Abstract
The invention belongs to the technical field of soil improvement, and particularly relates to a fertility-increasing and pollution-controlling soil conditioner and a preparation method thereof. The invention provides a soil conditioner with the functions of increasing fertilizer and controlling pollution, which comprises the following components: urinary formaldehyde, potassium dihydrogen phosphate and a heavy metal adsorption material. In view of the defects of the conventional repairing materials, the second object of the invention is to provide a preparation method of the fertility-increasing and pollution-controlling soil conditioner. The invention not only can provide fertilizer required by crop growth, but also can not be absorbed by plants due to passivation of heavy metal at the periphery of crops in the process of fertilizer absorption, thereby achieving the purpose of directional regulation and control. The product has low cost and simple formula, can improve the soil fertility and the soil pH value on one hand, and has obvious passivation effect on heavy metal pollutants.
Description
Technical field
The invention belongs to technical field of land improvement more particularly to a kind of getting fat pollution control type soil conditioner and its preparation sides
Method.
Technical background
Acid soil is soil general name of the pH value less than 7.In general, China's acid soil is mainly distributed on the south the Changjiang river and cloud
The ground such as Gui Chuan.However, also there is large area Farmland Soil Acidification in northern area as chemical fertilizer is a large amount of in recent years and is used for a long time
Phenomenon.Soil acidification, it will usually destroy soil aggregate structure, cause hardened, reduce the gas permeability and microbial activity of soil；And
And aluminium ion, iron ion, manganese ion content increase, and interfere being absorbed and utilized for other various metals mineral elements, cause to poison；
Meanwhile the activity of heavy metal ions in soil is also added, it makes it easier to be absorbed by crops, exacerbates the harm of heavy metal.
In addition, pesticide use for many years is but also the pesticide remaining quantity in soil increases, destruction rhizosphere soil is ecological.These above-mentioned factors are led
Cause plant growth bad, disease resistance is poor, and yield reduces.Increasing soil acidification and pollution problem have become China's agricultural
The big obstacle of the one of sustainable development.
In the past, what people often more paid attention to is soil acidification problem, and has ignored heavy metal and remains of pesticide to soil
Harm.This is resulted in after having used soil conditioner, and soil acidification problem alleviates, but heavy metal and Pesticide Residue are still
So exist.
It because existing heavy metals in farmland is seriously polluted, needs to repair, but previous repair materials main function is regulation soil
PH, it is heavy metal-passivated, fertilizer needed for plant growth can not be provided, therefore do not have to grow using crop root to the characteristics of fertilizer and reach
To the purpose of the regulation of orientation, to cause, repair materials dosage is big, and costly, peasant can not receive.
Summary of the invention
In order to solve the above technical problems, an object of the present disclosure, which provides a kind of getting fat pollution control type soil conditioner, can not only mention
For fertilizer needed for crop growth, and crops are during absorbing fertilizer, since the passivation of its periphery heavy metal is not to can
It is absorbed by plants, achievees the purpose that orientation regulation.
The present invention solves its technical problem institute, and the following technical solution is employed is:
A kind of getting fat pollution control type soil conditioner, the conditioner ingredient include: that urine formaldehyde, potassium dihydrogen phosphate and heavy metal are inhaled
Enclosure material.
As a further improvement, the molar ratio of urea and formaldehyde in the urine formaldehyde is 1.3~1.4.
As a further improvement, urine formaldehyde, potassium dihydrogen phosphate and heavy-metal adsorption material mass component ratio are as follows: 30%-40%,
10%-20% and 40%-60%.
As a further improvement, heavy-metal adsorption material includes the modification material of sepiolite, palygorskite and its sulfydryl and amino
Expect the mixture of composition.
As a further improvement, sepiolite and palygorskite ratio are 1:1.
As a further improvement, the modified material of the sulfydryl and amino is sepiolite and palygorskite mass fraction 1/4-
1/3。
In view of the deficiency of previous repair materials, the second mesh of the invention provides a kind of getting fat pollution control type soil conditioner
Preparation method.
The following technical solution is employed for its technical problem institute:
A kind of preparation method of getting fat pollution control type soil conditioner, this method include mixing sepiolite with palygorskite 1:1
Object is scattered in 80 DEG C of -100 DEG C of hot water and on dispersion machine with speed high-speed stirred 5-10 minutes of 10000 revs/min, is formed
The modified material of sulfydryl and amino that mass fraction is sepiolite and palygorskite mass fraction 1/3-1/4 is then added in suspension
The mixture of composition continues stirring 10-20 minutes, dispersion machine is then slowly added to phosphorus under 2000-5000 revs/min of revolving speed
Acid dihydride potassium and urine formaldehyde stop stirring after potassium dihydrogen phosphate and urine formaldehyde all dissolve, finally mixing are granulated and are dried,
Finished product is made.
As a further improvement, the mixture that the modified material of the sulfydryl and amino forms is 3- mercapto propyl trimethoxy
Base silane and 3- aminopropyl trimethoxysilane mixture.
Product cost of the invention is low, formula is simple, and soil fertility on the one hand can be improved, and promotes soil pH value, and counterweight
Metal pollutant has apparent passivation.
Specific embodiment:
A kind of getting fat pollution control type soil conditioner, the conditioner ingredient include: that urine formaldehyde, potassium dihydrogen phosphate and heavy metal are inhaled
Enclosure material；Urinate formaldehyde, potassium dihydrogen phosphate and heavy-metal adsorption material mass component ratio are as follows: 30%-40%, 10%-20% and 40%-
60%；The molar ratio of urea and formaldehyde in the urine formaldehyde is 1.3~1.4；Heavy-metal adsorption material includes sepiolite, slope
The mixture of the modified material of thread stone and its sulfydryl and amino composition；Sepiolite and palygorskite ratio are 1:1；The sulfydryl and
The modified material of amino is sepiolite and palygorskite mass fraction 1/4-1/3.
