摘　　要：[目的]探讨滁州地区水稻旱青立病的发病原因及防控措施。[方法]进行田间调研及对文献资料进行综合分析,研究滁州地区水稻旱青立病的原因,并总结常用的防治措施。[结果]滁州地区水稻旱青立病表现为单株发病、单丛发病、丛间夹杂发病,籽粒发病时,病穗中也有零星结实正常的稻粒。主要致病因素为富砷或缺素,属生理性病害,也不排除其他致病因素的影响。在防治措施上应重施有机肥、轮作,白土田多注意病情变化、干干湿湿多烤田、注意微肥施用时期、分蘖末期和花粉形成期调整避开高温、改善水浆管理等。[结论]该研究可为水稻旱青立病的防治提供参考。[Objective]Etiology and control measures of rice dry qing-li disease in Chuzhou Area were discussed.[Method]Field research was conducted and literature data was comprehensive analyzed,the causes of rice dry qing-li disease in Chuzhou were studied,and commonly used control measures were summarized.[Result]Rice dry qing-li disease in Chuzhou manifested as plant disease,single-bundle disease cluster disease between the inclusions,grain disease,the disease also had sporadic strong ear of normal rice grain.The main pathogenic factors or the lack of arsenic-rich element belonged to a physiological disease,and did not exclude other risk factors.In the prevention and control measures should be re-organic fertilizers,crop rotation,white Tsuchida more attention to the condition changes,dry roast over wet fields,pay attention to micro-fertilizer application period,the late tillering and pollen formation stage adjusted to avoid the heat and improve water slurry management.[Conclusion]The study can provide a reference for preventing the rice dry qing-li disease.
