在毛主席革命教育路线的指引下,今年晚季,我们同院教学农场、工人综合教研组老师一起开展了“三结合”的杂交水稻制种试验;其中“闽优一号”制种1.85亩,父母本行比为2:4的0.85亩获得亩产杂交一代种子228斤的高产量。现将主要的技术要点小结于下:一、花期准相遇:父母本花期是否相遇是制种成败的关键;而把花期巧安排在一年中最适的天气里相遇是制种获得高产的一项根本措施。查阅了沙县洋坊地区历年的气象资料和参照今年的气象预报,经分析,我们认为本地区晚季最适水稻抽穗开花的季节在九月上中旬。
Under the guidance of Chairman Mao’s revolutionary education line, this late autumn season, we conducted a hybrid rice seed production experiment with “three combinations” of teaching farm and workers’ comprehensive teaching and research group. Among them, “” 1.85 mu, 0.85 mu of 2: 4 ratio between parents and parents, and 228 kg of high yield per mu of hybrid seed. The main technical points are summarized below: First, the flow of prospective encounter: whether the parents of the flowering is the key to the success of seed production; and the flowering coincidence arranged in the best weather in the year meet is the seed production to obtain a high yield The basic measure. According to the historical meteorological data of Yangfang area in Shaxian County and the weather forecast of this year, we think the season of heading and flowering of the most suitable late-season rice in this region is mid-September.
