Abstract:

In order to discuss the water-saving methods suitable for the paddy fields in cold areas in Northeast China, the water consumption, yield and water use efficiency of rice were studied in a cold paddy field in Northeast China, under shallow water-intermittent irrigation (SIT), moisture –intermittent irrigation (MIT) and continuous flooding irrigation conditions (CSF). SIT and MIT are two kinds of intermittent irrigation systems. The results showed that compared with that under CSF, 13.9% and 20.2% of water was respectively reduced under SIT and MIT by decreasing the water loss through evapotranspiration and soil percolation, and the ANOVA analysis showed that at the 0.05 level, the total water consumption under intermittent irrigation (SIT, MIT) was significantly different with that under CSF. The yield of rice under SIT and MIT was respectively 9.4% and 12.7% higher than that under CSF, and the difference was significant (P<0.05). The research showed that intermittent irrigation (SIT, MIT) achieved to increase yield mainly through significant increasing in effective panicles per plant. The water use efficiency under SIT and MIT was increased 28.6% and 42.9%, respectively, and was significantly different with that under CSF (P<0.05). Water-reducing and yield-increasing under MIT were slightly better than those under SIT, but the differences were not significant.
