摘　　要：在江淮一季稻区,选择穗数型、穗粒兼顾型和超大穗型3种类型杂交中籼水稻品种,采用机插盘育秧,本田模拟机插,设置25.0、30.0和33.0 cm 3种行距,配置15.0 cm株距、每穴2粒种子苗栽培情况下,比较3种类型水稻品种的分蘖与成穗、产量及构成的变化。结果表明:不同类型品种对栽插行距的适应性不同,穗数型、穗粒兼顾型和超大穗型品种机插适宜行距分别为25.0、30.0和33.0 cm。Three line spaces of 25.0 cm, 30.0 cm and 33.3 em were setded in this experiment with row spaces of 15 cm and two seeds per row using fiat-plate seeding and simulating mechanical transplanting in the single-season rice area of middle and lower reaches of the Yangtze. Three types of hybrid indica rice varieties of multi-panicle type, compatible panicle-kernel type and super large panicle type were selected to compare the changes of tiller and Spike formation, yield and its components. The results showed that different types of rice varieties had the different adaptability of transplanting space and the suitable line spaces were 25.0 cm of multi-panicle type, 30 cm of compatible panicle-kernel type and 33.3 cm of super large panicle type respectively with mechanical transplanting.
