Description
Technical field
The invention belongs to technical field of land improvement, and in particular to a kind of place of mining collapse area Reclaimed Soil fertilizing improvement
Reason method.
Background technology
Coal is the important energy in China, and a large amount of exploitations of coal cause earth's surface large area to collapse.After coal mining subsidence area, ground
Table is destroyed, and original arable land gradually forms slope nonirrigated farmland, long-term pools zone, and soil nutrient is by ground line gradient, water erosion, wind erosion, leaching
Molten and element itself migration feature etc. is many-sided to be influenced, and is eventually resulted in the arable land after collapsing and is ploughed compared with before coal mining subsidence area
Geological measuring declines, and soil texture destroys serious.In addition, the substances such as the gangue generated in the process and flyash of mining enter soil
Afterwards, the growth of crops and quality after soil is reclaimed will also be influenced.
Since mining collapse area soil organic matter content and soil fertility are relatively low, a large amount of input chemical fertilizer of Reclaimed Soil needs,
Organic fertilizer could restore its productivity.The main mode mainly digging what of reclaiming in subsidence area is padded at present, increases the use of chemical fertilizer
Amount, improved effect is simultaneously pessimistic, a large amount of instead not only to increase cost using chemical fertilizer, while can cause soil acidification, soil plate
The problems such as knot, soil pollution and body eutrophication；Meanwhile it is excessive using chemical fertilizer, significantly increase greenhouse gases CO2、CH4
And N2The discharge of O.Therefore, it Reclaimed Soil fertility and crop yield can be improved and overcome is excessively used there is an urgent need to one kind
The environmentally friendly compound Peibuganshen of chemical fertilizer disadvantage.
China is large agricultural country, generates a large amount of agricultural stalk every year, and annual agricultural crop straw yield is about 700,000,000 tons,
Wherein about 40% stalk is burned by field.And farmland stalk field burn produce a large amount of volatile organic matter, organic carbon,
The discharges such as carbon monoxide and carbon dioxide.In recent years, China by stover be biomass carbon pyrolysis technology increasingly at
It is ripe, and obtain the support energetically of national government.If biomass carbon is applied to farmland, not only avoid caused by crop straw burning
Greenhouse gases direct emission increases soil carbon sink, and increases soil fertility and crop yield.Therefore, by biomass carbon and nothing
Machine fertilizer use, be not only advantageous to agricultural stalk and recycle, and in energy-saving and emission-reduction, improve soil quality and make produce
It is of great significance in amount and application prospect in agriculture.
Invention content
To solve the above problems, the present invention provides a kind of processing methods of mining collapse area Reclaimed Soil fertilizing improvement.
In order to achieve the above objectives, the present invention uses following technical scheme：
A kind of processing method of mining collapse area Reclaimed Soil fertilizing improvement, includes the following steps：
(1) straw thermal cracking：Wheat crop stalk is collected, air-dries or drying is allowed to water content and is less than 15%, in 400-500
Thermal cracking charing is carried out under the conditions of DEG C high temperature, biomass carbon is generated, then grinds, and is sieved, is obtained particle diameter<0.25mm
Biomass carbon；
(2) topsoil of mining collapse area Subsided Reclamation Region 0-20cm is acquired, soil is excessively spare after 2mm sieves through air-drying, grinding,
Wheat planting is carried out in a manner of potting；
Biomass carbon is mixed according to the amount of application of 1%-2% with NPK inorganic fertilizers with applying in pot experiment soil, will be ready to
Inorganic fertilizer and biomass carbon be proportionally added into soil and be uniformly mixed, pour soil to its field capacity with deionized water
75-80% sows 40 wheat seeds, in five 30 plants/basins of leaf phase final singling after emergence per basin after three days；
(3) ripe to wheat to the management of wheat seedling general planting, it weighs after harvest and calculates yield.
Wherein, the potting culture experiment is carried out in a manner of outdoor potting, and soil 25-30kg, NPK inorganic fertilizer is filled per basin
Respectively by (NH4)2SO4、KH2PO4And K2SO4(analysis is pure) provides, and recommended rate of fertilizer application is calculated with 200 mg/kg soil of pure N.
The present invention has the beneficial effect that：
The present invention is that the biomass carbon for generating straw thermal cracking charing passes through certain processing, according to the application of 1-2%
Amount be used in mixed way with inorganic fertilizer, be applied to mining collapse area Reclaimed Soil have improve soil texture, increase soil fertility with
Dramatically increase the effect of wheat crop yield.Inorganic fertilizer and biomass carbon are remarkably improved soil organic matter, full nitrogen, effectively with applying
Phosphorus and effective potassium composition can realize that crop material farmland recycles and solves to improve Reclaimed Soil fertility and makees produce
The technical issues of amount, and provide a kind of processing method for China mining collapse area controlling measurements.
Figure of description
Fig. 1 applies the influence of different content biomass carbon and inorganic fertilizer to wheat yield.
Specific implementation mode
Embodiment 1
1, potted plant experiment：It is to pick up from Huaibei City Xincai, Anhui Province town mining collapse area for examination soil.The Subsided Reclamation Region is using digging
The shallow mode of deep pad is leveled land, for not used agricultural land soil of newly reclaiming.Subsided Reclamation Region 0-20cm is acquired in October, 2016
Topsoil, soil through air-drying, grinding, cross 2mm sieve after it is spare.
2, potting culture experiment is carried out in March, 2017 in June, 2017 in a manner of outdoor potting.
(1) pot experiment sets 4 processing altogether：(CK) is handled not apply inorganic fertilizer and biomass carbon processing as a contrast；It is raw
3 processing are arranged in substance charcoal, and respectively for inorganic fertilizer with the processing of 0%, 1%, 2% biomass carbon is applied, inorganic fertilizer, which is matched, applies 0% charcoal
It handles (NPK)；Inorganic fertilizer handles (NPKB1) with 1% charcoal is applied；Inorganic fertilizer handles (NPKB2) with 2% charcoal is applied.It will be accurate
The inorganic fertilizer and charcoal got ready are proportionally added into soil and are uniformly mixed, and soil is poured to its field capacity with deionized water
40 wheat seeds are sowed after 80%, three days per basin, in five 30 plants/basins of leaf phase final singling after emergence；
Soil 25kg is filled per basin, NPK fertilizer is respectively by (NH4)2SO4、KH2PO4And K2SO4(analysis pure) provides, recommended rate of fertilizer application with
Pure N 200mg/kg soil calculates.Each 4 repetitions of processing, varieties of plant are wheat seed Jimai 22.
(2) ripe to wheat to the management of wheat seedling general planting, it weighs after harvest and calculates yield.
3, interpretation of result is as shown in table 1, Fig. 1, as it can be seen from table 1 compared with the control, adding biomass carbon, soil pH
It reduces；NPK fertilizer is administered alone and improves only total soil nitrogen and content of inorganic nitrogen in；And NPK fertilizer and biomass matter charcoal are significantly carried with applying
High soil organic matter, full nitrogen, available phosphorus and effective potassium composition, organic carbon content improve 33%-66%, and total nitrogen content improves
71%-119%, soil available phosphorus and potassium content also significantly improve, and the amplitude of increasing respectively reaches 13%-22% and 18%-
28%, wherein 2% biomass carbon dosage obviously compares the increase rate bigger of 1% additive amount, therefore, 2% biomass carbon and NPK
Fertilizer is more preferable to improving Reclaimed Soil fertility effect with applying.And Fig. 1 then illustrates that biomass carbon matches to apply with NPK fertilizer and significantly increases wheat
142% and 163% has been respectively increased in yield, compared with the control, 1% and 2% biomass carbon dosage wheat yield.Therefore, raw
Substance charcoal and NPK fertilizer, which match to apply, is improved largely to soil fertility and crop yield.
Influence of the application biomass carbon of table 1 to soil physico-chemical property
