The latest planting method of Artemisia chinensis

Artemisia annua L. is also called Artemisia annua L., and it is also called Artemisia annua L. in some places. It originated in Europe. It is very rich in nutrients and can be used to clear heat and remove dampness and reduce anthrax. Regular drinking with herba wormwood is of great benefit to the liver and gallbladder, and can directly prevent cancer cells from entering the liver system. At present, the cultivation of Artemisia mandshurica is not very common in China, mainly in the northwest and Inner Mongolia, so today let's take a look at how to plant it.

1. Seed selection and soil preparation

There are two main varieties of wormwood, namely, French and Russian. The climate in the area where the grass is planted is generally warm and humid. At the same time, the planting land has sufficient light, fertile soil, loose soil, sufficient water source and good drainage and irrigation soil. Soil preparation should be at least 20 to 25 centimeters deep, and sprinkle enough organic fertilizer, cake manure and barnyard manure as base manure. Finally, we should pay attention to the trenching in the field, ditches blend with each other, which is conducive to drainage and drainage.

2. Sowing seeds at the right time

Wormwood grass is usually sown in spring every year. There are two methods of sowing, seed sowing and plant propagation. Transplanting is needed in the later stage of seed sowing, and ramet propagation basically plans the planting density at the time of planting. Seed sowing is usually carried out from February to March. Before sowing, the seeds should be evenly mixed with fine river sand, while ramet propagation is usually planted in March and April.

3. Transplanting and planting

When the wormwood grass grows to about 10 to 15 centimeters, it can be transplanted, and the density is generally planted according to the spacing of 25 centimeters between rows and 20 centimeters between plants. When planting, you need to irrigate the field with water, and then dig holes to plant.

4. Field management

About a week after planting, the basically planted wormwood grass that can survive has survived, and those that have not survived can no longer survive, so it is necessary to replenish the seedlings in time. After seedling replenishment, topdressing should be carried out reasonably, which can promote the growth of wormwood grass, make the field wormwood grass look neat, and combine ploughing and watering together, which can not only promote the absorption of nutrients, but also enhance the permeability of the soil and accelerate the growth rate of wormwood grass. The main part that can be used is its stems and leaves, so when we topdressing, we mainly use fertilizers to promote the growth of stems and leaves, such as nitrogen fertilizer, feces and urine water, and so on. Each fertilization can be combined with the watering of the mid-tillage and weeding industry.

5. Pest control

The main diseases of Artemisia are root rot and Sclerotinia sclerotiorum. Root rot is mainly harmful to the roots of wormwood grass, resulting in the decay and death of the whole plant, of which the most fundamental reason is improper water management, which can be controlled by chlorothalonil. Sclerotinia sclerotiorum is a fungal infection disease, we can use Bordeaux solution for prevention and control, while scientific fertilization to enhance plant resistance. The most common pests are ground tigers, leaf rollers and aphids, all of which are sprayed with special agents, such as trichlorfon, dimethoate milk, dichlorvos and so on.

At present, the planting area of wormwood in our country is not very large, which is just enough to meet the needs of the market, but with the development of economy, the planting industry of wormwood will have a new ladder, so friends who want to plant wormwood can understand this article. let yourself plant high-quality wormwood.
