AbstractRandomsampling，typical field investigation，and monitoring station monitoring methods were used to conduct wheat seedling conditionand soil moisture status inFunan County，Anhui Province from December 24，2024 to January3，2O25.The survey found that the overall wheatseedling condition in the study area was good，with first， second，andthridtypeseedlingareasof 4.40million，.O3million，and1.10millonhm2，respectively，acountingfor 51.6% ， 35.5% ，and 12.9% of the total wheat sowing area.The overall soil moisture in the research area was moderately deficit.The relative moisture content of the O-2O cm cultivated layer soil at monitoring points A and F was 67.12% and 60.70% ，the soil moisture is slightly low.Other monitoring points were moderately deficit.Based on this，field management measures such ascontrolling excessive growth and strengthening seedlings （mechanical suppression， combingseedlings，andspraying foliar fertilizersand chemical control regulators），supplementing soil moisture for seedlings （irrigating overwintering water to supplement soil moisture），preventing and controlling diseases，pestsand weeds（monitoring and timely applying targetedpesticides to prevent wheatsheath blight，tc.），and preventingcoldand freezing （spraying potassium dihydrogen phosphate+aminoethyl ester+humicacid water-soluble fertilizer1-2 days before the arrival of cold waves）were proposed to ensure the safe overwintering of wheat.This article provides references forimprovingwheat yield and quality in similar regions.
