摘　　要：以甬优2640和淮稻11号为试验材料,在淮安市稻麦示范基地开展钵苗机插稻高产攻关试验,同时以常规毯苗机插高产攻关方为对照,比较两种机插方式的产量构成及群体特征。结果表明,与常规机插稻相比,钵苗机插稻秧苗素质及大田移栽效果优势明显,群体茎蘖消长平稳;钵苗机插稻生育中、后期光合系统配置优,抽穗至成熟期物质积累量和积累比例高,2品种最终实产分别高5.87%和4.02%。In Huai＇an demonstration-base of rice-wheat, Yongyou 2640 and Huaidao 11 were used as materials by seeting the high-yield demonstration test of bowl-seedling mechanical transplanted rice, with conventional blanket seedling mechanical transplanted rice for CK, the yield and population characteristics under two kinds of mechanical-transplanting methods were compared. The results showed that, comparing with conventional blanket seedling mechanical-transplanting, the seedling quality and transplanting quality of bowl-seedling mechanical transplanted rice were all significantly better than the CK, the tillers presented the characteristics of rising steadily and dropping slowly. The photosynthetic systems of bowl-seeding mechanical transplanted rice were better than CK, and the accumulation and proportion of biomass were both significantly higher than CK from heading to maturity stage, the yield of two cultivars were 5.87% and 4.02% higher than blanket seedling mechanical transplanted rice respectively.
