In the countryside of Hefei today, the wheat waves are rolling and the melons and fruits are gradually ripening, full of the joy of harvest. In addition to the hard work of farmers, there is also the full support of scientific and technological forces.
In recent years, the city has given full play to the advantages of scientific and educational resources, focused on the top-level design and mechanism innovation in the field of agricultural science and technology, continued to strengthen key technical research and the transformation of scientific and technological achievements, and injected strong momentum into the high-quality development of agriculture and rural revitalization in the city.
How new technologies can help modern agriculture
Run out of "acceleration"?
The answer is in the test station,
In the agricultural valley,
On the field of hope...
Lujiang County facility agriculture - intelligent linkage greenhouse.
Write scientific papers on the ground
"Spring tea is worth a thousand dollars in the morning!" With the complete planting technology of experts from the Key Laboratory of Tea Science of Anhui Agricultural University, the spring tea in Lujiang County can now be listed half a month earlier than before, and many tea farmers have benefited from this.
Walking into the tea germplasm resource garden of the Annong Dawanzhong Comprehensive Experimental Station in Guohe Town, the ditch between a ridge of tea trees is full of rat thatch. These grasses do not grow naturally, but are deliberately planted by researchers.
"This is the tea garden to grass suppression promotion model, rat thatch is a cold-resistant but not high-temperature resistant herbaceous green manure plant, the root system is not developed and not high, will not compete with tea plants for nutrition." Yellowing in summer can play a role in cooling the soil, and in winter, the green and lush can be kept warm. Jiang Teng, a technician at the Anhui Central Comprehensive Experimental Station of the New Rural Development Research Institute of Annong University, said.
At the Annong University Production, Education and Research Base, the staff maintains tea saplings by "suppressing grass with grass".
In the field, the tea trees grow in front of you not only have rat thatch, but also a long black anti-grass film.
"This is also what we have selected and experimented many times, this mulch film is breathable, water-permeable, and protected, and can be used for five or six years." Jiang Teng said that before planting the tea plant, they also dug a 70-centimeter trench and sprinkled organic fertilizer to improve the quality of the tea. This complete set of technology was promoted and applied to large tea growers in Lujiang in 2019, and the planting area has now reached 60,000 to 70,000 mu.
Write scientific research papers on the ground and apply scientific and technological achievements to practice. Focusing on the leading industries in Lujiang, the Anhui Central Experimental Station has established six major industrial alliances of high-quality rice and wheat, characteristic fruits and vegetables, famous tea, economic forests, special aquatic products, and agricultural product quality and safety, and carried out extensive research.

The data shows that since 2017, the station has introduced, screened and cultivated more than 890 new varieties, demonstrated 96 new agricultural technologies and new models, has 12 invention patents, and established, formulated and issued 97 standards/technical regulations. In 2019, the station achieved the highest rice yield in Anhui, reaching 1053.7 kg.
It is better to teach people to fish than to teach people to fish. The station undertakes 10,000 students and business entities internship training every year; promotes 1,000 college students to engage in innovation and entrepreneurship activities; and trains 200 outstanding agronomics and new farmers.
"Agricultural Valley" makes fertilization plant protection smarter
The people take food as the sky, and food takes safety as the first.
Citizens buy fruits and vegetables, whether pesticide residues, heavy metals, and antibiotics exceed the standard cannot be detected by the naked eye. In the Hefei Smart Agriculture Valley of Changfeng (Shuangfeng) Economic Development Zone, a visual test paper for pesticide residues has been successfully developed and will be put on the market soon. In the future, consumers will use this test strip to gently rub the appearance of fruits and vegetables, and then use fluorescent lamps to illuminate the test strip to know its safety status.

"Under normal conditions, the test strip is pink under fluorescent light illumination, once it exceeds the standard, it will become blue, and the darker the blue, the more serious the excess! Traditional testing requires instruments and is more expensive, while test strips are not only cheap to carry but also convenient. In the laboratory, researcher Li Lingfei said while demonstrating that they are developing fluorescent lamps and mobile phone APP with relevant mobile phone vendors to make detection more convenient and the parameters more accurate.
Niu Runxin, deputy general manager of Hefei Smart Agriculture Valley, introduced that in the future, all Changfeng strawberry packaging boxes will be equipped with this test strip. "Nowadays, the brand value of Changfeng strawberries exceeds 7 billion yuan, how to reflect the high quality? Consumers can get a glimpse through test strip testing! Niu Runxin said that for the strawberry agricultural valley is building a Changfeng digital strawberry big data platform, set up industry overview, production process management, quality management, market circulation and other information in one, to help the industry bigger and stronger.
The technicians of Zhongke Hefei Smart Agriculture Valley use the intelligent robot of soil testing to do soil testing.
"We have access to 5 strawberry farms, the platform can monitor the greenhouse planting environment, water and fertilizer environment in real time through sensors, and give growth parameters and guidance through big data analysis, so that the strawberry fruit rate is higher and the taste is better!" In addition, the platform enables full traceability of strawberry quality. Gao Jun, a staff member of the Smart Agriculture Valley Integrated Innovation Center, said.
"Anhui and Hefei have many cutting-edge technologies in the original innovation of smart agriculture and strategic emerging industries. The municipal government and the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences jointly built the 'Smart Agriculture Valley', focusing on the application scenarios of smart fertilization, smart plant protection, and smart quality control, building a core technology system, product system, and standard system of smart agriculture, and forming a number of domestic first-class and international leading core technologies and products. Our goal is to form a trillion-level smart agricultural industry ecology. Niu Runxin introduced that the Smart Agriculture Valley has introduced 5 talent teams and gathered 153 scientific researchers to devote themselves to the research and development and industrialization of smart agricultural technology and equipment.
