自1928年Mason和Maskell提出作物产量的源库理论(Source-sink theory以来,人们常以源库的观点探索作物高产的途径。在水稻生产上,如何协调源库关系,使水稻产量进一步上升,诸家看法莫衷一是。如凡特逊等认为,叶片是主要的光合生产源,要增加产量,必须提高适宜的叶面积指数(LAI)。田中明、村山登等则认为,产量库容对源的生产有反馈调节作用,要提高产量,必须扩大产量库容,即提高总颖花
Since Source-sink theory was put forward by Mason and Maskell in 1928, people often explore the ways of high-yield crops from the point of view of source-sinks.In rice production, how to coordinate the relationship between source and sink so as to further increase the yield of rice, As the Vetterson believes that the leaves are the main sources of photosynthetic production, to increase production, we must increase the appropriate leaf area index (LAI) .Tian Zhongming, Murayamang Deng believes that the production capacity of the source of production Feedback regulation, to increase production, we must expand production capacity, that is, to increase the total spike
