Embodiment 1

[0015] The Artemisia annua stalks harvested in the same year were collected together, the side branches were removed uniformly, the main trunk was soaked in adhesive and dried, stacked vertically, reorganized and integrated, put into a mold for high temperature and high pressure shaping (hot pressing temperature was 150°C, hot pressing pressure was 5MPa , the hot-pressing time is 2 minutes per millimeter thick integrated bonded Artemisia annua stalks), after cooling and solidifying, cut into boards, that is, boards with health care functions. The board retains the color and texture of the Artemisia annua stalks and the volatile components contained in the Artemisia annua stalks, and the contained volatile components have the functions of inhibiting bacteria, preventing mosquitoes, clearing away heat and detoxifying. The plate with health care function prepared in this embodiment can be used to make floors, furniture and building materials.

Abstract

Disclosed is a comprehensive utilization method of Herba Artemisiae Annuae straw and the use thereof, wherein the method comprises the following steps: manufacturing a plate having healthy functions, using the stalks of Herba Artemisiae Annuae straw; manufacturing bio-charcoal using the side stalks of Herba Artemisiae Annuae straw and the residue thereof. The invention also relates to the use of Herba Artemisiae Annuae straw in the preparation of plates having healthy functions and bio-charcoal. The method makes the best use of Herba Artemisiae Annuae straw. The plates made by the stalks thereof have natural textures and colour, and are light and hard-wearing; and the volatile components in the plants of Herba Artemisiae Annuae are retained and the plates are anti-microbial, anti-mosquito and heat-clearing and detoxifying in use; the bio-charcoal made by the side branches and the residue thereof can increase organic content and the carbon acquisition cabability of the soil.

Description

technical field [0001] The invention relates to the field of environmental protection and recycling, in particular to a comprehensive utilization method of Artemisia annua straw. Background technique [0002] Artemisia annua is a traditional Chinese medicine in my country. It has the effects of clearing away heat and detoxification, soothing the liver and promoting gallbladder. As early as in Ge Hong's "Behind the Elbow", it was recorded that Artemisia annua can be used to treat malaria. In the 1970s, Chinese scientists isolated artemisinin from Artemisia annua. Artemisinin and its derivatives have become the first-line drugs for the treatment of malaria, which is related to the lives and health of hundreds of millions of malaria patients. Due to the complex structure of artemisinin and the high cost of chemical synthesis, the main source is still extracted from the plant Artemisia annua. The annual global demand for artemisinin is between 150 and 200 tons. Correspondingly,...
