Xinhua News Agency, Hefei, April 5 Title: Scientific Grain Cultivation, Intelligent Mushroom Breeding, and Digital Fish Farming -- An Insight into the Transformation of a National Modern Agricultural Demonstration Zone
Xinhua News Agency reporters Jiang Gang and Shui Jinchen
"To improve the yield and quality of wheat, the key is to make a fuss about hiding grain in technology!" Standing on the edge of his own green wheat field, Xu Shuxiang, a major grain grower in Jiuxian Town, Taihe County, Fuyang City, Anhui Province, said that behind the dosage of seeds and fertilizers, there are "university questions" behind the dosage, not that the more they are used, the better, but to "make careful calculations" and grow grain scientifically.
At present, in the critical period of spring pipe spring plowing, the reporter came to the Taihe County National Modern Agricultural Demonstration Zone where Xu Shuxiang is located, where the wheat seedlings sway with the wind, a pot of cordyceps militaris thrives in the smart mushroom room, and flocks of fish jump up and down in the container...
Taihe County is located in the hinterland of the Huanghuai Plain, with 1.94 million mu of arable land, and the annual planting area of grain in the leading agricultural industry is more than 2.7 million mu, and the main varieties include high-quality wheat, soybeans, corn, etc. The planting area of vegetables, melons and fruits is 180,000 mu. In recent years, Taihe County to promote the development of rural industries as the starting point, around the industrial strong leader, strengthen the leading belt industry, in 2015 Taihe County whole county system was identified as the national modern agricultural demonstration zone, embarked on the road of industrial transformation.
Scientific grain cultivation is a major feature of spring pipe spring ploughing in the National Modern Agricultural Demonstration Zone of Taihe County.
Talking about hiding grain in technology, 69-year-old Xu Shuxiang pointed to reporters that using the method of precision sowing, one mu of land needs to sow about 25 kg of wheat seeds, while ordinary farmers need about 40 kg; using soil testing, formula fertilization and other methods, the amount of chemical fertilizer used in one mu of land is more than 40 kg less than that of ordinary farmers. "Input costs have declined, and the grain output per mu of land has reached 1,200 catties, which is about 200 catties higher than that of ordinary farmers, and the overall grain planting efficiency has improved."

The reporter saw in Anhui Bailu Modern Agricultural Technology Co., Ltd. that workers are nervous and busy, and in the smart mushroom room, pots of cordyceps militaris thrive. Dong Jianguo, the founder of the company, said that about 4 tons of fresh food and medicinal mushrooms (Cordyceps militaris, red bamboo thorns, etc.) are produced here every day, which are picked and packaged and transported to the Yangtze River Delta, pearl river delta and other regions, favored by consumers, and are currently in short supply.
"The staff can set the temperature and other indicators according to the growth of Cordyceps militaris, and can also view the ventilation, light and other conditions in real time to achieve intelligent cultivation." At the door of the Cordyceps militaris production workshop, Dong Jianguo pointed to a display screen and said that thanks to the support provided by the government in providing infrastructure facilities and labor coordination, the company has developed rapidly, and the smart mushroom room has increased from 110 last year to the current 210, with an output value of more than 100 million yuan last year, which is expected to double this year.

In addition to scientific grain cultivation and intelligent mushroom breeding, digital fish farming also reflects the scientific and technological content of the National Modern Agricultural Demonstration Zone in Taihe County.
In the Liangzhuang Agricultural Science and Technology Park, rows of blue containers and signs with the words "The whole process of breeding boxes simulates the natural ecological environment and returns the taste of your jianghu fish" are interesting. The reporter learned that here is a smart fishing ground, the container filled with water is the "home" of sturgeon, perch, crucian carp, etc., open the top of a container, and flocks of fish swim around in about 15 square meters of water.
So, where is the "wisdom" of smart fisheries? The reporter came to the digital control center of the smart fishery, where there is a digital fishery information management platform, where the indicators of water temperature, dissolved oxygen, ammonia nitrogen and so on are clear at a glance, and the growth status of fish can be monitored and managed in an all-round way.

"We simulate the living water cycle, using tailwater treatment, aquaculture wastewater utilization and other methods to create an environment suitable for fish growth, and achieve controllable and standardized production throughout the process." Chen Jinliang, head of Liangzhuang Agricultural Science and Technology Park, told reporters that compared with ordinary fish ponds, container farming of the same number of fish can save land resources and water resources of more than 90%, "This smart fishery has 70 containers, and can produce about 400,000 catties of fish a year." ”
Xu Gongxue, a member of the party group of the Taihe County Agricultural and Rural Bureau, said that in recent years, with the strong support of governments at all levels, the Taihe County National Modern Agricultural Demonstration Zone has strengthened the research of the green grain production increase model, implemented the green and healthy breeding mode of fishery, and carried out the green experience model of leisure agriculture, etc., and achieved initial results, "We are making every effort to build it into a national modern agricultural demonstration area that can be seen, learned, promoted and copied." ”
