1. Land selection: sandy land with raw land or land reclamation, cool and ventilated, well drained and fertile.
2. Site preparation: After selecting the plot, 50 kg of compound fertilizer per acre, 50 kg of phosphate fertilizer, 15-20 cm deep, flat, mechanically laying 80 cm black thick mulch, film and film spacing 30~40 cm.
Matters needing attention: According to the topography of the terrain, it is necessary to ensure that the drainage is smooth and does not accumulate water, and the base fertilizer is applied to ensure sufficient fertility.
Preparation of seeds (seedlings)
1. Selection of seedlings: The fresh atractylodes tuber planted in the previous year is used as the seed, which requires strong and no pests and diseases, and has many bulbs and no roots.
2. Cut the seedlings: first cut the hairy roots, then cut according to the natural section of the tuber growth, cut into 3~4 cm, with 2~3 bud heads, weighing about 15~20 grams. Remember that the wound is not too big, too much.
Matters needing attention: try to choose no pests and diseases, more seeds of the bud head, the family of Atractylodes sinensis is better, the wild directly open.
3. Seedling disinfection: Cut the seedlings with 50% carbendazim or 70% methyl thiophanate 1000 times soak for 3 to 5 minutes, or spray disinfection directly. After the disinfected seedlings are dried, they can be planted.
Matters needing attention: seedlings must be disinfected, dried, and then put away for transplanting.
plant
1. Planting time: from November to April, transplanting on sunny days. Winter planting is better than spring planting. Planting is best before November until the soil is frozen.
2. Soil requirements: 墒 good, but not too wet, with a hand to hold the group to let go.
3. Plastic film planting method: Plant 3 rows on a wide 80 cm mulch with a row spacing of 20 cm and a plant spacing of 15 cm. Use a garden shovel to punch holes, 8 to 10 cm deep, put seedlings, bud heads up, section or roots down, cover soil 3-5 cm, remember to cover the soil too thick.
Field management
1. Weeding: After the planting of Atractylodes sinensis is about 4~5 months, after the seedlings are basically out, the weeds are associated with them, and weeding must be done in time. Weeding must be carried out on a sunny day. When weeding, loose soil, soil and clear ditch are carried out at the same time. Weeding should be carried out several times before entering the volts. After entering the volts, it will enter the high temperature and high humidity season, and it is not suitable for weeding. It is forbidden to weed in rainy days and when there is dew.
Enter the second year, the harvest year, and repeat the weeding work according to the growth situation.
2. Topdressing: timely topdressing to ensure fertility.
3. A few common diseases of Atractylodes:
Black spot: mainly harms the leaves, affecting the yield of Atractylodes, and the incidence is extremely high.
Chalk disease: mainly damages underground rhizomes, causing complete death of plants.
Root rot: mainly damages the rhizome, causing the plant to die completely.
4. Prevention and treatment methods Seedling disinfection and sterilization. Chemical control: From May to August, spray the fungicide once every 10~15 days. Commonly used fungicides are carbendazim, methyl thiophanate, and mancozeb. Root rot and chalk disease were found. The whole plant and surrounding soil were dug up, packed in plastic bags, and sent to places away from the planting base for destruction.
Harvest
1. Harvesting time: from November to March to April of the following year, harvesting on sunny days. Take care to avoid cutting the roots.
2. Harvesting method: clean the ground part, timely mining and processing.
3. Precautions: When drying and removing the soil, remember not to use fire.
