China News Agency, Changsha, March 26 (Fu Jingyi) In March, Hunan, China's main grain producing area, empowered spring ploughing with high technology, accelerated the development of smart agriculture and smart agricultural machinery industry chains, and ensured stable grain production.

　　In Wangcheng District, Changsha City, there is an "unmanned farm" of more than 200 acres. Using new technologies such as the Internet of Things, big data, and artificial intelligence, a mobile phone is used to remotely control farm facilities and machinery, or intelligent equipment and robots make autonomous decisions. , operation, to achieve full coverage of farming, planting, management, and harvesting production links.

　　In the ZOOMLION Smart Agriculture Demonstration Base in Wharf Village on Yuanjiang River, the seedling seedling seedling planter has also been moved to the field ridge.

This machine is specially designed for orderly throwing seedlings. It cooperates with the precision seeder and high-strength soft plug tray. All processes from seedling tray conveying, sowing to soil covering and watering can be automatically and accurately operated.

　　"Through the data analysis of the 'ZOOMLION Zhinong Cloud' APP, the most accurate seed dosage can be given." said Wang Lei, agronomist at the Yuanjiang Smart Agriculture Demonstration Base of Zoomlion. Nearly 30,000 seedling trays are made, and the root system of the cultivated seedlings is independent, complete and developed, and it can be used with a seedling thrower to turn green quickly.

　　Next to this seedling field, there are also fashionable small buildings with solar panels, weather stations and other equipment erected. With various sensors in the fields, the weather, soil strength and insect conditions of the base can be seen at a glance on the APP.

Through satellite remote sensing, technicians can connect with smart agricultural machinery such as multi-spectral drones and unmanned rice throwers at home, and operate accurately.

　　Statistics show that Hunan produces 4.5% of the grain with 2.8% of China's arable land, and the area and output of early rice ranks first in the country.

In 2022, Hunan will ensure that the sown area of ​​grain will remain stable at more than 71.35 million mu and the output will be more than 60 billion catties.

　　"The 1,200-square-meter special plant for raising seedlings will provide machine-transplanted seedlings for more than 10,000 mu of paddy fields." In Leyuan Village, Yuanjiang City, the hinterland of Dongting, a modern greenhouse is also filled with green seedling raising trays.

Cheng Legen, the technical director, observed the process of drug spraying by the automatic sprayer. The circular motion seedling raising equipment, which are arranged in a tall order, circulates up and down to fully irradiate the seedlings.

　　Modern centralized seedling raising is not only of great benefit to early rice seedlings to avoid the "cold spring" and improve their quality, but also to reduce the labor intensity and production costs of farmers.

Cheng Legen said that from seed soaking to promote germination, high-speed seeding line sowing, to germination in closed room stacking trays, and seedling cultivation, it is all "pipeline" production.

"Intensive and large-scale production saves labor, land and cost."

　　In preparation for spring ploughing, Hunan has arranged for 13.5 million mu of early rice seedlings to be intensively reared this year, an increase of 3.5 million mu from last year, and organized 74 research and guidance groups to go to key early rice production counties to provide on-site guidance services.

　　At the same time as "smart farming", the new generation of farmers in Hunan also use high technology to stabilize the quality of food.

Ziyang District of Yiyang uses the self-developed precision lime spreader and rotary tillage integrated machine to protect the farmland base, simultaneously adjust the soil pH, soil testing and formula fertilization to improve soil fertility.

Zhong Qing, a major grain grower, said, "Formulated fertilizer is more 'appetite' to farmland."

　　The development of green manure cultivation such as vetch and rapeseed for fertilizer is also a soil improvement method explored by large grain growers in Hunan.

Liu Zhihua, a major grain grower in Niutouwan Village, Qiyang County, Yongzhou, said that the cultivation of natural and organic green manure not only reduces the use of 30% of chemical fertilizers per mu of land, improves the quality of rice, but also attracts tourists to the countryside for tourism, with obvious economic and ecological benefits.
