| 摘 要： | 对超级稻Ⅱ优航2号进行不同叶龄和插植密度试验。结果表明,3.5叶龄用26.4cm×26.4cm的密植,5.0叶龄用17.8cm×17.8cm、23.1cm×23.1cm和26.4cm×26.4cm均可达到较好的产量水平。在生产上选择5.0叶龄插秧较为适宜;各密植规格之间差异不显著,应依据栽培条件、品种特性水平而适当选择其中一种密植规格。

| Abstract: | Different leaf ages and planting densities of super rice Ⅱ You Hang No.2 were studied. The results showedthat higher yield levels could all be achieved at a hill spacing of 26.4cm × 26.4cm with 3.5-leaf-old seedling, or a hillspacing of 17.8cm × 17.8cm, 23.1cm × 23.1cm,26.4cm × 26.4cm with 5-leaf-old seedling. The more suitabe transplanting leaf age on rice production was 5-leaf-old seedling. There were no differences in grain yield among various planting densities. We should select one of the planting densities according to cultivation conditions and varietal charcteristics. |
