The Latest Cultivation Techniques and Methods Tutorial for Sweet Wormwood

Sweet wormwood (Artemisia annua) is an annual herbaceous plant, and it has a certain area of both wild growth and cultivation across various parts of China. Sweet wormwood has very high medicinal value. Some time ago, the invention of artemisinin greatly promoted the development of the medical field. Artemisinin, made from sweet wormwood as a raw material, can treat malaria, heatstroke and more, and the whole plant can be used as medicine. So how should sweet wormwood be cultivated? Below, the editor brings you the cultivation techniques for sweet wormwood. Let's take a look together!

1. Site selection and land preparation

Sweet wormwood has a relatively high water requirement, so the first prerequisite for site selection is to ensure a field with sufficient water sources and good drainage and irrigation. Sweet wormwood adapts relatively quickly to soil, so it does not have great demands for soil; being disease-free and pest-free with high fertility is enough. After selecting the site, land preparation must be done well: plow the land deeply and level it to improve soil permeability and promote the plant's nutrient absorption. During land preparation, apply it together with base fertilizer. For the base fertilizer, use decomposed farmyard manure combined with an appropriate amount of phosphate fertilizer, and control the amount well according to the soil area. Then open furrows for planting, paying attention to the distance between each furrow to prevent planting too densely.

2. Raising seedlings and transplanting

After finishing land preparation, sow seeds to raise seedlings. After sowing, water an appropriate amount to promote seed rooting and germination and increase the speed of emergence. After the seedlings break through the soil, check the seedlings in time to ensure full stands and yield. When the seedlings reach about 12 cm, transplanting can begin. Do not choose rainy days for transplanting, because rainy days have more moisture and the soil is loose and muddy, which is unsuitable for seedling growth, and the incidence of pests and diseases will also increase greatly. Therefore, we should choose a sunny afternoon for planting. After planting, water thoroughly to settle the roots. Sweet wormwood has strong growth ability, so to increase yield, it can be planted appropriately densely.

3. Field management

After transplanting, sweet wormwood seedlings are relatively fragile, so we must do a good job in field management and strengthen fertilizer and water management. During the seedling stage, the number of topdressings must not be less than three times. The first is about 7 days after transplanting, applying a small amount of agricultural machinery fertilizer together with compound fertilizer. Then about three weeks after transplanting, appropriately increase the fertilizer amount, and after topdressing, cover with soil to improve water and fertilizer retention. Finally, about one and a half months after transplanting, it is necessary to hill up the soil while topdressing. Although sweet wormwood likes water, attention must be paid to water accumulation to prevent waterlogging damage. In rainy weather, drain water in time, and also do a good job of watering when it is too dry.

4. Timely harvesting

Sweet wormwood is harvested as a whole plant, so harvesting can begin when sweet wormwood grows to its strongest growth capacity. Usually, the bud stage of sweet wormwood is the best stage for harvesting. However, it should be noted that harvesting is not suitable on rainy days. The harvesting weather should be chosen when it is sunny and warm. First cut down the sweet wormwood and leave it lying in the field, then expose it to the sun for one day to disinfect it. On the second day, collect it all, knock the leaves off the plants, and continue drying the plants and leaves separately. After drying to a certain degree, it can be sold.

The above is the editor's brief introduction to sweet wormwood cultivation techniques. Growing sweet wormwood is actually relatively simple, because sweet wormwood has strong disease resistance, so the disease incidence during cultivation is relatively low, which can reduce the work of pest and disease control. Due to the successful development of artemisinin, the market for sweet wormwood will become larger and larger, and its cultivation prospects are quite good. That is all for today's introduction.
