2013年9月28日,农业部组织国内著名水稻研究专家,对地处湖南省隆回县羊古坳乡牛形村的第四期超级杂交稻苗头组合“Y两优900”6.75 hm2(101.2亩)高产攻关片进行了现场测产验收。以谢华安院士任组长的验收专家组,在考察百亩攻关现场的基础上,对示范单位推荐的1个田块、抽签确定的2个田块进行了测产,经烘干除杂后,按标准含水量13.5%折算,分别折合亩产1045.9 kg、937.6 kg、980.7 kg,按算术平均百亩片平均亩产988.1 kg,创造了全国水稻百亩连片高产记录。“Y两优900”是在袁隆平院士提出的新型高秆超级杂交稻研究技术路线指导下,由袁隆平院士创
On September 28, 2013, the Ministry of Agriculture organized a well-known domestic rice research expert to study the combination of the fourth super hybrid rice “Y Liangyou 900” 6.75 hm2, located in Niugeng Village, Yangguo Old Township, Longhui County, Hunan Province (101.2 acres) high-yielding offensive film site survey and acceptance. On the basis of examining the site of a mu of land, the inspection and acceptance expert group under the chairmanship of Xie Huaan was tested on 1 plots recommended by the model unit and 2 plots determined by lottery. After drying and impurity removal , According to the standard 13.5% water content conversion, respectively, equivalent to 1045.9 kg per mu, 937.6 kg, 980.7 kg, according to the arithmetic average mu mu average yield of 988.1 kg, creating a national high yield of rice contiguous record. “Y Liangyou 900 ” is under the guidance of the new high-stem super hybrid rice research technique proposed by Academician Yuan Longping, initiated by Academician Yuan Longping
