Description
Technical field
The present invention relates to a kind of saline-alkali soil conditioner.
Background technology
According to the United Nations's incomplete statistics, there are about 1,000,000,000 hectares of all kinds of salinized soil in the whole world, and 1.2 × 10 are there are about every year5Ha is filled
Irrigate soil and lose productivity because of salinization of soil.Therefore, research saline-alkali soil modifying agent be to ensure that 1,800,000,000 mu of China arable land red lines not by
The important leverage of influence.
At present, substantial amounts of achievement in research and product are had in terms of the research and production of soil conditioner both at home and abroad.In salt
Stain soil conditioner study it is more have the single modifying agent such as zeolite, flyash, sludge, green manure, polyacrylamide, but it is deposited
In improved effect comprehensively or the problems such as have different degrees of negative effect.In order to which the improvement for further improving soil conditioner is imitated
Really, its negative effect is reduced, increasing researcher is by different modifying agent compounding applications, but the method for compounding application is still
The problem of being worth inquiring into, in addition with natural material (particularly agricultural wastes) for raw material development of new multifunction soil improver
The improvement for carrying out low productive soil is the focus of current soil conditioner research, but how to control the harmful substance of discarded object (such as weight
Metal, pathogenic microorganism) need further exploration.Therefore, the skin effect of patent utilization nano material of the present invention, small size are imitated
Answer, macro quanta tunnel effect reduces content of beary metal and kill soil sex pheromone in ardealite, improves the fertilizer of modifying agent
Effect.Meanwhile, solve calcium preparation in existing improving saline soil agent because particle is larger smaller with soil particle contact surface and
Ca in modifying agent2+Replace Na in soil colloid+The problems such as ability is poor.
The content of the invention

Rice catalyst 2 wt %.
The nano-photocatalyst is TiO2。
Each component effect is as follows in above-mentioned formula：
Ardealite：Containing substantial amounts of calcium sulfate and free acid, wherein free acid has the work of regulation salinization soil pH value
With its main function of calcium sulfate is to balance salinization soil salt ion ratio and is the Na in displacement soil+Ca is provided2+。
Boric acid：With supplement calacareous soil boron deficiency and promote salinization soil plant in carbohydrate synthesis with
Effect of transhipment.
Zinc sulfate：With Zn necessary to be provided for plant growth2+, remaining acid SO4 2-, be conducive to decomposing basic soil
Calcium salt, discharge Ca2+, while soil pH value is reduced, the effects such as reducing basicity.
Urea phosphate：The effects such as with salinization soil nitrogen and phosphorus element deficiency and regulation soil pH is supplemented.
Potassium fulvate：Containing a great number of elements K, multivitamin, trace element, mycoprotein, nucleic acid, surface-active substance and
Somatomedin（Bioactive substance）Deng.With antiacid alkali, it is anti-oxidant, have very strong sequestering power to bivalent cation, because
This can form organic chelated microelement with the metal ion such as Fe, Cu, Zn, Mn, Ca, plant can be promoted to the absorption of mineral matter and
Utilize.
Nano-photocatalyst：With skin effect, the Na in salinization soil can be promoted+With the Ca in ardealite2+It is fast
Speed exchanges and reduced effect of content of beary metal in ardealite, can doping vario-property.In addition, nano-photocatalyst has similar plant
The effect of thing growth regulator, promote the effect of plant growth.
The preparation technology of above-mentioned Nano saline alkali soil improvement agent, comprises the following steps,
1）The ardealite of formula ratio is ground into powder with pulverizer or ball mill, it is standby；
2）By step 1）The ardealite powder of gained and the nanocatalyst of formula ratio are fully mixed, and are in wave-length coverage
Irradiation accumulation 10-30 days under 190-400nm ultraviolet lights, often accumulation is stirred 1 time, stirred 2-5 times altogether for 3-5 days；
3）By step 2）The mixture of gained and the boric acid of formula ratio, zinc sulfate, urea phosphate, potassium fulvate are in room temperature condition
Under stir and evenly mix, you can.
The step 2）In, accumulated 7-15 days under 200-260nm ultraviolet lights, best results.
Beneficial effects of the present invention：
Nano saline alkali soil improvement agent of the present invention, wherein containing nano-photocatalyst, can be reduced using its photochemical properties
Content of beary metal in ardealite；Soil sex pheromone is killed using the sterilization idiocratic of nano material；In addition, utilizing nano material
Surfactant property, improve modifying agent in ion-exchange performance, improve modifying agent fertilizer efficiency.Meanwhile, solve existing salt marsh
Change the calcium preparation in soil conditioner because of the Ca in larger smaller with the soil particle contact surface and modifying agent of particle2+Replace soil
Na in colloid+The problems such as ability is poor.
Nano saline alkali soil improvement agent produced by the present invention be used for improving salinization soil, using the boric acid wherein contained,
The free acid that urea phosphate and ardealite contain in itself can reduce salinization soil pH；Using the calcium ion contained in ardealite with
And the potassium ion balanced soil salt ion in potassium fulvate, reduce harm of the salt ion to seed and seedling；Using boric acid and
The problem of zinc sulfate supplement salinization soil boron, zinc deficiency, promote the physiological metabolism of various gourd, fruit and vegetables and field crops；Profit
Plant root growth is stimulated with the humic acid in potassium fulvate, plant biological activity is excited, improves plant fixed nitrogen, phosphorus decomposing, activation
Potassium, improves chemical fertilizer utilization ratio.Results from pot experiment test shows：Salinization soil apply 200kg/ mus of the modifying agent, soil pH compared with
Compareing (CK) reduces 0.22-0.41 unit, and soil salt content, which relatively compares (CK), reduces by 12.5%, the average plant height of wheat compared with
Control increase 15cm, spike length averagely relatively control increase 2.72cm, yield relatively compares increase by 10.6%.The simulation examination of indoor soil-column leaching
Test and show：200kg/ mus of the modifying agent is applied in salinization soil, salt content relatively compares increase by 61%, leaching liquor in leaching liquor
Middle water-soluble sodium content relatively compares increase by 24%, and this explanation applies the modifying agent in salinization soil, and Soil Desalting effect is obvious.
