摘　　要：八红优256是2004年审定通过的第一代高大韧水稻品种。为了充分发挥该品种的优良种性,于2012年对该品种进行了大面积的栽培技术示范,重点开展该品种在桂中地区的辐射推广工作。在桂中和桂南地区,各设立两个品种栽培技术示范点,早晚稻各示范面积23.33 km2。在桂中的9个县区强化开展新品种的辐射推广工作。比较和分析八红优256桂中和桂南在早稻和晚稻的示范与推广中稻谷产量的差异。试验结果揭示,八红优256在桂中南地区一般产量7800—8400kg/hm2,作早稻和作晚稻栽培产量差异不显著,在桂中和在桂南地区栽培产量差异也不显著。说明八红优256是桂中和桂南地区典型的早晚兼用型品种,具有较广环境适应性,采取科学的栽培技术方法可以获得高产或超高产。研究结果重新验证了八红优是广适性、早晚稻兼用型、易栽培的高产优质高大韧稻品种。Bahongyou 256 is one of the first batch of ＂ tall plant-big panicle and tough stalk rice＂ varieties which passed the variety evaluation in 2004.In order to apply its superior varietal characteristics in production,the variety was demonstrated in cultivation technique and a large scale in 2012,focus on further extension in Central Guangxi region.Four cultivation technique demonstration blocks were established in central Guangxi and southern Guangxi regions and the demonstration area in early and late rice was 23.33 km2,respectively.The extension of the new variety was strongly carried out in 9 counties or districts of the central Guangxi region.The difference of grain yield per mu was compared and analyzed between central and southern Guangxi regions and between early and late rice.Experimental results proclaimed that the grain yield of the variety Bahongyou 256 was generally 7800-8400kg / ha.and there was not significantly different between early and late rice and between central and southern Guangxi regions as well.The results showed that the Bahongyou was an early and late dual-use type rice suitable for the central and southern regions of Guangxi Province and could achieve high yield or super-high yield by applying reasonable cultivation technique.These study results re-confirms that the variety Bahongyou 256 is a kind of high yield and top quality ＂ tall plant-big panicle and tough stalk rice＂ variety possessing advantage characteristics such as wide adaptation to various environments,dual-use as early and late rice varieties and easy cultivation.
