Abstract
The invention discloses a method for reducing the aluminum content in tea trees and tea. A black-green jade is machined into powder which is then dispersed in a soil cultivation layer at the root of a tea tree. Aluminum is an element which ranks only second to silicon in the earth crust and is widely spread in clay, feldspar and mica minerals, and vegetables, grains and tea also contain aluminum. The growth and disease resistance capabilities of the tea tree can be influenced when aluminum is insufficient. The aluminum is also a harmful element in the tea and is 200-1000mg/kg in content. The water-soluble aluminum in boiling tea reaches 148-601mg/kg. The aluminum content in old leaves in the tea tree is higher than that of tender leaves. When the content of aluminum ingested from daily tea drinking is more than 1mg specified in WHO (World Health Organization), osteoporosis and senile dementia are easily caused. So far, no method for reducing aluminum in tea trees exists. According to the method disclosed by the invention, an ultrafine jade powder solution containing soluble silica is applied to the soil at the root of the tea tree, so that soluble -SiO groups with negative charges are combined with Al<+3> in soil to form Al2O.Si2 which has low solubility and is used for fixing silicon in the soil, and therefore the absorption to the aluminum in the tea tree is reduced. The content of aluminum in the black tea or green tea as a finished product which is produced by using the method is reduced by 50 percent compared with that of aluminum in the black tea or green tea as a finished product which is produced without using the method.
Description
technical field:
The invention belongs to tree plant cultivation field, specifically a kind of method reducing tea tree and Aluminum in Tea content.
Background technology
In tea tree, aluminium forms the exchangeability hydroxy Al ion with organic compound in the acid ground of pH4.2 ~ 4.96, is absorbed by tea root, and moves to the blade that evaporation is strong.Make aluminium increase with leaf age and increase, in Lao Ye, aluminium is higher than aluminium in tender leaf.Picked-up aluminium too much has suffers from the danger of senile dementia, and silicon can the absorption of antagonism aluminium, and in biological tissue, silicon main source is silicic acid, is weak acid, under physiological ph conditions with Al
+ 3and Fe
+ 3react.Silicon, aluminium have impact to auxiliary aminoacyl-4 hydroxylase activity.The present invention adds the jade powder liquid silicon containing silicic acid in tea tree composite nutrient-fluid, and its mesosilicic acid group (-SiO) can remove the inhibitory action of aluminium ion to enzyme sea property.Experiment shows, due to Al
+ 3and Fe
+ 3compete the binding site on auxiliary amino acid acyl-4 hydroxylase, make the activity decrease of enzyme, the combination of aluminium is removed, and silicic acid and aluminium effect generate the silicate of indissoluble, aluminium is fixed in soil and reduces the absorption of tea tree to aluminium, thus decrease the content of the aluminium in tealeaves.There is no the report of similar inventions method at present both at home and abroad.
summary of the invention:
The object of this invention is to provide a kind of method reducing tea tree and Aluminum in Tea content.
Technical solution of the present invention is as follows:
Reduce the method for tea tree and Aluminum in Tea content, its feature is as follows: be processed into powder with blackish green jade, and dispersion imposes on tea tree root plough horizon.
Described reduction tea tree and the method for Aluminum in Tea content, its feature is as follows: described blackish green beautiful consumption is that every mu of tea tree uses 10 ~ 200g.
Described reduction tea tree and the method for Aluminum in Tea content, its feature is as follows: described blackish green jade is processed into the superfines of 1 ~ 40 μm, with water boil dispersion in 1 ~ 10 minute, in milky white suspension, mix with containing selenium plant nutrition liquid, impose on tea tree root plough horizon.
Described reduction tea tree and the method for Aluminum in Tea content, its feature is as follows: described blackish green jade adopts leftover pieces.
The beautiful powder of the present invention can impose in tea soil layer in a variety of forms, but because every mu of consumption is less, so use after generally needing dispersion, directly can disperse to use with water, also can admix other auxiliary material such as sand directly to use, also can mix with other fertilizer or nutrient for plants to use in the lump after disperseing and all can reach application effect, reduce tea tree to the absorption of Aluminium in Soil, and then reduce the aluminium content of tealeaves.
By the blackish green jade powder being rich in silica and multiple beneficial trace element, be processed into the ultra-fine jade powder of 1 ~ 40 μm, boil into emulsion be mixed into root execute in composite nutrient-fluid tea tree root topsoil root fill with, the every mu of beautiful powder amount of use 10 ~ 200g.Black tea or Green Tea Processing are undertaken by enterprise's special process.Become to sample tea through ICP-AES(plasma emission spectrometry) quantitative assay, aluminium content should be contrast about 50%.
embodiment:
Reduce the method for tea tree and Aluminum in Tea content:
1) micro mist of 1 ~ 40 μm is processed into the blackish green beautiful waste that Hunan area produces.Be preferably 10-20 μm.
2) jade micro mist being added 50 ~ 200 times of water boils 1 ~ 10 minute is suspension emulsion.
3) siliceous jade liquid is mixed with tealeaves composite nutrient-fluid.
4) jade powder 10 ~ 200g is executed in tea tree plow layer by every mu of root.Be preferably 100-200 gram.
5) green tea, the black tea formulated by manufacturer are plucked, wither, knead, drying process tea-processing.
6) in finished product green tea, black tea, aluminium content is less than 500mg/kg.
Check experiment, same tea place more than totally 100 mus, are divided into test region and check plot, and test region increases employing the inventive method, and check plot traditionally manages and uses.
Inspect 10 groups respectively by random samples to the tealeaves of output, the content of experimental group Aluminum in Tea is 300 ~ 700 mg/kg; The content of control group Aluminum in Tea is generally 900 ~ 1900 mg/kg; It can thus be appreciated that the inventive method truly has significantly falls aluminium effect.
Claims (1)
1. reduce a method for tea tree and Aluminum in Tea content, it is characterized in that:
