近年来,我省红麻生产发展较快,但由于夏季日照过长,秋季降温早,使由南方引种的晚熟性红麻品种不能收到成熟的种子,每年需从两广地区调种,影响红麻生产的发展。红麻为短日性植物,在生育期中需要有每天10～12小时并连续30～40天的短日照和高温气候,才能开花结籽。据此,我们于1976年进行了红麻短光照制种试验,并取得一些初步结果。1977年围绕提高种子产量、简化制种技术、降低生产成本等问题继续进行试验,同时使用76年的制种 In recent years, the development of kenaf in our province has been developing rapidly. However, due to the long sunshine in summer and the early fall in autumn, the late-maturing kenaf varieties introduced from the south can not receive the mature seeds. Therefore, Ma production development. Kenaf for the short-day plants, in the growing season need to have 10 to 12 hours per day for 30 to 40 days of short sunshine and hot weather in order to flowering and seed. Accordingly, we conducted a kenaf short-wave test in 1976 and achieved some preliminary results. In 1977, it continued to test the issues of raising seed yield, simplifying seed production techniques and reducing production costs, and used 76-year seed production
