外源硒肥对澳洲坚果硒含量及产量的影响

Effects of Exogenous Selenium on Selenium Content and Yield of Macadamia

通过田间试验,研究喷施不同浓度的外源硒肥对澳洲坚果果仁硒含量以及产量的影响。结果表明,叶面喷施适宜的种植用有机硒素可提高澳洲坚果果仁中硒含量和产量,硒含量随施硒浓度减少而降低,产量随施硒浓度的减少呈先升高后降低的趋势。

Field experiments were carried out to study the effects of different concentration exogenous selenium on selenium content and yield of macadamia.The results showed that spraying suitable organic selenium for planting on leaves could increase the selenium content and yield of macadamia. The content of selenium decreased with the decrease of selenium concentration, and the yield increased first and then decreased with the decrease of selenium concentration.
