Description
Technical field
The present invention relates to white tea planting technology fields, and in particular to a kind of Cultivate administration method for improving white tea Se content.
Background technique
White tea is one of Chinese six big teas, and white tea has shape bud Bo complete, drapes over one's shoulders milli all over the body, milli is fragrant clear fresh, and soup look is yellow
It is green limpid, light time sweet quality characteristic of flavour.Belong to slight fermented tea, is the special treasure in China's teas.Because of its finished product
Tea is mostly bud head, completely drapes over one's shoulders pekoe, and such as silver is gained the name like snow.
White tea is the rarity in tealeaves, and drug effect performance is very fabulous.It is ground according to civil long-term drinking and practice and modern science
Study carefully confirmation, white tea has the wine that relieves the effect of alcohol, clearing heat and moistening lung, calming the liver benefit blood, eliminating inflammation and expelling toxin, decompression fat reducing, elimination fatigue and other effects, especially
For excessive drinking and smoking, greasy excessive, irascibility it is excessively prosperous caused by uncomfortable, digestive function the diseases such as hinder, it is unique, ethereality to have
Health-care effect.
Selenium element is trace mineral nutrient needed by human, and the selenium total content of human body itself is about 6~20mg.Chase after collection
In in emerald green ball and prostate, vas deferens, can with sperm rise excreting.It is required in human body constantly to be obtained from diet
The phosphorus of sufficient amount, many devices of balance of concentration, the physiological function of tissue have important protective effect and facilitation.When shortage
When, just easily lead to the decline of human body rabbit epidemic disease ability.In addition, studies have shown that threatening more than 40 kinds of diseases of mankind's health and life
Pass, such as cancer, the symptoms such as cardiovascular disease, hepatopathy, cataract, dirty disease, sugared bed, physiological system disease are all held with human body.
It is most studies have shown that the active absorption of Selenium By The Plants hydrochlorate is completed by sulfate transport of high-affinity,
Recent studies have shown that the absorption of the adjustable selenite of phosphate, active absorption mistake of phosphate cotransporter in selenite
It plays an important role in journey；The selenate of plant absorption is transferred to overground part from root quickly, and selenous acid is reduced into blade
Salt, and then organic selenides is converted into its hetero-organization；And selenite and its metabolite are mainly collected in root, seldom
It is transferred to overground part.The metabolism that plant is participated in containing selenoaminoacid and selenoprotein is converted into the selenium in plant.
Soil calculation of thermodynamics the result shows that, (pe+pH > 15) selenate is main shape on the aerobic soil of alkalinity
State, (7.5 < pe+pH < 15) selenous acid in acid and neutral mineral soil；Therefore, the high Selenium in Soil solubility of pH value is big,
Soluble state Se content increases, and is easy to be absorbed and used by plants, otherwise since pH value is low in acid soil, soluble state Se content
Low, the absorption rate of Selenium By The Plants also decreases.
Meanwhile multidirectional botany is studies have shown that selenium is by replacing the sulphur atom in sulfur-containing amino acid to enter protein
, and then be absorbed by plants；In absorption and absorption process keen competition occurs for both elements, and sulfate passes through Competition
Influence the absorption of Selenium By The Plants hydrochlorate.
