抗旱保供与时间赛跑 各地全力应对持续高温天气

Core Viewpoint - The ongoing drought in regions such as Henan and Anhui is significantly impacting autumn crop production, particularly for peanuts, corn, and rice, necessitating urgent irrigation measures to mitigate the effects of high temperatures and lack of rainfall [1][3][5]. Group 1: Impact on Crops - Affected autumn crops include peanuts, corn, and rice, with critical growth stages being adversely affected by the drought [3][5]. - In Henan, corn is particularly vulnerable during the flowering and grain-filling stages, leading to potential issues such as reduced pollen viability and poor grain filling [3][5]. - The average temperature in Henan reached 30.5°C in July, 3.2°C above the historical average, marking the highest level in 64 years, with 41% of monitoring stations reporting severe drought conditions [5][6]. Group 2: Regional Responses - In Henan, various measures are being implemented to combat drought, including the use of water-saving irrigation technologies such as spray irrigation, which can save 60% to 70% of water compared to traditional methods [6][10]. - Anhui has initiated multiple water diversion projects, including the transfer of 5.71 billion cubic meters of water to the Huai River basin to support agricultural irrigation [7][11]. - Local governments in both Henan and Anhui are mobilizing resources for irrigation, with efforts including the activation of electric pumping stations and the dredging of irrigation channels [10][13][14]. Group 3: Future Outlook - Weather forecasts indicate a potential temporary relief from high temperatures and drought conditions in Henan and surrounding areas, with expected rainfall in the coming days [11][14]. - Continuous efforts are being made to ensure water supply for irrigation, with significant amounts of water already diverted to support agricultural needs [13][18].
