AbstractThis research summarizedand analyzed the impacts of heavy precipitation weather on maize production， including its efects on maize growth and development，yieldandquality，as wellas the occurrence and prevalenceof pests and diseases，and proposed corresponding countermeasures.Heavy precipitation weather can delaythe growth and development processof maize，increase the risk of plant lodgingandleafdamage，and reduce grain yield and qualityby decreasing the numberof grains per ear and the thousand-kernel weight.It also affcts thecontent of starch and crude proteinin the grains，increases theimpuritycontent inthe grains，andraises therisk of pestand diseaseoccurrence and transmission.Based on these findings，the folowing countermeasures are proposed：selecting stress-resistant varieties; implementing scientific layout measures such as replacing crops with waterlogging-tolerant varieties inlow-lying areas， adopting ridge planting or wide-narrow row planting，adjusting the sowing date to avoid sensitive growth stages，and optimizing population structure to improveventilationandreduce humidity;strengthening field management，including timelydrainage，scientific fertization，and integrated pestmanagement；andenhancing support and safeguard measures.This paper provides a reference for enhancing the disaster prevention and mitigation capabilities of maize production and ensuring the safety of maize production.
