Cultivation and planting techniques of Rhizoma Atractylodes

Selecting land for fertilization: we should choose loose and fertile soil with good drainage and irrigation conditions for planting, and then apply sufficient base fertilizer. Seedling setting: the seedlings of direct seeding Atractylodes lancea grew to 5-6cm, and when the seedlings reached 10-15cm, the seedlings were fixed. Weeding in the middle tillage: weeding regularly and loosening the soil properly. Timely watering: keep the soil moist before and after emergence and immediately water the seedlings after thawing in early spring. Reasonable topdressing: fertilization can be carried out in seedling stage, June-July and October.

1. Reproduction methods of Atractylodes lancea

1. Seed propagation

Generally, seedlings are raised at the end of April, first select the seedbed, and then sow with the method of strip sowing or sowing, the sowing amount per mu is about 3-4 kg, and cover a layer of grass after sowing. After the seedlings grow, the grass will be removed, and the seedlings can be planted when they grow to 10cm or so.

2. Ramet propagation

When the buds of Atractylodes macrocephala is about to germinate in the middle and lower stage of May, dig out the old seedlings, shake off the soil, and then cut the rhizome into several small pieces with 1-3 buds, which can be transplanted.

3. Rhizome propagation

The harvested rhizome is cut off with buds, and after the cut is dried, it can be planted in holes according to the row spacing 20cm and plant spacing 20cm, one piece in each hole, and then compacted with soil.

2. Planting techniques of Atractylodes lancea

1. Land selection and fertilization

Atractylodes lancea seedbed should be made in sandy loam or humus loam with loose fertile soil, sufficient light, deep soil layer and good drainage and irrigation conditions. about 2000 kg of farm manure can be applied per mu, usually using large ridge and high bed technology.

2. The seedlings are fixed

Direct seeding Atractylodes lancea seedlings can start to grow to 5-6cm, and when the seedlings grow to 10-15cm, the seedlings can be fixed according to the spacing of 15-20cm and 25cm. Hole sowing can keep about 2-3 strong seedlings per hole, and the number of transplantable seedlings per mu is about 1.2-15000.

3. Ploughing and weeding

Atractylodes lancea should strengthen its management at the seedling stage, weed regularly and loosen the soil properly. after transplanting, it needs to be ploughed and weeded about 3-4 times a year, and the soil should be loosened every 2 months, which can be carried out together with soil cultivation and fertilization.

4. Timely watering

Atractylodes must keep the soil moist before and after emergence, which is beneficial to improve the emergence rate and promote the growth of seedlings. The seedlings should be watered immediately after the soil is thawed in early spring and watered in time in the dry season. There is no need to water the plants after they grow out.

5. Reasonable topdressing

In the seedling stage of Atractylodes macrocephala, about 2000 kg of rotten and thin farm manure can be applied per mu, 2500-3000 kg of rotten farm manure can be applied in June-July, and 15 kg of superphosphate can be applied together. In October, it can be ditched and fertilized between rows, mainly into mature compost or barnyard manure, watering and covering soil after fertilization.

6. Pick buds and leave seeds

Atractylodes lancea is generally planted in fertile and loose soil. In the budding stage, flower buds can be properly removed to avoid nutrient loss, which is more conducive to the cultivation of excellent seeds and seedlings.

7. Timely harvest

Atractylodes can be harvested 3-4 years after sowing or 2-3 years after transplanting. After the underground stems and leaves have dried up in spring or autumn, the roots and stems can be dug in sunny days.
