湘北地区温光资源较为缺乏，季节紧张，高产难度大，特别是早稻亩产一直是该地生产上的一大难题。1996年，“国家水稻高效示范工程”临澧基点核心试验示范区通过一系列新技术组装，获取了前所未有的大面积高产。经常德市科委和临洼县科委、农业局、统计局联合验收，最高单产为 In the northern part of the region, there is a lack of temperature and light resources, the season is tense, and high-yielding is difficult. In particular, the early rice yield has always been a major problem in the production. In 1996, the “Pilot National Key Project of Rice Efficient Demonstration Project” had achieved an unprecedented large area and high yield through a series of new technology and assembly of the core trial demonstration zone of Linqu base. Often the Municipal Science and Technology Commission and Linwa County Science and Technology Commission, Bureau of Agriculture, Bureau of Statistics joint inspection, the highest yield
