Abstract
The invention discloses a plant culture medium for plant growth cement concrete, which is composed of following raw materials, by weight, 45-70 parts of papermaking sludge, 5-15 parts of high-water-absorption resin, 5-30 parts of vermiculite, 5-20 parts of peat soil, 1-5 parts of rice hull powder and 3-15 parts of a slow-release fertilizer. The plant culture medium is high in water absorption rate and is long in fertilizer efficiency durable time, and is reduced in alkali degree in gaps in the plant culture medium so that the plant culture medium is suitable for plant growth. The raw materials of the plant culture medium are easy to obtain and are low in cost. The plant culture medium is reduced in the alkali degree in gaps so that the plant culture medium is suitable for plant growth and can satisfy requirement on water and nutrients in normal growth. The plant growth cement concrete can protect side slopes and also afforest the side slopes, thereby protecting ecologic environment of the side slopes.
Description
Technical field
The invention belongs to environmental-friendly construction material field, particularly plant unboiled water cement concrete, specifically plant unboiled water cement concrete plant culture for one kind.
Background technology
Planting unboiled water cement concrete is by coarse aggregate surface parcel one deck grout of single particle size, the concrete with porous, macroporous structure piled up.Owing to planting unboiled water cement concrete, there is high open pore rate, higher physical strength, be therefore often used to fixed slope, prevent erosion.Compared with normal concrete bank protection technique, plant unboiled water cement concrete all right green side slope while protection side slope, repair slope ecological environment.
But it is fine and close to plant unboiled water cement concrete basal body structure, plant cannot directly grow planting on unboiled water cement concrete matrix, must fill and concrete surface cover plant growth matrix, be generally normal soil in concrete voids.Because the open pore rate of planting unboiled water cement concrete is 25 ~ 30%, therefore the plant growth medium inserted in space is less, the plant growth medium thickness that concrete surface covers also only has 1 ~ 2cm, is therefore difficult to using normal soil as plant growth medium meet the demand of plant normal growth to moisture, nutrient.In addition, it is higher to plant basicity (pH value) in unboiled water cement concrete space, is also not suitable for plant-growth.Therefore, plant applying of unboiled water cement concrete and be subject to serious restriction.
Summary of the invention
Above-mentionedly planting unboiled water cement concrete Problems existing to solve, the invention provides one kind and planting unboiled water cement concrete plant culture.The present invention is subacidity, water absorbent rate is high, the fertilizer efficiency time length is long, the basicity of planting in unboiled water cement concrete space can be reduced, make it suitable for plant growth, meet the demand of plant normal growth to moisture, nutrient simultaneously, avoid plant because of moisture, nutrient is not enough and dead, cause and plant the problem that unboiled water cement concrete cannot play the effect of afforesting and improving the ecological environment.
Technical scheme of the present invention is as follows: plant unboiled water cement concrete plant culture, be made up of the raw material of following weight part for one kind: paper mill sludge 45 ~ 70, High hydrophilous resin 5 ~ 15, vermiculite 5 ~ 30, peat soil 5 ~ 20, powdered rice hulls 1 ~ 5, slow-release fertilizer 3 ~ 15.
Plant a unboiled water cement concrete plant culture, preferably, be made up of the raw material of following weight part: paper mill sludge 45, High hydrophilous resin 15, vermiculite 9, peat soil 15, powdered rice hulls 1, slow-release fertilizer 15.
Preferably, described paper mill sludge to be saturated water absorption be 90 ~ 140% active sludge.
Preferably, the natural peat soil of described peat soil to be fineness be 100 mesh screen residues 25 ~ 55%.
Preferably, described slow-release fertilizer is be greater than the trimagnesium phosphate potassium type of 1 year and one or both mixing of trimagnesium phosphate ammonium type the fertilizer efficiency time length.
Preferably, described High hydrophilous resin water absorbent rate is 80 ~ 120 times, and fineness is 100 mesh screen residues 30 ~ 60%.
Preferably, described vermiculite fineness is 100 mesh screen residues 30 ~ 60%.
Preferably, described powdered rice hulls fineness is 100 mesh screen residues 30 ~ 65%.
The present invention obtains for mixed raw material with paper mill sludge, High hydrophilous resin, vermiculite, peat soil, powdered rice hulls, slow-release fertilizer.Paper mill sludge is paper industry byproduct, if by its simple landfill, not only waste resource, also can pollute.Active sludge is that the plant nutrient content such as a kind of organic matter and nitrogen, phosphorus, potassium is high, the paper mill sludge that heavy metal content is low, the suitable substrate material as plant culture.High hydrophilous resin is the high polymer containing hydrophilic radical, and water-intake rate is high, and water absorbent rate is 80 ~ 120 times, stable performance, is particularly suitable as organic water-holding agent of plant culture.Vermiculite is a kind of natural silicate minerals, and be laminate structure, water-intake rate is higher, and saturated water absorption is 240 ~ 300%, and water retention property is good, is good inorganic water-holding agent, and all right chessom of vermiculite, improve the ventilation property of plant culture.Preferred natural peat soil is organic soil, not only water-intake rate is high for it, and itself be subacidity, potential of hydrogen (pH value) is 5.5 ~ 6.5, the basicity of planting in unboiled water cement concrete space can be reduced, further, containing the organic matter of 15 ~ 50% in natural peat soil, in organic matter degradation process, nutrient can be provided for plant again.Powdered rice hulls is levigate obtained by agriculture byproduct rice husk, and effectively can improve the water-retaining capacity of plant culture, improve the ventilation property of plant culture, powdered rice hulls potassium content is high simultaneously, can provide required nutrient in degradation process of rotting for plant.Trimagnesium phosphate potassium type, trimagnesium phosphate ammonium type slow-release fertilizer excellent performance, the fertilizer efficiency time length is greater than 1 year, sustainablely provides fertilizer for plant.
The invention has the beneficial effects as follows:
(1) water absorbent rate is high; The water of adsorbable own wt 10 ~ 17 times.
(2) the fertilizer efficiency time length is long; The fertilizer efficiency time length can reach 12 ~ 16 months.
(3) basicity of planting in unboiled water cement concrete space can be reduced, make it suitable for plant growth.
(4) raw material is easy to get, with low cost.
The present invention can reduce the basicity of planting in unboiled water cement concrete space; make it suitable for plant growth; meet the demand of plant normal growth to moisture, nutrient simultaneously, make to plant unboiled water cement concrete all right green side slope while protection side slope, edge protection slope ecology environment.
