| 摘 要： | 以常规粳稻武运粳24号和杂交稻甬优2640为材料,设置钵苗机插高产示范田,探明不同类型品种群体结构特征及其产量形成特点。研究结果表明,甬优2640秧苗素质较高,拷苗后发根力明显优于武运粳24号;群体后期干物质积累及光合势均明显高于武运粳24号;抗倒力矩为64.1 g/茎,较武运粳24号的51.4 g/茎高24.7%,抗倒能力优势明显;最终实测产量为774.6 kg/667 m2,较武运粳24号高6.4%。

| Abstract: | The population characteristics and yield components of different type of rice varieties, conventional japonica rice Wuyunjing 24 and hybrid rice Yongyou 2640 were studied in the high-yielding demonstration of bowl seedling mechanical-transplanted rice. The results showed that the seedling quality and rooting ability, dry matter accumulation after heading and lodging capacity of Yongyou 2640 were significantly higher than Wuyunjing 24. The yield of Yongyou 2640 was 6.4%higher than that of Wuyunjing 24. |
