花生冬季海南加代繁殖最佳播期研究

Study on Optimum Winter Sowing Date of Peanut about South Reproduction

海南加代繁殖已成为目前花生加快育种进程的一种有效途径,但很多人对南繁花生最佳播期把握不准。针对这一问题,根据南北方气温的差异,本研究设置了6个不同的播期,从南繁花生各个生育期积温需求、植株性状、产量、品质等方面分析了海南省冬季花生种植的特点。得出结论为:从产量结果来看,在11月1日-26日期间播种越早,产量越高,各处理分别比最晚播种日期(11月26日)处理增产114.9%、60.1%、26.6%、27.2%、7.5%。为了规避台风的影响,南繁花生最好在台风过后播种,一般年份在11月初。

Seed reproduction in Hainan has become an effective way to accelerate the breeding process of peanut, but many breeders are not sure about the best sowing time. To solve this problem, according to the temperature difference of North and South China, 6 different sowing dates were arranged. According to thermal requirement, plant architecture, yield and quality traits and other aspects, the peanut characteristics through winter planting in Hainan were analyzed. The results showed that： from the yield point of view, the earlier the sowing dates during November 1st - 26th, the higher the yield was harvested. The yield increase ratio were 114.9%, 60.1%, 26.6%, 27.2%, 7.5% than treatment of November 26th, respectively. In order to avoid the influence of the typhoon, the optimum sowing date of the seed reproduction of peanut in Hainan is in early November.
