What's the difference between phoenix narcissus and phoenix fir?
1, different distribution ranges
Phoenix narcissus originated in Fenghuang Mountain, Chaoan County, Guangdong Province, and was reportedly cultivated in the Southern Song Dynasty. There are more than 2000 trees over 200 years old. Mainly distributed in Guangdong Chaoan, Fengshun, Raoping, Jiaoling and Pingyuan. Since 1950s, it has been widely planted in Guangdong Province. Hainan, Guangxi, Hunan, Jiangxi, Zhejiang and other provinces introduced a small amount.
Chaozhou, located in the east of Guangdong Province, has a tropical maritime climate in South Asia, with a mild climate, an annual average temperature of 265,438 0.4℃, abundant rainfall, an annual average rainfall of 65,438 0.685.9 mm and evergreen seasons.
Chaozhou's main tea producing areas are characterized by high mountains, short sunshine, plenty of clouds and rain, no severe cold in winter and spring, and no heat in summer, which is very suitable for tea tree growth. There is no obvious dormancy period for tea tree growth, and tea can be produced all year round.
The soil types in Chaozhou are yellow soil, red soil, lateritic red soil and paddy soil. Yellow soil and red soil are mainly distributed above 400 meters above sea level, and the PH value is 4.5-6.5. The soil layer is deep and rich in organic matter (organic matter content is 3.8 1%-4.26%) and dozens of trace elements. These elements and substances undergo a series of chemical reactions such as tea metabolism and transpiration.
And then transported to bud leaves through tissues, thereby increasing nitrogen metabolites, which plays a vital role in the formation of aroma and lasting appeal of Fenghuang Dan Cong tea. Lateritic red soil and paddy soil have good hydrothermal conditions, deep soil maturity and high fertilizer efficiency, and the PH value is 5.5-6.5, which is suitable for the growth of tea trees, mainly distributed in low mountains and tea-producing areas.
Chaozhou has abundant rainfall, numerous rivers and streams, reasonable reservoir distribution, abundant water resources, diverse vegetation, beautiful scenery, high greening rate and forest coverage rate, strong green backing, effective soil and water conservation, climate regulation and air purification.
Therefore, in the dry season, except for plain tea gardens and tea seedlings, mountain tea gardens generally do not need shower irrigation. There are more than 3,000 single fir tea trees in Fenghuang Mountain, all of which are over 100 years old, with peculiar characters and excellent quality. Each tree is as tall as a banyan tree, with an annual output of 65,438+00 kilograms of dry tea.
2, the growth environment is different
Phoenix narcissus is a warm-loving plant. The optimum growth temperature is 20 ~ 25℃. Generally, seedlings are raised first and then planted in the open field. Not tolerant of waterlogging and drought, pay attention to drainage in rainy areas, and irrigate in time during drought.
Phoenix daffodils like temperature, but they are resistant to low temperature. Seeds germinate at 65438 05℃, and the fastest germination is at 30 ~ 35℃. The optimum temperature for growth and fruiting is 20 ~ 25℃. Night flowering is not resistant to high temperature. Blooming at night requires high light conditions. Under the condition of sufficient sunshine, there are few diseases, good growth, more fruits and high yield.
Phoenix narcissus is strict with water, neither early nor waterlogging. Higher air humidity is required during the result period. Night flowering is not barren, and soil rich in humus is suitable for water and fertilizer conservation. Nitrogen is the main nutrient needed, and appropriate application of phosphorus and potassium fertilizer can improve the yield and quality.
The optimum temperature of Abies phoenix is 20-25℃, and it grows slowly below 15℃, and stops growing below 8℃. It grows slowly above 30℃ and is easy to get sick. The suitable temperature for seed germination is 25-30℃, and it can germinate at 65438 03℃, but it is very slow. Germination at 30-35℃ is the fastest, but it is easy to cause overgrowth.
The flowering and fruiting period needs a higher temperature, and generally it is best to keep it at 22-25℃. The lowest temperature of root growth is 6℃, and the lowest temperature of root hair generation is 65438 02℃. The fertilized fruit can develop normally at night at 8-65438 00℃. The light intensity is moderate, and it is resistant to weak light, but insufficient light is easy to cause virtual length.
Plants with short photoperiod are beneficial to the growth of stems and leaves under long-day conditions, and bear fruit earlier under short-day conditions. Phoenix single fir likes humidity, is not drought-tolerant, and is prone to virus diseases under high temperature and drought conditions; But high temperature and high humidity are also easy to cause powdery mildew. The requirements for soil are not strict, sand, loam and clay can be cultivated, and loam with deep soil layer is easy to obtain high yield.
3. Different ingredients
Phoenix narcissus contains more than 450 organic chemical components and more than 40 inorganic mineral elements. Organic chemical components and inorganic mineral elements in tea contain many nutrients and medicinal components. Organic chemical components mainly include tea polyphenols, plant alkaloids, protein, amino acids, vitamins, pectin, organic acids, lipopolysaccharides, sugars, enzymes and pigments.
However, the content of tea polyphenols, catechins, various amino acids and other organic chemical components contained in Phoenix single fir is obviously higher than that of other teas. Inorganic mineral elements mainly include: potassium, calcium, magnesium, cobalt, iron, manganese, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine and so on. Rock tea contains more inorganic mineral elements than other teas, such as manganese, iron, fluorine, potassium and sodium.
4. Different effects
Phoenix narcissus has the effect of dissolving fat and losing weight. Because tannic acid, the main component of tea, is closely related to fat metabolism. Phoenix narcissus can reduce the cholesterol content in the blood.
Compared with Phoenix Narcissus, Phoenix Monofir can not only stimulate the activity of lipolytic enzymes in pancreas, reduce the absorption of sugar and fatty foods, but also accelerate the increase of body heat production, promote fat burning and reduce the accumulation of abdominal fat.
