Planting technology and cultivation management of Atractylodes lancea

Atractylodes lancea, as a herbaceous plant rich in medicinal value, prefers to grow in sunny environments, especially on the southern slopes of mountainous and hilly areas. The ideal temperature range for its growth is not lower than 15℃ and not higher than 22℃. Let’s learn about the planting techniques and cultivation management of Atractylodes lancea.

1. Preparation of the planting site

Choose virgin land or reclaimed land , requiring sandy loam with good ventilation, coolness, good drainage and sufficient fertility. After selecting the plot, apply 50 kg of compound fertilizer and 50 kg of phosphate fertilizer per mu, deep plow 15 to 20 cm, harrow and level it, and then mechanically lay 80 cm wide black thickened ground film, keeping the distance between films at 30 to 40 cm. When preparing the land, you should ensure smooth drainage according to the terrain, avoid waterlogging, and apply sufficient base fertilizer to ensure soil fertility.

2. Seedling preparation

Choose healthy Atractylodes tubers planted last year as seeds. They should be free of pests and diseases, with many tuber buds and no rotten roots. After cutting off the hairy roots, cut the tubers into 3 to 4 cm long pieces with 2 to 3 buds, preferably weighing about 15 to 20 grams. The incision should be as small as possible to reduce trauma. Give priority to tubers that are free of pests and diseases and have many buds. It is better to cut domestically grown Atractylodes into pieces, while wild Atractylodes can be directly broken apart.

Soak the cut seedlings in 1000 times diluted 50% carbendazim or 70% thiophanate-methyl for 3 to 5 minutes, or spray directly for disinfection. After disinfection, wait for the seedlings to dry before planting. Be sure to disinfect the seedlings and dry them before transplanting.

3. Planting

The best time for transplanting is from November to April of the following year, and transplanting should be done on sunny days. Planting in winter is better than in spring, especially from November to before the soil freezes. The soil needs to be kept moderately moist, but not too wet, so that it will fall apart when you squeeze it into a ball and then let go.

Plant 3 rows on 80 cm wide mulch with 20 cm row spacing and 15 cm plant spacing. Use a garden shovel to make holes 8 to 10 cm deep, put the seedlings in with the buds facing up and the fibrous roots facing down, and cover with 3 to 5 cm of soil. Be careful not to cover the soil too thickly.

4. Field Management

1. Weeding

In April and May, after the seedlings have basically emerged, weeding should be carried out in time. Weeding should be done on sunny days, while loosening the soil, cultivating the soil and clearing the ditches. Weeding should be done several times before the beginning of the dog days. Weeding is not suitable during the hot and humid season after the beginning of the dog days. Weeding should be avoided on rainy days or when there is dew. When entering the second harvest year, continue weeding according to the growth conditions.

2. Topdressing

Apply fertilizer in time to ensure soil fertility.

3. Pest and disease control

Black spot disease mainly harms leaves and affects yield. White rot mainly harms underground rhizomes, causing plant death. Root rot damages the rhizomes and causes the death of the plant.

Prevention and control methods: Disinfect seedlings and use pesticides for prevention and control. Spray fungicides such as carbendazim, thiophanate-methyl, mancozeb , etc. every 10 to 15 days. When plants with root rot and white rot are found, the entire plant and the surrounding soil must be dug up, placed in plastic bags and sent to a place far away from the planting base for destruction.

5. Harvest

The harvesting is carried out from November every year to March or April of the following year. Choose sunny days to harvest and be careful to avoid breaking the rhizomes. After cleaning the above-ground part, it should be dug and processed in time. When drying and removing soil from the roots, avoid using open flames for grilling.

The above is a detailed introduction to the planting technology and cultivation management of Atractylodes lancea. I hope it will be helpful for everyone's planting. If you have other questions, you can also ask them.
