Atractylodes macrocephala belongs to the perennial herb of Asteraceae and Atractylodes. It is mainly distributed in mountainous wetlands such as Sichuan, Yunnan and Guizhou in China. It has many medicinal functions such as diuresis and blood sugar lowering. It is mostly used for spleen deficiency, diarrhea, diarrhea, sputum and dizziness. And other symptoms of the disease, then Xiaobian said that the Chinese medicine Atractylodes sinensis ecologically suitable distribution area and suitable planting area, I hope to help everyone. (1) Ecologically appropriate distribution areas Atractylodes is a small genus of East Asia, distributed across the cold temperate zone and mid-temperate zone of China; warm temperate zone, north subtropical zone, central and subtropical zone, and also distributed in North Korea, Japan and Russia. There are 5 genus Atractylodes in China, and the distribution is Korean Atractylodes, Atractylodes, and Western Hubei Atractylodes. Atractylodes. And Guan Ao. Atractylodes macrocephala is an important medicine for tonifying spleen and replenishing qi. It is rare to see wild varieties. They are cultivated. The main products are cultivated in Zhejiang and Anhui, and also produced in Hunan, Hubei, Jiangxi and Fujian. The main factors affecting the quality of Atractylodes macrocephala L. were topographical factors and climatic factors. The highest growth altitude of atractylenolides was greater than 500m, the lowest growth elevation was less than 100m, and the highest growth gradient was 3.00°-4.99. °, the lowest is 0 ° ~ 0.99 °. The highest temperature in the warmest season is below 25 °C, the highest content of atractylenolides. The lowest average dry season in 26-27 °C is greater than 10 °C, the highest content of atractylenolides, the lowest in 0-5 °C; the most wet When the monthly precipitation is 220-230mm, the content of atractylenolides is the highest, and the lowest is 210-220mm. Therefore, it is necessary to select the hilly zone with high ecological factors and the most suitable conditions. The topography and climatic conditions suitable for Atractylodes cultivation are: elevation Above 200m, the slope is 3°-5′, the wettest monthly precipitation is 220-230mm, the average warmest season is below 25°C, and the average dry season is above 10°C. (2) Suitable planting areas It can be planted in many places across the country, including Anhui (Taihe, Jieshou, Ningguo, Qixian, Xuanzhou, etc.), Jiangsu (Suihong, Haimen, etc.), Zhejiang (Xinchang, Qixian, Panan, Dongyang, Tiantai, etc.) , Fujian, Jiangxi (Xiushui, Tonggu, Yifeng, etc.), Hunan (Hongjiang City, Longshan, Zhangpu, Longhui, Fuyang, Ningxiang, etc.), Hubei (Laifeng, Xuanen, Zhuxi, Daixi) Etc.), Sichuan (Baoxing), Guizhou and other places are planted. Atractylodes cool climate, cold resistance, damp heat, fear of drought, can withstand low temperatures around -10 °C, and temperatures above 30 °C are inhibited. When planting, choose a slope with a high slope and a slightly inclined slope. The soil layer is deep, loose and fertile, and well-drained sandy loam is suitable for continuous cropping. The predecessor is a grass crop, which cannot be rotated with crops such as peanuts, tobacco, rape, cabbage, tomato, rehmannia, aconite and white peony. (3) Suitable growth environment conditions for Atractylodes (1) Community environment Baizhu was born on hillsides and woodlands. The native vegetation type in the growing area is under the evergreen broad-leaved and deciduous mixed forest or deciduous broad-leaved forest in Zhongshan area. The altitude is above 800m, and the soil is yellow soil or yellow brown soil. (2) Temperature Atractylodes is cool, afraid of high temperature, high humidity and high heat, generally in the north subtropical humid monsoon climate. Seeds start to germinate at 15 °C, germination is faster at 25-30 °C, germination is slower above 35 °C, suitable temperature is 10-15 °C after germination, suitable temperature is 25-29 °C in late growth stage, and whitening is inhibited when temperature exceeds 30 °C Growth. In winter, it can withstand low temperatures of -10 °C. When the temperature is between 25 and 28 °C, it is beneficial to enlarge the roots and accumulate nutrients and increase the yield. (3) Moisture Atractylodes is dry, afraid of humidity, and is more drought-tolerant. When there is continuous rainy weather, if there is no drainage measures, it will easily lead to blight, chalk disease and root rot. Atractylodes cultivation requires soil water content of 30% to 50%. At the same time, the germination and seedling growth of Atractylodes macrocephala have strict requirements on water. The water requirement during this period is 3-4 times of the seed, less than 1 time or higher than 5 Double will reduce the germination rate. (4) Soil Soil selection of nursery land: neutral or slightly acid sandy loam, yellow loam, requiring a pH value of 5.5-7.5, a slope of less than 15 ° ~ 20 ° of the shady land or wasteland. Precautions for atractylodes cultivation: Atractylodes should not be used for continuous cropping. The land must be replanted after 5-10 years. The former is best for grasses. It is also necessary to know that Atractylodes can not be associated with peanuts, ginseng, cabbage, tobacco, rape, and aconite. Rotation of rehmannia, tomato, radish, white peony, and rehmannia. (5) Lighting Wild Atractylodes sinensis, so it generally grows under the forest, while the cultivated Atractylodes grows in plains or hilly areas. Therefore, it is necessary to make shading measures, especially in the summer. Sofa Sets Guangdong Widinlsa International Co.Ltd , https://www.widinlsamachine.com
