Method for artificially culturing artemisia annua linn in high altitude areas

Abstract

The invention relates to a method for artificially culturing artemisia annua linn in high altitude areas and belongs to the technical field of agricultural science. The method mainly comprises the followings steps: the diameter of soil particles of a seedbed is smaller than 0.2cm, the width of furrow is 100cm, the height thereof is 15 to 20cm and the length is 5 to 10m; the seeding time is the end of February to early March and the seeding quantity is 200g / mu; transplanting is carried out when the temperature of the seedbed is 15 DEG C to 30 DEG C, the humidity is 40 to 50 percent, the height of the plant is 10 to 15cm and the length of the root is more than 5cm; the center width of a ridge and furrow is 0.8 to 1m and the depth of the ridge and furrow is 30 to 40cm; the spacing between rows is 0.40*0.80m or 0.50*1.0m and 1300 or 2000 artemisia annua linn is planted in each mu; 0.7si of plastic film are used for mulching the artemisia annua linn along furrow surface after permanent planting; seeds are compensated after ten days, watering is carried out for once to twice everyday, and after transplanting for 7 days, 10 to 15kg of fertilizers are applied for each mu or 0.3 percent of liquid fertilizers are poured and applied; the humidity of the field in seedling stage is kept between 60 and 70 percent; additional fertilizer are applied for twice; 5 to 10kg of N.P.K compound fertilizer is used in squaring stage; and pouring and applying are carried out after 1000kg of water is watered. The invention has simple and convenient operation of the method and short seedling stage, can effectively improve the yield of artemisia annua linn and the content of active components and is suitable for artificial culturing of artemisia annua linn in the areas with altitude more than 1900m.

Description

Technical field: [0001] The invention relates to a method suitable for artificially cultivating Artemisia annua in high-altitude areas above 1900 meters, and belongs to the technical field of agronomy. Background technique: [0002] Artemisia annua L. is an annual herb of the genus Artemisia in the Asteraceae family, and is an important raw material plant for extracting artemisinin. Artemether made from artemisinin has high antimalarial activity, and has been included in the WHO "Essential Drugs Handbook" as a special Chinese medicine variety for treating malaria. There are not many Chinese medicine varieties certified by the US FDA. Extracting artemisinin from natural Artemisia annua plants is currently the only source of artemisinin. Due to the sharp increase in the global market demand for artemisinin-like drugs, wild Artemisia annua resources can no longer meet the needs of pharmaceutical companies, and artificial domestication has become an industrial The inevitable c...

Problems solved by technology

There have been relevant research reports on the artificial cultivation of Artemisia annua in China, and relevant scholars have shown that [1-6] : Sowing amount, cultivation density, base fertilizer type and top dressing, and harvesting period all have significant effects on the yield and artemisinin content of Artemisia annua, but there is no report on the research on the film-mulched cultivation technology of Artemisia annua

[0003] Through literature search, there is no public report identical with the present invention
