粳型杂交稻在不同播栽期的生育动态和粒重分布

DEVELOPMENTAL DYNAMIC AND GRAIN-WEIGHT DISTRIBUTION ON DIFFERENT SOWING-PLANTING PERIODS AT JAPONICA HYBRID RICE

本文探讨了粳型杂交稻在不同播栽期的某些生长发育指标的动态,分析了一穗上谷粒粒重的分布并在此基础上提出作为后季晚稻利用的粳型杂交稻亩产千斤的高产途径。

This paper illustrates and discusses the dynamic variance on several growth development index on the different sowing-planting periods at Japonica hybrid rice, further analyses the grain weight distribution on a spike. on this basis, the authors suggest the high—yield pathway of 500kg per Mu at Japonica hybrid rice as later—season rice.
