Core Viewpoint - The article discusses the challenges and solutions related to winter wheat planting in the Huang-Huai-Hai region of China, particularly due to delayed rice harvesting caused by continuous rainy weather. Group 1: Agricultural Challenges - The Huang-Huai-Hai region is a significant winter wheat production area in China, facing delays in rice harvesting due to prolonged rainy weather, impacting the planting schedule for winter wheat [1] - In Yuanyang County, the rice harvest has been delayed by nearly 20 days compared to previous years due to insufficient accumulated temperature, compressing the winter wheat planting window [5] Group 2: Technological Solutions - The use of drones for sowing winter wheat is being promoted, with plans to implement this technology by 2025, allowing for sowing 10 to 15 days before rice harvesting [8] - Advanced precision sowing machines equipped with Beidou navigation systems are being utilized to ensure accurate sowing and simultaneous fertilization [7] Group 3: Implementation and Support - In Huai County, over 1.8 million acres of winter wheat planting is progressing smoothly, with local agricultural departments organizing technical personnel to guide farmers on adjusting sowing depth and density based on soil moisture conditions [9] - The promotion of suitable late-sowing varieties and key technologies is being emphasized to ensure a solid foundation for summer grain harvests in 2026 [9]
