摘要
通过研究水稻主茎叶片生长与温度的关系发现,寒地超级稻松粳9号水稻主茎叶片不同叶位的出叶速度不同,基本上表现为前期快后期慢,主茎叶片的生长与温度关系紧密,除剑叶出叶积温有所下降外,主茎叶片出叶所需积温与叶位呈显著正相关(y=19.1036x-60.0214,r=0.8240*)。
The experiment was conducted with Songjing No. 9, the super rice in Heilongiiang province,on relationship between f leaves-appearance and temperature. The results showed that the leaves grown slowly in prophase and faster in anaphase. There was a close relationship between the leaf appearance and temperature,besides flag leaf, the accumulated temperature had a positive correlation with leaf-position （y=19. 1036x-60. 0214, r = 0. 8240^＊ ）.
