Cultivation Techniques of Rhizoma Atractylodis

Land selection and land preparation: Atractylodes lancea should be planted in loose and fertile sandy soil with good drainage and irrigation. Base fertilizer: sufficient mature farm manure is applied and can be sown after planting. Reproduction method: it can be propagated by strip sowing or sowing. Fixed seedlings: 2-3 strong seedlings were retained in each hole. Moisture: keep the soil moist before emergence and do not need watering after growth. Topdressing: from June to July, rotten farm manure was applied with calcium superphosphate, and furrow compost could be applied in October.

1. Sowing methods of Atractylodes lancea

1. Land selection and preparation

Atractylodes lanceolata should be selected in sandy loam with good drainage and irrigation conditions, flat terrain, fertile and loose sandy loam as seedling land, and planting field should be selected in sunny barren mountain slope. the soil requires good drainage, deep soil, fertile, loose sandy loam or humus, so it is not suitable to be planted in low-lying and waterlogged land.

2. Base fertilizer

After selecting the nursery land, about 3000-4000 kg of rotten farm manure can be applied per mu, and then deeply ploughed about 20-25cm, leveled and raked fine, the dry zone can be used as a flat border, and the rainy area can be used as a high border with a width of 1.2m-1.4m, and the length can be determined according to the specific topography.

3. Methods of reproduction

It is generally propagated by strip sowing or sowing from the end of March to the beginning of April.

(1) Article broadcast

Straighten up the border surface in advance, and then open the ditch horizontally according to the row spacing of about 15-20cm, and the ditch depth is about 2cm. Seed is applied in the ditch, soil compaction and watering. In order to keep the border surface moist, a layer of grass can be covered.

(2) sowing

Make the bed in advance, then sow seeds on the border, cover a thin layer of soil, and cover a layer of grass after sowing, the sowing amount per mu is about 3-4 kg.

II. Planting methods of Atractylodes lancea

1. The seedlings are fixed

Direct seeding of Atractylodes lanceolata and other seedlings can start when they grow to 5-6cm, and when they reach 15-20cm, they can be fixed according to the row spacing 25cm. Hole sowing can retain 2-3 strong seedlings per hole, and the number of seedlings per mu is 1.2-15000.

2. Ploughing and weeding

During the seedling period, shallow soil loosening should be carried out regularly to remove weeds. After transplanting, weeding needs to be ploughed and weeded about 3-4 times a year, once every 60 days, which can be carried out together with soil cultivation and fertilization.

3. Moisture

Be sure to keep the soil moist at any time before emergence, which is conducive to promoting seedling emergence, thus speeding up the growth of seedlings. When the soil is thawed in early spring, the seedlings should be watered immediately, and the dry weather should be watered in time. After growing up, there is no need to water.

4. Fertilization

During the seedling period, about 2000 kg of rotten farm manure can be applied per mu, and from June to July, it is mainly rotten farm manure, about 2500-3000 kg per mu, with about 15 kg of superphosphate. In October, the mature compost can be applied by ditch application, and then the soil can be watered.

5. prevention and control of diseases and insect pests

The main pests of Atractylodes lanceolata are aphids. If pests are found, the dead branches and leaves should be removed in time, buried or burned, and then sprayed with 1500-2000 times of dimethoate EC or 1000-2000 times of fenitrothion 1000-2000 times, once a week, several times in a row.
