Planting technique of Atractylodes macrocephala Koidz

Baishu must be familiar to many people. It is the most common red medicinal material in traditional Chinese medicine. It is distributed in many places in China at present. White atractylodes rhizome is very popular in the market at present, so many people have the idea of wanting to grow it. Then understanding its planting time and technology is a necessary prerequisite.

Cultivation techniques of atractylodes macrocephala

1. Clean up the seedbed. The largehead atractylodes rhizome is turned over one month before sowing, covered with weeds with a thickness of 30 cm, burned and disinfected to prevent diseases and insect pests from occurring, and grass ashes are turned into the soil after burning. If the soil is not burned, it can be turned up in the winter of the first year to make the soil fully weathered by freezing. After treatment, the land is made into a bed 100-130 cm wide and about 2 cm high. The bed surface is curved, the middle is high, and the four sides are low. 150 - 225 loads of human excrement are applied per hectare as base fertilizer.

2. Sowing. In arid areas, it is advisable to soak seeds in warm water for 24 hours, pick them up and mix them with sand and sow them into the field. If there are irrigation conditions, seeds may not be soaked. Sowing method points broadcast and drill two kinds. Sowing 150 - 112.5 kg seeds per hectare, planting 300 - 450 kg seeds per hectare, generally planting about 140-150 seeds per 0.5 kg. Drill 60~75 kg/ha, row spacing 16 cm, sowing width 6~10 cm, shallow furrow. About 3~5 cm deep, the bottom of the ditch should be flat, so that the emergence is consistent. Cover soil can be fumigated to cover 3 cm, 1 hectare seedling field can provide 150 hectares of land, soil should maintain sufficient temperature before emergence, or cover Artemisia grass or manure to avoid soil hardening (Beijing generally irrigates 2~3 times of emergence) The latter method is commonly used and easy to manage.

White atractylodes planting time

The sowing time of atractylodes macrocephala is generally from late March to early April every year.

Field management of atractylodes macrocephala

1. Timely thinning: thinning seedlings according to plant spacing of 4~6 cm after emergence of atractylodes macrocephala seedlings. If the weather is dry, weeding can be carried out among plants to reduce water evaporation. If conditions permit, watering can be carried out in the morning and evening to resist drought. If bolting is found in the later stage of growth, it should be removed in time.

2. Intertillage and weeding: There are many weeds in the field when the seedlings of atractylodes macrocephala are unearthed until May. Intertillage and weeding should be frequent. The first few times of intertillage can be deeper. After that, shallow hoe should be carried out. After mid-May, intertillage is generally no longer carried out. If there are weeds among plants, they can be pulled out by hand.

3. Reasonable fertilization: top dressing can be applied once before and after budding of atractylodes macrocephala, urea 20kg and compound fertilizer 30kg shall be applied in furrows per mu, soil shall be covered and watered after application, and top dressing can be applied once a week after bud picking.

4, irrigation and drainage: white atractylodes rhizome growth period needs sufficient water, especially the rhizome expansion period needs more water, in case of drought should be timely watering irrigation, such as water after rain should be timely drainage.

5. Removing flower buds: Generally, the plants begin to bud in the middle of June, and the buds are removed in batches from bud to flower in the first and middle of July, which is conducive to improving the yield and quality of Rhizoma Atractylodis Macrocephalae.

6. Covering grass over summer: White atractylodes rhizome is afraid of high temperature, so in July high temperature season, a layer of leaves, wheat bran, etc. can be scattered on the surface as mulch to adjust the ground temperature and make white atractylodes rhizome safe over summer.

Pest control of white atractylodes rhizome

1, disease early damage control disease has white silk disease, with 50% of the bacteria special 1000 times solution after soaking seeds planted, and sprinkle lime around the plant disinfection. Or irrigate the disease area with 50% methyl thiophanate 1000 times solution.

2. Rhizoctonia solani can be irrigated with 1000 times solution of 505 carbendazim. Iron leaf disease occurs from June to August, spraying 1:1:100 Bordeaux mixture or 50% thiophanate-methyl or carbendazim 1000 times solution.

3, rust can spray 25% triadimefon 1000 times solution.

4. Root rot was sprayed with 50% carbendazim 500 times solution and 50% thiophanate-methyl 100 times solution or 50% tuijunte 800 times solution.

5. In addition, there are sclerotinia, root knot early disease, mosaic disease, dodder and other damages. Early damage includes white atractylodes seed early, white atractylodes rhizome long tube aphid, red spider, beetle, cutworm and so on.

When planting white atractylodes rhizome, it is generally best to choose the most suitable spring every year. Then do a good job of site selection, and then carry out sowing. At the end of planting, strengthen its field management. White atractylodes is also vulnerable to insect attacks, so pest control should also be done in place.
