摘　　要：为探索优质稻泰丰优79适宜的育秧方式,本研究设置旱育秧、湿润育秧、钵盘育秧3个处理,对比3种育秧方式对其农艺性状及产量构成因素的影响。结果表明,钵盘育秧产量最高,单产为667.8 kg/667 m^(2),比湿润育秧增产5.9%,比旱育秧增产2.9%。对不同育秧方式下水稻茎蘖动态、农艺性状及产量构成因素分析表明,钵盘育秧水稻有成穗率高、结实率高、有效穗多的特点。在生产上,水稻育秧建议以钵盘育秧为宜。In order to explore the appropriate seedling rearing methods for high-quality rice Taifeng You79,three treatments were set up:dry seedling rearing,wet seedling rearing and alms bowl seedling rearing,and the effects of these three seedling rearing methods on its agronomic traits and yield components were compared.The results showed that the highest yield was 667.8 kg/667 m^(2),which was 5.9%higher than that of wet and 2.9%higher than that of dry.Analysis of tiller dynamics,agronomic traits and yield components of rice under different seedling rearing methods showed that al bowl cultivated rice had high heading rate,high setting rate and many effective ears.In terms of production,it is suggested that rice seedling should be cultivated in alms bowl.
