摘  要:为研究在减量施肥条件下生物有机肥对水稻产量和抗病性的影响,2022年—2023年在锡场谭蔡水稻种植基地开展了不同施肥条件下水稻的试验。结果表明,与对照组相比,在T3(施用有机肥2000 kg/hm^(2))和T4(施用有机肥2500 kg/hm^(2))处理下水稻的整体性状和产量最优,具有明显的显著性。此外,增加生物有机肥有助于提高水稻的抗病性,随着生物有机肥的增加,水稻抗病性也增强。In order to study the effects of bio-organic fertilizer on rice yield and disease resistance under reduced fertilization,rice experiments under different fertilization conditions were carried out at Tancha Rice Planting Base in Xichang from 2022 to 2023.The results showed that compared with the control group,T3(2000 kg/hm^(2) application of organic fertilizer)and T4(2500 kg/hm^(2) application of organic fertilizer)treatment had the best overall character and yield,with obvious significance.In addition,the increase of bioorganic fertilizer was helpful to improve the disease resistance of rice,and the disease resistance of rice was also enhanced with the increase of bio-organic fertilizer.
