CN102153403A - High-order pellet plant growth matrix - Google Patents

Abstract

The invention discloses a high-order pellet plant growth matrix which comprises the following components in parts by weight: 1100-1500 parts of natural fiber, 900-1000 parts of humus, 30-45 parts of high-order pellet agent, 30-40 parts of natural clay stabilizer, 140-160 parts of seed, 100-150 parts of fertilizer and 20-35 parts of perlite. The perlite is added into the plant growth matrix, and thus the high-order pellet plant growth matrix has the characteristic of light weight during saturated water absorption, the load problem of slope structure is effectively solved, and the matrix can be prevented from falling because of the overweight of blasting and spraying materials; the growth and the development of the virtual root system of plant can be greatly accelerated according to the characteristics of product porosity, and trees can be favourably fixed; and meanwhile, damages to architectural structure by the main roots of the trees can be overcome.

Description

High order granule plant growth medium

Technical field

The invention belongs to plant growth medium, be specifically related to a kind of high order granule plant growth medium that can be used for spraying and seeding afforesting.

Background technology

Because a variety of causes causes a large amount of sloping bodies exposed, environment is formed destroy at present, also influence attractive in appearance simultaneously.In addition, also can form suspended particulate, cause that water ground runs off etc. and be unfavorable for the consequence of environment protection.Suspended particulate in the atmosphere can have a negative impact to HUMAN HEALTH.Contain a large amount of pollutents in the atmosphere, not only influence meteorological factors such as sunshine, form acid rain and influence plant-growth, and directly be detrimental to health.Our country runs off on present water ground very serious, and the sediment concentration in the big river in now main great river obviously increases, and this is that the ecosystem is degenerated on the one hand, and is also single relevant with minimizing of green plants area and kind on the other hand.

Because it is few fertile that soil is located to lack in exposed massif, hillside fields etc., plant is difficult to growth, carries out very difficulty of greening vegetation in these places.In recent years, risen a kind of high order granule spraying and seeding afforesting construction method at exposed sloping body greening, at the comparatively difficult surface of greenings such as rock, hard soil, sandy soil, poor and barren land, acid soil, arid tract, seashore dykes and dams, adopt the earth, the fertilizer that are fit to plant-growth to add plant seed and form mixture, and add other necessary materials, adopt mode such as sow grass seeds by duster to form the growth basal disc of the most suitable plant-growth.This artificial soil has the needed optimal high order crumb structure of agricultural and greening field, and existing water-retentivity has water-permeable, ventilation property again, is suitable for plant-growth, and can resist weathering and wind erosion, prevents erosion.

High order granule plant growth medium of the prior art, the general materials such as fiber, soil ulmin, the agent of high order granule, the agent of pure natural clay, seed, fertilizer that adopt mix, have better water retention performance and higher sticking power, be fit to plant-growth, can form vegetation in a short time.But because this growth matrix water content is big, viscosity is big, sow grass seeds by duster on the slope after, because of weight causes landing greatly easily, cause vegetation inhomogeneous, even need construction again.Owing to contain gelatin substance in the matrix, the ventilation property of matrix is relatively poor in addition, and a lot of plant seeds can't germinating growth, and bud ratio is low, causes the greening cost to improve.

Summary of the invention

In order to overcome the problems referred to above that the prior art field exists, the objective of the invention is to, a kind of good permeability, water-retentivity is strong, density is lower high order granule plant growth medium are provided.

High order granule plant growth medium provided by the invention, the weight ratio of its component are natural fiber 1100-1500 part, soil ulmin 900-1000 part, agent 30-45 part, natural clay 30-40 part, seed 140-160 part, fertilizer 100-150 part, perlite 20-35 part.During use, above-mentioned matrix is covered massif, the surface, hillside fields of desiring to afforest in the mode of sowing grass seeds by duster, the soil on massif or surface, hillside fields combines with this matrix, and good plant growth environment is provided, and realizes the greening purpose.

Natural fiber: main component is a plant cellulose, is called native cellulose fibre again.It is the fiber of locating to obtain by the seed of plant, fruit, stem, leaf etc.Have ventilation property, degradable, pollution-free, the characteristics that can be converted into nutritive substance.

Perlite: the gardening gardens are to separate through perlite fine screen choosing to form with the greening pearlstone, and its particle reaches 2.5-7mm.Its granule interior is a polynuclear plane, and is nontoxic, tasteless, be stale-proof, and do not fire acid and alkali-resistance.Be used for gardens, on the flowers, protect fertilizer, water conservation, aseptic, good permeability.

Granule agent: be a kind of water-soluble organic class soil conditioner that a kind of high molecular weight polyacrylamide (PAM) is polymerized, because of it has stronger sedimentation and flocculation soil particle, in soil, form good crumb structure, therefore constitute the carrier of antiscour, antiseep.

When sowing grass seeds by duster construction, may further comprise the steps:

The first step, the preparation plant growth medium according to aforementioned proportion, is prepared burden according to construction area, after batching is finished, in order to sowing grass seeds by duster construction;

In second step, lay wire netting: behind the float stone on cleaning is domatic, danger stone and the rubbish weeds, wire netting is launched at the bottom of by sloping Xiang Zhipo, draw to be hung on domaticly, the top is fixed with the Bower Anchor firmware;

The 3rd step, set anchoring piece: anchoring piece sets according to domatic form for Bower Anchor firmware and time anchoring piece, and it is domatic that wire netting is firmly fixed on, the usage quantity of Bower Anchor firmware is no less than 60 for per 100 square metres on the anchoring piece consumption, and inferior anchoring piece usage quantity is no less than 180 for per 100 square metres;

The 4th step, the plant growth medium of sowing grass seeds by duster, carry out in the front of sowing grass seeds by duster, and avoids direct projection, and the thickness of sowing grass seeds by duster should be even as far as possible, but emphasis should be arranged, and gush in good place planting carded sliver spare, badly locates to spray thicker planting carded sliver spare.

High order granule plant growth medium provided by the invention, its beneficial effect is, in plant growth medium, add perlite, has following technique effect: 1, weight 450-600kg/m3 during saturated suction, far below the about 1800kg/m3 of general soil, efficiently solve the Load Problems of hillside fields structure, the material of avoiding sowing grass seeds by duster is overweight and peel off; 2, coefficient of permeability is 200mm/hr, can effectively avoid alluvial harm; 3, effectively water ratio is up to 45%, and rainwater can effectively dam; 4,100% pure organic culture substrate, stable physical-chemical indexes, the permanent cultivation of plant need not soil removal and replacement; 5, the porousness of product has promoted that greatly the imaginary root of plant is a g and D, and trees are had fabulous fixed action, has overcome the destruction of trees main root to building structure simultaneously; 6, clean free from extraneous odour, easy construction, make things convenient for maintenance.
