Effects of Dwarfing on Leaf Yield, Leaf contents and Soil Nutrients of Cinnamomum longepaniculatum

The leaf yield, leaf contents and soil nutrients of Cinnamomum longepaniculatum dwarfing experimental forest were determined. The results showed that different dwarfing intensities could significantly affect the leaf yield per unit area (P<0.05), but could not significantly affected the leaf oil content and eudesmol content. In the dwarfing cultivation of Cinnamomum longepaniculatum, the trunk height should be kept at 5—8 m, the stand density should be kept at 1290−1425 plants per hectare, and the leaf yield per unit area should be at a high level. The contents of available potassium, total phosphorus and total potassium in the soil were significantly affected by dwarfing cultivation of Cinnamomum longepaniculatum,. During dwarfing cultivation of Cinnamomum longepaniculatum, potassium fertilizer should be added timely and appropriately to ensure the balance of soil nutrients.
