摘　　要：通过规格化塑料硬盘不同播种量处理探究机插秧对通禾899空穴率发生情况及产量品质的影响。结果表明,株高随播种量的增加而降低,千粒重与成熟度均随播种量的增加而提高。60 g/盘播量条件下,本田1棵苗及空穴发生概率最大且产量最低,120 g/盘播量条件下本田1棵苗及空穴发生概率最小且产量最高。60~120 g/盘播量下稻米的外观及适口性品质差异不大,而加工品质中整精米率随播量的增加而提高。生产上机插秧建议采用100~120 g/盘播种量。The effect of transplanting seedling on hole rate and yield quality- of Tonghe 899 was investigated by different planting quantity treatment of normalized plastic hard disk. The results showed that the plant height decreased with the increase of seeding amount, and the 1000-grain weight and maturity increased with the increase of seeding amount. Under the condition of 60 g/sowing quantity, the occurrence probability- of 1 Honda seedling and hole is the highest and the yield is the lowest, under the condition of 120 g/sowing volume, the occurrence probability- of 1 Honda seedling and hole was the lowest and the yield was the highest. The appearance and palatability- quality- of rice under 60-120 g/plate seeding quantity did not differ much, while the whole precision rice rate in processing quality increased with the increase of seeding quantity. It is recommended to adopt 100-120 g/plate seeding amount for transplanting rice by machine.
