Proline Fermentation Broth used in the present invention selects Dangshan County Lv Yuan ecological fertilizer Co., Ltd oneself, our company to produce
Product, and patent applied for (number of patent application are as follows: ZL201810112581.6).Proline Fermentation Broth has with produced by the present invention
Machine acid is mixed and made into Compound-acid in proportion, sprays onto the organic fertilizer carrier to ferment, is uniformly mixed and obtains improveing saline and alkaline and disappear
Except the organic fertilizer of soil hardening.Under the premise of guaranteeing that Compound-acid and organic fertilizer carrier are sufficiently mixed absorption, added Compound-acid
More reclamation results are better, and practice test Compound-acid quality accounting 15%, organic fertilizer carrier quality accounting 85% will not be made
At the waste of Compound-acid, and Effect of improving soil is fine.
The present invention provide it is a kind of improve it is saline and alkaline and eliminate soil hardening organic fertilizer and preparation method thereof, have have as follows
Beneficial effect:
(1) organic acid by the invention mainly includes acetic acid, ethylene and wood tar, and acetic acid belongs to organic acid, increases salt
Alkali soil with organic matter content while can neutralize basicity in salt-soda soil, reduce the pH value of alkaline land soil.And it can benefit
With the solubilization of organic acid, the solubility of calcium sulfate, calcium carbonate in soil is improved, activates the calcium ion being cured in soil,
The calcium ion being activated largely replaces the sodium ion with soil colloid absorption, the sodium ion being displaced by ion exchange
Functional groups with negative valency lose biological effectiveness, no longer damage to crops grows, then with irrigation at the complex compound for being dissolved in water
Water flows into depth of soils or is directly absorbed and used by plants.Since cation is closed, sulfate ion and chloride ion are with filling
It irrigates water and largely enters arable layer hereinafter, no longer damage to crops grows；
Wood tar is a kind of hydrocarbon-containifirst, acids, the higher organic compound of phenols, be hydrocarbon, phenol and its homologue, alditol,
The complex mixture of acetic acid and other various products can also neutralize the alkalinity in soil in acidity, improve soil physical chemistry
Matter increases the content of the elements such as organic matter, potassium, nitrogen in salinized soil；And its there are also the effects of desinsection, improve the pest-resistant of plant
Evil ability；
(2) present invention includes proline, and proline is one of constituent of vegetable protein, is natural pest-resistant, expelling parasite object
Matter, the osmotic pressure in adjustable plant cytoplasm can also stablize structure of biological macromolecule, release ammonia poison to reduce cell acid
Property, the excessively high influence to plant cell water suction of salt-soda soil salinity is reduced, the redox function of cell can be also adjusted as energy sink
Can, it is the important degeneration-resistant substance of plant, grows plant preferably, also containing other amino acid to plant in proline Fermentation Broth
Growth plays a driving role.
(3) organic fertilizer carrier by the invention is one of the fermented livestock excrement dried, biogas residue, biomass carbon
Or several mixtures, fungi can be generated after fermentation, accelerate organic fertilizer nutrient decomposition and its and alkaline land soil combination speed
Degree increases soil fertility, is conducive to crops and absorbs, grows, and it makes soil particle is cementing to become stable crumb structure,
Increase the permeability of soil, eliminate soil hardening, enhance the ability of soil water-reataining fertilizer-keeping, improves soil environment.
In conclusion organic acid, proline, organic fertilizer carrier have potent advantageous combination effect, production can be greatly promoted
The comprehensive performance of product reduces the salinity and basicity of soil while increasing soil fertility, improve the physicochemical character of soil, increases soil
Earth crumb structure increases the permeability of soil, improves soil water-retaining, fertilizer conservation and permeability, making can be straight by plant in soil
The available nutrient for connecing absorption increases significantly, and eliminates soil hardening, improves plant anti-insect, anti-adversity ability, grows plant more preferably, ploughs
The integrated production capacity on ground gets a promotion.
