摘要
叶片形状及空间排布是水稻重要的形态特征之一,直接影响水稻的光合作用。为探讨在黑龙江寒地特殊生态环境下,超高产水稻品种的叶部特征,指导寒地超高产水稻品种的选育,开展了本研究。以黑龙江超级稻松粳9号、龙稻5号和龙粳14为试验材料,分别以生产中同熟期的品种藤系138、龙稻3号和合江19作为对照,进行了水稻群体叶面积动态、齐穗期功能叶片的各性状以及与干物质积累的关系等研究,根据试验结果,结合笔者的高产育种经验,提出黑龙江省高产水稻开花后的上3叶特征应为：剑叶较长、基角和张角小,倒2叶和倒3叶厚、基角10°~20°、张角20°~30°,叶片衰老慢。
Shape and arrangement of leaves were one of the most important morphological characteristics which im- pact rice photosynthesis directly. Our study was to explore leave characteristics of super high yield rice varieties in the unique cold ecological environment of Heilongjiang province as well as to instruct super high yield rice breed- ing. Three super rice varieties Songjing 9, Longdao 5, and Longjing 14 were adopted as varieties, and the same growth period varieties Fukei 138, Longdao 3, and Hejiang 19 were used as controls, respectively. The changes of leaf area of rice population, each character of functional accumulation were studied in this experiment. Based on leaves at heading stage and its relationship with dry matter the results of the experiment in combination with author＇s breeding experience, we proposed that characteristics of the upper 3 leaves after heading stage were as follows ：lon- ger flag leaf with small basic angle and drooping angle, thicker upper 3 and 2 leaves with basic angle from 10° to 20° and drooping angle from 20° to 30° ,and slow velocity of leaves senescence.
