Description
Technical field
The invention belongs to soil conditioner technical fields, and in particular to a kind of Selenium in Soil element activator and preparation method thereof.
Background technology
Selenium is trace element necessary to a kind of humans and animals, has and removes free radical, anti-oxidant, anti-aging, anticancer, increasing
The biological characteristics such as strong immunity, antagonism heavy metal.Chinese Soclety of Nutrition recommends daily selenium intake for 50-250mg, but China
Only has 36mg or so at daily selenium intake for each person.Human body selenium source is human body mainly by dietary int ake, selenium-rich agricultural and sideline product
The effective way of selenium element is supplemented, therefore, technique of enriched selenium is the hot fields of scientists study exploitation.Selenium is general in the earth's crust
With metal sulfide association, exist in the form of rock.Selenium in rock cannot be absorbed by crops, but by weathering, erosion, object
The effect of reason, chemistry, microorganism etc., the selenium in rock can be converted into oxide, wash away into soil, form various forms,
Mainly include elemental selenium, Organic Selenium, selenite and selenate etc..Selenium in soil can be divided into according to valence state：Selenate, Asia
Selenate, elemental selenium and selenides；It can be divided by conjunction with kenel：Soluble state and weakly stable state, exchangeable species, carbonate combine
State, iron and manganese oxides reference state, organic matter reference state and residual form etc..The selenium of different valence state and different reference states, in soil
There is different migrations, conversion capability, also different to the validity of plant, soluble state, exchangeable species and carbonate combine in earth
The effect that state selenium absorbs crop is best.Effective selenium is the key factor of Se content in decision plant in soil, and not complete
Selenium.
The validity of selenium is influenced by the full selenium of soil, the soil texture, soil pH, Eh, organic matter etc..Wherein, soil is complete
Selenium reflect soil for selenium ability, fundamental role is played to the content of validity selenium.Weight is distributed with to Se form in soil pH
It influences, the solubility of the higher selenium of pH is bigger, and soluble state Se content is higher, is also more easily absorbed and used by plants, on the contrary in acidity
The low then plant absorption utilization rate of content of the low soluble state selenium of pH is also low on soil.The adsorbance of selenite in the soil, with
The raising of pH value.Soil pH is also to control the principal element converted between selenite and selenate, acid and neutral soil
Middle generally existing is selenite, and in good basic soil of ventilating, selenium mainly exists with selenic acid state.Since pH is very
Chemical form existing for selenium is determined in big degree, therefore affects the validity of selenium, and general acidity is stronger, solid to the absorption of selenium
Capability is also stronger, thus the selenium that can be absorbed and used by plants is also fewer, and as pH is increased, the validity of selenium accordingly carries therewith
It is high.
Chinese patent application document is " a kind of to promote the conditioner (patent No. that selenium activates in dryland soil containing selenium：
ZL201611084249.0 the conditioner that selenium activates in a kind of promotion dryland soil containing selenium) " is disclosed, it is raw materials used in conditioner
Percentage is：Seaweed skin 35%-45%, lime 17%-22%, magnesium hydroxide 10%-14%, humic acid fertilizer
20%-24%, peat soil 5%-8%, the sum of each raw material weight percentage are 100%.The invention has of low cost, preparation work
Skill is simple and practicable, can not only increase the economic benefit of crop, and the effect of safety and environmental protection, but there is the effects of selenium element activation
The problems such as bad.
Invention content

The invention has the advantages that：
As seen from the above table：(1) by the data of embodiment 1-3 and comparative example 5 as it can be seen that Selenium in Soil element made from embodiment 1-3
Activator is significantly better than comparison to the raising of the raising of tealeaves Se content and effective content of tea, soil pH and soil nutrient
Selenium in Soil element activator made from example 5 improves the Se content and effective content of tea of tealeaves, soil pH and soil nutrient carry
It is high；Simultaneously by the data of embodiment 1-3 as it can be seen that embodiment 1 is optimum embodiment.
(2) by embodiment 1 and the data of comparative example 1-4 as it can be seen that triacontanol, calcium magnesium phosphate, amino acid are preparing soil
Synergistic effect is played in selenium element activator, collaboration improves the properties of Selenium in Soil element activator；This is：
Triacontanol can improve the mineral nutrition of plant, promote plant growth, improve the resistance and disease resistance of plant, increase
Enzymatic activity in strong plant, to promote absorption of the plant to elements such as nitrogen, phosphorus, selenium.Amino acid is as a kind of root growth
Accelerating agent can be effectively facilitated tealeaves root growth and development, expand root absorbing area, be conducive to Nutrient Absorption and accumulate.Root system is
The most important absorption organ of crop, tealeaves mainly by root system from soil the nutrients such as uptake and accumulation selenium element, in soil
Using triacontanol, the more selenium elements of root system absorption and accumulation from soil can be promoted, to improve the selenium element content of tealeaves.
The selenium in phosphorus and soil in calcium magnesium phosphate exists in the form of oxo-anions, and chemical behavior is similar, phosphorus can by with
The adsorption site of selenium competition soil colloids impacts the environmental behaviour of selenium, when Phosphorus in Soil is more, due to phosphorus
The chemistry similar adsorption potential of acid group and selenite radical makes competitive Adsorption effect occupy leading position, and soil colloid is more
It is combined with phosphate radical, selenite radical is then activated and discharges, and so that the selenium element in soil is activated, this is greatlyd improve
The chemical availability of selenium in soil.The addition of calcium magnesium phosphate can improve soil acidity or alkalinity simultaneously, improve the pH value of soil, soil
Effective Se content and soil pH correlation, pH value is bigger, and soil available Se content is bigger, and the selenium element that tealeaves absorbs is got over
It is more.
Meanwhile it can be seen from table 1, table 2 in terms of tea leaf quality, water extraction is significantly raised, and moisture significantly drops
Low, polyphenol content is significantly raised, illustrates that the addition of selenium element activator is increasing the content of selenium while helping to improve tealeaves product
Matter.The increase of phosphorus content is related with phosphorus is contained in activator as can be seen from Table 2, but also promotes conversion and the profit of nitrogen simultaneously
With improving the content of the soil organism.
(3) by the data of comparative example 6-8 as it can be seen that triacontanol, calcium magnesium phosphate, amino acid weight ratio not at (1-3):
(2-5): when in (6-15) range, Selenium in Soil element activator obtained to the raising of tealeaves Se content and effective content of tea,
The numerical value of the raising numerical value and embodiment 1-3 of soil pH and soil nutrient is very different, the numerical value with the prior art (comparative example 5)
Quite.As reinforcement system, embodiment 1-3 passes through control and prepares Selenium in Soil element for triacontanol of the present invention, calcium magnesium phosphate, amino acid
When activator add triacontanol, calcium magnesium phosphate, amino acid weight ratio be (1-3): (2-5): (6-15), realize in reinforcing body
The mineral nutrition that plant can be improved in system using triacontanol, promotes plant growth；Amino acid promotes as a kind of root growth
Agent can be effectively facilitated tealeaves root growth and development, and calcium magnesium phosphate makes the features such as selenium element activates in soil so that triacontanol,
Calcium magnesium phosphate, Amino acid profile reinforcement system the present invention Selenium in Soil element activator in, make Selenium in Soil element activator to tea
Facilitation is played in the raising of the raising of leaf Se content and effective content of tea, soil pH and soil nutrient.
