对10个小麦品种(系)施用不同硒源,探讨对第二季小麦农艺性状和子粒含硒量的后效应。结果表明,不同硒源后效应对供试小麦的生育期、株高、穗长、粒重没有显著影响,对小麦子粒的含硒量有一定影响;富硒复混肥、富硒矿粉的后效应高于亚硒酸钠,高含量的富硒复混肥和硒矿粉优于低含量的富硒复混肥;品种间的子粒含硒量差异极显著,其含量依次为鄂麦15、鄂恩6号、襄麦20、“2002-163”、“2001-1257”、鄂恩5号、“35888”、“25951”、鄂麦18、鄂麦23。
Different selenium sources were applied to 10 wheat cultivars (lines) to investigate the post-effects on agronomic traits and grain selenium content of wheat in the second season. The results showed that the effect of different selenium sources had no significant effect on the growth seasons, plant height, spike length and grain weight of tested wheat, but had some effect on the selenium content of wheat grain. The selenium-enriched compound fertilizer, After the effect is higher than sodium selenite, high content of selenium-rich compound fertilizer and selenium powder is better than the low content of selenium-rich compound fertilizer; grain selenium content between the very significant difference, followed by the content of Emai 15 E’en 6, Xiangmai 20, 2002-163, 2001-1257, Eren 5, 35888, 25951, Emei 18, Emei 23 .
