通过人工插秧精确模拟机插秧不同穴苗数，研究不同取秧量对亚种间杂交粳稻新品种‘浦优22’产量的影响。结果表明：穴苗数为2～3株时，‘浦优22’的有效穗和每穗总粒数协同提高，总颖花量达到了7．5×108/hm2以上，在结实率和千粒重正常的情况下，‘浦优22’能够稳定实现12．0 t/hm2的高产水平。

‘Puyou 22’,a new japonica hybrid rice cultivar gained by japonica-indica hybrid between subspecies,its yield with different planting seedlings per hill was studied in the way of manual planter to actually simulate the transplanter.The results showed that ‘Puyou 22’could get a good combination of productive panicle number and total grain number per panicle with 2-3 planting seedlings per hill, which could help to get a excellent total spikelets over 7.5 ×108/hm2 that met the need of getting a steady high yield of 12.0 t/hm2 .
