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. It is cultivated in all parts of our country. Today, let's talk about the planting technology of Ziyunying.

1. Timely fertilization

The fertilization of Ziyunying is mainly phosphate fertilizer and potassium fertilizer, and nitrogen fertilizer can be added properly. Different fertilizers were applied in different periods, generally, calcium phosphate and manure were applied in late autumn to promote early root nodules and early seedlings; potash or plant ash were applied before and after the Winter Solstice to enhance cold tolerance; urea was applied after the Beginning of Spring to promote branch and leaf growth.

2. Pressing youth at the right time

Ziyunying is usually pressed green more than ten days from the flowering period to the transplanting period, and for large-scale breeding, an appropriate amount of lime is evenly applied per mu to promote plant decay to neutralize acidity.

3. Timely watering

Ziyunying likes a warm and humid environment, especially in the growing period, but we should also pay attention to avoid stagnant water, so it is very important to control the amount of water, and we also need to spray water frequently to keep the environment moist.

4. Sowing in right amount at the right time

According to the cool nature of Ziyunying, it can be sown more than 20 days after the harvest of late autumn rice. When sowing, it is necessary to pay attention to the soaking, drying and germination of the seeds, so as to improve the germination rate.

5. Mix with rhizobium

Mix the rhizobium when the seeds are budding and whitening, that is, mix the seeds with cold porridge soup and then mix the seeds.

6. Strengthen maintenance and management

For large-scale economic farming of Artemisia mandshurica, ditches should be opened after the late rice harvest, including Huantian ditch, chamber ditch and cross drainage ditch to keep the soil moist and avoid stagnant water. In addition, we should also pay attention to the prevention and control of diseases and insect pests, using carbendazim or carbendazim for powdery mildew, dimethoate for aphids and trichlorfon or rice vinegar and saccharin for armyworm. In addition, attention should be paid to avoid livestock harm.
