Description
Technical field
The present invention relates to the regeneration fields of chemical industrial waste object and agricultural wastes, and in particular to a kind of red soil conditioner
And preparation method thereof.
Background technique
South China of China distribution of red soil is extensive, but since (soil hardening holds for dry (not drought-resistant), sour (pH value is low), plate
It is great), the bad character such as thin (available phosphorus is low, nutrient is unbalance), be a kind of low productive soil.Generally by increasing stone in production
Ash is but often ineffective to reduce soil acidity degree.For many years, the researchs such as improvement about red soil acidity are by extensive
Concern, the project as related to red soil acidification improvement in national " 15 ", Eleventh Five-Year Plan plan of science and technology.In the prior art,
There is multidigit scholar to study red soil conditioning technology, but has not been able to solve acid strong, soil hardening, nutrient imbalance, effectively simultaneously
The obstacle for the influence crop growthing developments such as phosphorus content is low, aluminium is malicious.
Patentee is " Jiangxi Institute of Red Soil ", and patent name is " a kind of deacidification moisture control method of Upland Red Soil ",
The patent of Patent No. " 201210518904.4 " discloses a kind of method for improving red soil: utilizing calper calcium peroxide or peroxidating
Magnesium reduces the acidity of soil, changes soil redox potential, adjusts the aqueous vapor ratio of soil, generate simultaneously to Upland Red Soil
Deacidification and damping effect.The defect of the technology is not solve soil hardening, nutrient imbalance, this low three big influence of available phosphorus content
The reason of crop planting.
Patentee is " Institute of Environment and Sustainable Development in Agriculture, CAAS ", and patent name is " a kind of
Red soil improving agent ", the patent of Patent No. " 201110240926.4 " disclose a kind of method for improving red soil, by 30%~
40% red mud, 15%~25% sepiolite, 20%~30% straw biomass be burnt, 10%~15% calcium hydroxide and
10%~15% magnesia mixing is used as conditioner, so that the moderate-elements such as soil acidification, calcium and magnesium supply wretched insufficiency etc. is led
The problem of plant growth of cause is poor, low output is addressed.But the defect of the technology is not solve soil hardening and available phosphorus
This low two large problems of content.Meanwhile the component that the technology is previously mentioned is too many, is unfavorable for being generalized in the vast rural area of China.
Summary of the invention
In order to solve the above technical problems, the present invention utilizes chemical industrial waste object ardealite and agricultural wastes offal and matting
Fertilizer prepares a kind of red soil conditioner, can effectively solve red soil acid strong, soil hardening, nutrient are lacked of proper care, available phosphorus content is low etc.
Problem, and be easy to be promoted in rural area.
Its technical solution are as follows:
A kind of red soil conditioner, by volume, including 90-110 parts of ardealite, decomposed offal 6-8 parts, decomposed dung 5-10
Part.
A kind of red soil conditioner preparation method first crushes offal for 20-40 mesh；Barnyard manure and offal difference stacking curing；
Decomposed offal is mixed well with ardealite, is placed 24-48 hours, is then mixed well again with decomposed dung；Each component ratio is
100 parts of ardealite, decomposed offal 6-8 parts, 5-10 parts of decomposed dung.
The solid waste that ardealite gives off when being phosphate fertilizer, phosphoric acid production.China is the first big ardealite pair in the world
State is produced, 50,000,000 tons of annual emissions, accounts for 70% of industry by-product gypsum or more, and increase every year with 15% speed.Its medium cloud
South saves ardealite annual emissions and accounts for the whole nation 1/5 or so.The country is from the 1970's, in soil such as saline-alkali soil, brown earth, yellow earth, red soil
The research of some ardealite agricultural effects has been carried out on earth, the results showed that, ardealite helps to improve the yield and quality of crop.
But due to the problems such as ardealite itself is acid by force, it is great to glue, and long-term excessive application will lead to soil acidification, bulk density increase.
Microelement is abundant in ardealite, there are also a small amount of available phosphorus, can solve that available phosphorus content in red soil is low and nutrient
The problem of imbalance.If individually using ardealite in red soil, the pH value of red soil can become lower, cause nutrient imbalance tighter
Weight, so that soil is more hardened.Ardealite is mainly used for improving basic soil in northern China, has no on acid soil
There is research.There is ardealite to should not be used in the technology prejudice of red soil conditioning in the art.
Offal is the leftover bits and pieces of production of cigarettes, light, alkaline, and the elements such as organic matter rich in, biological clamps are a kind of
The nuisanceless ecological organic fertilizer of fully natural green.
The problem of offal contains potassium abundant, nitrogen, can solve soil nutrients and soil imbalance.Offal is alkaline matter, be can solve
The acid strong problem of red soil, while the acid strong defect of ardealite can also be offset.Offal bulk density is small, can also be effectively improved soil
Loamy texture, the problem of alleviating soil hardening, while can also offset the big defect of ardealite bulk density.Offal is in Yunnan vast rural area
It can obtain easily, and most of soil in Yunnan belongs to red soil.If offal is used alone, wherein the nicotine contained will affect
The growth and development of crop root.So offal in the art of not applying singly generally is for soil conditioning.
Although decomposed dung nutrient is more comprehensive, since nutrient content is relatively low, when exclusive use, is tended not to effectively
Meets the needs of crop is to nutrient.Therefore, the usual organic fertilizer inorganic fertilizer that needs to arrange in pairs or groups is used in conjunction with.Meanwhile the macromolecular of barnyard manure
Such as humic acid etc, the harmful element in ardealite can be coupled.Application barnyard manure can improve the soil texture, and increasing soil can be thoroughly
Property, it is shared with ardealite, the big defect of ardealite bulk density can also be offset.Farmyard manure and offal ferment together, are easier to send out
Ferment is decomposed, and content of humic acid will increase.
Ardealite, decomposed offal, decomposed dung three ratio according to the invention can solve simultaneously for adjusting red soil
The problems such as red soil acid strong, soil hardening, nutrient are lacked of proper care, available phosphorus content is low, aluminium content is excessively high.
It should be noted that could be mixed in proportion with ardealite after barnyard manure and offal need independent stacking fermentation maturity,
And mixed program is that decomposed offal and ardealite first uniformly mix 24-48 hours, is then sufficiently mixed again with decomposed dung,
It can applied.This is different and determine by pH value and the chemical property of three.According to the source of barnyard manure and composition, pH
Value is not quite similar, generally between 5.6-7.5.Nutriment contained by barnyard manure is more comprehensive, existing a great number of elements, and has one slightly
Secondary element, but these nutrients are in organic matter state more, it is difficult to it is directly absorbed and utilized by crop, it is necessary to by the change in soil
It learns the fermentation of physical action and microorganism, decompose, discharge nutrient gradually, thus fertilizer efficiency is longer and stablize.The general meta-alkali of offal
Property (pH value > 8), ardealite slant acidity (pH value < 4).It can be seen that due to ardealite peracid, offal meta-alkali, the two is unsuitable
It is used alone.And decomposed barnyard manure can be administered alone.Decomposed offal and ardealite mixes 24-48 hours, Ke Yiqi
To the effect of acid-base neutralization.It is mixed again with decomposed dung, three's mix products pH value, can be to avoid singly applying offal close to 6 or so
Or when singly applying ardealite, the problem of leading to peracid or cross alkali.By test, N(12 kg/667m2), P(7 kg/667m2), K
(4.5 kg/667m2) three's mixture ph be 6.8, bulk density 0.786；NPK+ offal (decomposed) mixture ph is 8.6,
Bulk density is 0.436；NPK+ barnyard manure (decomposed) mixture ph is 6.4, bulk density 0.689；NPK+ ardealite mixture ph is
4.7, bulk density 0.946；And NPK+ offal (decomposed)+barnyard manure (decomposed)+ardealite mixture ph is 5.96, bulk density is
0.822。
It should be noted that barnyard manure and offal need difference stacking decomposed before use, could be mixed with ardealite.This is
Because nutrient is in organic matter state more in barnyard manure and offal, directly application is difficult to directly be absorbed and utilized by crop, it is necessary to pass through
Stacking is crossed, under the action of chemistry, physics and microorganism, nutrient could gradually discharge.Certainly, not decomposed barnyard manure and offal are straight
The time for connecing and being applied to soil, can also ferment, decompose by the effect of chemical physical action and microorganism in soil, but need
It is longer, and the two is fermented in the soil, it is most likely that cause crop to burn root.
By repeatedly matching screening and field comparison test, and in view of the materials of ardealite, three kinds of offal, barnyard manure substances
Convenient and use cost finally determines the formula of this red soil conditioner are as follows: phosphorus according to the minimum usage amount of offal and barnyard manure
It 1 part of gypsum, decomposed offal 0.06-0.08 parts, 0.05-0.10 parts of decomposed dung (volume ratio), in production practice, can basis
It needs, properly increases the quantity of offal and barnyard manure.With red soil conditioner made of above-mentioned formula, Kaiyuan City, E Shan in Yunnan Province
On the ground such as county, Xuanwei City red soil, tested on four kinds of sugarcane, soybean, corn, potato crops respectively, with N(12 kg/
667m2), P(7 kg/667m2), K(4.5 kg/667m2) it is basic fertilizer (CK), offal (decomposed) (T1), barnyard manure are applied respectively
(decomposed) (T2), ardealite (T3), red soil conditioner, as a result, it has been found that: compared with CK, sugarcane, soybean, corn, potato difference
Volume increase 10.7%, 8.9%, 8.6% and 9.2%；More singly apply offal (decomposed), barnyard manure (decomposed), ardealite averagely increase production 3.53 times,
2.90 times and 3.53 times, difference reaches the level of signifiance；Soil pH value is respectively 5.54,6.43,6.21,5.38,5.93；The soil weight
Respectively 1.43,1.22,1.28,1.49,1.36；Soil alkali-hydrolyzable nitrogen (mg/kg) is respectively 89,129,117,87,109；It is quick-acting
