Description
Technical field
The present invention relates to a kind of selenium-enriched fertilizer, and in particular to a kind of nanometer selenium liquid manure solution and preparation method thereof.
Background technology
Selenium is the essential trace elements of the human body, is the activated centre of a variety of enzymes in human body, played in life resist disease,
Slow down aging, the effect of enhancing immune function.Selenium has protect liver, anticancer, protection is cardiovascular, adjusts hormone secretion, an antagonism huge sum of money
Many biological effects such as category, chemoradiation therapy, treatment cataract, the superfluous free radical of removing.Selenium product is in health food and medicine
Occupy critical role in product.
Selenium is not only beneficial to human body, and selenium is also a kind of beneficial element needed for plant growth, and selenium can stimulate the growth of plant
Root activity is sprouted and improved in development, seed, is promoted absorption and the plant metabolism of nutrition, is improved photosynthesis and chlorophyll
Content, strengthens plant biological antioxidation and the resistance to environment-stress, improves the disease-resistant anti-adversity ability of crops, and have
The effect of antagonism heavy metal.Using the selenium content of agricultural product can be significantly improved after selenium fertilizer, so as to greatly improve commodity value.It is existing
Selenium fertilizer in technology is mostly solid matter, is typically mixed with sodium selenite with organic matters such as animal wastes and/or plant defoliation
Compost maturity forms afterwards, or the organic selenium fertilizer prepared by modern biotechnology is directly added shape after auxiliary agent and water
Into selenium-rich liquid manure.Both the above method is disadvantageous in that：Selenium element does not have effective absorption carrier in existing fertilizer,
On the one hand there is no slow release effect, selenium concentration is higher when just applying, and plant suction speed is limited, after on the other hand applying, in rainwater
And be easy to run off or fail under the effect of the natural conditions such as sunshine wind, the absorption efficiency of plant is not high.In addition, it should be noted that
Nanometer selenium on ordinary meaning refers to restore elemental selenium from selenium salt by chemical reduction method and makes selenium by physical means
Reach nano-scale, the nanometer selenium in this meaning reaction condition and relevant device are required it is of a relatively high, production cost also compared with
Height, but obtained nanometer selenium is still inorganic selenium, and human body can absorb the inorganic selenium of a certain amount of such a form and plays a role in health care,
But dosage strictly to control in order to avoid selenosis, while this nanometer selenium can not be also absorbed by plants.Therefore, applicant considers to receive
Rice silica is carrier adsorption selenium salt and is stably dispersed in water, and another meaning is obtained after nano silicon dioxide absorption selenium salt
On nanometer selenium, it can overcome many deficiencies of selenium-enriched fertilizer in the prior art.
The content of the invention
The present invention provides a kind of nanometer selenium liquid manure solution and preparation method thereof, it is intended to overcome in the prior art selenium-enriched fertilizer it is easy
It is lost in and fails and cause the relatively low deficiency of Selenium in Plants absorptivity.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of nanometer selenium liquid manure solution, it is by following quality
Each material composition of percentage:Nano silicon dioxide 18-22%, sodium selenite 15-20%, Tea Saponin 1.5-2.5%, xanthans
0.1-0.2%, surplus are water.
On the basis of above-mentioned formula, the present invention can also have following further specifically chosen.
Specifically, each material composition by following mass percent:Nano silicon dioxide 20%, sodium selenite 17.6%,
Tea Saponin 2%, xanthans 0.1%, water 60.3%.
Specifically, the particle diameter of the nano silicon dioxide is 50-300nm.
Present invention also offers the preparation method of above-mentioned nanometer selenium liquid manure solution, it includes the following steps：
S1. xanthans is taken and by it according to 5g by corresponding mass percent：The usage ratio of 100-200mL is mixed with water
Close, be sufficiently stirred to obtain xanthan gum solution；
S2. the sodium selenite of corrresponding quality percentage, Tea Saponin, nano silicon dioxide are weighed respectively and are sequentially added into
In xanthan gum solution in S1, then mend and add water to its corresponding mass fraction, after being sufficiently stirred, stand, obtain stable dispersion
Liquid, is the nanometer selenium liquid manure solution.
On the basis of above-mentioned preparation method, it can also have following further specifically chosen.
Specifically, being sufficiently stirred in S1 refers in dispersion machine is sheared, 4500-5500r/min stirrings 6-8h.
Specifically, being sufficiently stirred in S2 refers in dispersion machine is sheared, 7000-8000r/min stirrings 3-4h.
Specifically, the mass ratio of sodium selenite and xanthans is 176 in the nanometer selenium liquid manure solution：1.
Specifically, the mass ratio of nano silicon dioxide and xanthans is 200 in the nanometer selenium liquid manure solution：1.
Specifically, the mass ratio of Tea Saponin and xanthans is 20 in the nanometer selenium liquid manure solution：1.
Specifically, with the mass ratio of water xanthans it is 603 in the nanometer selenium liquid manure solution：1.
Compared with prior art, the beneficial effects of the invention are as follows：
Using nano silicon dioxide as absorption carrier, its porous surface, specific surface area are big and with abundant hydroxyl, adsorption energy
Power is very strong, and sodium selenite can be adsorbed preferably on it, is nanometer selenium after nano silicon dioxide absorption sodium selenite, in it
Selenium element fixed to a certain extent by silica, not easily run off and have and slowly released as extraneous selenium concentration reduces it
The effect of selenium element, i.e. fertilizer efficiency duration are longer, the sorption enhanced rate higher of Selenium By The Plants；Nanometer selenium is more easy to be attached to plant
On root system or blade face and its permeability to plant cell wall is more preferable, therefore sorption enhanced rate higher；Tea Saponin is a kind of excellent
Natural promoter, is on the one hand conducive to the stable dispersion of nanometer selenium liquid manure solution, on the other hand can improve nanometer selenium in plant
Synergistic effect is played in the adhesive force of table, the absorption to selenium；Xanthans is a kind of biogum, collects emulsification and stabilization in certain,
It is remarkably improved the stable dispersion ability of nano silicon dioxide in the solution；In addition, it may also be noted that high concentration contains selenium
Solution is unfavorable for plant growth, and by the method for the present invention sodium selenite can be made to be adsorbed on nano silicon dioxide, then
The selenium to dissociate in solution is relatively fewer, then eliminates in solution selenium concentration height to the adverse effect of plant.
