Weather Conditions During Summer Harvest and Planting - The overall weather conditions during this year's summer harvest and planting period are expected to be favorable, facilitating agricultural activities [3] - From late May, most summer grain-producing areas will experience mainly sunny or partly cloudy weather, with a low risk of continuous rain, which is beneficial for the maturity and harvesting of winter wheat and rapeseed [4] Potential Weather Risks - There will be a significant rainfall event in regions such as Jianghan, Jianghuai, and northern Jiangnan from May 27 to 28, which may adversely affect the harvesting of rapeseed and winter wheat [5] - The first half of June may see temperatures close to or slightly above the historical average, which is generally favorable for wheat harvesting, but localized severe convective weather may occur, necessitating precautions [5] - The risk of continuous rain and heavy precipitation during the wheat harvesting period is high in certain areas, while increased rainfall later will benefit summer planting efforts [5] Impact of Adverse Weather - Continuous rainy weather can lead to difficulties in harvesting, causing wheat to fall and spoil, and affecting the drying of harvested grains, resulting in yield losses [9][13] - "Rotting rain" typically occurs from late May to mid-June, caused by the convergence of cold air from the north and warm moist air from the south, leading to widespread and slow-moving rain systems [11][12] Recommendations for Farmers - Farmers are advised to optimize machinery scheduling to take advantage of good weather for harvesting, and to manage soil moisture effectively to prevent waterlogging [15] - For harvested wheat, proper drying and ventilation are crucial to prevent spoilage, and timely planting of summer crops like corn and soybeans should be prioritized based on weather conditions [15] High-Temperature and Drought Challenges - High temperatures and drought conditions are prevalent during this period, particularly affecting regions like Huanghuaihai, North China, Jianghuai, and parts of the Southwest [28] - Young seedlings are particularly vulnerable to high temperatures, which can lead to issues such as "burning" and "yellowing," potentially impacting growth and yield [30] Mitigation Strategies for High Temperatures - Farmers should implement timely irrigation and nutrient management to mitigate the effects of high temperatures, ensuring adequate moisture and nutrient supply to crops [32][33] - Installation of cooling systems in greenhouses and using shading techniques can help protect crops from extreme heat [33] Emergency Preparedness for Weather Extremes - The Ministry of Agriculture emphasizes the importance of monitoring for drought, dry hot winds, and continuous rain, and encourages timely warnings and resource preparations to address potential disasters [42]
