Growing environment
Atractylodes mostly grows in sparse birch forests, shrubbery grasslands, shrubs and forest grasses, and is a rare plant. Among them, Jiangsu is the main producing area of Atractylodes lancea, and it is said to be an authentic Atractylodes production area, which has been used for alleviation throughout the country.
Most of the soil is loose, fertile, and well-drenched dark brown or sandy loam. Northern Atractylodes is cold-resistant, cool, and well-lit, and has a large temperature difference between the night and day. Atractylodes lancea is a cool, gentle and humid climate with strong cold resistance and is afraid of strong light and high temperature.
3 Distribution range
Distribution of Heilongjiang, Liaoning, Jilin, Inner Mongolia, Hebei, Shanxi, Gansu, Shaanxi, Henan, Jiangsu, Zhejiang, Jiangxi, Anhui, Sichuan, Hunan, Hubei and other places. Wild hillside grasslands, understory, shrubs, and rock crevices. Herbs are widely cultivated throughout the country. North Korea and the Soviet Union also have distribution in the Far East. Model specimens were collected from Japan.
4 main categories
Plant race characteristics
1. Atractylodes (Southern Atractylodes lancea): Perennial herb, 30 to 70 cm high. The rhizomes are fat, knot-shaped, with fine roots on the section, brownish appearance, aroma, and red-brown oil spots on the section. Stems erect, cylindrical and longitudinally angular, unbranched or slightly branched on upper part. Leaves alternate, base leaves with stalk or sessile, often deciduous before anthesis, middle leaves elliptic-shaped, ca. 4 cm, width 1-1.5 cm, intact or 3--7-pinnately lobed, margin thorny Sawtooth, dark green above, slightly white powder below, small upper leaves, no cracks, no blunt. Inflorescences in autumn, heads in many heads, basal bracts with 2 layers and inflorescences of equal length, total sepals 6-8 layers, ciliate; bi***ual flowers, uni***ual flowers. The flowers are all tube-shaped, white; bifurcate hairy plumes, slightly shorter than the corolla; female flowers with 5 linear staminodes. Achenes cylindrical, yellow-white hairs.
2. Northern Atractylodes lancea: Similar to Atractylodes lancea, the main difference is that the leaves are usually sessile, the leaves are wide, ovate or narrowly ovate, generally pinnately 5-parted, the upper stem leaves 3 to 5-pinnately lobed or undivided. The flower head is slightly wider, and the total sepals are usually 5-6 layers, which bloom in summer and autumn.
3. Atractylodes lanceolata: This species differs from the above two main differences: the leaves have long petiole, the upper leaves 3, the lower leaves feathers 3-5 full cleft, lobes oblong, obovate or elliptic, base gradually narrow and deferred, There are flat or inwardly curved bristle serrations on the edges. Flowering from August to September, fruiting from September to October.
Ultrasonic Heat Meters
Ultrasonic Heat Meters(ultrasonic calorimeters) are kind of energy meters measuring the flow rate and heat exchange through the ultrasonic method. The ultrasonic heat meters get the heat consumption value through the temperature sensors. The ultrasonic heat meters are mechatronic product based on the microprocessor and high precision sensors. Comparing with the Water Meters, electornic meters and gas meters, the ultrasonic heat meters need much more complicated designs and higher technology demand. Ultrasonic heat meters is kind of high technology products with mechanism, electronics and information technology. At present, the ultrasonic heat meters are more often used in many industries,through ultrasonic heat metering,can accurate to do what you want.
Ultrasonic heat meters are consisting of flow rate sensor, temperature sensor and calculator, which has the advantages in high tense construction and easy installation. We adopt the quality ceramic transducers which guarantee the high accuracy and stability of the ultrasonic heat meters. The ultrasonic heat meters have the characteristics as following: non mechanical movement, non wear and tear, non influence from the bad quality water and low غير مجاز مي باشدt maintenance; horizontal or vertical installation; installed in inlet water tube or return water tube according to customers` request (should be chosen in advance); adding the RS485 according to customers` demand to reach the aim of remote meter reading in order to be centralized management.
