High-yield Cultivation Techniques of Rhizoma Atractylodis

Atractylodes is a perennial herb belonging to Atractylodes of the Compositae family. The rhizome has the effects of dryness and dampness, resolving turbidity and relieving pain. there are many trade names, such as Rhizoma Atractylodes and Atractylodes (Rhizoma Atractylodes), but many trade names can be divided into two categories: northern Atractylodes produced in the north and southern Atractylodes produced in the south. Let's take a look at the high-yield planting techniques of Atractylodes.

Growth habits of Atractylodes macrocephala

Atractylodes lancea is widely cultivated in medicine gardens all over China and likes cool climate. it is often wild in sparse forests, bushes and grasses on shady slopes of low hills. barren mountains, slopes and thin land can also be planted, but the sandy loam soil with good drainage, low groundwater level and loose structure rich in humus grows best, avoiding flooding, and the roots are easy to rot after flooding, so low-lying waterlogged land is not suitable for planting.

Propagation methods of Atractylodes lancea

1. Ramet propagation: when the buds are about to germinate in the middle and late May, the old seedlings are dug up, the soil is removed, and the rhizome is cut into several small pieces, each with 1-3 buds, and then planted in the field.

2. Rhizome propagation: Atractylodes rhizome propagation combined with harvest to dig the rhizome, cut off the rhizome with bud, and use the rest as medicine. After the incision is dried, it is planted in a hole according to the row spacing of 20 × 20 cm, one piece in each hole and compacted with soil.

3. Seed propagation: Atractylodes macrocephala usually raises seedlings in late April, and the seedling bed chooses sunny land, which can be sown or sowed in strips, using 3 to 4 kilograms of seed per mu, covering grass after sowing, removing cover grass after seedling growth, and planting seedlings with a height of 10 centimeters.

Planting techniques of Atractylodes lancea

1. Land selection and land preparation: Atractylodes lancea planting chooses loam with deep soil layer, good drainage, loose and fertile, sunny loam, sandy loam or humus loam as bed, applying 2000 kg farm manure per mu, generally using large ridge and high bed technology.

2. Fixed seedlings: direct seeding seedlings of Atractylodes macrocephala with a height of 5 cm and 6 cm. When the height of seedlings was 10 cm and 15 cm, the seedlings were fixed according to plant spacing of 15 cm and row spacing of 25 cm. 2. 3 seedlings were planted in each hole, and the number of seedlings per mu was generally 12000-15000.

3. Intermediate ploughing and weeding: Atractylodes should weed frequently and loosen the soil properly at the seedling stage. After transplanting, intermediate ploughing and weeding should be carried out 3 or 4 times a year, usually once every two months, and topdressing can be carried out while cultivating the soil.

4. timely watering: Atractylodes should always keep the soil moist before and after emergence to facilitate seedling emergence and seedling growth, immediately watering seedlings after soil thawing in early spring, watering in time when the dry soil is dry, and generally no watering after growing up.

5. Reasonable topdressing: 2000 kg of rotten human and animal manure per mu was applied at seedling stage of Atractylodes lancea, 2500kg to 3000kg of manure from rotten acquaintances plus 15kg of superphosphate from June to July, and manure or compost was applied in October, and the soil was watered after application.

6. picking buds and leaving seeds: in the commercial field of Atractylodes lancea, the buds were removed in time at the budding stage, so that nutrients were concentrated for the growth of underground rhizomes. Leave the field to choose loose and fertile land, strong and disease-free planting, properly thinning flowers and buds, and cultivate excellent seeds and seedlings.

7. Timely harvest: Atractylodes can be harvested 3-4 years after sowing or 2-3 years after transplantation. after the aboveground stems and leaves dry in spring or autumn, dig up the roots on a sunny day, shake off the soil, remove the residual stems, dry or dry, and knock off the fibrous roots.

Disease and insect control of Rhizoma Atractylodes

1. Root rot

[harm] the disease occurred in May and June, resulting in root decay, the function of absorbing water and nutrients gradually weakened, and finally the whole plant died.

[prevention and treatment] pay attention to ditching and drainage, develop diseased plants immediately, use 1000 times of 50% wettable powder, or 1% lime water, or spray with 50% topiramate.

2. Aphids

[harm] to harm leaves and shoots, especially in spring and summer, it can be controlled by chemicals or 1:1:10 tobacco lime water.

[control] 1000 times of 50% fenitrothion emulsion, 3000 times of 50% aldicarb wettable powder, or 2.5% 3000 times of methomyl emulsion, or control with 1:1:10 tobacco lime water.

3. Ground tiger

[harm] the young larvae feed on cotyledons and tender leaves, while the middle-aged larvae feed on the tender stems near the soil surface, which makes the plants die.

[control] it can be irrigated with 80% dichlorvos or 50% phoxim with water, or 50% phoxim EC mixed with fine sand.
