Description
Technical field
2. the invention discloses a kind of acid soil conditioning agent, belong to field of environment engineering technology.
Background technology
4. acid soil main Types have laterite, red earth, red soil, yellow-red soil, it is distributed in zonality.By soil parent material, into
The influence of native factor, has the characteristic of " sour, lean, malicious, plate, leakage ".During southern dry land acidic soil raise crop, it can destroy some
The permeability of plasmalemma in plant, causes to reduce absorption of the crops to elements such as calcium, magnesium, potassium, Agricultural Output rate is relatively low.But
Such soil is wide as agricultural land distribution, and area is big, and productive potentialities are very big.Pass through the application pair of agricultural various technologies, product
It is improved, is increased fertilizer, you can as the important production base of the southern subtropical zone industrial crops of development and forest, fruit tree.
Agricultural there are about 200,000 km with field2The pH of soil is less than 5.0.Soil pH is too low, makes the saturating of plasmalemma in plant
Property is destroyed, and causes reduction of the crop to Nutrient Absorptions such as Ca, Mg, K.People are accustomed to improveing acid soil with lime
Earth.Liming is the more effective and classical method for improveing acid soil and eliminating aluminium poison.According to Meng's blessing etc., red soil
Liming eliminates aluminium poison, adds grain yield of rapeseed and stalk yield, improves the fertilizer utilization efficiency of rape.But
It is that soil water-soluble state potassium and exchangeable potassium content decrease, and soil available phosphorus content is reduced with the rising of soil pH value.
A large amount of or chronic administration lime can not only cause soil hardening and form " the hardened field of lime ", and can cause soil calcium, potassium, magnesium
The dysequilibrium of 3 kinds of elements and cause the underproduction.It is also possible to cause being total to for magnesium and aluminium hydrated oxide in acid soil liming
Precipitation, reduces the Mg in the soil liquid2+Activity and plant availability.Edmeades thinks, under field condition after liming,
Magnesium, which is replaced out, is subject to leaching loss, causes soil exchangeable content of magnesium to reduce.Therefore, the exploration of acid soil improvement new method is
Vast soil and Plant Nutrition workers' question of common concern.
Therefore, the shortcomings that conventional soil conditioning agent is bad to the improved effect of acid soil how is improved, to obtain higher
The soil conditioner of comprehensive performance, is that it is promoted and applies, meets industrial production demand urgent problem to be solved.
The content of the invention
The present invention solves the technical problem of：Lacked for conventional soil conditioning agent is bad to the improved effect of acid soil
A kind of point, there is provided acid soil conditioning agent.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of acid soil conditioning agent, is made of the raw material of following parts by weight：20~30 parts of silkworm excrements, 10~20 parts of charing flowers
Raw shell powder, 10~20 parts of charing bagasse powder, 8~10 parts of Arabic glues, 8~10 parts of agar solutions, 8~10 parts of Modified Activated Carbons
Change bone meal, 8~10 parts of modified rice brans, 8~10 parts of wormcasts, 8~10 parts of modified meerschaums, 8~10 parts of bacteria celluloses, 80~
100 parts of water.
It is described charing peanut shell powder preparation process be：Peanut shell crushes, insulation charing, cooling, up to peanut is carbonized
Shell powder.
It is described charing bagasse powder preparation process be：By bagasse steam explosion, bagasse powder is obtained, by bagasse powder
Insulation charing, cooling, up to bagasse powder is carbonized.
It is described Arab glue preparation process be：By Arabic gum and water in mass ratio 1：50~1：100 mixing swellings
Afterwards, heating stirring dissolves, up to Arabic glue.
The preparation process of the agar solution is：By agar and water in mass ratio 1：50~1：After 100 mixing swellings, heating is stirred
Dissolving is mixed, up to agar solution.
The preparation process of the modified charred bone meal is：Bone is crushed, insulation charing, obtains charred bone meal, will carbonize bone
Powder is mixed with hydrogen peroxide, and heating stirring mixing, filtering, obtains single treatment charred bone meal, by single treatment charred bone meal and DOPA
Amine aqueous solution in mass ratio 1：30~1：50 are stirred, filtering, up to modified charred bone meal；The bone is ox bone, sheep bone or
Any one in chicken bone.
The preparation process of the modified rice bran is：Count in parts by weight, by 20~30 parts of rice brans, 2~3 parts of biogas slurries and 30~
40 parts of water mixing, fermentation, obtains ferment rice bran, and ferment rice bran hot pressing crushes, up to modified rice bran.
The preparation process of the modified meerschaum is：By sepiolite and water in mass ratio 1：20~1：30 are stirred, cold
Freeze, thaw cycles, filtering, obtains single treatment sepiolite, by single treatment sepiolite and hydrochloric acid in mass ratio 1：100~1：120
Heating stirring mixes, and filters, and washs, dry, up to modified meerschaum.
The beneficial effects of the invention are as follows：
（1）The present invention is by adding silkworm excrement, first, substantial amounts of alkaloid, alkaloid and acid group in soil is contained in silkworm excrement
Divide and react, so that acid soil is improved, secondly, the alkaloid in silkworm excrement can be adsorbed soil colloids
Aluminium ion and the hydroxyl aluminium ions of various nominal pricies fix, exchangeable aluminum content in soil is reduced, so that acid in reduction system
The content of component so that the acidity of soil is further improved；
（2）The present invention is by adding modified charred bone meal, and first, bone meal strengthens the adsorptivity of bone meal through charing, then through hydrogen peroxide
Immersion, strengthens the activity of charred bone meal surface active groups, strengthens the absorption property of charred bone meal, then soak through dopamine solution
Bubble, since dopamine is negatively charged, can attract the hydroxyl aluminium ion of the aluminium ion and various nominal pricies adsorbed in acid soil, fixed
Exchangeable aluminum in soil, reduce soil in exchangeable aluminum content so that in reduction system acidic components content so that soil
Acidity is further improved；
（3）The present invention contains substantial amounts of organic matter, the addition of organic matter, significantly carries by adding modified rice bran in modified rice bran
The content of high soil with organic matter, so as to promote the formation of aluminium organic double compound, reduces exchangeable aluminum content in soil, so as to drop
The content of acidic components in low system so that the acidity of soil is further improved；
（4）The present invention is mixed by modified meerschaum, sepiolite with water, is swollen rapidly and is dismissed, and forms individual fibers or smaller
Fibre bundle be dispersed into the network to condition each other at random, and increase volume, through freezing repeatedly, thaw cycles, widen Hai Pao
The porosity of stone, increases the specific surface area of sepiolite, since sepiolite has great specific surface energy, can adsorb in soil and inhale
After the hydroxyl aluminium ion of attached aluminium ion and the hydroxyl aluminium ion of various nominal pricies, attached aluminium ion and various nominal pricies is adsorbed, easily
Polarization generation activated complex, so that exchangeable aluminum in fixing soil, reduces exchangeable aluminum content in soil, so as to reduce system
The content of middle acidic components, so that further such that the acidity of soil is improved.
