摘　　要：简述了水稻壮秧的形态特征和合理稀植的概念,分析了壮秧所具有的优良生理素质与合理稀植所具有的生理优势,对壮秧稀植高产的生理实质进行了探讨。指出水稻高产栽培的生理实质是在产量形成期建立高光效群体,这与目前世界高产稻作的发展趋势相一致。In the paper, the authors report the concept of proper thin planting of rice and the morphological characters of strong seedlings at first. On this basis, the good physiological quality of rice strong seedling and the physiological dominance of proper thin planting analyse. The physiological superiority of TPHYC is also discussed. It is accentuated that the physiological superiority of high yielding cultivation is the product of the colony of high photosynthesis efficiency at the yielding stage. It is associated with the revolution tendency of high yielding of rice in the world.
