Abstract
- Objective: To study the effects of different plant density and harvest time on the yield and quality of Miao medicine Blumea balsamifera, in order to provide a theoretical basis for Good Agriculture Practice( GAP).<br />Methods: Two factors trails were used to research the influence of plant density and harvest time on the yield and quality of Blumea balsamifera. The plant density were located at 50 cm × 90 cm,50 cm × 60 cm,50 cm × 30 cm and 30 cm × 30 cm, and the harvest time were set up at mid-October, mid-November and mid-December. The experiments were designed with randomized block design.<br />Results: Yield and quality were both affected by the plant density and harvest time. Yield per unit area and volatile oil yield per unit area were increased significantly with the increasing of plant density. Yield per unit area and volatile oil yield per unit area were peaked at the plant density of 111 112 plants / hm~2 which could obtain high-yield at the mid-December, which were 1 546. 68 kg / hm~2 and 96. 6 L / hm~2,respectively. The content of total flavonoids were peaked at the plant density of 22 223 plants / hm~2 and 111 112 plants / hm~2,which were 2. 50 and 2. 53 mg/g,respectively. Harvest time had no significant effect on the flavonoids content.<br />Conclusion: The suitable plant density of transplanted root tillers of Blumea balsamifera is 111 112 plants / hm~2 and the optimum harvest time is December.
