摘要 [目的]对比沿江地区主推的2种早籼稻栽培方式，摸索不同品种在大面积条件下2种栽培方式的产量潜力。[方法]选择4个沿江地区主推早籼稻品种，分别采用毯秧窄行机插与盘育抛栽2种方式。在田块地力相近的条件下，比较2种栽培方式下的品种表现。[结果]各品种的盘育抛栽方式产量表现普遍优于毯秧窄行机插方式，但毯秧窄行机插全生育期综合效益优势更大。[结论]进一步细化栽培管理措施后，毯秧窄行机插方式可成为沿江地区早籼稻的最佳栽培方式，对多数早籼稻品种均可适用。

Abstract [Objective]To compare two methods for early indica cultivation which promoted along the Yangtze River Region and explore production potential of different varieties under the large area conditions.[Method]Under the condition of near field soil，four main varieties of early indica along the Yangtze river region were chosen to compare the varieties performance by using narrow-row machine transplanting for carpet seedling，tray cultivation and cast-transplanting.[Result]The production performance of varieties by using tray cultivation and cast-transplanting was better than narrow-row machine transplanting for carpet seedling，but it had less advantage in comprehensive benefits.[Conclusion]Narrow-row machine transplanting for carpet seedling could be the best cultivation way of early indica rice along the Yangtze river region after elaborating cultivation management measures， which could be used for most early indica varieties.

近年來，隨着农村劳动力向第二、三产业的转移和国家对农业投入的重视[1]，水稻机械化程度有了很大的提高[2]，水稻机插面积也在不断增加。常规的盘育抛栽较费工费时，与现在农村劳动力大量转移相矛盾，而机插是一项省工省种[3]、节本增效的先进技术，是当下推广的主要栽插方式，也是水稻高效栽培技术的主要发展方向。适宜的机插方式是推广早籼稻机插的一个重要举措，与常规盘育抛栽有着本质的区别。该试验通过对沿江地区4个早籼稻品种在毯秧窄行机插和盘育抛栽方式下的生长及产量等因素进行对比，筛选出适合早籼稻高产高效生产的栽培方式。
