society.
According to farmers’ scientific needs, technical training and field guidance are carried out in rural areas every year, and grass-roots governments or agricultural professional cooperatives are cooperated in rural areas to train grass-roots administrative personnel and farmers on the concept and technology of green fertilization, so as to improve farmers’ concept and level of scientific farming. Actively participated in the "100 experts into the countryside action" of the Jiu San Society in jiangsu provincial party committee, and traveled all over Jiangsu Province, sending advanced, economical and practical technologies to farmers everywhere, and establishing 14 experimental demonstration sites for soil degradation remediation and green fertilization technology application in Changzhou, Suzhou, Taizhou, Xuzhou, Lianyungang and other cities.
Combined with the "100 experts into the countryside action" of the Jiu San Society in jiangsu provincial party committee, I used my research results to solve production problems, and conducted more than 10 training activities in Changzhou, Suzhou, Wuxi, Lianyungang, Xuzhou, Taizhou and other cities, and conducted dozens of field training instructions. For example, in March 2010, the training lecture on green fertilization of peaches in Luoyang town, Changzhou (210 people), in March 2010, the training lecture on green fertilization of vegetables in Xinghua, Taizhou (30 people), in October 2010, the on-site observation training on green fertilization of vegetable base in Xinyuan, Suzhou (100 people), in November 2010, the on-site consultation meeting on green fertilization technology of peaches in Jiangyin, Wuxi (40 people), and in 2010. On-site training on green fertilization of strawberries in Donghai County, Lianyungang in October 2010 (30 people), on-site training on green fertilization of tomatoes in Donghai County, Lianyungang in October 2009 (60 people), and lectures on green fertilization of vegetables and fruits in Jiangning, Nanjing in November 2009 (30 people). Lecture on Green Fertilization in Gushan Town, Jiangyin City in December 2011 (40 people). Soil health training in Jingjiang in April 2014 (30 people), soil health and green fertilization training for Malaysian fruit farmers in Zhangjiagang in April 2015 (30 people) and soil health training in Taicang in March 2016 (100 people).
In addition, at the invitation of the Jiu San Provincial Committee of Gansu Province, in November 2011, the apple production situation in Tianshui City was investigated, and more than 10 farmers were explained on the spot in the mountains. In the spring of 2012, they were invited to Tianshui to train fruit farmers on soil health and green fertilization (60 people). In the summer of 2012, at the invitation of Jiangxi Democratic League, we conducted an investigation on soil degradation in southern Jiangxi, and gave lectures on soil health to farmers and grassroots cadres (100 people).
Related activities have had a great social impact and have been well received by relevant local government departments, professional cooperatives and farmers. News media such as People’s Political Consultative Conference Daily, Tuanjie Daily, People’s Daily, China Political Consultative Conference News Network, CCTV 7, CCTV 2, Suzhou TV Station and Changzhou TV Station carried out special reports and reprints, which not only promoted the progress of farmers’ fertilization concept and technology, but also produced remarkable economic, social and ecological benefits, and played a positive role in the "100 experts’ action in rural areas" in 1993, which once again expanded the action of serving agriculture, countryside and farmers. Jiangsu Association for Science and Technology and jiangsu provincial party committee Agriculture and Industry Office of the Communist Party of China jointly awarded the "Outstanding Scientific and Technological Expert of Jiangsu Project for Promoting Agriculture and Enriching the People".
Three, actively participate in the discussion of state affairs, give full play to professional expertise, and submit high-quality proposals and information.
Actively participated in the political participation and deliberation work of the Provincial Committee of Jiu San Society, and wrote many proposals and information on soil pollution, resource development and utilization, efficient agriculture, energy conservation and emission reduction, which were adopted by the Central Committee of the Society and the Provincial Committee of the Society. In addition, he actively participated in the bidding topics and other research work of the Social Central Committee and the Social Provincial Committee, and was repeatedly awarded the advanced individual of the Social Central Committee and the Social Provincial Committee in participating in and discussing state affairs.
In 2003, the Social Central Committee launched the project bidding activity for the first time, combined with its own professional advantages and work accumulation, and submitted the project "Situation and Countermeasures of Soil Pollution in China" according to the national demand. After expert review, among 102 bids from 29 provincial organizations, 12 winning projects were identified, and this project won the bid. After winning the bid, under the direct leadership and support of the Social Provincial Party Committee, after more than three months of careful investigation and summary, the research task of this topic was completed on time, and the expected goal was achieved. The research report was submitted to the Social Center, and the proposal report and speech materials were drafted, which was adopted by the Social Center. The relevant proposal was submitted and delivered at the 2004 Chinese People’s Political Consultative Conference Conference, which was highly valued by the State Environmental Protection Administration, the Ministry of Land and Resources, the Ministry of Agriculture and other departments. The research report and achievements have been highly praised by Chairman Han Qide and other social centers, provincial party committees and leaders.
As the director of the Special Committee on Population, Resources and Environment of the Social Provincial Party Committee, he actively organized the Special Committee to undertake or participate in the research projects of the Social Provincial Party Committee. In 2014, the Special Committee independently declared and undertook the research project of the Social Provincial Party Committee, "Countermeasures for Further Improving Soil Pollution Remediation in Jiangsu Province", and formed a proposal of "Suggestions on Further Improving Soil Pollution Prevention and Control in Jiangsu Province", which was submitted to the Provincial Party Committee and adopted. On this basis, it also formed information such as "Further Strengthening the Protection and Supervision of Soil Environment", which was adopted by the Social Provincial Party Committee and the Social Central Committee and was rated as "2013-2013" by the Jiangsu Provincial Committee of the Chinese People’s Political Consultative Conference.
In addition, according to the characteristics of my own work, I submitted many pieces of information on the sustainable development of agriculture and the sustainable utilization of soil resources, which were adopted by the provincial party Committee and the social center. Among them, in 2011, the suggestion on the degraded orchards in Fengxian County of Xuzhou was approved by Li Xueyong, then governor of Jiangsu Province, and in 2014, the suggestion on soil health was approved by President Yu Zhengsheng and Vice Premier Wang Yang.
