What kind of tea do you drink? From a health point of view, when choosing a tea, you should choose according to your physique so that you can enjoy the taste of tea and adjust your health. So what kind of tea should people drink from ecstasy? Deficiency physical people usually have poor digestion, low appetite, chills and heat, slow pulse, and pale tongue, and it is best to drink black tea or dark tea.
Deficiency Constitution Drinking Black Tea
According to experts, black tea has the effect of warming the stomach and protecting the heart. Black tea has a wide variety of origins in China, and it is generally divided into three categories: time tea, black tea, and broken tea. The reason why black tea is so popular is because it has many advantages such as coloring dark brown oil, rich aroma and sweet taste, mellow mellow sweetness, bright red and bright yellow soup, and uniform and bright red leaves.
Black tea belongs to fully fermented tea. In the process of processing, tea polyphenols will oxidize to theaflavins and thearubigins, and most sugars will be hydrolyzed into soluble sugars, thus giving black teas a unique aroma and texture. Theaflavin is the most important functional component of black tea. A large number of medical studies have shown that drinking black tea helps regulate the levels of low-density lipoprotein and high-density lipoprotein in human arteries, and it is very good for reducing the incidence of cardiovascular diseases. Effect.
In addition, theaflavin can also be antioxidant, anti-cancer, prevent chronic inflammation and obesity. From the existing literature reports, black tea is more effective than other teas in preventing cardiovascular disease. From the point of view of traditional Chinese medicine, black tea is warm, and it has a warm stomach. Deficit people and the elderly are very suitable for drinking black tea. In addition, winter is also very suitable for drinking black tea, add some ginger to cold and warm up body effect is more significant.
Destitute body drink black tea
Black tea is also a kind of tea that is very suitable for people with defiture. Black tea is a unique type of tea in China. It has a long history of production and is rich in varieties such as Yunnan Pu'er tea, Hunan Fuzhuan tea, Guangxi Liubao tea, Hubei blue brick tea and Sichuan edge tea. Black tea belongs to post-fermented tea. During the process of fermentation, tea will undergo a series of chemical reactions under the action of microorganisms to generate many beneficial ingredients for the human body.
Although the active ingredients of various black teas such as Pu'er Tea and Fuzhuan Tea are different, they all have the effect of reducing fat and greasy, and the effect is very good. In addition, black tea contains a rich variety of minerals, and many types of minerals are higher than other teas. Black tea is warm, it helps to keep out the cold, and it is suitable for people who have a cold body.
Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated irrigation system
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
