CK:conventional rice farming；RT:ridge tillage&terraced ecological rice farming；B:bed ecological rice farming.Data followed by the same letter are not significantly different according to LSD（0.05）.

Rice yield of different rice cultivars（except Huanghuazhan in 2011）in the RT was significantly higher than that of the CK（Table 1）.However，there was no significant difference in the rice yield between B and CK.From yield components of the RT，the effective panicle of Yliangyou 1 was 16.1%（12%~20%）higher than that of the CK（P<0.05），no significant difference was observed in spikelets per panicle between RT and CK.Similar results were found in the filling ratio and 1 000-grain weight.The effective panicle of Huanghuazhan and Shanyou 63in the B was 13.5%（7%~20%）and 10.0%（6%~14%）higher than that of the CK，respectively，there was no significant difference in spikelets per panicle between B and CK.Insignificant difference was observed in yield components between B and CK.Harvest index was not significantly different among different ecological rice farming（except for Shanyou 63 in2012）.
