Description
Technical field
The present invention relates to soil improvements and ecological restoration technical field, and in particular to a kind of tea garden soil acidification modifying agent and
It is applied.
Background technology
Tea tree is typically to get well sour crop, but the factors such as the metabolism of tea tree own growth, acquisition of tealeaves can accelerate soil again
Acidification, in addition a large amount of applications of nitrogenous fertilizer are also the key factor of aggravation tea garden soil acidification.Make although tea tree is typical happiness acid
Object, but its suitable growing environment is between soil pH section 4.5~6.0, the growth of tea plant when pH value is less than 4.0 or higher than 6.0
It will be suppressed.In addition, highly acid tea garden soil will increase the content of Aluminum in Tea, and excess of the aluminium in human body accumulates quilt
Think related with senile dementia with chronic neurological disorders.It is suitable to its it is therefore desirable to regulate and control to highly acid tea garden soil acidity
The yield and quality of tealeaves is improved in section.
At present liming be improvement acid soil more effectively and common method, but a large amount of or chronic administration lime
Soil hardening can not only be caused, and the addition of a large amount of calcium constituents can cause the antagonism to magnesium, potassium element, so as to cause soil
Calcium, potassium, three kinds of elements of magnesium dysequilibrium and lead to the underproduction.It is also possible to cause magnesium and aluminium in the excessive liming of acid soil
The co-precipitation of hydrated oxide reduces the Mg in the soil liquid2+Activity and plant availability.In addition, lime category mineral resources,
Long-term exploitation certainly will damage ecology.Especially for Tea Garden Ecosystem, it be easy to cause office in the actual production process
Portion excessively applies, and exceeds the proper limits in righting a wrong, in addition excess amount of Ca2+Absorption can reduce amino acid in tealeaves, water-soluble apparent extract, seriously affect
Tea leaf quality.
In consideration of it, can have a good improved effect to acidification or acid soil it is necessary to provide a kind of, chronic administration is not yet
The tea garden soil modifying agent that tea garden soil can be impacted.
Invention content
The purpose of the present invention is to provide a kind of good to tea garden soil acidification improved effect and chronic administration will not be to tea
The modifying agent that Orchard Soil impacts.
To reach above-mentioned technical purpose, technical scheme of the present invention provides a kind of tea garden soil modifying agent comprising as follows
The each component of parts by weight：12~25 parts of charcoal, 4~10 parts of egg shell, 1.5~3.7 parts of humic acid, hydroxycarboxylic acid chemical combination
0.2~2.3 part of object.
Compared with prior art, beneficial effects of the present invention include：In tea garden soil modifying agent in the technical program
Main component is charcoal, and charcoal itself is in alkalinity, and it not only has larger porosity and specific surface area, also contains tea
Set the mineral elements such as K, Na, Ca, Mg, the Si needed；Egg shell can not only provide albumen and calcium element for soil, consume in soil
Acid, moreover it is possible to provide good nutrition for soil；Contain more hydroxyl and carboxyl official in humic acid and hydroxycarboxylic acid compound
Can group, applied in acid soil, can in soil hydrogen ion and aluminium ion have stronger exchange capacity and suction-operated,
Meanwhile other in soil can also be complexed to the harmful heavy metal ion of crop in humus acid；Biomass and egg shell are porous
Structure, can load humic acid and hydroxycarboxylic acid compound, and these types of substance can increase according to certain proportioning compounding application
Improved effect of the strong modifying agent to acid soil.Meanwhile charcoal, egg shell, humic acid and hydroxyl carboxylic in the technical program
Acid compound is safe from harm to soil and tea tree, is suitble to chronic administration.
Specific implementation mode
Present embodiments provide a kind of tea garden soil modifying agent comprising each component of following parts by weight：Charcoal 12
~25 parts, 4~10 parts of egg shell, 1.5~3.7 parts of humic acid, 0.2~2.3 part of hydroxycarboxylic acid compound.
Charcoal：Be biomass material (such as：Sawdust, agricultural crop straw, grass or other Wastes of Crops) it is lacking completely
Oxygen or in the environment of the anoxic of part, pass through high temperature pyrolysis generate a kind of concrete dynamic modulus, high-specific surface area rich carbon product.Biology
There is the alkaline matter of certain content in charcoal, so in alkalinity；Meanwhile not only carbon content is high in charcoal, nitrogen, phosphorus, calcium, potassium and
The content of magnesium is also relatively abundanter, and these nutrient elements are also supplied with the nutrient needed for plant growth.
Egg shell：Calcium carbonate and protein are rich in egg shell, wherein also contain various trace elements, such as：Zinc, copper,
The elements such as manganese, iron, selenium, and the structure of eggshell is porous, and eggshell is added into soil, can not only maintain moisture, moreover it is possible to for flower
Grass provides nutrient.
Humic acid：Also known as humic acid, a kind of natural organic polymer compounds are the chief components of humus.It is rotten
Plant matter is the main organic principle in soil, peat, coal, many highland streams, rotten plant nutrition lake, seawater, dead by organic-biological
It is generated through biodegradation after dying.A humic acid not instead of single acid, one complicated to contain the functions such as carboxyl, phenolic hydroxyl group
The mixture of group.Humic acid cation exchange capacity is very big, is applied on acid soil, can in soil Na, Ca, Mg, Fe,
Al, Cl etc. have very strong exchange capacity and suction-operated, reduce the chloride in the soil liquid, sulfate concentration, reduce salt
Divide the harm to crop, the buffer capacity of soil can be enhanced.
Hydroxycarboxylic acid compound：Hydroxycarboxylic acid compound is tartaric acid, citric acid or tartaric acid and citric acid
Mixture.Hydroxycarboxylic acid compound contains hydroxyl and carboxyl simultaneously, is applied in acid soil, can be to the hydrogen ion in soil
There is stronger exchange capacity and suction-operated with aluminium ion.
The present embodiment additionally provides the preparation method of the tea garden soil modifying agent comprising following steps：
(1) following parts by weight are pressed to stock up：12~25 parts of charcoal, 4~10 parts of egg shell, 1.5~3.7 parts of humic acid,
