Harvesting and processing of tripterygium wilfordii: After the cultivated tripterygium wilfordii reaches a certain specification, the whole root can be dug in autumn, and impurities such as soil attached to the root can be shaken off after digging, and the outermost root bark can be removed, and cut into sections or thick slices to dry. The remaining stems and leaves after root cutting are also used as medicine and can be dried separately for commodity circulation. Besides harvesting roots in autumn, leaves can be harvested once a year from July to August. 400 ~ 500 kg of roots, 800 ~ 1000 kg of stems and 200 ~ 300 kg of leaves can be harvested every 667 m2, with a total output value of 8000 ~ 15000 yuan.
