Group 1 - Continuous rainy weather has made the autumn grain harvest and timely wheat sowing difficult, prompting various regions to take action to ensure proper sowing and agricultural production for the next year [1] - In Wucheng County, the autumn sowing work has been delayed by about 20 days compared to previous years, with efforts focused on ensuring timely and suitable conditions for winter wheat sowing [1] - Agricultural experts are advising farmers on the appropriate amount of organic and compound fertilizers to use, emphasizing the importance of soil moisture and sowing depth for late-sown wheat [1][2] Group 2 - In Lingcheng District, agricultural experts are actively providing on-site guidance for autumn sowing, including recommendations on sowing depth and fertilization techniques [2] - The use of various agricultural machinery is being promoted in Leiling City to enhance the efficiency of tillage and sowing operations, with a focus on the importance of good seed and method pairing [2] - Dezhou City has released guidelines for selecting late-sown wheat varieties, recommending high tillering and root development varieties that are resistant to wet conditions and low temperatures [3]

Core Viewpoint - Shandong province is experiencing significant rainfall, which is delaying the autumn harvest and affecting agricultural operations [1][7]. Weather Impact on Harvest - Rainfall on October 15 has forced a pause in the ongoing autumn harvest efforts, with further rain expected on October 17 [1]. - The average temperature is expected to drop by around 10°C due to the cold air accompanying the rain, which is unfavorable for soil moisture management [1]. Agricultural Response - The Shandong government has mobilized 31,000 drainage equipment units to address waterlogging issues in farmlands [3]. - Recommendations include using small excavators to dig drainage ditches and employing mobile pumping equipment for forced drainage [3][4]. Drying and Storage Solutions - High demand for corn drying has led to the suggestion of a "segmented drying method" to temporarily store wet grains before final drying [4]. - Local drying towers in Heze city are operating at full capacity, with some capable of processing up to 900 tons of corn daily [4]. Crop Management Strategies - With over 80% of corn harvested in five cities, the focus will shift to land preparation and sowing once weather conditions improve [7]. - Late sowing of wheat is anticipated, necessitating careful selection of high-yielding wheat varieties and adjustments in sowing rates based on soil moisture conditions [7][8]. Historical Weather Data - Since September, Shandong has recorded an average of 23.8 days of cloudy weather and 23.2 days of rainfall, significantly above historical averages [8]. - As of October 14, nearly 80% of monitoring stations reported soil moisture levels above 90%, with over 72 million acres of farmland experiencing excessive moisture [8].
