Problems solved by technology

However, the traditional storage method of Artemisia annua seeds is to dry the harvested Artemisia annua seeds and store them in a dry and ventilated environment at room temperature. Using this storage method, insect bites and mildew of Artemisia annua seeds are more serious, resulting in The germination rate is extremely low, usually only about 30%

Abstract

The invention relates to the field of seed storage, in particular to a composition and application thereof in artemisia carvifolia seed storage. The invention provides a composition comprises asclepias curassavica, hemlock, Indian tobacco, caladium and trachelospermum jasminoides, extract and application thereof and further provides an artemisia carvifolia seed storage agent and method. Experiments show that the problems of insect biting and mildewing in the storage process of artemisia carvifolia seeds can be effectively solved by adopting the artemisia carvifolia seed storage agent, and germination rate of the artemisia carvifolia seeds can be increased greatly by 37-57% when compared with that of conventional storage methods.

Description

Technical field [0001] The invention relates to the field of seed storage, in particular to a composition and its application in the storage of A. annua seeds. Background technique [0002] Artemisiae annie L. is a traditional Chinese medicine in my country, belonging to the genus Artemisia in the Compositae family. Artemisinin, one of its extracts, is the most effective clinical medicine for the treatment of malaria. In-depth pharmacological studies have shown that artemisinin and its derivatives are a broad-spectrum natural medicine. According to statistics, more than 1 million people die of malaria every year in the world. The resistance of malaria parasites limits the effectiveness of the antimalarial drug chloroquine, and artemisinin has the characteristics of low toxicity and quick-acting effects on malaria. [0003] At present, artemisinin is recognized as an effective drug of choice for the treatment of malaria, which makes Artemisia annua, the raw material for extracting...
