Abstract
Hybrid rice Y Liangyou 1 was used to investigate the photosynthetic characteristics of canopy,yield components and translocation characters of reserves in stem and leaf sheath by spraying liquid silicon-potash fertilizer equally( 3 000 ml/hm2) at growth stages of 3rd and 4th leaves from the top,respectively. The results showed that spraying liquid silicon-potash fertilizer could increase the stem tillers earing rate,chlorophyll content in flag leaves during grain filling stage,photosynthetic rate,intercellular CO2 concentration and stomatal conductance of rice,while reduce the transpiration rate of flag leaf at filling period. In addition,spraying liquid silicon-potash fertilizer could maintain the high-performance leaf area index( LAI) in top three leaves,improve the canopy architecture,and increase the light utilization efficiency and dry matter accumulation and allocation of rice. Among the three treatments,spraying fertilizer at stage of 3rd leaves from the top was more favorable for canopy architecture and sunlight distribution in plant colonies,and as a result the seed setting rate,filled grain number per panicle and 1 000-grain weight,panicle number,and actual output were much higher.
