| 摘 要： | 土壤缺硒和人体缺硒是当前面临的一个重大问题,探讨施硒浓度、时期和方式对不同谷子品种产量和籽粒硒含量的影响有重要意义。试验采用大田正交设计,以晋谷28号和晋谷21号为供试品种,分别于拔节期和抽穗期进行土壤施硒和叶面喷施不同浓度（0.00、5.48、10.96、21.92、43.84、65.76、98.64、147.96g/hm2）的亚硒酸钠,研究各因素对不同品种谷子产量和籽粒硒含量的影响。结果表明,谷子产量随施硒浓度的升高呈先增加后降低的趋势,施硒浓度为65.76g/hm2时产量最高。籽粒硒含量与施硒浓度呈正相关,随施硒量的增加而增加。谷子产量和籽粒硒含量与谷子品种、施硒时期及方式有关,回归分析结果显示,在抽穗期对晋谷21号叶面喷施浓度为25.41g/hm2的亚硒酸钠是最安全有效的谷子硒强化方案。

| Abstract: | Selenium deficiency in soil and human body is a major problem at present. It is a great significance to study the effects of selenium application concentration, stage and method on yield and grain selenium content of different millet varieties. The field orthogonal design experiment was adopted and ‘Jingu 28’ and ‘Jingu 21’ were used as the tested varieties. Different concentrations of sodium selenite (0.00, 5.48, 10.96, 21.92, 43.84, 65.76, 98.64, 147.96g/ha) were applied to the soil and leaves at the jointing and heading stage to study the effects of various factors on the yield and grain selenium contents of different millet varieties. The results showed that the yield of millet increased first and then decreased with the increase of selenium concentration, and the yield was the highest when the selenium concentration was 65.76g/ha. Selenium content in grain was positively correlated with selenium application concentration and increased with the increase of selenium application. The yield and selenium content of grains were related to millet variety, selenium application stage and selenium application method. Spraying sodium selenite with a concentration of 25.41g/ha on the leaf surface of ‘Jingu 21’ at the heading stage was the most effective selenium enhancement scheme for millet. |
