Currently, various regions are taking multiple measures to strengthen the management of autumn grain fields, enhance agricultural technology guidance, and solidify the foundation for a bountiful autumn grain harvest. The Northeast region is the main production area of autumn grain in China. At present, in Heilongjiang, corn has entered the tasseling and silk emergence stage, and rice is generally in the late stage of booting to heading stage. More than 8800 agricultural experts and technical personnel have been dispatched locally to strengthen guidance on field management for farmers. At Hongguang Farm of Beidahuang Group, foliar fertilizer is sprayed on fresh corn through a high gap spraying machine to improve the spraying effect. In response to the impact of rainfall in some areas, the Department of Agriculture and Rural Affairs in Liaoning has organized forces to conduct technical guidance on the front line of production, timely carry out pest control, fertilization and other work. This year, the autumn grain area in Henan is over 76 million acres. At present, corn in northern Henan has gradually entered the flowering stage, and some have started to fill the grain, which is a key node in disease and pest control. Henan Province has sent multiple autumn grain expert guidance groups to scientifically guide farmers to carry out "one spray, multiple prevention" and "one spray, multiple promotion" in a timely manner, and strengthen the monitoring and control of diseases and pests in autumn grain crops. Currently, rice in the middle and lower reaches of the Yangtze River is in the stage of jointing to booting. In Huai'an, Jiangsu, 4.8 million mu of rice is a critical period for water and fertilizer management. In order to improve precision fertilization of rice, the local agricultural science research institute has joined forces with Nanjing Agricultural University to promote unmanned aerial vehicle intelligent fertilization technology for rice, which saves labor and costs, promotes green and efficient farming, and increases production and income.
