Description
Technical field
The invention belongs to agriculture fields, specifically design a kind of conditioning that reparation paddy soil heavy metal pollution is built up fertility
Agent.
Background technique
With industrialization, urbanization, agricultural modernization rapid development, pass through metal smelt, agriculture chemical application, life
Approach, the heavy metals discharged into water body, soil and atmosphere such as waste incineration, mud and sewage utilization, motor vehicle exhaust emission also exist
Increase year by year, serious threat has been constituted to ecological environment.The property of heavy metal is relatively stable, is not easy in ecological environment
By biological metabolism, easily by adsorption by soil, there is biological amplification after being enriched in vivo.
Most important crops one of of the rice as China, once a largely accumulation huge sum of money in its root, stem, leaf and seed
Belong to, not only seriously affects the growth and development of plant, but also can enter in food chain, jeopardize human health.
Set about handling heavy metal problem from paddy soil, the soil of repairing heavy metal pollution, increasing soil fertility becomes to carve
Do not allow to delay.
Summary of the invention
The purpose of the present invention is to provide a kind of conditioners that reparation paddy soil heavy metal pollution is built up fertility, and utilize Asia
Amino disuccinic acid tetrasodium salt, polyalcohol as chelating agent, modification sodium bentonite as adsorbent and cation-exchanger,
Cooperate bark and banana skin, not only improve the ability of chelating heavy metal, moreover, Soybean Root and peanut vine is added, improves soil fertilizer
Power and sponginess improve paddy soil.
Specific technical solution of the present invention is as follows:
A kind of conditioner repairing paddy soil heavy metal pollution and building up fertility, including following raw material:
The bark can be used by drying, smashing it through 60-80 mesh.
It after the banana skin dries, crushes, crosses 60-80 mesh, it is spare.
The Soybean Root collects soybean after referring to soybean mature, and the root kept in soil is taken out, and crushes, and crosses 40-60 mesh
Sieve.
After the peanut vine refers to the mature peanut of harvesting, peanut vine in soil will be kept and taken out, crush, cross 40-60 mesh.
The sodium bentonite of the modification the preparation method comprises the following steps:
1), sodium bentonite is added to the water, adds acid, is mixed, reaction is stood；
2) water cleaning, is then added, until filtering, drying to constant weight after supernatant is neutral, crushes, sieving；
3), step 2) treated sodium bentonite heat-activated, smashes and grinds after being cooled to room temperature, and is sieved, is changed
The sodium bentonite of property.
Acid mass concentration described in step 1) is 10-32%, is selected from sulfuric acid or hydrochloric acid, preferably sulfuric acid.
Step 1) the standing reaction stands reaction 2-6h under the conditions of referring to 20-40 DEG C.
The mass ratio of sodium bentonite, water and acid in step 1) are as follows: 1:6-13:4-6.
Step 2) the drying is dried under the conditions of referring to 60-80 DEG C.
Sieving described in step 2) referred to 80-120 mesh.
Heat-activated described in step 3) refers to heating roasting 1.5-2.5h under the conditions of 350-400 DEG C.
Sieving described in step 3) referred to 180-300 mesh.
Preferably, the conditioner repairing paddy soil heavy metal pollution and building up fertility, including following raw material:
It after conditioner provided by the invention mixes, is directly sprinkled into paddy field, 80-150kg/ mus, due to adding for quick lime
Enter, have in rice field water or it is rainy when, have water, make paddy soil in alkalinity, improve acid soil.Moreover, in alkalescent ring
Under border, be conducive to iminodisuccinic acid tetrasodium salt and polyalcohol chelating absorption heavy metal.Containing a large amount of in bark and banana skin
The dentates such as hydroxyl, carboxyl, amino are also beneficial to the chelating absorption of heavy metal.Moreover, bark and banana skin, peanut vine, soybean
Root is turned waste into wealth as waste, waste utilization, as natural organic fertilizer, is increase soil fertility, in addition, Soybean Root is distinctive solid
The phosphorus that nitrogen effect is rich in peanut vine provides nutrition abundant jointly for paddy soil, promotes paddy growth.Bark and banana skin
It is also rich in cellulose, lignin, loosing soil degree is improved, is conducive to paddy growth.Moreover, iminodisuccinic acid tetrasodium salt and
Bark, banana skin, peanut vine etc. are used together, and it is rich that iminodisuccinic acid tetrasodium salt can be enriched with bark, banana skin, peanut vine
The nitrogen contained, phosphorus, potassium and microelement improve soil fertility of paddy field.In addition, bentonite is modified first with acid in the present invention, ionize out
The H come+The sodium ion that interlayer can be displaced increases its negative electrical charge, it is easier to adsorb heavy metal cation；Moreover, swelling
Mud acid is modified, and roasting keeps its structure more loose, and gap increases, and specific surface area is bigger, is conducive to the absorption of heavy metal ion
Diffusion.
Compared with prior art, the present invention be added iminodisuccinic acid tetrasodium salt, polyalcohol, modification sodium bentonite
Cooperation bark and banana skin are conducive to improve the absorption of heavy metal ion Cd, Pb, Hg, Co, Cr etc., have in-situ passivation paddy soils
The function of earth heavy metal reduces content of beary metal in paddy soil and rice.And soil pH value can also be improved, repair acidification soil
Earth, bark and banana skin, the Soybean Root and peanut vine of addition, increases soil fertility, and improves the nitrogen phosphorus and other micro members of soil
Cellulose content, and loosing soil are conducive to paddy growth, improve rice yield.
