水稻叶片出生期与器官伸长各期的对应关系

CORRESPONDING RELATIONS BETWEEN LEAFING STAGE OF RICE AND ELONGATION STAGE OF RICE ORGANS

研究通过稻株的解剖、观测，得出了叶片出生期与相应器官（叶片、叶鞘及节间）伸长各期（始期、最盛期及终期）的对应关系。运用此种关系，根据水稻叶龄进程，较准确地推知相应器官生长动态。并为调整水稻群体生态。

Through dissection and observation of rice plant, the corresponding relations between leafing stages of rice leaves in different positions and elongation periods, such as early stage of elongation, prevailing elongation and terminal elongation, of relevant rice organs including leaf, leaf sheath and internode were reached. Knowing these relations, Acorrding to rice leaf age, we can calculate and know the growth tendecies of the relevant rice organs more correctly. And also offer the theory basis to adjust rice group ecological system.
