Cultivation methods and precautions of Atractylodes lancea

1. Maintenance methods

1. Temperature: It can withstand low temperatures. As long as the temperature is above five degrees, it can grow normally. It grows best when the temperature is twenty degrees. The maximum temperature should not exceed 35 degrees, otherwise it will grow slowly.

2. Watering: Water needs to be controlled after the seedlings emerge in order to promote root growth. If the weather is dry, the soil lacks moisture and needs manual watering. If the temperature exceeds 30 degrees, it needs to be watered every other day. The rainfall in the rainy season is relatively high, so good drainage is needed to prevent the roots from being waterlogged.

3. Fertilization: In addition to the base fertilizer mixed into the soil during planting, topdressing is also needed during the growing period. The time for topdressing is generally during the Great Heat Festival. Fertilizers such as bean cake and compound fertilizer can be used. When fertilizing, the fertilizer should not directly contact the roots of the plant to avoid fertilizer damage.

4. Light: It is not resistant to strong light, so the light should be mainly diffuse light, and the daily light time should be guaranteed to be four or five hours.

2. Breeding techniques

1. Reproduction: It can be propagated by division, and the time is after the Cold Dew Festival. After harvesting the plants, remove the medicinal tubers, then select disease-free and strong rhizomes, cut them into small pieces with a sterilized blade. Each small piece must have a bud on it, place them in a cool place to dry for half a day, start planting in holes with a row spacing of 25 cm, cover them with soil after sowing, and finally water them enough. Seedlings will emerge in about two weeks.

2. Bud removal: For plants that do not need to be kept for seeds, buds must be removed. Because the main part to be harvested is the rhizome rather than the fruit, in order to avoid unnecessary nutrient consumption, buds need to be removed to concentrate nutrients.

3. Problem Diagnosis

1. Pests: In summer, plants are more susceptible to aphids. Aphids mainly feed on the tender leaves of plants and spread diseases, which will affect the growth of plants. Therefore, treatment must be started as soon as aphids are found. When treating, you can use chemical agents or other insecticides to eliminate insects, or you can use 1:1:10 tobacco lime water for insect prevention treatment.

2. Pathology: The plant is more susceptible to root rot, which, as the name suggests, is a condition in which the roots rot. It is necessary to use thiophanate-methyl for irrigation treatment.

IV. Other issues

1. Edibility: It cannot be eaten directly, but it can be used as medicine.

2. Toxic: If Chinese herbal medicine is taken in excess, there will be some side effects. Therefore, you should follow your doctor's instructions and pay attention to the dosage.
