Abstract
The application discloses a method for improving the quantity of Michelia maclellandii oil, which comprises the following steps: (1) covering the top of Michelia maclellandii seedling with a shading net, wherein the light transmittance of the shading net is 75-85% during March to July, the light transmittance of the shading net is 35-45% during August to October, and the shading net is subjected to full natural light during November to next February; meanwhile, fertilizers are sprayed every 25-35 days during April to September; (2) picking fresh leaves of Michelia maclellandii in the second year, and extracting oil. Through strictly adjusting the light conditions in different months, the fertilizing mode during the growth of Michelia maclellandii, and cooperating with the timing of branch and leaf pruning, fresh leaf picking and oil extraction, the fresh leaf weight and the oil yield of fresh leaves of the Michelia maclellandii seedling are greatly improved, so that the total oil yield of the Michelia maclellandii oil is greatly improved.
