The harvest process is as follows: dig up the remaining seed plants and cut off the roots; tie up the branches and leaves with seeds and hang them in the shade under the eaves for 20 to 30 days, and the seeds are really mature and dried for a day or two, and the seeds are beaten out by corresponding machinery and stored for the next planting.

What are the breeding methods of Atractylodes macrocephala Koidz?

1. Sowing and raising seedlings

Sowing is the first step in planting Atractylodes macrocephala Koidz. Atractylodes macrocephala Koidz mainly depends on seed propagation. Generally, the best time to sow Atractylodes macrocephala Koidz is from late March to early April. The seedlings in the seedling bed will be transplanted to the field from winter to the following spring. When sowing, the grower should level the land and use the ridging machine to cultivate it, so as to ensure the smooth drainage of the field, avoid stagnant water in rainy days and affect the growth of Atractylodes macrocephala Koidz. Then, after soaking the seeds in warm water for about 25 ℃ for 24 h, the seeds were evenly sprinkled into the ditch, then covered with soil and watered. In order to ensure the yield and quality of Atractylodes macrocephala Koidz, 5 kg seeds should be sown in every 667m 2 field. After sowing Atractylodes macrocephala Koidz, a little wheat straw should be covered on the seedbed to resist drought and preserve soil moisture and improve the germination rate of seeds. Usually when the temperature reaches 20 ℃, the seedlings can emerge in 7 days.

2. Transplanting

When transplanting seedlings, hole planting or strip planting should be carried out according to row spacing of 30-40 cm and plant spacing of 10-12 cm, and the planting depth is about 6 cm. When planting seedlings, the seedlings should be placed on the side, the buds face up, and the soil at the bottom of the ditch should be covered with soil mixed with calcium superphosphate or cake fertilizer, and the soil at the bottom of the ditch should be cultivated on the border surface, gently suppressed, and watered thoroughly, so as to effectively ensure the survival rate of seedlings.

3. Seedling stage management

Seedling management is an important step to strengthen seedlings. When the seedling height of Atractylodes macrocephala Koidz is about 3 cm, the grower can remove the wheat straw and interplant the seedlings to provide growth space for the seedlings and strengthen the seedlings. When the height of the seedling was 10-15 cm, weeding, loosening the soil, and intersprouting again. It should be noted that seedlings should be avoided after rain or when the dew is not dry, so as not to break the seedlings. In addition, this stage is the growing period of seedlings, and there is a great demand for water. Therefore, the soil should be watered and fertilized frequently, the soil nutrition should be increased, urea 15 kg/667 m 2 and compound fertilizer 30 kg/667 m 2 should be applied, and the soil should be watered immediately after fertilization to make the soil fully absorb fertility. During the period of Frosts Descent, it can be harvested. When digging out the rhizome, you should avoid injuring the root, dry the rhizome for a day or two, and store the rhizome in wet fine sand.

The above is the introduction of Atractylodes macrocephala Koidz. After harvesting, Atractylodes macrocephala Koidz should be transported back to dry or dry in time to avoid stacking, resulting in fever and decay of Atractylodes macrocephala. During the drying period, Atractylodes macrocephala dried to about 80%, remove fibrous roots, coarse bark and sediment, and dry again.
