摘　　要：以超级杂交稻组合中浙优1号为试验材料，进行不同移栽密度和方式的试验。结果表明，在中等肥力水平条件下，产量以插秧密度为13．5～18．0万丛／hm^2，单本、正方形移栽方式的叶面积指数大，干物质积累高，群体结构合理，能提高纹枯病的抗性，增产效果显著。The different transplanting patterns on grain yield and disease resistance of super hybrid rice （Zhongzheyou 1 ） were investigated in farmer＇ s fields and in the experimental fields of Taizhou institute of agricultural science in Linhai city of Zhejiang province. The results indicated the grain yield and its components had significant difference between various trans- planting patterns. The optimization of high-yield density was （13.5- 18.0）×10^5 hills/hm^2 by transplanting squarely, which was higher LAI and dry matter accumulation. This transplanting method increased significantly the resistance of rice sheath blight and grain yield.
