五常市地处黑龙江省第一积温带,是黑龙江省南大门,中国优质水稻之乡,素有张广财领下水稻王国之美誉。“五常大米”享誉中外,其原因之一就是五常市拥有独特的五优稻系列品种,五优稻1号、五优稻4号(审定前名称稻花香2号)就是代表。为了保持品种的原始种性不变,科技人员坚持对五优稻系列品种进行提纯复壮。 Wuchang City is located in Heilongjiang Province, the first accumulated temperate zone, is the southern gate of Heilongjiang Province, China’s high-quality rice town, known under the Zhang Guangzai collar rice kingdom reputation. One of the reasons why Wuliangye is famous both at home and abroad is that Wuliangye owns a unique series of varieties of “Wuyouyou”, such as “Wuliangye 1” and “Wudiaoyu 4” (formerly known as “Dashenxiang 2”). In order to maintain the original species of the same species, science and technology personnel adhere to the five varieties of Youyou Purification and Rejuvenation.
