Description
Technical field
The present invention relates to a kind of Solid/liquid two purpose fertilizer and preparation method thereof, specifically a kind of water-soluble solid siliceous fertilizer
Preparation method, the solid siliceous fertilizer can be mixed with a certain proportion of water, and liquid silicon fertilizer is made, and be used for foliage-spray.
Background technique
Silicon plays an important role in the mineral matter nutritional of plant.Studies have shown that element silicon can improve the anti-of crop
Sick ability, improves crop drought resistance lodging tolerance and raising crop salinity and alkalinity resistance etc. at reduction heavy metallic poison.Practical application table
Bright, silicon and nitrogen, phosphorus, potassium scientific matching are applied, and can just play the effect of high yield.Studies have shown that increasing production of rice can be made by applying siliceous fertilizer
7.6%~18.2%, make sugarcane production-increasing 27~36.4%, soybean yield-increasing 5.6~11.8%.
Silicon is the element of the second abundance on the earth, but most silicon are difficult to be absorbed by plants, only when silicon is with molecular state
Or could be efficiently used by plant after ionic state dissolution, referred to as " effective silicon ".
China's anthropogenic soil generally lacks silicon, and south is seriously in the north.Foreign literature is recorded, and can give state SiO in soil2Contain
Measuring < 130mg/kg is to lack silicon, and it is effective to apply silicon.Data shows that China is that southern subtropical zone has 70% or so soil to lack
Silicon, available silicon content is general only in 80-120mg/kg, and Alluvial deposit soil from Yangtze River and lacustrine deposits rice soil available silicon content are in 200mg/
Kg or more.
Some siliceous fertilizers are prepared at present with industrial silicate-containing slag, such as steel slag, but its dissolution is slowly, and fertilizer efficiency is lower；Or with
Quartz sand with soda ash is levigate mix thoroughly after in 1300~1400 DEG C of meltings preparations, this method energy consumption is very high, to equipment requirement
It is very high；Also useful silicon-containing solid waste, if prepared by flyash and activator, though this method turns waste into wealth, its is potential
The harm such as heavy metal pollution cannot ignore.
Summary of the invention
The object of the present invention is to provide a kind of process of preparing of safe quick-acting water-soluble solid siliceous fertilizer, use natural
Cheap quartz sand is raw material, realizes the activation of silica, and more than 20%, obtained siliceous fertilizer has Product Activity silicone content
Have water solubility, and it is obtained be formulated directly into liquid silicon fertilizer, the siliceous fertilizer of production can realize the passivation of heavy metal.
A kind of process of preparing of water-soluble solid siliceous fertilizer, including processing method below and step:
1) quartz sand is milled to 120 mesh or more with the broken machine of electromagnetic powder, quartz powder is made, it is spare；
2) quartz powder and activator are added in crucible according to the mass ratio of 0.1~1.2:1, are sufficiently stirred, are made
Stock；
3) it will stock up and be put into Muffle kiln roasting 30-150 minutes that are preheated to 100-1100 DEG C, take out cold in drier
But 30-40 minutes, it is produced above that 120 mesh are ground to.
Furthermore, in step 1), the content of silica needs >=90% in quartz sand.
Furthermore, in step 2), the activator is sodium hydroxide, potassium hydroxide, calcium carbonate, calcium oxide, hydrogen-oxygen
Change one of calcium or a variety of.
Furthermore, in step 2), the mass ratio of the activator and quartz powder is 0.1~1.2:1.
Furthermore, in step 2), the mass ratio of the activator and quartz powder is 0.45-0.55:1.
Furthermore, in step 2), based on sodium hydroxide, can mix with other activators makes the activator
With when other activators are added, the ratio of sodium hydroxide need to be more than or equal to 80%, and the ratio of other activators, which is not done, strictly to be wanted
It asks.
Furthermore, in step 3), maturing temperature is 100-1100 DEG C, and calcining time is 30-150 minutes；Muffle furnace
Assigned temperature need to be preheated to.
Furthermore, in step 3), the temperature of the calcination process is 600-900 DEG C, and calcining time is 60 minutes.
Furthermore, in step 3), after the completion of roasting, take out immediately be put into drier it is cooling, cooling time 30-
40 minutes；It needs to be ground to 120 mesh or more after cooling.
In addition, the present invention also provides water-soluble solid silicon made from a kind of preparation process of above-mentioned water-soluble solid siliceous fertilizer
Fertilizer.
By above-mentioned technical proposal, the invention has the following beneficial effects:
1) preparation process of the invention is simple, active silicon concentration reaches 20% or more in short production cycle, product, meets
" NY/T 797-2004 siliceous fertilizer " standard is conducive to plant absorption and utilizes, to achieve the purpose that increasing both production and income；
2) traditional siliceous fertilizer production technology need to be heated to 1300 DEG C -1400 DEG C, and energy consumption is very high, also high to equipment requirement, we
Method need to only roast at 600 DEG C -900 DEG C, and allow continuous production；
3) raw material quartz sand of the invention, potassium feldspar, diatomite etc. are from a wealth of sources, and utilization is at low cost, can when producing siliceous fertilizer
To gather materials on the spot, transportation cost is low, solves huge caused by China's siliceous fertilizer is produced because of reasons such as raw material, technique, energy consumption and equipment
Notch；
4) siliceous fertilizer produced by the invention, can will be prepared by the present invention when needing to carry out foliage-spray due to good water solubility
Siliceous fertilizer and water use after being mixed in a certain ratio uniformly；
5) siliceous fertilizer produced by the invention has good passivation effect to heavy metal, can mitigate heavy metal after application to crop
Persecution.
