Modern planting techniques and pest control

Atractylodes chinensis is a kind of traditional Chinese medicine that can be used to treat abdominal distension, edema, athlete's foot, cold and cold, eye fainting, etc. It is a promising Chinese herbal medicine. Then how to plant atractylodes? Let's take a look at the main points of the modern planting techniques of Atractylodes!

1. Selection

Choose a full, mature Atractylodes chinense seed, do not need to do seed treatment, live broadcast.

2. Cultivation plot selection

Generally, atractylodes can be planted in the soil, but it is better to use well-drained, loose, humus-rich sandy loam.

3. Fertilizing the soil

Before planting, apply 2,500 kg of manure or ring fertilizer per mu, and 50 kg of NPK compound fertilizer. After the fertilizer is applied, it is turned 25 to 30 centimeters deep, and then flattened and made into a crucible with a width of 1.2 to 1.5 meters. The length is self-determined.

4. Seeding and seedling

Seeds can be used for live seeding, seedling transplanting, and rhizome breeding. Because of the small amount of Atractylodes seeds, it is expensive, so the method of seedling transplanting is generally adopted.

(1) Live broadcast: From the end of March to the beginning of April, the stripping method is adopted, and the ditch is 20~25 cm in row spacing, and the ditch is 2 cm deep. The seeds are evenly scattered into the ditch, and the soil can be covered after sowing. It is also possible to use a special planter for Chinese herbal medicines to adjust the width and depth, and to complete the ditching, sowing, covering soil and compaction work in one step. 2 kg per mu. Watering after sowing, the soil can be wet without watering.

(2) Seedling transplanting: The seedling plots are ploughed and simmered, and the stalks are 1.0 to 1.5 meters wide and 5 to 6 meters long. Seeded at a row spacing of 10 to 15 cm and a depth of 2 cm. Cover the soil and level it, pay attention to watering and keep the field moist. 5 to 6 kilograms per acre, can be transplanted 6 to 7 acres. In the second year after the broadcast, the roots were dug out and transplanted into the whole field.

(3) Rhizome propagation: in March-April or September-October, combined with harvesting, digging roots, shaking off the soil, cutting the roots into small pieces, leaving 2 to 3 buds per small piece, and then planting it In a good cultivation pot, the row spacing is 27-30 cm, the plant spacing is 15 cm, and the soil is watered after covering the soil. The amount of roots per acre is about 80 kg. After sowing water in spring, when the ground is slightly dry, the sealing agent pendimethalin can be sprayed, which can effectively prevent annual grass weeds and some broad-leaved weeds.

5. Field management

(1) Miao Ding Miao: No seedlings after seedling plots and transplanting fields, live seedlings. Atractylodes should not be thin, when the seedling height is 5-6 cm, it can be used once, so it is better to not crowd. If there is a shortage of seedlings, it should be made up in time.

(2) cultivating and weeding: After emergence of Atractylodes lancea L., whether it is transplanted or rooted, it is necessary to loosen the soil and weed it in time to promote the extension of the root system, which is conducive to the growth of Atractylodes sinensis. Chinese herbal medicine weeder can be used to loosen soil and weed. When the Atractylodes sinensis seedlings are 10 cm high, the special post-emergence herbicide "Caihua Caoqing" can be used to remove most weeds. If apricot has been sprayed with a closed drug before emergence, so that a special herbicide can be sprayed again, the whole growth period of Atractylodes can be protected from weeds, and it does not affect the growth of Atractylodes.

(3) Topdressing: In the seedling stage of Atractylodes lancea, 2,000 kilograms of light human and animal waste water per acre is applied, and 15 kilograms of calcium phosphate is applied in June-July. It can be topdressed by Chinese herbal medicine planter, and the soil can be directly covered after fertilization, which can increase fertilizer efficiency. Pay attention to watering after fertilization. Pay attention to drainage during the rainy season to prevent lodging and rotten roots.

(4) In addition to flower buds: whether it is live or seedling transplanting Atractylodes, in addition to seeding, the flower buds should be removed to concentrate nutrients on the roots and promote root growth. Flower bud inhibitors can also be sprayed to inhibit flowering.

(5) Measures to increase production: proper close planting; in the middle of September, the rhizome is swollen and the effect of increasing yield is obvious.

6. Pest control

(1) Root rot: The disease often occurs in the rainy season, causing root rot, and the ability of the plant to absorb water and nutrients gradually weakens, and finally the whole plant dies. Control method: In the rainy season, it is necessary to pay attention to ditch drainage. It is found that the diseased plant is immediately removed, and then sprayed with 50% of the antibacterial WP 1000 times or 50% of the thiophanate 800 times.

(2) Aphids: Aphids are mainly harmful to leaves and young shoots, and can be sprayed with 50% of the anti-mite emulsion 1000 times solution or 50% anti-Pu Wei WP 3000 times.

7. Harvesting

Seeds are sown, roots are harvested 3 years after sowing; roots are used for breeding, and harvested 2 years after planting. After the fall from autumn to spring, the excavation should be carried out before the emergence of the seedlings. After the leaves of Atractylodes sinensis are withered, the stems and leaves can be cut by a cutting machine, and then the roots can be ploughed by tractors or mined by large machinery. The whole process is mechanized, which saves time and labor, and the roots are intact and without damage. The average yield of fresh goods is 1200-1500 kg, and the output of dry goods is 340-420 kg.

The above is about the modern planting steps and techniques of pest control. The atractylodes can be used as medicine when it is fresh. It can also be used as a medicine after air drying, but it will be stored for a long time after drying. Therefore, if you want to keep it for a long time, it is recommended to dry it!
