叶片光合速率易受温光条件的影响。杂交晚稻插秧时间几天之差可使产量相差很大。其原因之一是早插的光合速率高,干物质积累多,能为形成大穗提供物质基础。杂交晚稻灌浆过程与常规稻不同
Leaf photosynthetic rate is susceptible to temperature and light conditions. The difference between days of hybrid rice transplanting a few days can yield a great difference. One of the reasons is that the early photosynthesis rate is high, and the accumulation of dry matter is more, which can provide the material basis for the formation of large ears. Hybrid late rice filling process is different from conventional rice
