2011-2012年在湖南长沙以超级杂交稻Y两优1号、杂交稻汕优63和常规稻黄华占为材料进行大田试验,比较了垄作梯式生态稻作(RT)和垄厢生态稻作(B)对水稻产量和光合生理特性的影响.结果表明:与传统稻作(CK)相比,RT的Y两优1号产量显著提高了28.7%,单位面积有效穗数显著提高16.1%,每穗粒数高6.8%,汕优63和黄华占的RT、B处理产量分别高24.3%和19.7%、12.0%和16.2%.RT的Y两优1号叶面积、抽穗前及抽穗后干物质积累量、总干物质量都高于CK,颖花数/叶面积、实粒数/叶面积、粒重/叶面积分别比CK高8.1%、14.8%和15.8%,光合势比CK高32.2%,而净同化率则比CK低9.3% .

Taking super hybrid rice Y-liangyou 1, and hybrid rice Xianyou 63 and conventional rice Huanghuazhan as test materials, a field experiment was conducted in Changsha City of Hunan Province in 2011 and 2012 to investigate the effects of ridge & terraced ecological rice farming (RT) and bed ecological rice farming (B) on rice grain yield and photosynthetic characteristics. Compared with conventional rice farming (CK) , yield of Y-liangyou 1 in the RT was increased significantly by 28.7%, the effective panicles per unit area and spikelets per panicle were increased by 16.1% and 6.8%, respectively....
