Abstract:
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 A

3, 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.
