摘要
不同芝麻品种的施硼试验结果表明,白芝麻品种中芝8号增产9.6％—21.2％,黄芝麻品种金芝麻增产3.3％—19.9％,黑芝麻品种青麻增产2.1％—17.1％。中芝8号对缺硼反应敏感,症状明显,金芝麻和青麻次之。硼在不同芝麻品种各器官的含量由高到低顺序是花、叶、叶柄、茎、根。各器官硼浓度随着施硼量的增加而提高,但吸硼过量抑制生长甚至中毒致死。
Experimental results showed that the yield of sesamewas significantly improved when boron was applied.The White Zhongzhi No.8 obtained a yield increase of 15.0%, and the Golden Turkey of 10.2% and the Black Qingma increased by 6.7%. The symptoms of boron-deficiency in various sesame varieties were different, Among which, Zhongzhi No.8 was most sensitive to B-deficiency followed by Golden Turkey and Qingma.The sequence of boron contents in different portions of plant was as flower>leaves>stem>root. The total content of boron in seeame plant was positively related to the amount of boron applied, but over-application of boroon was harmful.
