摘要： 以淮稻9号为材料，研究了不同丛苗数对机插粳稻的分蘖和产量性状的影响。结果表明，机插粳稻的分蘖节位、分蘖发生率、穗粒数、千粒重和产量均随丛苗数增加而减少，分蘖成穗率随丛苗数增加则呈先高后低再增的趋势。

关键词: 机插粳稻, 丛苗数, 产量性状

Abstract: Field experiment was conducted on the effects of different seedling number per hill on tillering and yield of machine-transplanted japonica rice cultivar Huaidao 9. The results showed that the tillering position, tillering occurrence rate, grain number per spike, 1000-grain weight and yield of machine-transplanted japonica rice were decreased with the increase of seedling number per hill The spike rate increased at first, then decreased and then increased with the increase of seedling number per hill.

Key words: machine-transplanted japonica rice, seedling number per hill, yield
