不同微量元素和土壤酸碱性对油樟叶1,8-桉叶油素含量的影响

Effects of Different Trace Elements and Soil pH on the Content of 1,8-cineole in Cinnamomum longepaniculatum Leaves

微量元素在植物生长中具有重要作用,开展油樟(Cinnamomum longepaniculatum)施微量元素的研究,对油樟的定向培育具有重要意义。试验结果表明,各微量元素和土壤酸碱性对油樟叶中1,8-桉叶油素含量影响的主次顺序不同;硫酸锰、硫酸锌对油樟叶中1,8-桉叶油素含量的影响显著,硫酸亚铁、亚硒酸钠和pH值对油樟叶中1,8-桉叶油素含量的影响均不显著。综合考虑各处理对油樟叶中1,8-桉叶油素的影响情况,最佳的处理是A1B4C2D3E3,即喷施0.5%硫酸锰,0.1%硫酸锌,0.3%亚硒酸钠,pH值为5.5,不施硫酸亚铁时的油樟叶中1,8-桉叶油素含量最高。

Trace elements play an important role in plant growth,and it is of great significance to study the application of trace elements to Cinnamomum longepaniculatum for the directional cultivation of C.longepaniculatum.The results showed that different trace elements and soil pH had different effects on the content of 1,8-cineole in C.longepaniculatum leaves.Manganese sulfate and zinc sulfate had significant effects on the content of 1,8-cineole in C.longepaniculatum leaves,while ferrous sulfate,sodium selenite and pH had no significant effects on the content of 1,8-cineole in C.longepaniculatum leaves.Considering the effects of all treatments on 1,8-cineole in C.longepaniculatum leaves,the best treatment was A1B4C2D3E3,namely 0.5%manganese sulfate,0.1%zinc sulfate,0.3%sodium selenite,pH value was 5.5,and the content of 1,8-cineole in C.longepaniculatum leaves was the highest without ferrous sulfate.
