摘　　要：通过对超高茬麦套稻的产量结构、源库参数等性状的测定分析，结果表明，超高茬麦套稻高产栽培应依据不同穗型，确定适宜的基本苗和N肥运筹措施，在大穗型品种单株成穗5个左右，穗粒并重型品种单株成穗4个以上，每公顷有效穗330万～360万时，群体综合性状最优。同时提出降低基本苗、调节肥水运筹等具体高产栽培技术措施。By mensurating the japonica rice yielding components and source-sink parameters the high yielding population for interplanting japonica rice with high wheat stubble would be reached based on the panicle types proper basic seedling and nitrogen fertilizers application. The best population were of 3.3-3.6 million productive tillers per hectare with about 5 productive tillers per plant to big paicle varieties and over 4 productive tillers per plant to medium panicle variedies.
