摘　　要：超高茬麦田套稻基本苗的合理配置是获得高产的基础 ,扬州地区中籼杂交稻每公顷套播基本苗 45万～ 6 0万 ,中粳稻每公顷套播 90万～ 12 0万 ,有利于个体、群体兼顾协调 ,达到花后高积累 ,获得较高产量。合理的肥料运筹是获得高产的调节手段 ,中籼杂交稻每公顷施纯氮 2 2 5kg左右 ,中粳稻每公顷施纯氮 2 92 .5kg ,有利获得高产。施肥方法上麦田套稻肥料运筹分蘖肥 ,穗粒肥以 6∶4或The reasonable number of basic tiller and main culm was the base of high yield of interplant rice in field of wheat with super high stem.In Yangzhou region, to achieve higher yield, the number of basic tiller and main culm of medium japonica hybrid rice and medium indica rice should be 3~4×10 4 and 68×10 4 respectively. Reasonable nitrogen management was an adjusting method of achieving high yield. It was useful for high yield to use pure nitrogen 225kg/hm 2 in medium japonica hybrid rice and 292.5kg/hm 2 in medium indica rice. The proportion of tiller fertilizer to panicle and grain fertilizer should be 6∶4 or 7∶3.
