Planting technology and cultivation management of Chinese Angelica

Angelica sinensis , a perennial herb belonging to the Apiaceae family, is a widely used Chinese medicinal material . Its medicinal name is Angelica sinensis, and it is also known as Qin Gui, Yun Gui, etc. In order to reduce the impact of diseases and pests on angelica, it is necessary to follow the standardized cultivation standards and operating specifications of angelica to select planting sites. Generally speaking, land with wheat and rapeseed as the primary crops is the most suitable, while land with crops such as beans and potatoes is slightly less suitable. It is required to implement a crop rotation system of at least three years to avoid continuous cropping in order to reduce the occurrence of diseases and insect pests. Let’s learn about the planting techniques and cultivation management of Angelica sinensis.

1. Transplanting and planting technology of angelica

1. Site selection and land preparation

Choose a plot with deep, loose, fertile soil rich in humus and good drainage to plant angelica. Crop rotation is an effective way to reduce pests and diseases such as tarragon. The slope of hillside land should not exceed 10°. After harvesting the previous crop, fertilize and till the land to a depth of about 20 to 25 cm, remove weeds and perennial roots, and ensure a flat surface. Since angelica likes fertilizer, base fertilizer should be applied during deep plowing, with 5,000 to 8,000 kilograms of manure and 100 kilograms of oil residue applied per mu. Generally, 2,000 kg of manure is applied per mu, the soil is plowed to a depth of about 30 cm, and the soil is plowed a second time before winter. The third time is before planting, if there is enough fertilizer , you can spread fertilizer again, harrow and level the land after deep plowing, make ridges with a width of 1.2 meters, a height of 25 to 30 centimeters, a distance of 30 to 40 centimeters between ridges, and the direction is the same as the slope.

2. Transplanting technology

Seedling selection: Choose seedlings of moderate size. Seedlings with a reed head diameter of 3 to 5 mm are high-quality seedlings, which will help reduce the early bolting rate and increase yield. Avoid using seedlings that are too large or too small to ensure survival rate and yield.

Treat the seedlings and plant them at the right time: To prevent underground diseases and insect pests, treat the seedlings with pesticides before planting, such as 50% phoxim emulsifiable concentrate and 40% carbendazim suspension, soak for about 30 minutes, and plant them after drying.

Standardized mulching and scientific planting: There are three modes of mulching cultivation technology :

Ridge-forming and film-covered ridge cultivation: suitable for flat plains, with good warming and moisturizing effects, and good drainage in the rainy season.

Film-side cultivation with mulching: suitable for hillsides, easy to operate, and has obvious warming and moisturizing effects.

Ridge forming, film covering and slanted planting on the film side: solves the problem of cultivation on the film, and has significant effects of warming and moisturizing.

2. Angelica field management technology

1. Check seedlings, thin out seedlings, supplement seedlings, and determine seedlings

20 days after transplanting, check the seedlings in time, replant any missing seedlings, choose medium and small seedlings for transplanting with soil, and water after replanting. Thin out the seedlings when they are three centimeters tall and remove sick and weak seedlings. When the seedlings are 10 cm tall, thin out the seedlings. Leave one plant in each hole for hole planting, leave about 25 cm between plants for furrow planting, and leave 1-2 plants for film planting.

2. Intertillage and weeding

Weed control is the key to obtaining high-quality yields. From seedling emergence to ridge closure, weeding should be done 3-4 times in stages. Combine soil loosening with weeding , and follow the principle of "deep in the middle and shallow at both ends".

3. Prevent bolting and remove bolting seedlings in time

Use growth inhibitors such as paclobutrazol and chlormequat to control early bolting and increase root weight and root-to-crown ratio. Remove prematurely bolting plants as soon as possible and completely.

4. Moisture management

Provide a moist soil environment. If conditions permit, carry out winter irrigation and drought prevention irrigation. Pay attention to timely drainage during continuous rainy weather in autumn.

5. Plant shaping

After closing the ridges, remove the yellow and old leaves at the bottom 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, promote root expansion and growth, and improve yield and quality.

The above is an introduction to the key points of Angelica sinensis cultivation technology. In the actual planting process, everyone should take the local environment into consideration comprehensively.
