Embodiment 1

[0010] Example 1: Planting Artemisia annua in mature land

[0011] Soil preparation: 15 days before transplanting, use a tobacco ridge machine to cultivate more than 25 centimeters of land, and make a ridge with a width of 70 centimeters and a height of 30-35 centimeters along the terrain.

[0012] Base fertilizer application: Artemisia annua waste residue: 1000 kg / mu, urea: 8 kg / mu, superphosphate: 25 kg / mu, potassium chloride: 4 kg / mu, and spread it into the field at the site preparation.

[0013] Transplanting: Select strong seedlings for transplanting from April 5th to May 5th every year, one row per ridge, one plant per hole. The suitable density of soil with good soil quality and high fertility is: the row spacing is 100 cm, and the plant spacing is 40-50 cm.

[0014] Topping: When the growth height of Artemisia annua is 100 cm, use sharp scissors to cut off the young shoots of about 3 cm from the top of Artemisia annua.

[0015] Spray foliage fertilizer: Spray boric a...

Embodiment 2

[0017] Embodiment 2: Plant Artemisia annua in abandoned land

[0018] What is different from Example 1 is that the amount of fertilization should be larger, wherein base fertilizer: Artemisia annua grass waste residue: 2000 kg-2500 kg / mu, urea: 10 kg / mu, superphosphate: 40 kg / mu, potassium chloride: 5 kg / mu;

[0019] In this example, the yield of Artemisia annua per mu is more than 220 kilograms, and the content of artemisinin can generally reach more than 7% per thousand.

Embodiment 3

[0020] Example 3: Planting Artemisia annua in newly opened land

[0021] What is different from Example 1 is that the amount of fertilization should be larger, especially to apply more organic fertilizers to improve the soil structure, wherein the base fertilizer: Artemisia annua waste residue: 2500 kg-3000 kg / mu, human excrement or pig and cow dung 3000 kg / mu or chicken manure 1500 kg / mu, urea: 12 kg / mu, superphosphate: 35 kg / mu, potassium chloride: 6-7 kg / mu; The content of artemisinin can also reach more than 7 per thousand.

Abstract

The invention relates to a method for planting sweet wormwood, which comprises that selecting ground, sowing, transplanting, fertilizing, and managing. The invention is characterized in that the fertilizer is mainly based on base fertilizer, while he base fertilizer comprises mainly the slag of sweet wormwood grass; injecting 0.05-0.20% micro elements as copper, zinc, iron, manganese, boron, and molybdenum in the growth process; in the managing process, when the sweet wormwood grows to 100cm, hitting the top of sweet wormwood to grow the branches. The invention can discharge the accumulated water easily and break the top advantage to accelerate the branch growth to improve the yield. The invention can improve the yield to 200kg each unit which is 30% higher than general method, and improve the content of sweet wormwood element to 7 / 1000, which is 20% higher than traditional method.

Description

technical field [0001] The invention relates to a high-yield cultivation technology of Artemisia annua. Background technique [0002] Artemisia annua is a traditional Chinese medicine in my country. It is used in folks to relieve heat, reduce fever, and treat colds. In the past, wild Artemisia annua was mainly picked for medicinal purposes. Chinese scientific and technological workers isolated the antimalarial monomer Artemisinin for the first time in the 1970s. Artemisinin is the first drug of choice for the treatment of malaria in my country that has been internationally recognized and recommended by the World Health Organization. Symptoms also show potential promise. At present, the demand for artemisinin drugs is increasing. The content of artemisinin in wild Artemisia annua in most parts of the world is less than 0.5%, which has no industrial utilization value. Wild Artemisia annua resources with extraction value are mainly distributed in the south of the Yangtze Ri...
