Weather Characteristics and Agricultural Impact Analysis - This week (May 25-31, 2025), northern agricultural regions experienced temperatures close to or 1-2°C higher than the historical average, with some areas in the northeast and northwest exceeding 4°C above average [2] - Southern agricultural regions saw temperatures near or 1-2°C below the historical average, with certain areas in Jiangnan, South China, Yunnan, and southern Guizhou being 2-4°C lower [2] - Precipitation in northern regions ranged from 10-50 mm, while parts of Jiangnan, North China, and Yunnan experienced 50-100 mm, and some areas received 100-250 mm, significantly above the historical average [2] - Sunshine hours were generally close to historical averages, with some areas in northeastern Jiangnan and eastern Heilongjiang seeing increases of 30-80% [2][7] Agricultural Production Impact Analysis - In the northeast, favorable light and heat conditions benefited the growth of dryland crops and rice transplanting [8] - The northern winter wheat region had predominantly sunny weather, facilitating the harvesting of mature winter wheat, although rain from May 30 to June 1 may temporarily hinder harvesting in some areas [8] - In the southern regions, heavy rainfall led to flooding in low-lying fields, affecting crops like lychee and mango, while persistent rain hindered crop growth and pest monitoring [9] Future Weather Impact Forecast and Recommendations - The next ten days are expected to have suitable conditions for the growth of corn and soybeans in the northeast, while heavy rainfall in parts of Heilongjiang may cause temporary flooding [10] - Northern regions will experience mostly sunny weather, which is beneficial for harvesting winter wheat and planting summer corn, but high temperatures (35-38°C) from June 5-7 may disrupt wheat maturation [10] - Recommendations include managing dryland crops and water levels in rice fields, ensuring timely harvesting and planting, and maintaining agricultural water infrastructure in southern regions to mitigate flooding risks [11]

Core Viewpoint - The article discusses the current agricultural situation in Sichuan, focusing on the summer harvest and planting amid ongoing high temperatures and drought conditions, highlighting the progress and challenges faced by farmers in the region [3][4][6]. Group 1: Summer Harvest Progress - As of May 20, Sichuan has harvested 30.185 million acres of small spring grains and oils, nearing 80% of the total planted area [4] - Wheat, a key summer grain, has been harvested on approximately 6.2 million acres, accounting for two-thirds of the planted area, while rapeseed harvest covers nearly 2 million acres, representing 90% of its planted area [4] - The summer harvest is expected to conclude by the end of May, slightly ahead of previous years [4] Group 2: Summer Planting Progress - By May 20, Sichuan has completed the planting of 56.832 million acres of major summer crops, exceeding 70% of the planting plan [6] - Rice planting has reached 21.06 million acres, surpassing 75% of the planned area, while other crops like sorghum and spring soybeans have also met their annual planting targets [6] - If weather conditions remain favorable, Sichuan aims to complete summer planting by early June [6] Group 3: Weather Impact - The ongoing high temperatures and drought conditions have led to increased water requirements for newly planted crops, with some farmers reporting a 10-20% increase in water usage [7][8] - As of May 19, the Ministry of Water Resources has initiated a level IV drought emergency response for Sichuan due to the dry conditions affecting the northern basin and southern regions [7] - The drought has been classified with varying severity across 67 weather stations, impacting crop growth and necessitating additional irrigation efforts [7][9] Group 4: Mitigation Strategies - The Water Resources Department is closely monitoring drought developments and accelerating water management efforts to enhance irrigation supply [9] - Local authorities are advised to pay attention to weather changes and consider artificial rainfall to support soil moisture and crop planting [9]
