Problems solved by technology

It can be seen from this that the seeds of Artemisia annua are sown directly on the field ridge, the germination rate is low, and the seedling rate is lower
However, the method of transplanting seedlings will greatly increase the cost, and it is time-consuming and labor-intensive.

Abstract

The invention belongs to the technical field of nutrient soil, and discloses special nutrient soil for artemisia annua in sowing and seedling stages. The nutrient soil comprises, by weight, 30-45 parts of field surface soil, 15-25 parts of dry cow dung, 8-18 parts of sand, 8-13 parts of vermiculite, 6-15 parts of diatomite, 10-16 parts of modified charcoal, 10-15 parts of inorganic fertilizer, 0.5-1.2 parts of medium trace element, 5-10 parts of plant nutrition additive and a proper amount of water. The nutrient soil is specially prepared according to the growth characteristics of artemisia annua in the sowing and seedling stages, the germination rate of artemisia annua seeds is increased, nutrients are provided for artemisia annua seedlings, the seedling rate of the artemisia annua is increased, and the cultivation cost of the artemisia annua is greatly reduced. A preparation method is simple, easy to operate and high in feasibility.

Description

technical field [0001] The invention belongs to the technical field of nutrient soil, and in particular relates to a special nutrient soil for sowing and seedling stage of Artemisia annua. Background technique [0002] Artemisia annua Linn (Artemisia annua Linn), also known as Artemisia annua, is an annual herb of the genus Artemisia in the Asteraceae family. It grows in wilderness, hillsides, roadsides and river banks, and is distributed throughout the country. Its active ingredient, artemisinin, has the characteristics of high efficiency and low toxicity in antimalarial, and is listed by the World Health Organization as the first choice drug for the prevention and treatment of malaria in the world. According to statistics, the national malaria areas are distributed in more than 100 countries, with 400-500 million clinical patients and 2-3 million deaths every year. At present, the world's demand for artemisinin is about 200 tons, and the demand continues to increase. my c...
