Cultivation techniques of Artemisia chinensis

Yinchen, also known as oregano, Tian Nai Li, Ma Xian, wormwood, Artemisia annua, etc., are perennial herbs or semi-shrubs of the Compositae family oregano, often born in low-altitude riverbanks, coastal wet sand, roadsides and low hillside areas. Chinese people still have the habit of using rice noodles as Yin Chen cakes and dumplings. Let's take a look at the cultivation techniques of Artemisia chinensis.

Growth habit

Yinchen prefers a warm and humid climate with strong adaptability. It is suitable for cultivation in sandy loam with sunny, deep soil layer, loose and fertile soil and good drainage. The requirement of soil is not strict, general soil can be cultivated, but alkaline soil and sandy soil are not suitable for cultivation. Farm manure is applied before turning the land. Because the seeds of Elsholtzia splendens are very small, the land must be leveled and raked fine.

Reproduction method

The direct seeding method of Artemisia chinensis was sown in March in spring. after mixing the seeds with fine sand, the seeds were sown according to the row spacing of 25 × 20 cm. Strip sowing opened a trench according to the row spacing of 25 cm, and sowed the seeds evenly. Before sowing, seed dressing with new high fat membrane and seed coating agent were used to ward off underground diseases and insects, isolate virus infection, strengthen respiratory intensity and improve seed germination rate. Spraying soil surface with 600 × 800 liquid of new high fat film after soil preparation can preserve soil moisture, prevent evaporation, prevent sun and drought, prevent soil layer from hardening, suffocate and isolate the source of diseases and insect pests, and increase the rate of seedling emergence.

Field management

After the emergence of wormwood seedlings and time seedlings, ploughing and weeding, irrigation and fertilization, and spraying new high-fat film on the plant surface to enhance fertilizer efficiency, prevent bacterial infection, improve the ability to resist natural disasters, improve photosynthesis efficiency, and protect the growth of grain seedlings. And timely spraying Zhuangtuanling makes the plant stem stout and the plant luxuriant. During the growth period, the weeds were ploughed and weeded 2 times a year, combined with topdressing human feces and urine for 2 times.

Pest control

The diseases of Artemisia chinensis seedlings include root rot, Sclerotinia sclerotiorum, insect pests, etc., and attention should be paid to prevention and control during cultivation. After 4-7 days of bleeding period and callus formation period of about 20 days after harvest, new buds began to differentiate and multi-branched plants were formed. From the bleeding period to the differentiation of new buds, it should not be watered to prevent rotting roots. At the same time, it is necessary to improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.
