高产水稻株系的抽穗前物质生产量、抽穗后物质生产量、生物产量以及经济系数均较高且变异系数相对较小。
Biomass production in the entire growth period, dry matter accumulated before and after heading stage, economic coefficient in high-yield rice were higher and their deviations were relatively narrow.
因此，直立穗型水稻群体物质生产能力较强，生物产量较高，这是其最终经济产量较高的物质基础。
So the erect panicle type population has a bigger dry material production capacity and higher biological yield, these are the physical basis of high economic yield.
光合物质生产子模型中借鉴了水稻的研究成果；
The photosynthesis biomass production submodel was used from reference of rice.
水稻在拔节孕穗后期干物质生产速率最大。
In the late of jointing and booting stage rice has highest dry matter productivity.
