The specific embodiment of the invention
Of the present invention being described in detail as follows:
Because perlite is not with negatively charged ion, promptly CEC almost approaches 0, in order to separate the shortcoming that must not keep nutrient, uses clay mineral, for example, and the high clay minerals of CEC such as loess, zeolite, wilkinite, snake aragonite.
Above clay mineral has the CEC height, and quality is more stable, buys easily, and is difficult for producing the advantage of decomposing.
The clay mineral that such CEC is high covers on the pearlstone, just can produce to have and can regulate CEC, can regulate the recoverable amount of nutrient and the pearlstone of nutrient.Can also add the organic fertilizer with slow effect as required and make pearlite, proportion is 0.20-0.30g/cm
2Similar to perlite, so there is not particle size separation, need not specific engineering and can add fertilizer, and cover on the pearlstone after fertilizer directly is added on clay mineral or caking agent, play the effect of uniform distribution fertilizer, and can select quick-acting, controlled-release fertilizer, also have the strength ratio pearlstone strong, so rerum natura is with low uncertainty, patience is fine, can also guarantee stable quality.Regulate to cover perlitic addition, the addition of the nutrient during covering and nutrient kind can be produced the mixing prod of plant and different applicable objects.With small amount of clay matter mineral high CEC can be arranged.
The perlitic making of above-mentioned covering is only used clay mineral mud, also can cover.For the caking agent that adds in order to improve bonding efficient, in the choice, not only bonding force wants outstanding, also harmless to plant.
The selection of caking agent is undertaken by following experiment:
(1) selection of organic/inorganic caking agent experiment
The present invention is developed to the pearlite of plant growing ground usefulness with pearlstone, wherein will use caking agent, thus having/selection of inorganic adhesive on, not only the sticking criticality of caking agent wants outstanding, also harmless to plant.
In the selection experiment of caking agent, cover the back bonding force and its weather resistance, weathering resistance are tested according to the KSM5000 standard, compared water-intake rate again, percentage of germination and plant-growth.Selected plant harmless, and the organic/inorganic caking agent that can cover with pearlstone.

(2) pearlstone covers experiment
The method that covers pearlstone has 3 kinds.First kind is the method that is injected in the surface of pearlstone after mixing adhesive solution in the clay mineral mud.Second kind is after spraying adhesive solution in the pearlstone, the method for spraying clay mineral again.The third is that clay mineral and pearlstone mix the method that adhesive solution is sprayed in the back.These 3 kinds of methods all are applicable to continous way, the collocation type mode of production, but first method is the most favourable in the continous way mode of production, and three kinds of methods can in the collocation type mode of production.These three kinds of methods caking agent concentration when covering plays an important role, can regulated at will caking agent concentration from 5-50%, the first method that is fit to the continous way mode of production (can carry out double mass production), because viscosity plays vital role when making mud, so selected experiment of mud and the selected experiment of proportioning have been carried out.This does not mean that the covering method of clay mineral only is defined in first kind.
2-1) the clay mineral mud viscosity is selected
Select to ask the size ratio and the liquid limit of each clay mineral earlier before the viscosity of mud, make mud by 5 kinds of functions between saturated soil that is higher than liquid limit and the supersaturation soil than (with reference to Fig. 1) after, try to achieve the function ratio that is suitable for covering most.
As clay mineral, loess, zeolite, wilkinite, snake aragonite are like table 3, and the fluidity limitation of each argillaceous mineral ratio, size ratio is different.Because all clay minerals are non-plasticity-in the granularity below 35#, measured liquid limit in the granularity more than 100#.Based on its result, after in the product of liquid limit more than 150%, adding the 5 kinds of mud of moisture (10%EVA) making more than the liquid limit, measure the viscosity of (using the viscosimetric analysis device) various mud, cover pearlstone, try to achieve proportion after the drying, water-intake rate (moisture content in pf1.5), fraction of coverage, below 20%, fraction of coverage is a benchmark more than 70% with water-intake rate, has selected best mud function ratio.During covering, the volume of the pearlstone of input is with 10 times of calculating of moisture content volume.For example, when the moisture content of the clay mineral of 100g is 190% (190ml), use the pearlstone of 1900ml, when the moisture content of 100g clay mineral is 210% (210ml), used the pearlstone of 2100ml.

In the experiment of last table 13-15, used proportion to be 0.135-0.155g/ml, granularity 0.5-3mm, the pearlstone of water-intake rate (moisture content in the long power of the moisture of pf0) 60-70%.This is for no other reason than that the big pearlstone fraction of coverage of granularity, and the color ratio is easier to, and does not mean that the kind of pearlstone only is defined in this.
Granule strength is measured with compression resistivity (the compression resistivity is according to the laboratory method of abundant Li Te institute), and the experiment utensil is by compression strength tester, trial jar, fringing ring flange, formations such as test portion compressor.Half test portion of having prepared of dress after the test portion compressor is installed trial jar, strikes about 25 times in trial jar.Aim at the fringing ring flange above the trial jar, add test portion, make it highly reach 1/2 of fringing ring flange and strike again about 25 times afterwards.Remove the fringing ring flange, utilize ruler to remove covering perlite above the trial jar height again.The trial jar of dress test portion is that unit claims with the gram, and this weight can be used at bulk density (bulk density, g/cm
3=test portion weight, g/ trial jar volume, cm
3) mensuration.Trial jar is placed on the compressive strength test apparatus, puts compressed rod above the test portion, no longer falls down as compressed rod, locks auxiliary valve behind the door, compresses test portion (1 time/4-5 second) at leisure, when piston is represented 1 cun (2.54cm), reads instantaneous pressure (kg) by forcer.Thereby produce the compression resistivity.
Compression resistivity (kg/cm
2)=(1 cun compression pressure, kg+ compressed rod weight, kg)/and trial jar area (45.8), cm

Measured the characteristic that covers perlite and pearlstone in order to last method.As table 16
[table 16]
Take this as the standard and drawn dry back proportion more than 0.25, water-intake rate is below 20%, the proportioning of fraction of coverage more than 70%, its result is for after mixing the EVA aqueous solution of 10-30% in the mud that adds loess 40-80g, is that the amount covering of 5-40ml is the most suitable with the content of the EVA aqueous solution in the 100ml pearlstone.
Experimental result when above result just is suitable for making fraction of coverage and being 70% above goods with the continous way mode of production, during in conjunction with actual production, because need the adjusting fraction of coverage, so mud viscosity, EVA concentration etc. is not limited to this.
On the other hand, for CEC, pearlstone covers has different positively charged ions with clay mineral, when mixing use as suitably cooperating, can obtain the color that is consistent with CEC that needs.
The CEC mean value of various clay minerals is: loess 10 ± 2cmol/kg, and zeolite 100 ± 10cmol/kg, wilkinite 50 ± 5cmol/kg, about snake aragonite 30 ± 5cmol/kg, but according to the place of production of mineral, mining period, their value has difference.
CEC is: loess covers perlite 10cmol/kg, about by volume 3cmol/l; Zeolite covers perlite 100cmol/kg, about by volume 30cmol/l; Wilkinite covers perlite 50cmol/kg, about by volume 15Cmol/l, and the snake aragonite covers perlite 30cmol/kg, the about 9cmol/l of volume ratio.And clay mineral covers the multiple CEC that perlite can have 10-100cmol/kg, also can regulate CBC according to proportioning, and the scope of volume ratio is 3-30cmol/l.
(annotate: 10cmol/kg* bulk density (0.3kg/l) is that the 3cmol/l back is also like this)
(3) interpolation of fertilizer
As above, can cover the clay mineral that adds adhesive solution in the pearlstone, the perlite that does not from then on keep the nutrient ability has also had reservation nutrient ability one CEC capacity, is suitable for cultivated plant.
But the required amount that needs nutrient of each plant is different.Therefore, optionally add necessary fertilizer inside the adhesive solution of the present invention.
The amount of fertilizer can arbitrarily be adjusted according to the content of the specific nutrient of each plant needs, and its example such as table 17. but this just illustrate, and the formation of adding fertilizer is not limited to this.
