More Agricultural Research And Technology Competition, Science And Technology Into The Field Is The Future Of Agriculture

? ? ? The history of agricultural development is also the revolutionary history of agricultural technology. With the changes of population and land situation, new problems have emerged in agriculture, and technology has been constantly improving, which promotes the development of agricultural revolution. Today, how does technology face agriculture and how to help agriculture continue to write brilliance? The coming "Duoduo agricultural research and technology competition" has become an observable window.

Recently, pinduoduo, China Agricultural University and Zhejiang University jointly announced that the second "Duoduo agricultural research and technology competition" was officially launched. The competition will invite young agricultural scientific research teams from all over the world to join in the competition. By using the cutting-edge nutrition science and precision agriculture technology, the competition will challenge to grow high-quality and high-yield tomatoes within six months, and assess the key nutrient indicators. The total bonus pool of this competition is more than 1 million yuan, which will be used to support the winning teams.

What kind of imagination space will be given to agriculture by the exploration of young scientists and the next generation of farmers?

Changes in agricultural development

? ? ? ? Li Daoliang, a professor at China Agricultural University, pointed out in his book "no man farm", that the average age of the labor force engaged in agriculture is about 55 years old, with the post-60s and 70s as the main force, showing a cliff like age distribution. At most 25 years later, this generation of farmers will withdraw from the working scene, and the number of supplementary farmers will be less and less. It is a basic reality that the number of farmers will be greatly reduced in the future.

In fact, the proportion of agricultural workers in social workers in most countries of the world is on the decline. According to the public data, the proportion of agricultural workers / social workers in developed countries such as the United States, France and Japan is generally 3% - 5%, and the least country is Israel, about 0.9%. However, the proportion of agricultural labor force in the employed population is as high as 26.1%. With the departure of the previous generation of farmers, the urgent problem brought by the sharp drop of agricultural labor force is how to bear the demand of food supply in the future.

In recent years, mechanization, water conservancy, chemistry and electrification have gradually popularized in the field of agriculture, but compared with some developed countries, China's agriculture still has the problem of low efficiency. Agricultural experts pointed out that to solve these problems, we must vigorously develop intelligent agriculture with advanced technologies such as cloud computing, big data, Internet of things, artificial intelligence and other advanced technologies.

The iterative upgrading of agriculture has become the most important issue in China. This year, the No.1 document of the CPC Central Committee proposes to comprehensively promote the revitalization of rural industries, talents, culture, ecology and organization, especially to promote "significant progress in agricultural and rural modernization and agricultural infrastructure modernization to a new level".

Li Daoliang judged that in the next 30 years, China's agriculture will undergo great changes, and the leap from traditional agriculture to modern agriculture will also be realized“ Many agricultural research and technology competitions have explored artificial intelligence to solve the problem of human labor force. Next, we should encourage more social forces and scientific research institutions to join in, research and tackle key problems together, and truly promote the continuous progress of the industry. "

Examples of science and technology enabling agriculture

? ? ? Last year, pinduoduo and China Agricultural University jointly sponsored the first "Duoduo agricultural research and technology competition". Young agricultural scientists and top planting experts from all over the world were invited to form teams. With the help of advanced artificial intelligence or exquisite horticultural technology, pinduoduo challenged strawberry planting in Yunnan Plateau in four months.

In the process of competition, four AI teams and four traditional peasant teams played. In this competition of science and technology and experience, Ai Group uses AI technology such as crop growth model and convolution algorithm, while traditional farmers group relies on their own experience. However, no matter how different the means, the ultimate competition or strawberry yield, quality, input-output ratio and other indicators.

In the end, the average yield of strawberry in AI group was higher than that in traditional farmer group by 196.32%, except the difference of sweetness between AI group and traditional farmer group was 5.24%; The input-output ratio is 75.51% higher than the average value of traditional farmers.

It is worth mentioning that many teams participating in the agricultural research competition have begun to try to turn AI technology into real products, apply scientific research results to a broader field, and successfully start the exploration of commercial operation.

In June this year, Laozhang, a strawberry grower in Gulian village, Dianchi, Kunming, plans to install an automatic fertilization and planting decision-making system for his strawberry greenhouses during the summer fallow. After several investigations, we finally chose the local "little famous" zhiduoberry company to cooperate. Cheng Biao, head of zhiduoberry company, won the second prize in the first "Duoduo agricultural research technology competition".

After connecting to zhiduoberry digital agricultural service station, each strawberry plant pays 0.3 yuan of service fee a year. From October last year to the end of this may day planting season, Lao Zhang earned 30000 or 40000 yuan more than last year, and saved nearly 4000 yuan in fertilizer cost.

On the basis of the success of the first competition, this year's competition requires the global youth agricultural research team to use the cutting-edge nutrition science, precision agriculture and other technologies to challenge the cultivation of high-quality and high-yield tomatoes within six months, and conduct assessment on the key nutrient elements indicators.

Athletes need to use sensors, spectra, algorithm models, etc. to explore the cultivation of higher yield, higher quality crops. The competition will provide an independent greenhouse and corresponding environmental control application interface for the four teams entering the finals. The team can remotely adjust the water, fertilizer, light, carbon dioxide and other growth environment elements in the greenhouse to realize unmanned planting.

The final results will be determined by the expert team and the third-party laboratory, and the total bonus pool of this competition is more than 1 million yuan, which will also be used to support the winning teams.

Professor He Yong, Dean of the school of biosystems engineering and food science of Zhejiang University, said, "China's agricultural industry is undergoing great changes, and more new agricultural business entities will be created. At the same time, digital technology, cutting-edge agriculture and food technology will promote traditional agriculture step by step into the leading modern agriculture. We hope to encourage more scientific and technological forces to accelerate the development of China's agriculture through this competition. "
