Abstract

The invention relates to a manufacturing method for a flame-retardant organic mulch for landscapes and greenbelts. The method comprises the following steps: separately collecting landscape wastes such as tree branches, tree leaves, stems and leaves of flowers and plants generated in the greening and maintaining process; crushing the tree branches and processing the tree branches into particles about 1.5-7.0 cm in length; crushing the tree leaves and the stems and leaves of flowers and plants into fine particles about smaller than 0.5 cm in diameter; then adding water, a fermentative strain and a fermentation catalysis substance, neatening the materials in piles, fermenting for 30-45 days and then paving the materials in the greenbelts; finally spraying a water-soluble flame-retardant agent to the surface of the organic mulch. According to the method, the cyclic utilization of the landscape wastes can be implemented; the rising dust is reduced; the water retention capacity of the landscapes is improved; the soil humidity is retained; the hardening of the soil is avoided; the growth of weeds is inhibited; the soil fertility is enhanced; the greenbelt landscape effect is improved; the safety of the organic mulch is improved.

Description

The manufacture method of the fire-retardant organic mat of a kind of Garden Greenland
Technical field
The present invention relates to afforestation field, be specifically related to the manufacture method of the fire-retardant organic mat of a kind of Garden Greenland.
Background technology
Urban green space system is large by interference from human factor, the ecosystem is comparatively fragile, the dry branches and fallen leaves of cities and towns trees or management discarded object etc. are often used as refuse cleaning by people and are even incinerated, soil can not be returned carry out material recycle as in natural forest, in addition human activity is frequent, causes city artificial soil of greenbelt consolidation, water-holding capacity is low, poor aeration, the content of organic matter are few, fertility constantly declines.Organically cover material is exactly revert in urban green space by the greening discarded object produced in Urban Landscape Construction, production, maintenance processes after processing, realizes the cycling and reutilization of resource.But, because covering is the crushed material of plant, in application process, there is certain disaster hidden-trouble.So, by the invention of this project, ecological, saving, safe construction of city afforestation and sustainable development are significant.
Summary of the invention
Object of the present invention, is to provide the manufacture method of the fire-retardant organic mat of a kind of Garden Greenland, is recycled by afforestation discarded object, and improves its safety in application process, reduces greening cost.
The technical scheme adopted is:
A manufacture method for the fire-retardant organic mat of Garden Greenland, comprises the steps:
1, material collection:
By the garden waste separate collection such as branch, leaf, flowers and plants cauline leaf of below diameter 30cm produced in virescence maintenance process, branch is classified separately, leaf and flowers and plants cauline leaf merge sort, removes the foreign material such as iron wire, stone, plastics and the stub be mixed into, in order to avoid damage machine, impact fermentation.
2, raw material processing:
By sorted raw material, branch adopts a machine of cutting to pulverize and is processed into the particle that major diameter is 1.5-7.0cm, and leaf and flowers and plants cauline leaf etc. are machined to the fine particle thing of below diameter 0.5cm by crushed stalk, pulverizes latter two particle mixed storage, for subsequent use;
3, fermenting raw materials:
Step 2 raw materials is added fermented bacterium and fermentation breaks compound matter, fermented bacterium is Gymboree, and fermentation catalytic specie is chicken manure and urea, and addition is every 1-2 ton or 5m 3add Gymboree 1-1.2kg in raw material, chicken manure 25-30kg and urea 12.5-15kg, adjustment C/N ratio is 30:1-1.5; Be placed in the greenhouse of spatial altitude>=4m, on concrete floor, arrangement piles stack, high 1.3-2m, water to saturation moisture capacity, push the particle of heap body upper strata 50cm thickness after 2-3 days aside, then spray water once to saturation moisture capacity, after 2 days, the particle pushed aside is covered on initial pile body again, ferments; Yeast phase is 30-45 days, keeps ventilating and heap body water content between yeast phase;
Adopt secondary ventilation, the regular turning of mode that artificial and forklift combines, regulate heap temperature to remain on about 55-65 DEG C, turning in every two weeks of general season in spring and autumn once, turning in every 10 days of summer once, turning three times altogether; Each turning optionally adds water, and third time turning does not add water, or adds water on a small quantity;
4, green cover:
Be layed in greenery patches by the organic mat that step (3) processed, cladding thickness 5-8cm, blanket edge and trees base portion keep the circular distance of 20-30cm;
5, fire retardant is sprayed:
Water miscible fire retardant is sprayed at organic mat surface, raw materials used is the ammonium polyphosphate of environment-friendly type, solid ammonium polyphosphate and water is mixed into solution, is sprayed on organic mat surface, make penetration depth reach 3-5cm, the mass ratio of ammonium polyphosphate and water is 15-20:100.
Fire-retardant organic mat of the present invention can be used for the covering of bare soil in urban green space, specifically comprise: tree well, tree pond filler, there is the tree pond of tree pond cover plate can fill this organic mat between soil and cover plate, flower bed, presbyopic glasses soil covering materials, sylvan life greenery patches, dividing island, roundabout greenery patches, greenery patches, curbside, with lawn collocation etc.It should be noted that damaed cordition lower than the height of border, greenery patches thing, should be made regular check in the surface of covering when applying, adding organic mat in good time and spraying fire retardant.
Beneficial effect of the present invention:
The fire-retardant organic mat of Garden Greenland of the present invention can realize recycling of garden garbage, reduce airborne dust, increase greenery patches reservoir storage, keep soil moisture, keep soil from packing together, suppress weed growth, strengthen soil fertility, promote green landscape effect and the safety of machine covering, can be widely used in construction of city afforestation and maintenance management.
