Planting method of Artemisia annua L.

Artemisia annua L. is a kind of wild vegetable with very high nutritional content. Its main edible part is its fresh and tender stalk, which is usually used to stir-fry bacon, of course, it can also be stir-fried, and the taste is very fresh. Now the output of Artemisia annua on the market is not very much, so we are generally rarely able to eat it, so today's pro-farm network has brought us a welfare, that is, the planting method of Artemisia annua. Come and have a look with the editor.

1. Sowing seeds at the right time

Because chrysanthemum chrysanthemum has several sowing methods, so the sowing methods are different, and the sowing time is also different. if we choose to sow with tubers, we can plant all the year round, but if we choose planting and sowing, then it is best to choose early March every spring, and if we choose stem pressing sowing, it is best to choose from the end of July to the middle of August. And ramet sowing is best in early May, and finally there is a cutting sowing method, preferably at the end of June, each sowing method must remember to plant at the right time, so that the survival rate will be much higher.

2. Select improved varieties

Now there is not only one variety of Artemisia annua, because the temperature and climate changes in each place are different, so it is constantly improved in the process of planting, so Artemisia annua has derived different resistant varieties according to different soil environments. for example, it is more suitable to plant Artemisia annua when the weather is drier in autumn, and you can sow any Artemisia annua in spring. Artemisia annua with finer leaves will be selected in summer, so that the planted Artemisia annua will be of higher quality and higher yield.

3. Soil preparation and fertilization

Artemisia annua L. is a kind of wild vegetable, so it has a strong ability to adapt to the environment, so basically the land can be planted, but we try to plant it in places where the soil is fertile and close to the water source. We usually have to prepare the land about 10 to 15 days in advance, because we still need to dry the soil after finishing the land, and the basic fertilizer is mainly based on farm rotten fertilizer, which requires an average of about 4,000 to 5,000 jin per mu, and then mixed with 1,000 jin of compound fertilizer and urea for deep application. finally, ridging and ditching is done, which is conducive to water management in the field.

4. Field management

In the summary of the whole growth process of Artemisia annua, it is particularly important to mention that management. First of all, we need to replenish the seedlings with lack of seedlings in the field to ensure the evenness of the seedlings in the field. After planting, the seedlings in the field need to be watered, fertilized and weeded for the first time. We usually use sprinkler irrigation. The first fertilization is mainly to promote the growth of Artemisia annua, so we mainly use urea. Or it can be replaced by fecal and urine water, which can also save the time spent on watering. The best thing to do before watering and fertilizing is to get rid of the weeds in the field and give the land air by the way, which can increase the absorptive capacity of the land and make Artemisia grow faster. From sowing to harvest, at least three times of watering, fertilization and weeding are required, each at the same time.

5. Timely harvest

The growth cycle of Artemisia annua is relatively short. Generally speaking, the first harvest can be carried out in about a month. Why is it the first harvest? it is because you only have to cut off the new twigs of Artemisia annua each time, leaving the rest. After another harvest, fertilizer is applied once, basically after three or four days, it can be harvested again and again, knowing that the service life of Artemisia annua has been exhausted. It needs to be replanted.
