In the present invention, humic acids, furfural dregs, ground phosphate rock, sodium alginate used are all in acidity, can improve soil after being manured into soil
The basicity of earth, and increase the crumb structure of soil.Wherein:
Ground phosphate rock is the industrial residue discharged during electrothermal way production yellow phosphorus, and after being manured into soil, the calcium oxide wherein contained can
Displace the sodium ion in soil, alleviate the salinity in soil；Sodium alginate has hydrophilic nmature, in weak glue after chance water,
While having water retaining function, sodium alginate can adsorb other adding ingredients, makes effect slow release, while improving soil,
Nutrition needed for plant growing in relatively long-term supplementary salt affected soil；Furfural dregs is the industrial residue after producing furfural, at present
Discard as industrial waste, pollute environment, but it contains humic acids, available nitrogen, available phosphorus, be the most rotten a kind of fertile money
Source；The macromolecular network structure that humic acids has can effectively reduce the sodium ion injury to crop, improves the degeneration-resistant of plant
Ability, can be effectively improved while providing moisture and nutrition for plant with water-retention, water conservation, slowly release nitrogenous fertilizer and phosphate fertilizer simultaneously
Soil environment, forms the environment being suitable for microbial reproduction, thus improves soil microorganism system further, improves soil knot
Structure.
Microorganism produces substantial amounts of polysaccharide in reproductive process, and these glucides are the binding agents forming soil granular,
Crumb structure makes loosing soil, cuts off soil capillary hole, increases non-capillary pore gap, improves the physical property of soil,
Making saline-alkali soil accelerate to drench salt action, it is suppressed that the accumulation of salt in the surface soil, meanwhile, the flora organic acid that metabolism produces in soil accelerates soil
The dissolving of middle insoluble salt, serves the effect of neutralization to surface soil alkalinity.
Maifanitum can be stabilized and increased, the physics function of balanced soil, and it contains ferrum, magnesium, calcium, potassium, phosphorus, manganese, copper
Deng the middle trace element needed for plant growing, there is the effect of the use of facilitation growth, minimizing chemical fertilizer, soil conditioner；
Vermiculitum contains multiple middle trace element, and the nutritional labeling of soil is had great regulation effect, the most also has ion exchange
Ability, the displacement of sodium to soil colloids absorption can be promoted during the reclamation of salinep-alkali soil.
Polyacrylamide has adsorption for sodium ion, can play the effect of salt reduction.Meanwhile, polyacrylamide has very
Strong flocculation, it can between molecule adsorption bridging, make the molecule condensed in soil flocculate into Semen Pisi sativi grain
The larger particles of size, increases permeability and the preservation capacity of water and fertility of soil.Meanwhile, the polar group granule on polyacrylamide is also
Many ions can be adsorbed, strengthen the nutrient preserving capability of soil.
The feces that feces of livestock and poultry, especially plant produce, amount pollutes greatly and easily to surrounding enviroment, but, it
It is the fertilizer comparing high-quality, its purity nitrogen, phosphorus (P2O5), potassium (K2O) content is higher, and itself is containing abundant nutrient, and comes
Source is wide, cheap and easy to get, fermented after poultry fertilizer can be that soil increases organic matter, enrich the nutrient content in soil, to soil
Earth plays improving effect effectively, thus effectively reduces and use the secondary injury that salt affected soil is caused by chemical fertilizer in a large number, and
Lumbricus feces has good permeability, aeration, drainage and high water-holding capacity, and its small graininess can also help to promote soil
Earth contacts as much as possible with air, with making soil no longer harden after mixing with soil and hard, additionally, wormcast is because there being the biggest table
Area so that many beneficial microbe existences, and there is the ability absorbing and keeping nutrient substance.
Straw stalks etc. include farmland straw that is former discarded and that burn, such as dry, stalk of fresh corn, straw, Caulis et Folium Oryzae, Brassica campestris L, Semen arachidis hypogaeae
Straw, the tree deciduous leaf such as leaves, pine needle, and wood flour, rice husk, Testa Tritici, etc. there is abundant fiber, fermented after can increase
Add the water penetration of soil, breathability and moisture retention, increase the content of organic matter of soil, reduce environmental pollution, beneficially environment and protect
Protecting, and bryophyte used is enriched due to its screen casing, the microstructure of many spaces, its superpower water absorbing capacity is up to own body weight
15-20 times and its evaporation capacity only have the 1/5 of water purification surface, and can secreting acidic material, soil capillary can be carried out meanwhile
Block, prevent salinity in subsoil water from rising.
Pyroligneous liquor be mainly composed of auximone, gibberellins, cytokinin (planting), abscisic acid, ethylene, organic
Acid system (phosphoric acid, carbonic acid, silicic acid etc.) hundreds of, yttrium: 12 kinds of potassium, sodium, magnesium, ferrum, manganese, calcium, chromium, zinc etc., also contain
There is multivitamin, there is the effect promoting plant growing, the improvement of saline-alkali soil can be applied to as plant growth substances, fertilizer
During.
Compared with prior art, the invention has the beneficial effects as follows:
The alkaline land modifying agent of the present invention be mainly composed of fermenting plant fiber, beneficial microbe colony, fermentation animal
Feces, and add in acid humic acids, furfural dregs, ground phosphate rock, sodium alginate and can soil Middle nutrition composition be risen supplementary
Vermiculitum, Maifanitum and the pyroligneous liquor of effect, these compositions spread fertilizer over the fields behind salt-soda soil, form a complete circulation nutrition and change
Good system.First in acid humic acids, furfural dregs, ground phosphate rock, sodium alginate, the high alkalinity of salt affected soil is neutralized, fall
Low alkalinity, utilizes the sodium ion that soil colloids is adsorbed by the ground phosphate rock of Vermiculitum and the calcic that ion can be promoted to exchange afterwards
Replace, polyacrylamide sodium ion adsorbed, effective salt reduction, humic acids, furfural dregs, fermented after plant fine
Dimension and animal wastes are originated as abundant organic matter and organic fertilizer, for salt-soda soil that itself exist in soil and of the present invention
The microbial bacterial agent supplemented in modifying agent provides a good growing environment, multiplying rapidly and to organic point of microorganism
The crumb structure of soil and permeable, breathability are improved again by solution, and these are beneficial to the life of plant on salt affected soil
Long, pyroligneous liquor provides growth hormone and nutrient substance as plant growing auxiliary agent for plant growing；The adsorbable nutrition of sodium alginate
Material and moisture, play nutritional labeling slow release and water conservation, the beneficial effect of fertilizer conservation.
In sum, chemical reaction-organic matter-microorganism-somatomedin reasonable combination is got up by the present invention, utilizes soda acid
Neutralize reaction to reduce surface soil alkalinity, utilize ion exchange displacement sodium ion salt reduction, utilize sodium alginate water conservation fertilizer conservation；By supplementing
Organic and organic fertilizer improves soil aggregate, solves soil compaction problem, and supplementary plant growing desired nutritional composition,
Soil environment needed for growth of microorganism is provided；The glucide produced by microbial growth is formed crumb structure and makes soil
Earth loosens, and improves the physical property of soil, suppresses the accumulation of salt in the surface soil；Needed for utilizing the supplementary plant growths such as pyroligneous liquor, Vermiculitum, Maifanitum
Multiple nutritional components and growth auxiliary agent, thus improve the physicochemical property of salt affected soil, it is achieved the benign cycle of alkaline land soil.
