Farmers don't wait. At present, the grass-roots cadres are working hard to ensure a good harvest of grain and other agricultural experts. What high technology is hidden in the farmland? How to rely on science and technology to increase production and income? Let's take a look at the science and technology in the farmland. Beidou helps smart agricultural machinery become a good helper for farming With the buzzing of the rotor, 10 plant protection UAVs passed at low altitude, and the atomized drugs fell evenly on the green wheat seedlings. Beside the wheat field in waigou village, Guyi Town, Xiangzhou District, Xiangyang City, Hubei Province, Ma Hongguang pointed to the mobile phone screen: "you see, the UAV equipped with Beidou system is much easier to use this year! The spraying is accurate and has no dead corner, which greatly saves the amount of water and pesticide." Ma Hongguang is the chairman of Xiangyang lvgufeng modern agricultural planting professional cooperative. He said that compared with traditional agricultural machinery, intelligent agricultural machinery has lower labor cost and more accurate operation. It has become a good helper for farmers to farm. "With the help of intelligent agricultural machinery, I won an order for 10000 mu of organic wheat this year." On March 8, farmers in Cangtou village, Zhaoxian Township, Wen County, Jiaozuo City, Henan Province sprayed herbicides with plant protection UAVs in wheat fields. Issued by Xinhua News Agency (photographed by Xu Hongxing) Reporters in many places saw that agricultural machinery with Beidou navigation system was a "rare thing" in the first two years, and this year has become a new intelligent equipment for agricultural machinery in many places. In duzhuang village, WANGU Town, Hua county, Henan Province, Du Huanyong, a large grain grower, said that with the help of Beidou system, the planter allows crops to be planted more neatly and can accurately realize hole sowing, which not only saves the amount of sowing, but also improves the operation efficiency. In Jianli, Hubei, Huang Xikou Town, the main rice planting professional cooperatives, chairman Bi Lixia opened the App on mobile phone, equipped with Beidou system of UAV, transplanter and so on, real-time flying prevention, rice transplanting operation at a glance. In Heilongjiang, the unmanned operation of a single production link has been successively applied in Seven Star Farm Co., Ltd. of Beidahuang group in recent years. Yu Tielong, a technician of Beidahuang intelligent agricultural machinery center, said: "this year, we will realize the unmanned operation of the whole rice production process for the first time on 15000 mu of land." The reporter learned from the Ministry of agriculture and rural areas that the precision and intelligence of agricultural machinery and equipment for spring tillage preparation this year is a major feature. By the end of last year, there were 600000 agricultural machinery and equipment with Beidou Positioning operation terminals in China, making farming more intelligent. Start with seeds and lay the foundation for a good harvest "There are experts' tips', the wheat planted is different!" On March 24, Miao zenghai, a farmer in Miaozhuang village, Hesha Town, Hanshan District, Handan City, Hebei Province, looked at the strong wheat seedlings and was happy. It turned out that Miao zenghai and Handan Academy of Agricultural Sciences had "climbed close". Handmai 19 and handmai 24 planted by Miao zenghai were new wheat varieties cultivated by experts of the Academy of Agricultural Sciences. "Handmai 19 is characterized by wide adaptability, high yield and stable yield, which has been popularized in three provinces of Hebei, Jinlu; handmai 24 is characterized by dwarf, large spike and lodging resistance, which is very popular in the central and southern part of Hebei Province." Introduction by Liu Baohua, head of Handan comprehensive experimental station of national wheat industrial technology system and researcher of Handan Academy of Agricultural Sciences. Miao zenghai is confident: "we plant improved wheat varieties, apply organic fertilizer, use the technology of the Academy of Agricultural Sciences, and produce high-quality wheat seeds. This improved wheat variety can sell 0.2 yuan more than ordinary wheat per kilogram." On March 24, farmers carried out the prevention and control of wheat scab in the modern agricultural demonstration base in Baihu Town, Lujiang County, Hefei City, Anhui Province. Xinhua News Agency (Photo by Zuo Xuechang) Improved varieties are the basis of high yield and harvest. Starting with "small seeds", all localities strive to meet the new needs of supporting agriculture. In the dark room seedling raising workshop, the technicians of Beidahuang group Qixing farm Co., Ltd. are testing the intelligent control system and data platform, and the rice sprouting will begin in a few days. The dark room can provide a constant temperature and humidity environment, creating the best growth space for rice seeds, and the germination time is shortened from seven or eight days to 48 hours. Grower Liu Yongbing told reporters that the rate of seedlings increased by about 5% and saved seeds. The new technology can also effectively avoid the impact of early sowing and low temperature on rice seeds and seedlings, and lay a foundation for disaster prevention and reduction, stable yield and increase in the later stage. "With this new technology this year, rice seedling raising will be at ease." Liu Yongbing said. Information from the Ministry of agriculture and rural areas shows that this year, we should speed up the popularization and application of fine grain and oil varieties and advanced applicable technologies, and improve the supporting and leading role of science and technology in stabilizing grain supply. At the same time, carry out seed market inspection and strictly control the seed quality to ensure the safety of seed production in spring. Preventing disasters and diseases and promoting yield and harvest The 50000 Mu high standard farmland demonstration area built in Shangshui County, Henan Province is not only equipped with automatic irrigation equipment to save labor in farming, but also a "black technology" to make Qiu Shouxian, a large grain grower, more worry-free. The common diseases of wheat are usually transmitted by spores. The spore information automatic capture and culture system in the demonstration area can capture and cultivate the spores in the atmosphere around the farmland at any time, and the machine will automatically upload the results to the background server. Local plant protection technicians feed back the evaluation and identification results to farmers through mobile app. Farmers can remotely dispatch prevention and control equipment through mobile phone and take timely measures to prevent diseases. With the support of science and technology, Qiu Shouxian can manage the scenes of plant protection, irrigation and pest control of more than 2000 mu of farmland through his mobile phone. Meteorological disasters, diseases and insect pests are the "stumbling block" for a bumper grain harvest. With the help of science and technology, all localities have made meteorological disaster early warning more precise and pest control more timely. On March 17, in Ningying village, Jiasong Town, Nanhe District, Xingtai City, Hebei Province, Meteorological Bureau staff and farmers checked the soil moisture in the wheat field. Issued by Xinhua News Agency (Photo by Zhang Chi) Near the wheat field of Keyou grain planting professional cooperative in Ningjin County, Hebei Province, UAVs are carrying out pest control and chemical weeding. Liu Yilong, the person in charge of the cooperative, introduced that the agricultural and rural Bureau of Ningjin County has built a crop pest monitoring station on the ground, which can monitor the seedling green, moisture content, disease condition and insect condition of farmland at any time, and predict the types and trends of pests and diseases. This spraying is implemented according to the suggestions of the county agricultural technicians. Ningjin County has also established 19 field meteorological observation stations, covering 1.09 million mu of farmland in the county, which can monitor and predict the changes of 10 meteorological elements such as field temperature, rainfall and ground temperature in real time, provide farmers with weather forecast and meteorological disaster early warning information services, timely guide farmers to carry out field management and help reduce the losses caused by meteorological disasters. Meteorological experts predict that from April to May this year, meteorological conditions are generally conducive to the later growth and yield formation of winter wheat. The reporter learned from the China Meteorological Administration that the early warning of meteorological disasters in the later stage will be further refined to villages and towns, spread to villages, households and people, and give full play to the role of the first line of defense for meteorological disaster prevention and reduction.
