Seed price and planting method of Atractylodes macrocephala Koidz

Atractylodes macrocephala Koidz, also known as thistle, Yuzhu, Rhizoma Atractylodes, etc., is a perennial herb of Atractylodes macrocephala, which has the effect of dryness and dampness, turbid and analgesia, and has high cultivation value in Jiangsu, Zhejiang, Fujian, Jiangxi, Sichuan, Hubei and Hunan, and wild in Jiangxi, Hunan, Zhejiang, Sichuan and other places. Let's take a look at the seed price and planting method of Atractylodes macrocephala.

How much is the seed of Atractylodes macrocephala Koidz?

The price of Atractylodes macrocephala seed is about 3050 yuan per jin, but it varies according to variety, quality, origin and quantity. Atractylodes macrocephala Koidz likes cool climate, is afraid of high temperature and humidity environment, and does not have strict requirements on soil, but it is better to use micro-acid, alkali and light clay with good drainage and deep soil layer. The growth of overfertilized soil seedlings is too prosperous, which is easy to bolt and blossom in that year, which affects the medicinal quality. Seed propagation is mainly used in production.

Sowing method of Atractylodes macrocephala Koidz

1. Seed treatment: the seeds of Atractylodes macrocephala Koidz are required to be full and disease-free. Soak at room temperature for 24 hours from Qingming to Grain Rain, cover with wet cloth for 4-6 days, wash the seeds with clean water when the seeds are white, and then disinfect the seeds with 10% pentachloronitrobenzene solution.

2. Seedling bed arrangement: the Atractylodes macrocephala seedling bed is selected as the yellow mud slightly and sandy land where the sun is exposed to the east, the sun is protected from the west, and the climate is cool. 400 kg of organic fertilizer per mu is applied one month before sowing, and it is turned into the soil, leveling and raking the field to make a tall compartment 1.5 square meters wide.

3. Sowing method: Atractylodes macrocephala Koidz was sown from late March to early April, sowing 2-3 seeds per hole, then covered with fine loess, smoothed with bamboo broom, and covered with a layer of thatch to prevent the impact of Rain Water and soil consolidation. 3.5kg of seeds per mu.

4. Seedbed management: seedlings emerge one after another from 10 days to half a month after sowing Atractylodes macrocephala Koidz, weeding weeds frequently, weeding weak seedlings that are too dense in batches, and paying attention to diseases and insect pests at the same time. During drought, it is best to use bamboo branches or branches to shade, cover grass between rows, and water them evenly in the morning and evening to resist drought.

Planting method of Atractylodes macrocephala Koidz

1. Land selection and land preparation: Atractylodes macrocephala planting chooses sandy loam with fertile, loose, deep soil layer and good drainage at an interval of more than 4 years. After deep disinfection, 400 kg of organic fertilizer and 50 kg of calcium superphosphate per mu are applied to make a high box 2 meters wide and open the drainage ditch.

2. Timely transplanting: Atractylodes macrocephala Koidz was transplanted from December to early January of the following year. The holes were opened according to the row spacing of 18 × 21 cm. The basic seedlings per mu were controlled at 9000cm / mu. The holes should be planted directly, not horizontally. After planting, the surface of the hole was covered with fine soil about 5 cm thick.

3. Weeding in middle ploughing: Atractylodes macrocephala Koidz can only be pulled by hand in seedling stage, and the seedling frame can grow gradually after May, and the soil can be cultivated three times from May to August. In middle ploughing, shallow weeding should be mastered, those who rely on roots should be pulled out by hand, and the topsoil should be loosened immediately after rainstorm to reduce the humidity in the field.

4. Reasonable topdressing: after the emergence of Atractylodes macrocephala Koidz seedling fertilizer in April, 100 kg of organic compound fertilizer was mixed with water, 0.05 kg of urea was added per load, 200 kg of organic compound fertilizer was used per mu of strong seedling fertilizer in May, and 300 kg of organic compound fertilizer was used to double water after bud picking.

5. Removal of buds: the buds of Atractylodes macrocephala Koidz have been basically formed in mid-July. Buds other than remaining seeds should be removed in 2-3 batches within 25 days, and then sprayed with 2% superphosphate aqueous solution, if all buds without seeds are removed in order to increase yield.

Disease and insect control of Atractylodes macrocephala Koidz

1. Root rot

[damage] generally occurs in rainy spring and midsummer, rotting outward from the roots and gradually withering the upper parts.

[prevention and treatment] before planting, soak with 25% carbendazim wettable powder for 12 hours for 24 hours. If diseased plants are found, immediately remove the diseased plants and remove them to the nest soil to burn them. Disinfect the disease holes with quicklime. Spray Bordeaux solution at 1:1:2 after loosening the soil on a sunny day.

2. Blight

[harm] the root of the injured Atractylodes macrocephala appeared yellow-brown disease spot, then the disease spot expanded, and the diseased plant fell down and died.

Pay attention to drainage, watering with 1000 times of carbendazim wettable powder or transplanting mixture at the initial stage of the disease.

3. White silk disease

[harm] generally occurs in the high temperature season, and once it occurs and spreads very quickly, it can all die within a few days if it is not stopped in time, the roots rot from outside to inside, there are white hyphae or fimbriae in the rot, and the aboveground parts gradually wither and scorch.

[prevention and control] in rotation with Gramineae crops, strong seedlings were selected, the first 50% carbendazim was irrigated and disinfected with 1000 times of carbendazim, and 100g of taro humin was sprayed with 50 kg of water at the initial stage of the disease.

4. Dry blight

[damage] began to occur from late April to early May. After the seedlings were killed, a yellow-brown disease spot appeared at the base of the stem, and then the disease spot expanded, showing a dark brown dry shrinkage depression, and in severe cases, the diseased plant fell and died.

[prevention and control] loosen the soil in time after rain to prevent soil consolidation, and irrigate the diseased plants with 50% carbendazim 600 times or 50% methyl topiramate 1000 times at the initial stage of the disease.

5. Mosaic disease

The disease occurred more frequently in June. After the plant was damaged, the growth potential was weakened, the internodes shortened, the branches increased, the leaves shrunk, the edges were wavy, the leaves showed mosaic blister with yellow and green, the rhizome deformities were small, and the quality became worse.

[control] 2.5% deltamethrin or 20% quick kill tincture 3000 times solution can be used to kill aphids on Atractylodes macrocephala and surrounding weeds and reduce the source of poison.
