摘 要: 反映根冠定性关系的主要观点有 ,形态平衡论、环境决定论和功能均衡论 .描述根冠定量关系的模型有四种 ,即异速生长模型、Thornley模型、功能均衡模型和激素模型 .功能均衡理论已在农业节水研究中得到广泛应用 . The main viewpoints on the root shoot qualitative relations are morphological equilibrium, determining by environment and functional equilibrium. Four kinds of models about root shoot quantitative relations are allometric model, Thornleys model, functional balance model and hormone model. The functional balance model has been widely applied to agricultural water saving research.
