降雨天气对夏收有何影响？该如何防范？一文了解

Core Viewpoint - The successful summer grain harvest this year is contingent upon navigating complex weather challenges, including high temperatures, heavy rainfall, and severe convective weather [1] Group 1: Impact of Weather on Wheat Harvest - Continuous rainy weather during the wheat harvest, referred to as "rotten field rain," can lead to wheat lodging and waterlogging, which increases the risk of mold and sprouting, adversely affecting both yield and quality [3] - If there is continuous rainfall of 1 millimeter per day for five days during the harvest, wheat may sprout in the field, and even harvested wheat can sprout if not threshed promptly [3] Group 2: Prevention Strategies - To prevent the effects of "rotten field rain," it is essential to monitor weather changes closely, adjust harvesting schedules based on wheat maturity, and ensure timely clearing of field drainage systems to minimize lodging [5] - Utilizing state-owned grain depots and school playgrounds for drying or airing wheat can help prevent mold during the drying phase [5] Group 3: Current Weather Conditions and Forecast - As of now, winter wheat in regions like southern Hubei and southern Henan is nearing maturity, with over 90% harvested in Hubei, while most winter wheat areas are still in the grain-filling stage [7] - The upcoming week is expected to have favorable weather for summer harvesting, with mostly clear conditions, although some regions may experience light to moderate rain [7] - Attention should be paid to potential rainfall events around June 1 in areas like Shaanxi, Henan, and Anhui, which could impact harvesting activities [7]
