摘要: 硒元素是人体必需的微量元素之一,具有重要的保健作用。采用不同施肥方式及不同施肥浓度,研究纳米硒肥对旱优73号水稻硒含量和产量的影响。结果表明,667 m2根施150 mL纳米硒肥可有效提升水稻各器官硒含量,其中叶片硒含量变化最为显著。水稻籽粒中,硒含量顺序为T2>T1>T3>T4,即T2处理效果最佳,当过量施用纳米硒肥时水稻对硒元素的吸收会被抑制;T2处理对水稻可有效促产,相较CK增产17.49%;水稻种植一年后,T2处理的土壤中硒含量小幅降低,其余处理土壤中硒含量均不同程度升高。本文通过比较不同纳米硒肥施肥方式及不同浓度下水稻对硒的吸收能力,增产增效生产出了优质的富硒大米。

Abstract:

Selenium is one of the essential trace elements for the human body and has important health benefits. Different fertilization methods and concentrations were used to study the effects of nano-selenium fertilizer on selenium content and yield of rice variety Hanyou 73. The results showed that 150 mL of nano-selenium fertilizer applied to 667 m2 roots could effectively increase the selenium content of rice tissues, and the selenium content in leaves changed most significantly. In rice grains, the selenium content was in the order of T2>T1>T3>T4, that was, T2 treatment had the best effect, and the absorption of selenium in rice would be inhibited with excessive application of nano-selenium fertilizer. T2 treatment could effectively promote the yield of rice, which was 17.49% higher than that of CK. One year after rice planting, the selenium content in the soil treated with T2 decreased slightly, and the selenium content in the other treated soils increased to varying degrees. In this paper, we compared the selenium absorption capacity of rice under different nano-selenium fertilizer fertilization methods and concentrations, and increased yield and efficiency to produce high-quality selenium-rich rice.
