摘要
在分析我国水稻产量提高和株型变迁时代特征的基础上,通过对众多水稻株型模式差异的比较,阐述了超级杂交稻“高冠层、矮穗层、中大穗”株型模式的特点。从理论上,初步分析了该模式“有效增源、扩建高库容、高源库水平的协调”、“矮穗层”的抗倒力学及生理学等方面的理论基础。同时,通过对超级稻超高产实例的分析,率先提出了超级稻实现超高产目标的部分生理指标,重点介绍了适于超级杂交稻超高产栽培的改良型强化栽培技术体系。
This article dealt with the relationship between rice yield increase and plant type improvement during last 50 years in China. The characteristics of the plant type of super hybrid rice were analyzed, compared with few advanced rice plant type in this review. The effective LAI increase, high sink capacity, the balance for high-level source ＆ sink, physical and physiological basis of the lodging-resistance was discussed in the view of high yielding theory of super hybrid rice. Also, super high-yielding examples and relative techniques were introduced for the super hybrid practice.
