Core Viewpoint - The article emphasizes the urgent need for coordinated efforts in Henan province to combat drought and ensure wheat production during the critical grain-filling period, highlighting the importance of timely irrigation and management practices [2][3][5]. Group 1: Drought Conditions - Since mid-March, Henan has experienced high temperatures and low rainfall, with average precipitation at less than 20% of the normal levels, adversely affecting wheat grain filling [2]. - As of May 8, 45% of soil monitoring stations in the province reported surface soil moisture deficits, with severe drought conditions affecting 20% of the area [2]. - The National Climate Center predicts continued high temperatures and low rainfall for most of May, necessitating further drought mitigation efforts [2]. Group 2: Coordinated Response - Various departments in Henan have mobilized to implement the provincial government's drought response strategies, focusing on irrigation and water resource management [3]. - A total of 19.76 billion cubic meters of water has been directed to 228 large and medium-sized irrigation areas, with 643,000 irrigation machines deployed to support drought relief efforts [3]. - The provincial government has allocated 500 million yuan in emergency drought relief funds, contributing to a total financial commitment of 4.66 billion yuan for drought mitigation and wheat production support [3]. Group 3: Expert Recommendations - Experts emphasize the critical nature of the current wheat management phase, likening it to a "100-meter sprint," where effective management can significantly impact yield [5]. - Key recommendations include preventing damage from hot winds, managing the risk of lodging due to drought-stressed plants, and controlling pest and disease outbreaks during the grain-filling period [5][6]. - Specific irrigation advice suggests that areas with adequate soil moisture should avoid watering, while drought-affected regions should irrigate around May 10 for southern areas and by May 15 for northern areas [6].
