1998年早季在广州的自然生态条件下观察研究了粤杂122的某些形态生理特性,结果认为这个两系法杂交稻新组合属早稻早熟,从插种到始穗历期为83d,在偏酸偏瘦的砂质粘壤土上按常规方法栽培时产量仍可达6723kg hm-2且米质为一级。粤杂122生育前期表现出较强的生长优势,其叶鞘/叶片长度比值小,LAI和干物质增长快,有效分蘖数量多,收获指数达到0.578。但是出穗至乳熟期剑叶及以下二片功能叶的开张角度偏大。
The morphological and physiological characteristics of Yueza 122 were observed under natural ecological conditions in Guangzhou in early 1998. The results showed that the new combination of two-line hybrid rice was premature, with a duration of 83d, Slightly acidic lean sandy loam soil production by conventional methods when the cultivation can still reach 6723kg hm-2 and the quality of a grade. The early growth stage of Yuza 122 showed a strong growth advantage with a small ratio of leaf sheath / leaf length, rapid LAI and dry matter growth, more effective tillers and a harvest index of 0.578. However, the spike to milky ripening leaves and the following two functional leaves opening angle is too large.
