Which month is the best to plant angelica?

Angelica sinensis , as a perennial herb of the Umbelliferae family, plays an important role in medicinal materials. It is also known as Qin Gui, Yun Gui, etc. and has many functions. So which month is the best to plant angelica?

Which month is the best to plant angelica?

The best time to plant angelica is usually in spring and fall. Specifically:

In high-altitude areas with lower temperatures, it is suitable to sow in early to mid-June. In low-altitude areas with slightly higher temperatures, it is suitable to sow from mid-July to early August.

Due to the humid climate in the south, the time for planting angelica is mostly concentrated in autumn, that is, from September to November. In the northern region, due to its vast territory, the best planting time varies slightly in different regions, but it is basically between September and November.

Angelica planting and cultivation management

1. Transplanting and planting

1. Site selection and land preparation

The land for planting angelica should be deep, loose, fertile, rich in humus, and have good drainage. In order to reduce diseases and pests, it is recommended to implement crop rotation, with beans as the best previous crop. It can also be rotated with crops such as wheat and potatoes, with a rotation cycle of at least 3 years. The slope of the slope should not exceed 10°. After harvesting the previous crop, fertilize and till the land to a depth of 20 to 25 cm to ensure a flat surface. Since angelica likes fertilizer, base fertilizer should be applied during deep plowing, with 5,000 to 8,000 kg of manure and 100 kg of oil residue applied per mu. If there is enough fertilizer , you can spread it again and deep plow before planting, then harrow and level the land to make ridges 1.2 meters wide and 25 to 30 centimeters high, with a spacing of 30 to 40 centimeters between ridges, and the direction should be consistent with the slope.

(ii) Transplanting technology

1. Seedling selection

The quality of seedlings directly affects the early bolting rate. High-quality seedlings should be 3 to 5 mm in diameter. Such seedlings have a low bolting rate and high yield. Avoid using seedlings that are too large or too small.

2. Seedling treatment and planting

Seedlings should be treated with pesticides before planting to prevent underground pests and diseases. Use chlorpyrifos emulsifiable concentrate and carbendazim suspension to make a solution, soak the seedlings for about 30 minutes, and plant them after drying. The planting time is generally between the Spring Equinox and the Grain Rain, that is, from late March to mid-April.

3. Film covering and planting

There are three modes of mulching cultivation technology: ridge-forming and mulching cultivation on ridges, ridge-forming and mulching cultivation on the side of the film, and ridge-forming and mulching cultivation on the side of the film. Each mode has its own characteristics and applicable environment.

2. Field Management Technology

(I) Checking seedlings, thinning, supplementing seedlings, and finalizing seedlings

20 days after transplanting, angelica seedlings will emerge one after another, and the seedlings should be checked and replanted in time. When the seedlings are three centimeters tall, thin them out and remove sick and weak seedlings. Transplant when the seedlings are 10 cm tall.

(II) Cultivation and weeding

Weeding is the key to ensuring high-quality and high-yield angelica. From seedling emergence to ridge closure, weeding should be done 3-4 times in stages.

(III) Preventing bolting and removing bolting seedlings

Bolting will cause the angelica roots to lose their medicinal value. Growth inhibitors can be used to control early bolting, and bolting plants can be removed promptly.

(IV) Water management

Angelica requires a moist soil environment. Winter irrigation can be carried out before transplanting, and drought prevention irrigation can be carried out in early summer, but heavy watering should be avoided.

(V) Plant shaping - removing old leaves

After ridge closing, yellow old leaves should be removed in time to reduce nutrient consumption and improve ventilation and light conditions.

(6) Soil cultivation

In the middle and late stages of growth, loosen the soil and build up the roots to provide a loose soil environment for root expansion and growth.

The above are the key points of Angelica sinensis planting technology and field management. I hope it will be helpful to growers. According to the climatic conditions in different regions, March to April in spring and September to October in autumn are the best times to plant angelica.
