摘　　要：以H优518和陆两优996为供试材料,研究了不同秧龄处理对机插秧秧苗素质、生育期、分蘖能力及经济性状的影响。结果表明:不同秧龄对机插双季晚稻的秧苗素质、生育期及产量等均有一定影响,在该试验条件下,H优518和陆两优996作双季晚稻机插栽培时,秧龄以17 d为最适宜,产量分别为577.3和541.7 kg/667m2。并在试验的基础上,提出了水稻机插栽培的几点注意事项。Taking Hyou518 and Luliangyou996 as experimental materials, the influences of transplanting at different seedling ages on quality, growth period, tilling ability and economic characters of machine transplanting seedlings were studied. The results showed that transplanting at different seedling ages had a certain influences on quality, growth period, tilling ability and economic characters of machine transplanting seedlings; under the experimental conditions, machine transplanting culture of Hyou518 and Luliangyou996, which were took as double-season late rice, the optimal seedling age was 17 d, and their yield reached 8 659.5 kg/hm2 and 8 125.5 kg/hm2, respectively. Moreover, on the basis of experiment, some notes for machine transplanting culture of rice were put forward.
