| Abstract: |
| During the later growth stage，the net photosynthetic rate and transpiration rate of plastic film mulching cultivation were the highest in different cultivation patterns，in particular，net photosynthetic rate of plastic film mulching cultivation were higher by 11.84%，19.92% and 14.90% than nude field dry cultivation，plastic film mulching waterland cultivation and conventional cultivation，and its transpiration rate was higher by 12.1%-25.1% than others，and as the growth stages promoting，the differences increased. On the other hand，compared with CK，mulching cultivation enhanced luorescence dynamics parameter-Fv/Fm and Yield，it was beneficial to potential activity of PSII and actual capture rate of luminous energy. Among the treatments of mulching film，for straw and liquid film，mulching film was the best one. Otherwise，different water management had little effect on fluorescence dynamic parameters of super hybrid rice. |
