摘要: 在旱育秧方式下,研究了不同播种量和不同秧龄对秧苗素质的影响。结果表明,秧龄在25 d以内,不同播种量之间的秧苗素质差异不大;秧龄超过25 d,播种量为70 g/盘的处理秧苗素质要好于其他播种量处理。

Abstract: The seedling quality of different seeding rates and different seedling ages were studied under the dry nursery. The results indicated that the seedling quality of different seeding rates had little difference when seedling age was less than 25 days.  When seedling age was more than 25 days, the appropriate seeding rate was 70 g per tray. 

Key words: mechanical transplanting rice, seedling age, seeding rate, seedling quality, dry nursery
