Atractylodes macrocephala: Atractylodes macrocephala belongs to perennial herb, up to 60 cm high, nodular rhizome. Stems erect, all smooth and glabrous. Leaves alternate, leaf blade pinnatifid, lateral lobes oblanceolate, elliptic or long elliptic, terminal lobe larger than lateral lobes, all leaves thin, papery, both sides green, glabrous, head solitary stem tip, bract green, needle-pinnatifid. Involucre broadly campanulate, apical purplish red. Achenes obconical, blooming and fruiting from August to October. Distributed in Jiangsu, Zhejiang, Fujian, Jiangxi, Anhui, Sichuan, Hubei and Hunan, this species is cultivated. This species also has many commercial names, such as according to the rhizome shape of crude medicine, or crane-shaped, golden thread, or Atractylodes macrocephala, named according to the place of origin, such as Huizhou, according to the season when the rhizome was unearthed, such as winter. The quality of Yuzhu (Zhejiang Yuqian) is the best. It has the effect of dryness and dampness, resolving turbidity and relieving pain.

Used in other industries and all aspects of daily necessities, such as cosmetics, seasonings, veterinary drugs, etc., since China's accession to the WTO, the export volume of Atractylodes macrocephala Koidz has increased year by year, with a reported total export of 23760 tons for 9 consecutive years. the market demand is huge and shows an increasing trend, and the planting area must be maintained at about several hundred thousand mu in order to meet the market demand.

(1) seed selection, select new species with full grains and no diseases and insect pests, and soak them in warm water of 30 degrees Celsius.

(2) soil: sandy loam with deep soil layer, medium fertility, good drainage and cool ventilation was selected as the land for planting Atractylodes macrocephala Koidz.

(3) fertile land: select the ripe cultivated land with deep soil layer, groundwater level below I meter, drainage and irrigation soil; deep ploughing 40cm. Spread farm manure evenly on the pre-planted land, after applying agricultural fertilizer, turn the land over again, then apply farm manure, spread the fertilizer evenly, then turn over the land deeply, and then rake the land flat.

(4) make a bed 1 m wide and 4 m long, with drainage ditches at both ends of the border

(5) Base fertilizer: apply base fertilizer in the finished border, the amount applied per mu is 150kg, the specific method is: put farm manure at the source of water, take it to Wazhou through water flow to irrigate and fertilize.

(6) Seedling reduction: choose the Atractylodes macrocephala seedlings raised in the same year with full top bud head, uniform size, developed root group and large round tail. Keep the row spacing as 20cm and plant spacing as 15cm as possible, and water the seedlings of Atractylodes macrocephala Koidz after transplanting.

(7) removal of impurities: weeds were removed, 7cm was hoed shallowly, soil was loosened and uniconazole was sprayed twice.

(8) Prevention and control of diseases and insect pests: antagonistic bacteria were used for control. The antagonistic bacteria were a mixture of Trichoderma reesei and Bacillus subtilis at a weight ratio of 1:1. 10kg was applied per mu.

(9) Bud control: during the first ten days of June, the preparation for controlling bud growth was sprayed to restrain bud growth as much as possible.

(10) Grass cover: in the high temperature season in July, a layer of leaves and wheat bran can be spread on the surface to adjust the ground temperature and make Atractylodes macrocephala Koidz safely over the summer.

(11) harvesting and processing: in the year when Atractylodes macrocephala Koidz was planted, the suitable harvest time was when the stems and leaves of Atractylodes macrocephala Koidz began to wither. When harvesting, dig out the rhizome, cut off the stalk, and transport it back for processing. When drying, use high heat at the beginning, the temperature can be controlled between 95 ℃, drop the temperature to 65 ℃ when there is water vapor, turn it once in 2. 5 hours, take out the stifling pile and "sweat" for 8 days when the fibrous root is dry, then bake it to the whole dry, and rub off the residual stem and fibrous root.
