摘　　要：[目的]探索地力水平较低情况下的水稻高产技术途径。[方法]通过不同栽培途径塑造中籼稻不同群体结构,比较其生长发育以及产量形成的异同。[结果]新两优6号在中低产田区,可以增加密度而适当降低每穴栽插的棵数以获得较高的产量。丰两优4号不适宜多本栽插,以单本单本低密度产量最高。[结论]中低产田区可以采取高密低本的栽插路线以获得较高的水稻产量。[Objectives] this paper aims to explore high rice yield technology route in low fertility level area.[Methods] Cultivated through different ways,similarities and differences of different group structure of rice route and its growth state and output are compared.[Results] New ＂Liangyou No.6＂could enhance density and lower numbers of plants in each hole so as to get high output in middle and low yield field.＂Fengliangyou No.4＂is not suitable to cultivate and has highest single-seed-low-density-output.[Conclusions] Low and middle yield field could enhance rice output by adopting the high-density-low-cost cultivation way.
