Description
Technical field
The invention belongs to afforest field, it is related specifically to a kind of saline soil for concrete for plant growth and user
Method.
Background technique
Common celluar concrete is using cement, additive and large-particle-size aggregate (26 ~ 31.5mm) by stirring preparation at present
It forms, can generate 20 ~ 25% calcium hydroxide after hardening, the strong alkaline substances such as high alkalinity hydrated calcium silicate gel, substance of this kind is attached
In aggregate surface so that celluar concrete hole is typical alkaline environment, the root system at plant growth initial stage, plant can be given birth to
Long, in the later period, with the development of time, the alkaline matter in hardening of cement body surface face is cumulative, so that porous plantation concrete
Plant growth be greatly affected.The celluar concrete being prepared simultaneously is planted in the soil only in surface mulching soil
Plant, moisture in hole, fertilizer efficiency shortage and except alkali not enough thoroughly, will affect the final effect of porous plantation concrete
Fruit.
Summary of the invention
To solve the above-mentioned problems, the influence the object of the present invention is to provide a kind of elimination alkaline matter to plant growth,
Be retained effect and destructive effect makes the Water-saving effect of concrete for plant growth more preferably excellent simultaneously, fertility it is more preferably lasting for planting life
The saline soil and application method of concrete.
The technical solution of the present invention is as follows: a kind of saline soil for concrete for plant growth, the saline soil it is each
The mass percent of component are as follows: ammonium hydrogen carbonate 5 ~ 14%, humus 55 ~ 75%, organic matter 15 ~ 20%, sodium alginate 5 ~ 11%.
Further, the weight fraction ratio of each component of the humus are as follows: 20 ~ 25 parts of grass meal of mixing, sawdust 15 ~ 20
Part, 25 ~ 35 parts of diatomite, 15 ~ 20 parts of hay bacillus.
Further, the organic matter is methylcellulose.
It is a further object of the present invention to provide the method for preparing above-mentioned saline soil, this method specifically includes following step
It is rapid:
Ingredient: ammonium hydrogen carbonate, humus, organic matter and sodium alginate are weighed respectively according to design ingredient, is ground to 30-50
Mesh；
Mixing: the powder that step 1 is prepared is added sequentially in forced action type batch mixer, under ultrasonic wave effect, temperature
For degree at 1-2 DEG C, revolving speed is that 100-150 turns/min, mixing 10-15 minute, is mixed uniformly to get arriving saline soil.
The application method of saline soil is prepared in a kind of above method, specifically includes following steps；Firstly, making
When spraying concrete for plant growth, every 1000kg soil adds 50kg saline soil, together with substrate, vegetable seeds integration after stirring
Injection forms top soil to slope surface；
Secondly, being laid with the porous plantation concrete prepared in slope surface, after laying, saline soil is sown in more
Concrete surface is planted in hole, and thickness 5cm-8cm, surface layer watering, with seeping under water flow, saline and alkaline modified material will be filled in hole
Portion enables its saline and alkaline modification power to play.
The beneficial effects of the present invention are: the present invention on the basis of preparing concrete for plant growth using conventional cement base, uses
A kind of saline soil, by being added in the filling of celluar concrete hole, and injection concrete for plant growth stirring, thus by saline and alkaline
The carbonization effects of modifying agent remove alkali effect, are retained effect and destructive effect, are carbonized to the concrete for plant growth prepared,
Except alkali, water conservation and decomposition, the calcium hydroxide and carbon dioxide that cement concrete surface is generated, sulfate radical occur anti-
Answer, or react with ackd salt, in and while calcium hydroxide, slurry interface becomes more closely knit, thus obtain through
The porous concrete structure except alkali process is crossed, influence of the alkaline matter to plant growth is eliminated, while being retained effect and decomposing effect
The Water-saving effect of concrete for plant growth should be made more preferably excellent, fertility is more preferably lasting.It will be this raw mixed using the plant after saline and alkaline improvement
Xtah Crude Clay structure is used for the protection in river, massif, slope of highway, more the growth of suitable for plant and is conducive to restoration of the ecosystem.
