| Abstract: | Relationship between dry matter production and light interception by canopy was analyzed based on the data of canopy structure and rice dry matter measured in different growth stages of rice experimental field under plastic film mulched upland (RPFMU) and water saving irrigation condition. Two formulas are proposed that comparatively reasonable to describe the regulation of dry matter growth of RPFMU. |

| Keywords: | rice plastic film mulched upland dry matter production light interception model |
