水稻叶龄动态的模拟及应用

Imitation and Application of Tendencies of Rice Leaf Age

摘要:

对4个水稻品种插秧至抽穗期的出叶动态进行了模拟, 结果表明, 各品种模拟值与实际观察值吻合较好。根据叶龄与根、蘖、穗等器官的同伸关系, 用叶龄模型预测各器官的发育进程, 可用以编制水稻生长日历, 同时提供相应的促、控措施, 使水稻品种的高产潜力得到充分发挥。

Abstract:

This article imitated leaf tendencies to four rice varieties from period of plantation to ear extension. The result showed that the imitated value better anastomosed actual observed value. Leaf age model can be used to predict organ-growth prlcessaccording to synchronoius relation of root, off shoot and ear with leaf ageand rice growth calender can be made with proper promoted and controlled steps to make high yield protiality of rice varieies exert.
