The following editor brings you the cultivation techniques of Artemisia annua. Let's have a look!

1. Land selection and preparation

The water demand of Artemisia annua is relatively large, so the primary premise of land selection is to ensure adequate water supply and good drainage and irrigation. Artemisia annua soil adapt quickly, so there is no great demand for soil, disease-free and harmless, high fertility. After selecting a good site, we should do a good job of soil preparation, plough the depth of the ground flat, improve the permeability of the soil and promote the nutrient absorption of the plant. Soil preparation is applied together with base fertilizer, which uses mature farm manure combined with appropriate amount of phosphate fertilizer, and the dosage is controlled according to the soil area. Then trench planting, pay attention to the distance between each ditch, to prevent planting too dense.

2. Seedling raising and transplanting

Sowing and raising seedlings after soil preparation, and watering appropriately after sowing to promote seeds to take root and sprout and improve the speed of seedling emergence. After breaking the soil, the seedlings should be checked in time to ensure that the seedlings and yield, when the seedlings to about 12 cm can begin to transplant. When transplanting, you can not choose rainy days, because there is more water in rainy days, the soil is loose, which is not suitable for the growth of seedlings, and the incidence of diseases and insect pests will be greatly increased. Therefore, we should choose to plant in the sunny afternoon. After planting, the growth ability of Artemisia annua is strong, so it can be planted densely in order to increase the yield.

3. Field management

Artemisia annua seedlings are relatively fragile after transplanting, so we should do a good job in field management and strengthen fertilizer and water. The times of topdressing at seedling stage should not be less than three times. For the first time, about 7 days after transplanting, a small amount of agricultural machinery fertilizer was applied and combined with compound fertilizer. Then, the amount of fertilizer should be increased about three weeks after transplanting, and then the soil would be covered after topdressing to improve the water and fertilizer conservation. Finally, one and a half months after transplanting, we need to cultivate the soil and fertilize at the same time. Although Artemisia annua likes water, it should pay attention to stagnant water to prevent waterlogging, timely drainage in rainy weather, and watering when it is too dry.

4. Timely harvest

The harvest of Artemisia annua is to harvest the whole plant, so it can be harvested when it grows to the strongest growth ability, usually in the bud stage of Artemisia annua is the best stage of harvest. However, it should be noted that it is not suitable to harvest in rainy days, and when the harvest weather is sunny and warm, cut down the artemisia annua to pay in the field, and then expose it to the sun for a day of disinfection. The next day, all the mobile phones knocked down the leaves on the plant, and the plant continued to dry separately from the leaves. After a certain degree of sun exposure, it can be sold.

The above is a brief introduction to the cultivation techniques of Artemisia annua. Planting Artemisia annua is actually relatively simple, because the disease resistance of Artemisia annua is strong, so the incidence rate in the planting process is relatively low, so it can reduce the work of pest control. Due to the successful development of artemisinin, the market of Artemisia annua will be bigger and bigger, and its planting prospect is quite good. That's all for today's introduction.
