Atractylodes can also be called 淅 、, 杨桴, Wu Shu, 片术, 苍术, etc. It is mainly distributed in mountainous wetlands such as Sichuan, Yunnan, Guizhou, etc. It is used as a root stalk and has many medicinal functions. It is mainly used for spleen deficiency. Diarrhea notes, fetal movement and other symptoms, today Xiaobian talk about the biological characteristics of Chinese medicine Atractylodes and management points in different periods.

First, the biological characteristics of Chinese medicine Atractylodes

Atractylodes is propagated with seeds and the planting period is two years. Planting and planting in the first year, planting in the winter or the next spring planting, harvesting in autumn after planting, seeds can germinate above 15 °C, plants grow faster in March-April, and slower in June-July When the plants bloomed, they entered a dormant period in November. In the spring of the second year, the germination returned to green, and the growth accelerated in 3-5 months. It entered the flowering period from September to October and was strong from October to November. The two-year-old atractylodes have a lot of nutrients, more flowers, and the seeds are full, suitable for breeding and breeding, and the leaves can be harvested after the leaves are withered. Atractylodes can be roughly divided into five growth stages: seedling stage, wintering stage, emergence stage, rhizome growth stage, and flowering stage.

Second, the management points of different periods of Atractylodes

1. Seedling stage

Atractylodes macrophylla is mainly based on seed reproduction. After the first year of breeding, it is planted and transplanted in the second spring. The seedling stage can be roughly divided into four stages: emergence stage, seedling stage, jointing stage and rooting stage. Seedling period: from seed sowing to Qi Miao, at this stage, the seeds are swollen and germinated, and the topsoil is germinated until the cotyledons are unfolded, and the time is about 25-30 days. The seedling stage: from Qimiao to the stems of the plants, the leaves are elongated, with long leaves. Mainly, the number of leaves increased, the time was about 60 days; the joint bud stage: from the stem elongation of the plant to the top of the bud, the stem section is elongated, and a few plants are budded in the late July, the time is about 60 days; the rhizome enlargement period: About one month after the bud (below the end of August), the plant has the largest shoots and the highest dry matter accumulation. In late October, the roots and roots reached the maximum, and the time was about 60 days.

2. Wintering period

After the seedlings were excavated from mid-to-late October to late November, they were built into a plant for storage and wintering. In the south, the method of stratified sand is used. In the north, after digging the ditch in the shade, the plant is placed in the ditch for storage, and the transplanting is carried out in the spring of the second year. The wintering temperature should not be too high, and the temperature should be below 10 °C.

3. Seedling period

After the wintering of the plant, the transplanted to the field in the spring of the second year, the transplanting is completed in the south before the end of February, and the transplanting is completed in the north in April. After the planting, the temperature of the buds starts to sprout at about 15 °C, and enters the rapid growth period above 20 °C. At this time, more fertilizer is needed. Therefore, the base fertilizer should be applied before transplanting, and the cover should be covered with moisturizing and heat preservation to promote germination and seedlings. Growth.

4. Rhizome growth period

The rhizome growth can be divided into three stages: growth initiation period, growth growth period and late growth stage. The growth period starts from mid-May to early buds to mid-August, and the rhizome grows slowly. During this period, it is necessary to pay attention to the flower buds to weaken reproductive growth and promote vegetative growth. Increase the accumulation of nutrients in the rhizome; the vigorous growth period is after the flower buds are harvested in late August and the mid-October, the rhizome growth is gradually accelerated. At this stage, pay attention to the top dressing in the first ten days of August, and regularly watering to avoid long-term drought affecting the expansion of the rhizome.

5. Flowering and fruiting period

From mid-May to early August, the flower buds are growing and growing. From September to October, they enter the fruiting period. The external environment temperature, light, humidity and other conditions are suitable for flowering results and rhizome enlargement. For the planting, it is necessary to strengthen the conservation and advance the topdressing to avoid High temperature and high humidity cause diseases, and the diseased plants are removed in time.
