Abstract

The invention discloses a manufacturing method for nutritional bowls for planting trees on coal gangue piles and belongs to a method for restoring ecological vegetation on mines. The method comprises mixing dry cow dung, plant fibers, carbonate rock powder, charcoal powder, magnesium ammonium phosphate, polyacrylamide and potassium mineral powder with the potassium content of 7% according to a mass ratio of 60:20:10:5:2:2:1; performing die molding on the mixture into cylindrical bowl bodies with inner diameters of 8cm, wall thicknesses of 3cm, bottom thicknesses of 4cm, heights of 20cm and densities of 330 Kg/m<3> after adding water and mixing the mixture uniformly; and drying the cylindrical bowl bodies. The manufacturing method has the advantages of being simple in manufacturing, low in cost, small in utilization amount of planting soil, high in sapling survival rate and the like. The manufactured nutritional bowls are particularly suitable for planting nursery stocks on surfaces of coal gangue piles.

Description

Coal gangue hill is planted trees with the preparation method of nutritive cube

Technical field

The present invention relates to a kind of the tree planting with the preparation method of nutritive cube, relate in particular to a kind of coal gangue hill and plant trees with the preparation method of nutritive cube.

Background technology:According to the interrelated data statistics, about 200,000,000 tons of the gangue of the annual discharging of China, cumulative amount over the years reaches 3,500,000,000 tons, about 220,000 hectares of floor space.The gangue of enormous amount is deposited in the mining area and forms the slag mountain.These discarded objects are under influences such as weathering, precipitation leaching, migration transform, and the heavy metal of inside, slag field, highly acid material can discharge in peripheral water body, soil, the biotic habitat, cause serious environmental to pollute and ecological disruption.In addition, the slag that pile up like a mountain forms the landslide that caves in easily because the gradient is excessive, produces geological disasters such as debris flow.How to administer coal gangue hill, become the vital task that environment of mining area is administered.

Planting vegetation at coal gangue hill is one of effective way of administering coal gangue hill.At present, the method in coal gangue hill surface plantation vegetation mainly has or not earthing directly to plant, on-the-spot earthing is planted, drought resisting is planted etc.No earthing is directly planted and only is applicable to that weathering is serious, topsoil is grown coal gangue hill preferably, but because coal gangue hill surface waste lacks nutrients such as necessary for plant growth N, P, K, and the gangue leaching liquor is acidity or highly acid more, the vegetation growth difficulty.In addition, gangue has stronger heat absorption capacity, and summer, the coal gangue hill skin temperature can be up to 42 ℃, and seedling is easily burnt and death; Therefore, the direct method for planting of no earthing seldom adopts in the coal gangue hill vegetation recovery engineering.On-the-spot earthing is planted and is had that the soil moved in to improve the original quantities is big, cost is high, and the regional ecological disruption of fetching earth is serious, and soil is defective such as loss easily.The drought resisting method for planting need adopt the water-loss reducer technology, covers the water conservation technology, ABT root-inducing powder technology waits to improve survival rate and the storage rate of nursery stock, but has ignored factors such as coal gangue hill nutritional deficiency, sour environment be abominable, so the restoration of the ecosystem poor effect.

Summary of the invention:At the defective that has revegetation difficulty, cost height, weak effect in the present coal gangue hill restoration of the ecosystem, the present invention aims to provide a kind of coal gangue hill and plants trees with the preparation method of nutritive cube, and the nutritive cube of making of this method can improve the survival rate that starts seedlings at the gangue massif.

To achieve these goals, the present invention is by the following technical solutions: will do cow dung, vegetable fiber, carbonate rock powder, charcoal powder, ammonium magnesium phosphate, polyacrylamide, potassium content and be 7% potassium breeze and mix by the 60:20:10:5:2:2:1 mass ratio, and be molded into internal diameter behind the poach and be 8cm, wall thickness and be 3cm, base thickness and be 4cm, highly be that 20cm, density are 330Kg/m ³Tubular alms bowl body, dry then.

In technique scheme, described vegetable fiber is paper pulp or wood shavings.

Compared with the prior art, the present invention has been owing to adopted technique scheme, the H that the carbonic acid rock salt powder in the alms bowl body matrix can be in a long time discharges with gangue ₂SO ₃, H ₂SO ₄Generate sl. sol. CaSO Deng reacting ₄, the organic matter in the matrix also can react with acid ingredient simultaneously, thereby improves the pH of the soil body jointly.Cow dung, paper pulp (or saw foam) not only can generate the humus that is conducive to the plant growth, the heavy metal ion that the complexing of charcoal powder energy, absorption gangue discharge; And can also reduce heavy metal ion such as iron root system of plant is caused damage as the buffering isolation strip of plant and gangue, for the growth of plant provides a good outside subenvironment.Polyacrylamide in the matrix can be the plant growth as water-loss reducer provides part moisture, ammonium magnesium phosphate, potassium powder, cow dung etc. can provide growth necessary nutriment; Therefore the root system of plant external environment condition is good, moisture, nutrient abundance, survival rate height.The present invention have make simple, cost is low, few, the sapling survival rate advantages of higher of plantation soil consumption.

Embodiment:The invention will be further described below in conjunction with specific embodiment:

Be that 7% potassium breeze mixes by the 60:20:10:5:2:2:1 mass ratio with doing cow dung, vegetable fiber, carbonate rock powder, charcoal powder, ammonium magnesium phosphate, polyacrylamide, potassium content, to be pressed into internal diameter be that 8cm, wall thickness are that 3cm, base thickness are 4cm, highly are that 20cm, density are 330Kg/m to mould behind the poach ³Tubular alms bowl body, dry getting final product.

During use, dig pit in the coal gangue hill surface, nutritive cube is imbedded in the hole, sapling is implanted in the nutritive cube, with native populated space, watering the vegetable fiber nutritive cube fully soaked gets final product.
