摘要
为探究不同药剂对水稻稻曲病的防治效果,以安徽淮南市潘集区为试验地,考察药剂对水稻稻曲病的防治效果。试验结果显示,不同药剂处理均对水稻稻曲病产生了良好的防治作用。其中,防治效果最好的为N5处理,该处理防治效果超过80%,其次为N4与N2处理,防治效果均超过70%,N3处理防效最低,仅为63.40%。不同处理的水稻产量具有显著差异,其中N5处理的水稻产量最高为9 973.15 kg/hm^(2),显著高于其它处理,较对照(CK)提高了9.07%,不同处理的水稻稻曲病防治效果与产量均表现为N5>N4>N2>N1>N3>CK处理。因此,N5处理对水稻稻曲病防治效果最佳,且水稻产量最高;该结论为当地水稻稻曲病的防治提供理论依据。
This study investigated the efficacy of different agents against rice false smut(Ustilaginoidea virens)in Panji District,Huainan City,Anhui Province.All tested agents demonstrated effective disease control,with N5 treatment exhibiting optimal efficacy(>80%),followed by N4 and N2 treatments(>70%efficacy),while N3 showed the lowest control rate(63.40%).Significant yield variations were observed among treatments,where N5 achieved the highest yield(9973.15 kg/hm^(2)),9.07%higher than the control(CK)and significantly surpassing other treatments.Both disease control efficacy and yield followed the ranking:N5>N4>N2>N1>N3>CK.These results confirm N5 as the most effective treatment for false smut control and yield enhancement,providing theoretical support for local disease management strategies.
