摘要
在双季稻北缘区选用穗数型和穗粒兼顾型的两类早籼稻品种,采用盘育秧,本田模拟机插,设置20.0、23.3、25.0、26.4和30.0cm等5种行距栽植,比较不同行距条件下的分蘖、成穗,以及产量和结构的变化。结果表明:穗数型品种在23.3cm行距、穗粒兼顾型品种在25.0cm行距下分蘖成穗率,产量构成协调,产量也最高。
Two early indica rice varieties which were spike type and spike-seed type were selected to study the change of tiller, spike formation, yield and structure under different line space which were 20.0cm, 23.3cm, 25.0cm and 30.0cm using seeding nursing and field simulation method. The spike type with line space of 23.3cm and spike-seed type with line space of 25.0cm had the high tiller earing rate, harmonious yield components and high yield.
