Chongming is the largest rural area in Shanghai, with 1 / 4 of the city's forest land, 1 / 3 of the city's basic farmland, the largest rural area and the largest agricultural population in the city. It is not only an important "vegetable basket" and "rice bag" in Shanghai, but also the largest green agricultural development space in Shanghai. During the 13th Five -year Plan period, Chongming was selected as one of the first batch of national agricultural green development pilot areas. It continued to take green as the background, and focused on the development goal of "high technology, high quality and high added-value" of agriculture to build an urban modern green agriculture highland and a golden signboard of Chongming’s green agriculture.

Starting a green brand

The core of the green agriculture is green food. In order to promote the full coverage of green food, Chongming has made bold innovation in production mode with green certification as the starting point. In 2018, Chongming tried to grow rice without chemical pesticides and fertilizers for the first time. The rice provided by Chongming has received warm responses in the market, and it has gained widespread popularity by the public. Among them, Chongming Beihu Organic Agriculture Demonstration Base is one of the first batch of pilot enterprises for the rice without chemical pesticides and fertilizers. According to Shi Yuping, an official of the base, the rice is planted without chemical pesticides and fertilizers, and the manual weeding is adopted indeed. After three years of accumulation, the standard system has become more and more mature, and the product brands are becoming more abundant. This year, Chongming will increase the rice production without chemical pesticides and fertilizers from 10,000 mu to 30,000 mu, and increase the vegetables without chemical pesticides and fertilizers from 1,000 mu to 5,000 mu.

How to seek a larger market for high-quality green food has become the only way for development. According to Qin Qiuwei, chief of the industry section of the district agricultural and rural affairs committee, Chongming adheres to the development concept of "high technology, high quality and high added-value", adheres to the safest and most ecological development positioning, creates a regional public brand, becomes a shining business card of the world-class ecological island, and transforms Chongming's ecological advantages into development advantages. In order to build a characteristic brand of high-quality agricultural products, the whole district adheres to arrange production by sales, focuses on expanding online and offline sales channels, and promotes the "welfare factory" and the "farmer market"; In order to develop new agricultural formats, establish and expand the "C2B" customized agricultural new production and marketing connection mode, it connects with new retail enterprises such as Dingdong.com and Hema Xiansheng.com, continuously extends the industrial development chain and enhances the influence and reputation of Chongming’s agricultural products; Through the strategic cooperation with leading commercial enterprises such as Bailian Group, Chongming will accelerate the full entry of green agri-products into the Shanghai market with new business forms, new technologies and new industries, so as to meet the needs of Shanghai citizens for the upgrading of consumption of high-quality agri-products.

At present, the district has 8 geographical indication certification trademarks, 2 geographical indication protection products and 4 geographical indications of agricultural products. The "landscape" trademark of the regional public brands covers 6 characteristic brands of Chongming Superior Products, such as Chongming Rice and Chongming Qingshui Crab. The Chongming agri-products in large supermarkets and e-commerce companies are welcomed by customers.

The high technologies support

Advanced technology is also an essential condition for the green development of agriculture. Chongming actively explores the integrated application of new technologies such as internet of things, internet, big data and artificial intelligence in agriculture, and Chongming’s smart agricultural brain comes into being.

In the one-stop service green agri-materials store located in Gangyan Town, it is seen that the display interface of smart agricultural brain, which combines six information systems, including agricultural GIS geographic information system, green pesticide closed management and control system, intelligent agricultural machinery management and control system, intelligent identification system, agricultural industry chain’s intelligent management and control system and digital circulation system. It is reported that the intelligent control system records all farming behaviors through the camera set up on the agriculture base with no chemical pesticides and fertilizers, and generates intelligent traceability codes through background processing. After purchasing the rice products with chemical pesticides and fertilizers, customers can identify the whole process of production, processing and circulation by scanning the traceability code, in a bid to add a guarantee.

In the intelligent agricultural technology service interface, 5G smart cloud applet is also set up. When farmers are in the field, they can get remote online auxiliary diagnosis of rice diseases and pests thanks to big data and artificial intelligence, and they can put forward any questions in the process of agricultural production at any time. Agricultural technology guidance services are provided by municipal, district and town agricultural technicians through cloud guidance, field answers, etc., thus realizing online land management and control.

Last March, Cuiguanli Digital Agriculture Base was officially launched. Dozens of high-tech equipment such as unattended orchard robots, UAVs for surveying and mapping, large farm data display screens, integrated water and fertilizer irrigation facilities, weather stations, cameras, sensors and so on. As long as farmers clicked on their mobile phones, the integrated water and fertilizer facilities could start irrigation, and the agricultural production efficiency was continuously improved. The digital transformation of Chongming agriculture is in progress.

The world-class players help

The development of green agriculture is also inseparable from high-quality business entities. Over the past five years, Chongming has actively cultivated and built new agricultural business entities, certified 20 doctoral farms, evaluated 79 municipal farmers' demonstration cooperatives, 120 district-level demonstration cooperatives, evaluated 5 key leading enterprises in Shanghai and 25 key leading enterprises in Chongming.

Under the influence of the "spillover effect" of the flower expo, Chongming has strengthened global investment in precision agriculture in recent two years, focusing on introducing a group of world-class players to develop modern facility agriculture projects. A total of 14 major ecological agricultural projects, such as Zhengda Chongming 3-million Egg Chickens Farm Project and Hengda • Shanghai High Tech Agricultural Base Project, were introduced, and the cumulative fixed asset investment of agricultural projects exceeded 4 billion yuan. So far, Chongming Smart Ecological Flower Garden and Youyou Sino-Dutch Modern Agricultural Innovation Park have been completed and been put into operation, injecting a new power into Chongming’s agricultural brand.

In recent years, in order to promote the green development of agriculture, Chongming has followed the principle of sustainable development and creates an intensive and circular industrial space. Chongming has initiated the three-dimensional planting and breeding model of paddy field and the standardized technical model of "combination of planting and breeding", thus promoting the synchronous improvement of agricultural and ecological benefits. Meanwhile, focusing on the end of production, it has accelerated the formation of a closed loop for the resource utilization of agricultural waste, built and operated 33 intelligent centralized composting sites in 12 towns and townships, treated vegetable waste and served surrounding farmers; 37,000 mu of aquaculture water has been treated, and more than 7,600 mu of aquatic products have returned to the nature, so as to realize a virtuous cycle of ecology, production and life.

The all dung + straw project of Shanghai Electric, located in Huaxi Village, Luhua Town, has entered the final sprint stage. After completion and operation, it is expected to consume 35,000 tons of agricultural and forestry waste, process 73,000 tons of dung pollution, generate more than 5 million kwh of biogas power per year, and produce more than 30,000 tons of high-quality organic fertilizer per year, which can be used for 60,000 mu of paddy fields.

In addition, the district continued to pay attention to the source control of agricultural inputs, and the certification rate of green food in the district has reached 91.8%, striving to build a global green food island. It has been selected as one of the top ten examples of China's agricultural green development report for two consecutive years, and the agricultural green development index has ranked No. 1 in the leading area of agricultural green development.
