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%.
Field experiments were conducted in Changsha, Hunan province from 2011 to 2012 with the hybrid rice Y Liangyou 1, hybrid rice Shanyou 63 and conventional rice Huanghua Zhan as materials, B) on the yield and photosynthetic characteristics of rice.The results showed that the yield of Y Liangyou 1 increased significantly by 28.7% and the effective panicle per unit area increased significantly by 16.1% compared with that of CK The grain yield per hectare was 6.8%, and the yield of RT and B of Shanyou 63 and Huanghuazhan were 24.3% and 19.7%, 12.0% and 16.2% higher than that of Shanyou 63 and Huanghuazhan respectively.The leaf area, dry matter accumulation before heading and after heading CK, leaf number, number of spikelet / leaf area, grain weight / leaf area were 8.1%, 14.8% and 15.8% higher than CK and photosynthetic potential was 32.2% higher than CK. While the net assimilation rate is 9.3% lower than that of CK.
