Atractylodes rhizome into medicine, for spleen medicine, bitter and bitter taste, dryness and dampness, turbid, analgesic effect. This species has many trade names, such as Atractylodes macrocephala and Atractylodes macrocephala, but many trade names can be divided into two categories, namely, Atractylodes macrocephala from the north and Atractylodes macrocephala from the south. 

Morphological characteristics. 

Perennial herbs. Rhizome procumbent or obliquely ascending, coarsely long or usually pimple-shaped, bearing most adventitious roots of equal or nearly equal length. 

Stems erect, 30 × 100 cm tall, solitary or a few stems fascicled, often purplish red below or below middle, unbranched or upper but rarely from lower part of branches, all stems sparsely arachnoid hairy or glabrous. 

Basal leaves shed at anthesis; Middle and lower stems and leaves 8-12 cm long, 5-8 cm wide, 3-5 (7-9) pinnatifid or half-lobed, base cuneate or broadly cuneate, few sessile, enlarged semi-clasping, or base gradually narrowed into petiole up to 3.5 cm long; Parietal lobe unequal or subequal to lateral lobe, circular, Obovate, oblique-ovoid, ovoid or ellipsoid, 1.5 × 4.5 cm wide; Lateral lobes 1-2 (3-4) pairs, elliptic, long elliptic or Obovate-long elliptic, 0.5 × 2 cm wide; sometimes middle and lower stems and leaves do not divide; Above the middle or only the upper stem and leaves are not divided, Obovate, Obovate-long elliptic or long-elliptic, sometimes 1 to 2 pairs of triangular teeth or spiny-toothed shallowly lobed at or near the base. Or all stems and leaves undivided, middle stems and leaves Obovate, long Obovate, oblanceolate or long oblanceolate, 2.2 to 9.5 cm long, 1.5 to 6 cm wide, base cuneate, tapering to 0.5 to 2.5 cm petiole, The base of the upper leaf sometimes has 1 to 2 pairs of triangular spines. All leaves hard, hard papery, synchromatic on both sides, green, hairless, margin or lobe margin needlelike ciliate or triangular or double prickly teeth. 

The head inflorescences are solitary at the top of the stem branches, but do not form a distinct inflorescence arrangement, and the plants have most or a few (2 to 5) heads. Involucral bracts campanulate, 1 × 1.5 cm in diam. Bracts needlelike pinnatifid or deeply divided. Involucral bracts 5-7 layers, imbricate, outermost and outer layer ovoid to ovoid-lanceolate, 3 × 6 mm long; middle long ovoid to long elliptic or long oval, 6 × 10 mm long; Inner layer linear long elliptic or linear, 11 to 12 mm long.

Habitat. 

China distributes Heilongjiang, Liaoning, Jilin, Inner Mongolia, Hebei, Shanxi, Gansu, Shaanxi, Henan, Jiangsu, Zhejiang, Jiangxi, Anhui, Sichuan, Hunan, Hubei and other places. Wild in hillside grasslands, forests, thickets and rock crevice. It is widely cultivated in pharmacies all over China. North Korea and the far East of the Soviet Union are also distributed. 

Growth habit. 

Like cool climate, wild in low mountain shady slope sparse forest edge, bushes and grass. The vitality is very strong, barren mountain, sloping land, thin land can also be planted, but the sandy loam with good drainage, low groundwater level, loose structure and rich humus grows best, avoid flooding, after flooding, the root is perishable, so low-lying stagnant land is not suitable to be planted. 

Reproduction mode. 

Ramet. 

When the buds were about to germinate in the middle and late May, the old seedlings were dug up by roots, the soil was removed, and the rhizomes were cut into small pieces, each with 1 to 3 buds, and then planted in the field. 

Root and stem. 

Combined with harvest, dig out the rhizome, cut off the rhizome with buds, the rest for medicine, after the incision to dry, according to the row distance of 20 cm × 20 cm hole planting, each hole planted one, covered with soil compaction. 

Seed. 

Atractylodes macrocephala planting. 

In late April, the seedling bed chose the sunny land as the best. Before sowing, the seedling bed should be ploughed again with base fertilizer, raked and leveled, and made into a border with a width of 1 meter for strip sowing or sowing. Strip sowing in the border horizontal trench, ditch distance of 20 to 25 cm, ditch depth of 3 cm, the seeds evenly scattered in the ditch, and then covered with soil. Sow seeds directly on the border and cover the soil with 2 to 3 centimeters of soil. Mu to plant 3 to 4 kg, after sowing should be covered with a layer of straw, often watering to maintain soil moisture, seedlings grow out to remove the cover grass. When the seedling height is about 3 cm, the seedling can be planted about 10 cm, and the row spacing is 15 cm × 30 cm. After planting, the soil is compacted and watered. It is easy to survive on rainy days or in the afternoon. 

Cultivation techniques. 

Soil preparation and fertilization: choose deep soil layer, good drainage, loose and fertile, sunny loam, sandy loam or humus loam as the bed. 2000 kg of farm manure per mu. The use of large ridge high bed technology, bed width 130 to 140 cm, length depending on the need, bed height 10 to 12 cm, bed spacing 30 cm. 

Field management: ploughing and weeding. Weeding and loosening soil should be used frequently at seedling stage, and attention should be paid to weeding and weeding after planting. If the weather is dry, timely irrigation, can also be combined with topdressing. 

Topdressing: generally, topdressing 3 times a year, combined with soil cultivation, to prevent lodging. The first topdressing was applied to clear dung water in May, about 1000 kg per mu, and the second time, human feces and urine were applied at the peak period of seedling growth in June, about 1250 kg per mu, or 5 kg ammonium sulfate fertilizer per mu. The third topdressing should be in August before flowering, per mu of human feces 1000 to 1500 kg, at the same time add the appropriate amount of plant ash and calcium superphosphate. 

Irrigation and drainage: in case of drought, we should water the soil in time and keep the soil moist. In the rainy season, we should pay attention to drainage and waterlogging prevention in order to avoid rotting roots and dead seedlings and reduce yield and quality. 

Bud removal: in the bud stage from July to August, Atractylodes macrocephala plants should be removed in time to facilitate the growth of the lower part of the ground. 

Harvesting and processing: Atractylodes macrocephala needs to grow for 2 years before it can be harvested. Atractylodes macrocephala can be dug in spring and autumn, but the quality of excavation is good before the seedling is unearthed from autumn to early spring of the following year. After the Atractylodes macrocephala was dug out, the stems, leaves and soil were removed, 50% dry fashion was put into the basket, some of the fibrous roots were knocked off, and the skin was dark brown. When 60% or 70% of the sun was dry, it was hit again to get rid of all the old skins. Sun dry when the last hit, so that the skin is yellowish brown, that is, into a commodity. With a large, solid quality, cross-section cinnabar points, strong aroma is good. Each mu can produce about 200 kg of dry medicinal materials. 

Pest control. 

The disease was root rot and occurred in May and June. 

Prevention and treatment methods: attention should be paid to ditching and drainage, the development of diseased plants should be pulled out immediately, 1000 times liquid or 1% lime water should be poured with 50% wettable powder, and 800 times liquid can be sprayed with 50% tobuzin. 

Aphids damage leaves and young shoots, especially in spring and summer, and tigers in small land are harmful to insect pests. 

Control methods: you can use chemicals, or 1:1:10 tobacco lime water control.
