Abstract
The invention discloses a kind of methods that sodium acid carbonate is applied in the soil of highly acid tea place and reduces plumbi content of tea, sodium acid carbonate is applied in batches in the soil in the extremely strong acid tea place of pH value 3.5-4.5, improve pH value, reduction stationary state lead is because being acidified, the free content as Available Lead, Pb in Soil amount is absorbed to reduce tealeaves, mitigates pollution of the lead for tealeaves.This method is beneficial to quality and safety of tea.
Description
Technical field
The invention belongs to Tea Science fields, are related to and apply sodium acid carbonate in extremely strong acid tea garden soil, promote pH value, prevent
Reference state lead dissociates due to acidifying for Available Lead in soil, so as to reduce intake of the tea tree for lead, mitigates lead for tealeaves
Pollution.
Background technology
Lead is a harmful heavy metal species.Country road dust, highway automobile tail gas, tea finish machine's ash
All contain lead in dirt, be all the primary pollution source of tealeaves lead.Contain lead in soil, reference state lead is not absorbed by tea tree.But in acid
Drench with rain it is molten under, reference state lead can separate out, be converted into Available Lead, can be absorbed by tea root, and then be transported to tea free
In piece, brewed with boiling water, drink finished tea during lead be put into millet paste.This Situation of Lead Pollution is in the pole of pH3.5-4.5
It is become apparent in acid soil.If improving pH, reference state lead can be prevented to be converted into Available Lead, mitigate lead for tealeaves
Pollution.
The content of the invention
The object of the present invention is to provide a kind of methods that sodium acid carbonate is applied in the soil of highly acid tea place and reduces plumbi content of tea.
In the tea garden soil of extremely strong acidity, pH value is 3.5-4.5.In such sour environment, reference state lead is due to acidifying in soil
Separate out becomes Available Lead.Tea tree cannot absorb reference state lead, but can absorb Available Lead, therefore pole acid soil
The plumbi content of tea of middle output is significantly higher.
The September during June, autumn rain in plum rain season, soil moisture content increase, apply sodium acid carbonate respectively, can neutralize
Acidity promotes pH value.10-15cm ditches can be opened on the soil between tea clump, sodium acid carbonate is applied in ditch, applies per acre every time
30—50kg。
The present invention can prevent reference state lead to be converted into Available Lead by improving pH, mitigate pollution of the lead for tealeaves.
Specific embodiment
Embodiment
1 materials and methods
1.1 experimental field overviews
The tea place for selecting a piece of 10 mu of soil of area extremely acid in the emerging town in Zhejiang Province Songyang County on June 15th, 2014, divides equally
For 5 regions of A, B, C, D and E.10 soil samplings of checkerboard type in every region tea place, fetch earth 1kg per sampling point, and the depth that fetches earth is
10cm is uniformly mixed, and surveys the pH value per region tea place.1 bud, 2 leaf tender tip is picked in every region tea place simultaneously, detects lead content.
A-quadrant：September 15 days during June 15, autumn rain during plum rains, the soil between tea clump opens 10-15cm zanjons,
40kg sodium acid carbonates are applied respectively.
B area：September 15 days during June 15, autumn rain during plum rains, the soil between tea clump opens 10-15cm zanjons,
20kg sodium acid carbonates are applied respectively.
C regions：It on April 15th, 2014 ditches with method and applies sodium acid carbonate 50kg.
D regions：It on November 15th, 2014 ditches with method and applies sodium acid carbonate 50kg.
E regions：Sodium acid carbonate is not applied, as CK regions.
It repeats to apply Bicarbonate in 2014 with method within 2015.
On June 15th, 2016, with method in every region tea place 10 soil samplings of checkerboard type, survey soil pH value.Again from upper
5 region picking 1 bud, 1 leaf tea tips are stated, detect lead element content.
1.2 Tea Samples are analyzed
By Tea Samples in 80 DEG C of drying, crushing.Sample 1.0g is weighed, is placed in 30ml porcelain crucibles, crucible is placed on electric heating
Heating carbonizes sample on plate, and until sample carbonizes, smoke disperses, and sample moves into high-temperature electric resistance furnace.It is to slowly warm up to 500 ± 25
DEG C, constant temperature 2h, until sample is in canescence, cooling adds in 1:1HNO32mL is dissolved by heating, then cleaned with deionized water, is cleaned
Liquid enters in 25mL volumetric flasks, and constant volume is to be measured.Lead content inductively coupled plasma atomic emission spectrometer (ICP- in solution
OES) measure, model IRIS/AP, the production of power ＆ light company of the U.S..With national standard reference substance-tealeaves standard sample during measure
GBW 07605 (GSV-4) is used as quality control standard, to ensure the accuracy of determination data.
The ICP-OES Instrument measuring parameters of setting：Lead, the detection spectral line of emission of cadmium element be respectively 2203nm and
2265nm, detector C ID low band (＜ 265nm) time of integration are 15s, high band (＞ 265nm) time of integration 5s；Sample introduction is compacted
Dynamic revolution speed 100r/min；Sample introduction atomizer argon pressure is 193kPa；Secondary air amount is 1.0L/min；Radio-frequency generator work(
Rate is 1500w.It is repeated 4 times.
2 results and analysis
After table 1,2 years：CK regions pH value is declined, and tea tree tender tip lead content is increased by 5%, discloses in soil
Available Lead content increases, and tea tree absorbs more lead.
Other 4 Zoned applications sodium acid carbonate, pH value have certain amplitude promotion respectively, and corresponding thamnolia vermicularia tip lead content is reduced
11% -39%, i.e. the content of soil available lead is reduced, and results in the reduction of tea tip lead content, most apparent with a-quadrant；I.e. in plum
September during June in rainy season, autumn rain applies sodium acid carbonate in batches, and during trench digging is manured into soil, each dosage is left for 40kg per acre
It is right.
The increase and decrease of (2014) (2016) soil pH value and tea tip lead content afterwards before the application sodium acid carbonate of table 1
