摘要： 为进一步研究水稻恶苗病防控技术，减轻恶苗病的发生，笔者开展了不同播种方式、不同药液浓度和浸种时间对水稻恶苗病的防控效果试验。结果表明，不同品种间株发病率差异显著，早播比迟播发病严重，早稻比晚稻发病严重，采取不催芽或露白播种的处理比长芽播种的处理秧苗恶苗病病株率减少18.9%~21.5%。

Abstract: A field experiment was carried out to explore the prevention and control techniques of rice bakanae disease and reduce the occurrence of the disease. The results showed that there were significant difference about different varieties, sowing methods, solution concentration and soaking time on the control of rice bakanae disease. Compared to the long bud treatment, the bakanae disease rate of no germination sowing or white bud sowing treatment reduced by 18.9%~21.5%.
