中芝8号(74103)是中国农科院油料所用中芝7号与永兴芝麻杂交选育成的单秆型新品种。1980年以来,我所试验结果表明,中芝8号产量高,品质好,比中芝7号增产12～18%。(一)适时早播播种过晚,前期气温高,始蒴部位高,节间长,后期气温下降迫使芝麻提前封顶,上部花不结实,中部籽粒不饱满,产量较低。与6月20日和29日这两个播期比较,6月10日播种
Zhongzhi 8 (74103) is a new single-stalk-type variety bred by Zhongzhi No.7 and Yongxing Sesame, which is used by Chinese Academy of Agricultural Sciences. Since 1980, the results of our experiments show that Zhongzhi No.8 yields high quality and good quality, yielding 12-18% more yield than Zhongzhi 7. (A) timely sowing sowing too late, high pre-temperature, beginning bolt parts of high, internode, the temperature drop later forced sesame capped in advance, the upper flower is not strong, the central grain is not full, the yield is low. Compared with the two sowing dates of June 20 and 29, they were planted on June 10
