The present invention with activated humic acid as main component, compound Chinese medicinal stone, zeolite, citric acid, trace element, chitin and
Nitrolim forms.
The humic acids improving effect to soil:
Soil is that earth land can the loose top layer of growing plant.Fertility is the fundamental characteristics of soil.Impact fertilizer
The soil Elemental characters of power is a lot, mainly has: the thickness of plough horizon;The quality of topsoil soils and structure: soil has
Machine matter content;The nutrient contents such as Soil Nitrogen, phosphorus, potassium;Soil acidity or alkalinity etc..In current domestic anthropogenic soil, fertility level is low, soil
Earth physicochemical character is poor, and the low productive soil that crop yield is the highest accounts for about 30%.The Elemental characters of these soil can be summarized
For: " drought, flood, salt, alkali, acid, plate, thin " several words.Transformation low productive soil realizes balanced increase production to agricultural, accelerates agricultural modernization
Significance.Improvement low productive soil measure in, a large amount of application of organic fertilizers material, increase the soil organism be important measures it
One.Coal humic acid has similar structure and character to the humic acids in the soil organism, uses peat, brown the most in a large number
The humic acid fertilizer of coal, weathered coal and manufacture thereof, practice have shown that, it is also possible to play significant soil improvement action.One) saline and alkaline
The improvement of soil: the main harm of saline-alkali soil is: soil salt content is too high;Harmful ion is (such as Na+, CI-, HCO3-, CO22-, Mg2
+ etc.) concentration is excessive;Surface soil alkalinity is too strong;Grogs high degree of dispersion, Soil structure is poor;Crop growth is suppressed.For a long time
Use humic acid substance in a large number, can gradually change the physicochemical character of saline-alkali soil.1, the formation of soil agreegate is promoted;2, fall
Low table soil salinity;3, soil exchange capacity is improved;4, the acid-base value of saline-alkali soil is reduced;Two) improvement of Baijiang soil: Baijiang soil master
Northeast Area of China to be distributed in.A podzolic horizon of one layer of about 5-10cm is had bottom this kind of soil plough horizon, this layer of soil water permeability difference,
Coherency is strong, and acidity is big, and Soil structure is bad, and biological activity is weak, and crop root is difficult to penetrate, and this causes Baijiang soil low yield
Main cause.Using the peat increase to the soil organism, the change of soil rotten phytic acid composition has a major impact, wherein main table
The absolute content of Humic acids and fulvic acids, all has and rises significantly now, and the process applying a large amount peat becomes apparent from.Peat pair
The improvement of Baijiang soil, improves physical behavior and the nutrient situation of soil, improves soil humus content, add soil
Alkali exchange capacity, creates suitable environmental condition for plant growth.Through the soil of improvement, the content of available N and P is steady
It is scheduled in the level of 5-15mg/100g soil;Water capacity is maintained between 40-50%;Capillary porosity reaches more than 50%, soil
Unit weight, at about 1.0g/cm3, substantially achieves the due physical and chemical index of stable high yield soil.Through the Baijiang soil of improvement, plantation
Semen Maydis and the yield of Semen sojae atricolor, ratio do not improves nearly about two of former output increased, and economic benefit is the most notable.Three) red soil
The improvement of soil: southern china each province tropical and subtropical zone, has large-area distribution of red soil.In this kind of soil due to
High temperature and rainy, decomposition of soil organic matter is fast, and nutriment in a fertilizer is easily with rain water runoff, thus the soil organism and nutrient-deficient.Due to rain
Water is many, and soil neutral and alkali composition major part is by leaching loss, and do not allow the acidic materials such as runny ferrum, aluminum relatively to build up, especially aluminum
Increase and cause red soil in acid or highly acid.The composition such as ferrum, aluminum is easy to P adsorption simultaneously, makes P availability drop
Low.Additionally, Soil structure is bad, excess moisture, grogs water suction is dispersed into pasty state;During arid, soil block becomes solid hard.Red soil
Feature can be attributed to " sour, lean, plate, dry " four words.Use humic acid substance main on the impact of red soil chemical property
Showing: soil organic matter content improves, available nutrient content increases, and base exchange capacity increases, the trend that acidity is reduced.
Soil environment protection function:
Improvement soil environmental condition.Use humic acids, too strong, the grogs height too high, alkaline of saliferous in soil can be changed and divide
Scattered, the physicochemical character of Soil structure difference, promotes the formation of soil agreegate so that it is become kilter, thus be root system of plant
Growth promoter creates good condition.
Humic acids can promote the formation of soil granular.Hydroxyl in humic acids, carboxyl function group calcium easily and in soil from
Son generation Hirschfeld-Klinger reaction, then the crumb structure of soil it is the formation of by the physiological action of root system of plant, so that the sky of soil
Porosity increases relatively, and permeability is more preferable, and beneficially crops absorb nutrient and normal growth.
Utilize the acidity of humic acids, with the alkalescence in saline-alkali soil, the pH value of the principle scalable soil of reaction occurs to neutralize, from
And reach to administer saline and alkaline effect.Humic acids color is deep, is conducive to the absorption to solar energy, when humic acids is made by microorganism
Releasing heat again with when decomposing, humic acids enough in soil can make ground temperature improve and fully play the effect of anti-cold spell in spring.
Preventing and treating heavy metal pollution of soil.Humic acids participates in soil intermediate ion exchange reaction, the heavy metal ion in soil
Absorption is fixing, prevents them from entering biological cycle;Energy stable soil structure, provides substrate and the energy for soil microbial activity,
Thus affect indirectly the mobility of heavy metal in soil ion.
Humic acids reacts with the complex in soil, plays heavy metal-passivated ion, prevents heavy metal ion
Enter the effect of families of plant in a large number.
The effect of citric acid:
Citric acid has preferable eluting effect to Cd and Cu in combined contamination soil, and the drip washing clearance of Pb is relative
The citric acid of relatively low .80mmol.L-1 is able to reach 90.4%, 82.5% and 38.6%. Fructus Citri Limoniae to the clearance of Cd, Cu, Pb
The heavy metal that acid drip washing is removed is main with exchangeable species, carbonate combined state and the form of iron and manganese oxides combined state in soil
Exist.
At present, according to the form toxic characteristic of heavy metal, the approach of restoration of soil polluted by heavy metal mainly has two big classes:
(1) change heavy metal existing forms in soil so that it is fixing, thus reduce its animal migration in the environment and biology can profit
The property used;(2) heavy metal in activating soil so that it is absorbed by plant thus be transferred out soil.In view of Heavy Metals is at soil
Importance in Heavy Metal Pollution Control, is carried out heavy metal copper, Cd fractionation in the topsoil of vegetable garden, new bridge mining area, Tongling herein
Measure, have studied condition of different pH, different citric acid concentration, differing needles iron mine concentration and citric acid mutual with goethitum simultaneously
Copper, each Variation Regularity of Morphological Characteristics of cadmium element in soil under action earth, provide certain science to depend on to administering for heavy metal pollution of soil
According to.The Main Conclusions drawn is as follows: in (1) original soil, copper, cadmium content are all considerably beyond local soil background, and copper is mainly with residual
Slag state is main, and character is more stable;Cadmium, based on exchangeable species, easily produces toxic action to organism and environment.(2) mineral acid
Main change Heavy Metals by acid dissolution, the carbonate combined state of copper and cadmium and combination under mineral acid effect
State is all proportionate with pH.(3) after interpolation variable concentrations citric acid, in soil, Cu each state changes of contents is the most little, at 3mmol/
During kg citric acid, soil residual form Cu content is the highest, the display passivation to Soil Copper.And Cd each state changes of contents all compares
Substantially, generally make to organically combine state and residual form converts to other tri-state.(4) mineral acid and citric acid effect are added
Time heavy metal copper in soil, the change of cadmium each state mainly affected by pH, and citric acid reduces this change by complexing.
(5) interpolation of goethitum makes bioavailable state copper content in soil reduce, and residual form copper content increases, and embodies Soil Copper
Passivation.Reduce the exchangeable species of cadmium simultaneously and organically combine state, and carbonate combined state cadmium and iron and manganese oxides knot
Closing state cadmium percentage ratio and be above original soil, residual form cadmium content all decreases than in original soil.(6) citric acid is mutual with goethitum
The composite colloid of goethitum-citric acid can be formed during effect, strengthen the absorption of heavy metal active ion, reduce heavy metal toxicity
The effect of zeolite:
