摘　　要：在试验生态小区的土壤中,模拟长期使用稀土产生的积累以探讨稀土积累与水稻白叶枯病发生发展的关系。研究结果表明:0.5%,1%,3%,5%,7%,10%吸附容量和40g/亩的稀土以及土壤中2000g/亩和40g/亩的稀土复合肥添加剂对水稻白叶枯病发生后的病情指数影响无显著差异。Different accumulation of rare earth element (REE) for a long-term application was simulated in experimental plot soil to study the relationship between rare earth accumulation and rice leaf blightThe results indicated that REE accumulated from 05% to 10% of absorption capacity and 40g/mu had no remarkable effect on the disease index
