Abstract EN
Nonflooded irrigation is an important water-saving rice cultivation technology, but little is known on its photosynthetic mechanism.
The aims of this work were to investigate photosynthetic characteristics of rice during grain filling stage under three nonflooded irrigation treatments: furrow irrigation with plastic mulching (FIM), furrow irrigation with nonmulching (FIN), and drip irrigation with plastic mulching (DI).
Compared with the conventional flooding (CF) treatment, those grown in the nonflooded irrigation treatments showed lower net photosynthetic rate ( P N ) , lower maximum quantum yield ( F v / F m ) , and lower effective quantum yield of PSII photochemistry ( Φ P S I I ).
And the poor photosynthetic characteristics in the nonflooded irrigation treatments were mainly attributed to the low total nitrogen content (TNC).
Under non-flooded irrigation, the P N , F v / F m , and Φ P S I I significantly decreased with a reduction in the soil water potential, but these parameters were rapidly recovered in the DI and FIM treatments when supplementary irrigation was applied.
Moreover, The DI treatment always had higher photosynthetic productivity than the FIM and FIN treatments.
Grain yield, matter translocation, and dry matter post-anthesis (DMPA) were the highest in the CF treatment, followed by the DI, FIM, and FIN treatments in turn.
In conclusion, increasing nitrogen content in leaf of rice plants could be a key factor to improve photosynthetic capacity in nonflooded irrigation.
