摘　　要：选取‘荃优822’水稻作为研究对象,于安徽省滁州市明光市古沛镇开展药害试验。共设置6个处理以及清水对照,通过2次施药操作,测定水稻的生长指标和产量构成因素。结果显示,不同除草剂对水稻的株高、分蘖数、叶面积指数、叶色、有效穗数、每穗粒数、结实率、千粒质量以及产量等影响存在差异,处理2、5能有效提升水稻农艺指标和产量。本研究成果为水稻生产科学合理选择除草剂提供了重要的参考依据。This study selected the rice variety'Quanyou 822'as the research subject and conducted a herbicide damage experiment in Gupei Town,Mingguang City,Chuzhou City,Anhui Province.This experiment set up a total of 6 treatments.Two applications of herbicides were carried out to measure the growth indicators and yield components of the rice.The results showed that different herbicides had varying effects on plant height,tiller number,leaf area index,leaf color,number of effective panicles,grains per panicle,seed setting rate,thousand-grain weight,and yield.Treatments 2 and 5 effectively improved the agronomic traits and yield of rice..This research provides important references for the scientific and rational selection and application of herbicides in the rice production process.
