Cultivation techniques of Artemisia mandshurica

Artemisia mandshurica is a biennial herb of Leguminosae, which is taller and can reach 35 cm. Artemisia mandshurica is mainly distributed in China and grows in the shady and humid zone. Artemisia mandshurica is a very important nectar plant, which is usually planted as green manure and forage. However, the seed of Ziyunying is a kind of traditional Chinese medicine, which has the effects of tonifying qi, solidifying essence, clearing heat and diuresis. There are cultivation in all parts of our country. Today, the editor has brought you the cultivation techniques of Ziyunying. Let's have a look!

1. Seed treatment

Ziyunying originally has a wide range of wild quantity, so there is no great requirement for soil, so you can choose soil with sufficient water, cool, moist and fertile soil. Before sowing, the seeds should be dried for about 4 hours, and then the wax on the surface of the seeds should be wiped off to promote the seed to absorb water and germinate. After treatment, the seeds are put into salt water to pick out useless seeds such as withered and diseased seeds floating on the surface of the water. Then soak the healthy seeds in human urine for 7 hours, air-dry after soaking, then mix the seeds with calcium magnesium phosphate fertilizer, and then sow the seeds at the right time.

2. Sowing seeds at the right time

The sowing time of Artemisia mandshurica is usually in the early autumn every year, when the temperature and humidity are very suitable for the development of seeds, which is conducive to seed germination and emergence. Sowing time has a great effect on the growth of Artemisia mandshurica. If sowing is too early, the symbiosis period with fertilizer is long, and the growth of seedlings is weak and hindered after emergence. If sowing too late, the temperature will gradually decrease, the seeds will enter the dormant period, the germination rate will decrease, and the freezing injury will occur easily after emergence, and the overwintering survival rate will be insufficient. When sowing, we should pay attention to the sowing density and spread evenly to ensure that the seedlings are uniform.

3. Protect seedlings and promote seedlings

If you use rice fields to sow seeds, avoid rotten fields when harvesting rice. Sow seeds in time after harvest, and then cover rice straw on Artemisia mandshurica to increase the temperature, strengthen the water retention of soil, and promote the growth and branching development of seedlings. Then do a good job of weeding, weeds is an important factor affecting the growth of seedlings, timely weeding is the most important work to ensure the whole seedling. If weeding is not done well, weeds will rob the growth and nutrition of seedlings, resulting in malnourished growth of seedlings, and in serious cases, seedlings may die. Therefore, in order to ensure the healthy growth of Artemisia mandshurica, we must do a good job in protecting and promoting seedlings.

4. Field management

Ziyunying is afraid of both drought and waterlogging during the growth period, especially in the seedling stage, we should pay attention to drainage, if there is too much water, it will easily lead to rotten buds and rotten seedlings. Improper water management will affect the growth of plant roots and lead to yellow leaves and fallen leaves. Therefore, we should control the management of water according to the growth stage and weather and other factors. Ziyunying has a great demand for nutrition, so it is necessary to apply farm manure in time after emergence to improve the resistance of seedlings. Then in December, topdressing farm manure and calcium superphosphate and other fertilizers to improve the cold resistance of seedlings and reduce freezing damage. The Beginning of Spring applied available nitrogen fertilizer to ensure the normal growth of Ziyunying according to the growth of seedlings.

The above is a brief introduction to the cultivation techniques of Artemisia mandshurica. The cultivation time of Artemisia mandshurica is generally in autumn, so the overwintering work of seedlings is very important. If mismanaged, the phenomenon of seedling death is very important, the survival of seedlings will be very poor, and the incidence of diseases and insect pests will increase significantly. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
