Abstract
The present invention discloses gunite and a greening method for solidifying sand by covering layers which are formed from gunite. The gunite is slurry mainly prepared from the following components of the percentages by weight: 55 to 68% of water, 25 to 35% of crop stalk or industrial waste comprising certain fiber components, 2 to 10% of sticky yellow soil or laterite, 0.1 to 2% of plant water retention agent, 0.001 to 0.1% of adhesive, 0.001% of cotton or wool fiber, 0.01 to 1% of compound fertilizer, 0.0001 to 0.001% of trace element fertilizer, 0.2 to 6% of modified gypsum, 0.1 to 10% of cattle and sheep dung, 1 to 10% of wood saw dust, 0.0001 to 0.01% of phosphoric acid and 0.003 to 1% of seed. Prepared gunite is sprayed on the surfaces of deserts or soil, and a covering layer capable of solidifying and sealing sandy soil and germinating and growing plants is formed. The gunite is sprayed by a vehicular spray device, and the vehicular spray device is a spray device with a stirrer and a jet pump. The present invention has the advantages of high greening speed, good treatment effect, convenient construction, low cost, convenient popularization, etc.
Description
Technical field
The present invention relates to fix the sand, greening environment resist technology field, specifically a kind of whitewashing and whitewashing form the method that cover layer comes sand-fixing greening.
Technical background
At present, fix the sand to be divided into machinery in the world and fix the sand and chemical sand-fixing two big classes, machinery fixes the sand common having: manually do straw checkerboard barrier with grass and fix the sand; Vertical fence sand-protecting barrier fixes the sand; Nylon wire fence sand-protecting barrier fixes the sand; Manually fix the sand at upper berth, sand dune soil block, soil layer, stone cladding process.This kind mode is time-consuming, and persistence is poor, and difficulty of construction is big, and is little to the windproof ability.What chemical sand-fixing was common has: oil and by product pitch fix the sand; Cement layer fixes the sand; Waterglass fixes the sand; Macromolecule chemical material fixes the sand.This kind mode is constructed very inconvenient; limitation is big; most of chemical products contains toxicant, is difficult to degraded, contaminated environment at occurring in nature; some harmful substance permeates the ground with water in the water system; do not meet environmental protection requirement, oil product, by product apply influences the distribution of sand bed water source in the desert, and rainfall can not evenly be infiltrated below the sand bed; cause in the desert surface water potential drop low, cause psammophytes death.
Summary of the invention
The purpose of this invention is to provide a kind of whitewashing and whitewashing and form the method that cover layer comes sand-fixing greening, it has cheap, and sand-fixing greening speed is fast, and raw materials used compliance with environmental protection requirements is free from environmental pollution; The cover layer function admirable is executed in environment and the water level in the desert can be risen gradually, is beneficial to the growth of psammophytes; Sand-fixing greening reliability height, the length of holding time, easy construction, applied range, adaptability is strong, and large tracts of land is used and can be changed local sand and dust environment, is well suited for using in northern desert neutralizes the soil of other type.
The object of the present invention is achieved like this:
A kind ofly form the whitewashing that cover layer comes sand-fixing greening, it mainly is the slurry of being made by following component, by weight percentage:
Water 55-68%
Crop stalk 25-35%
Viscosity loess or laterite 2-10%
Liquid polypropylene acid sodium 0.1-2%
Sodium Polyacrylate and starch-grafted compound 0.001-0.1%
Staple 0.001%
Nitrogen, phosphorus, potassium three elements complex fertilizer 0.01-1%
The compound 0.0001-0.001% of iron, zinc, manganese
Super-fine anhydrous calcium sulphate 0.2-6%
Cattle and sheep excrement 0.1-10%
Wooden sawdust 1-10%
Phosphoric acid 0.001%
Seed kind 0.003-1%
Described seed kind is grass seeds, shrub seeds and all kinds of seeds.
Whitewashing of the present invention forms the method that cover layer comes sand-fixing greening, is that the whitewashing that will prepare is injected in desert or soil surface, and formation can be sealed the cover layer of sandy soil and plant germination, growth admittedly.
Spray and adopt vehicle-mounted spraying equipment, vehicle-mounted spraying equipment is the flusher that has agitator and jet pump.
Whitewashing manufacture craft among the present invention is: in the agitator of earlier water being packed into, crops bar of pulverizing or the industrial residue that contains certain fiber composition are added in the agitator, add liquid water-loss reducer, binding agent and staple, compound fertilizer, trace element fertilizer, cattle and sheep excrement, wooden sawdust, modified gypsum, phosphoric acid, the seed kind that mixes successively, the back form slurry stirs.
Slurry is very thick pastel, with the high-pressure injection device it is injected on desert or the soil surface, and the short time solidify to form a kind of cover layer that keeps slurry and sandy soil layer moisture and be fit to the germination of seed kind, growth.
Whitewashing among the present invention is the multicomponent mixture system, and system component adds selected foundation and is: the crop stalk of pulverizing plays the inserts effect; But liquid water-loss reducer water-absorbing-retaining; Cohesive soil reduces voidage, increases severe; Binding agent is united all components and is bondd with the sandy soil layer; Staple plays the skeleton anastomosis; Trace element fertilizer provides nutrient for plant growing; Modified gypsum plays freezing action, not free-flow after spraying to guarantee to whitewash; The cattle and sheep excrement provides organic nutrient to plant; Phosphoric acid is used for varying environment is regulated different pH values; Wooden sawdust can prolong the cover layer life-span, increases microorganism fungus kind.Multicomponent mixture is injected on the sandy soil surface and forms cover layer after mixing, and cover layer has special physical property, can absorb water rapidly during the sky rainfall, divides slowly release to supply with plant absorbing institute's suction during arid; Cover layer and sandy soil layer bond together, and be weather-proof, anti-drenching with rain, and sand fixation is played in anti-Japanese solarization rapidly; Cover layer helps the retaining of sandy soil laminar surface, can improve face of land water level in the sand bed at leisure; Cover layer can ensure surviving of new plant species and surviving of existing plant, forms a little microcirculqtory system, progressively changes local ecotope.
The present invention has the following advantages:
1, environmental protection is pollution-free: the raw material major part is a natural plants, and is all nontoxic, but executes in the Nature natural degradation in 3 years, becomes absorbable organic matter of plant and nutrient, do not pollute the environment.
2, greening speed is fast: behind the on-the-spot cover-seeding, can fix the sand, can afforest in two months.
3, regulation effect is good: behind the sand-fixing greening, water in the two weeks once, non-maintaining, cover layer can be preserved 3 years at occurring in nature, and the plant roots after surviving can be fixed sand.Use sand-fixing greening of the present invention, social benefit, economic benefit are very remarkable.
4, construction is comparatively convenient: can spend, be lower than on 80 meters high slopes and construct, solution slope problem big, precipitous and perilous, that manually can't afforest less than 60.
5, cost is low: the raw material of use is easy to get, and price is low, twice laid.
