Point.
The method that a kind of utilization wet-land pine tree container seedling of the present embodiment directly repairs metal abandoned mine slag muck, including following step
Suddenly：
(1) Slash pine seed germination：The warm water that Slash pine seed is placed in 60 DEG C is soaked seed 2-3 days, warm water is changed in centre
1-2 times, seed is carried out disinfection 2h with 0.2% potassium permanganate solution, then rinsed well with clear water.After Slash pine seed vernalization
Directly it is sowed in large size deep hole nursery cave, seedling medium is peat：Husk：Vermiculite (volume ratio)=2:1:1, and mix with calcium and magnesium phosphorus
Fertilizer (6kg/m3) and carbendazim (0.2kg/m3) fully mix.2-3 is sowed in each cave, a thin layer of fine sand is covered with, it is pending
After bud seedling, each cave is colonized 1 plant of seedling, and in the nursery cave being short of seedling, water spray determines root after field planting for unnecessary sprigging.
(2) nursery stock management：Temperature control and diseases prevention.Seedling easily causes under high-temperature exposure burns day, in continuous overcast and rainy, sprout
Easily there is samping off, therefore to be poured according to soil dry-wet according to specific weather conditions sunshade net temperature control, ventilative in Seedling Stage
Water, in sprout rudiment and transplanting early stage, water management will accomplish appropriate, multiple, and spraying 1-2 times daily is sprayed in the morning or at dusk
Mist 1min, makes Nutrition Soil keep moisture state, promotes lateral root growth；Fast-growing stage want volume, few time, Nutrition Soil reaches certain
Rewatered after degree of drying.Additionally, because containing part nutritional ingredient in nutrient matrix, so the growing way according to Pinus elliottii seedlings is fitted
As the N with 3% concentration:P:K=20:20:20 full nutrition Water-solubility foliar fertilizer is topdressed.
(3) it is transplanted to degradable nonwoven fabrics container bag：Because of the severe land occupation condition of abandoned mine slag, without the soil that plant growth needs
Earth structure and nutritional condition, so the specification of container bag is big compared with traditional lightweight matrix specification, it is 20cm × 20cm.And in selection
During culture matrix, as far as possible using available resources near mining area, matched by different substrates, find wet-land pine tree and given birth in abandoned mine slag
The optimal container matrix of length.Nutrition Soil (yellow soil and baked wheaten cake soil) used is sieved after fully smashing, and removes bulk
The debris such as chad, tree root.A certain proportion of peat soil, wood chip, husk and yellow soil, baked wheaten cake soil are stirred, is preferably being stirred
A small amount of clear water is sprayed when mixing, in case fine earth is blown away.It is pre- preventing disease and pest, adds 3% industrial ferrous sulfate 25kg/m3, use
Covered rearing with plastic film was fitted into container bag after 2-3 days.Because south moistening is rainy, and wet-land pine tree has preferable drought tolerance, institute
Not add water-loss reducer in matrix.Roll into a ball to be formed in Pinus elliottii seedlings root system, during length to 12-15cm or so, by nursery stock and culture medium
Matter is transplanted in degradable nonwoven fabrics container bag together.
(4) container seedling management：Transplant early increases dose, is applied per 10d with the full nutrition Water-solubility foliar fertilizer of 6% concentration
Fertilizer once, continuous fertilization 3-4 times.At later stages, before soon going out garden, applied nitrogen is stopped, using phosphate fertilizer and potash fertilizer, dose
It is potash fertilizer：Phosphate fertilizer=200g：100g, to water 50kg, allows nursery stock lignifying.
(5) mining area abandoned mine slag aheap site preparation：Aheap hillside fields geological stability is poor for abandoned mine, thus segmental stability compared with
It is poor it is domatic carry out engineering improvement, the domatic gradient that makes into of the poor debris of edaphic condition is relatively delayed into relatively stable slope,
Digged pit on abandoned mine slag, container seedling is grafted directly in barren rock hole, container bag bottom is scratched during plant, smooth cave after transplanting
Face, distance between rows and hills is 1.5 meters × 1.5 meters.After 1 year, wet-land pine tree can 0.5-0.8m long or so, it is annual additional if conditions permit
Azophoska 1-2 times, wet-land pine tree growing way can be more preferable.
(6) transplant：Wet-land pine tree container seedling goes out garden standard for seedling root group is sufficiently formed, height of seedling more than 20cm, now
Garden can be gone out to be afforested.It is not sufficiently formed for root ball, the nursery stock that growing way is more weak can not emerge.Nursery stock is when garden is gone out
Shipped with seedling frame, anti-extrusion backfin seedling, accomplished with cultivation with fortune seedling.Wet-land pine tree container seedling can almost accomplish that the anniversary afforests, but one
As preferably 2 months, May, September transplanting.
To degradable nonwoven fabrics container bag, substrate composition is particularly significant, and the present embodiment is to carrying out substrate composition for Nursery stock transplanting
Experiment：
The abandoned mine slag that Mine Abandoned Land is piled up is given up by the various solids produced in mining, ore dressing and processing smelting process
Gurry is constituted, soil texture and nutrient needed for not only lacking plant growth, and retain water and nutrients ability is poor, so often
The light ground mass wet-land pine tree container seedling of rule may be not suitable with slag land occupation condition.First, it is contemplated that south is generally characteristic of acid red soil, wet
Pine is acidophilous plant on ground, can secrete a large amount of small molecular organic acids, so half wind of the matrix soil from silt content 40% or so
The yellow soil of change, not only can suitably reduce the generation of pest and disease damage, and porosity 50% or so, with certain retain water and nutrients energy
Power, cooperates with soil is burnt, and can improve the effective Vegetation space of nursery stock under ground portion, is allowed to fully absorb nutrient.Secondly because
Abandoned mine slag lacks the nutriment that plant growth needs, although can be with artificially applying fertilizer, but the nutrient pool level improved in matrix can
Survival rate of the wet-land pine tree container seedling in abandoned mine slag muck is effectively lifted, so adding the agricultural such as wood chip, husk to give up in substrate composition
Gurry, turns waste into wealth, and can provide abundant organic matter to container seedling growth.Further, peat is current container nursery using most
Wide matrix components, not only density is small, and ventilative, retentiveness is good, and salt content is low, and the formation to seedling root aggressiveness extremely has
Benefit.So meet wet-land pine tree by substrate composition discards ground very in the growth demand of abandoned mine slag muck to wet-land pine tree repairing mine
Important, substrate composition ratio is as shown in table 2.
The substrate composition ratio (volume ratio) of table 2
| Matrix | Yellow soil | Burn soil | Peat | Husk | Wood chip | Slow-release compound fertilizer kg/m3 |
| A | 3 | 3 | 1 | 1 | 1 | 5 |
| B | 2 | 2 | 2 | 2 | 2 | 5 |
| C | 1 | 1 | 3 | 3 | 2 | 5 |
| D | 2 | 2 | 3 | 2 | 1 | 5 |
The growth conditions of the different substrates wet-land pine tree container seedling of table 3
| Matrix sequence number | Height of seedling/cm | Ground diameter/cm | Average every plant of fresh weight/g | Average every plant of dry weight and fresh weight of plant seedlings/g |
| A | 20.14 | 0.44 | 3.65 | 0.59 |
| B | 28.31 | 0.50 | 4.75 | 0.84 |
| C | 29.71 | 0.51 | 4.92 | 0.97 |
| D | 30.50 | 0.54 | 5.02 | 0.99 |
Growth conditions of the different substrates wet-land pine tree container seedling of table 4 in Mine Abandoned Land (after transplanting 2 years)
| Matrix sequence number | Height of seedling/cm | Ground diameter/cm | Survival rate/% |
| A | 113.5 | 1.97 | 65 |
| B | 140.7 | 2.65 | 91 |
| C | 103.2 | 1.56 | 74 |
| D | 135.6 | 2.80 | 87 |
As can be seen from Table 3, growth conditions of the wet-land pine tree in different culture media matter show more significant growth differences,
The soil constituent ratio of yellow soil and baked wheaten cake soil is higher, and wet-land pine tree container seedling growth speed is slower；Peat soil ratio is higher, container
Seedling growth is rapider.D substrate composition (yellow soils：Fiery wood chip earth burning：Peat：：Husk=2：2:3:2:1) with maximum seedling
High, height growth, illustrates that properly increasing peat ratio may advantageously facilitate Growth of Pinus elliottii.Wood chip ratio is big compared with D in B matrix,
Wet-land pine tree container seedling growth rate is slow compared with D, it may be possible to after wood chip is soaked relatively closely, is ventilated after mixing with yellow soil and baked wheaten cake soil
Water penetration is slightly worse, absorption of the influence nursery stock to moisture and nutrient.
But seedling plants are transplanted to the growth result of the growth result of Dexing copper mine abandoned mine slag and container seedling in table 3 in table 4
It is inconsistent.Table 4 shows, after the basically identical wet-land pine tree container seedling of growth is transplanted to ettle stockyard, yellow soil and baked wheaten cake soil contain
The wet-land pine tree survival rate of amount soil matrix (A proportionings) higher is than yellow soil and burns relatively low matrix (C proportionings) height of native content,
Growth rate is very fast, illustrates the certain soil constituent of the growth needs of the wet-land pine tree in abandoned mine slag as substrate.But B and D matrix
Mix proportion scheme still shows preferable growth vigor in slag stockyard.
The result of cultivation of container seedling and abandoned mine slag Adaptable growth aheap is considered, using B and D substrate composition schemes
Repairing effect of the wet-land pine tree container seedling to mining area abandoned mine slag aheap it is preferable.But due to non-renewable, the money of mud and charcoal
Source is more in short supply, and price is higher, and the agriculture and forestry organic waste material resource such as wood chip and husk is more, so still using gold zone field：Burn soil：
Peat：Wood chip：Husk=1：1：1：1:1 used as wet-land pine tree container seedling culture matrix, and cost is relatively low, nursery stock mining area grow compared with
It is good, restoration of the ecosystem remarkable benefit, it is easy to popularization and application.
