Problems solved by technology

[0003] Because Artemisia annua is sensitive to nitrogen and potassium, there is currently no special fertilizer for Artemisia annua produced and sold on the market, and the nutrient ratio of other compound fertilizers does not meet the growth and development needs of Artemisia annua, and its nitrogen content is high, while the potassium content low, which is very unfavorable to the synthesis and accumulation of artemisinin in Artemisia annua, and the general organic matter does not meet the requirements of Artemisia annua for the type of organic matter
The amount and type of common fertilizers directly affect the yield of Artemisia annua leaves and the content of artemisinin in Artemisia annua leaves, which is difficult for growers to grasp.
At the same time, in the industrial production process of artemisinin extraction, there is a problem that a large amount of artemisinin residue needs to be disposed of

Abstract

A special fertilizer for sweet wormwood consists of urea 10-20%, phosphamidon 12-25wt%, potassium sulfate 20-30wt%, special organic substance 15-32wt%, special additive 0.5-2.0wt% and zeolite powder 7-18wt%. The special additive comprises of Mg, Mo, B, Zn and Mn. The process is carried out by aging the special organic substance at 40-60DEG C by dilute solution, adding into lump lime, mixing, balancing above 24hrs, regulating pH value to 6-8 and drying. It has more yields.

Description

technical field [0001] The invention relates to a special fertilizer, in particular to a special fertilizer for Artemisia annua. Background technique [0002] Artemisinin is recognized by the World Health Organization as the most effective antimalarial drug. Artemisia annua, especially the leaves of Artemisia annua are the main raw materials for extracting artemisinin. Only when the content of artemisinin in the leaves of Artemisia annua is ≥0.5%, the artemisia annua has industrial processing value, and the content of artemisinin in the leaves of Artemisia annua directly affects the Artemisinin extraction cost and quality. Due to the sharp increase in the international demand for artemisinin, the wild Artemisia annua resources in my country have been severely damaged. Therefore, artificial planting of Artemisia annua is an important way to solve the raw materials of artemisinin. [0003] Because Artemisia annua is sensitive to nitrogen and potassium, there is currently no ...
