摘　　要：本文从库源关系角度探讨了杂交早稻产量形成的生理,提出群体指数和粒/叶比值是群体调节的重要指标,并认为杂交早稻的栽培对策是插足基本苗,平衡施用分蘖肥、穗肥、穗分化肥和粒肥,以促进群体结构均衡发展,协调库源关系.Yield formation physiology was studied on the basis of sink-source theory.Communi-ty index and spikelet(grain)/leaf ratio are submitted as important factors for regulatingcommunity development,cultivation measure is put out as follows:elementary seedlings aresufficiently planted,method of equilbrating fertilization in tilling.differentiation,bootingand heading stage is taken so as to promote community structure development properlyand coordinate relation between sink and source.
