The present invention is suitable for slopes the gradient of which is smaller than 90 DEG, and is especially suitable for the vegetation protection of acidic or strong acidic soil slopes.
Description
Technical field
The present invention relates to a kind of vegetation plantation base material, particularly a kind of greening base material of rock slope biological protection.
Background technology
At present, the biological protection and greening base material of rock slope adopts the alien earth sparging technology more, promptly sprays the soil that one deck is fit to plant growing with high-tension apparatus on exposed rock slope.Because rock slope mostly is half weathering or unweathered rock mass, and the soil horizon thickness of being sowed grass seeds by duster is limited, need to have in this soil moved in to improve the original that just requires to sow grass seeds by duster for necessary organic matter of plant long term growth and nutrient component.And lack necessary organic matter of plant growing and nutrient component in the normal soil, can soil ph (pH value) survive plant bigger influence is also arranged simultaneously, therefore can the soil moved in to improve the original of being sowed grass seeds by duster satisfy the needs of plant long term growth, key is should allocate in the soil moved in to improve the original the necessary various nutriments of plant growing, promptly adds suitable greening base material.Require to provide the plant long term growth needed nutrient component as biological protection and greening base material, have suitable pH value, simultaneously stronger scour resistance will be arranged, and can with the vegetation acting in conjunction, prevent domatic weathering off.
Yunnan is located in the laterite plateau, has particular climate and soil condition, and its distinctive red soil granule structure is poor, easily produces and hardens.And the red soil pH value is lower, mostly is acidity or strongly acidic soil, and soil property is barren.Lack the greening base material be suitable for the Yunnan particular surroundings in the prior art, can't do to regulate effectively to soil physico-chemical property, and the binding material amount of adding is too much, make the soil phenomenon that occurs hardening easily, be unfavorable for plant growing.Simultaneously, the content of organic matter is generally lower in the existing base material, is difficult to satisfy the basic need of mountain area, plateau plant growing.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of content of organic matter to enrich, have good cohesiveness and moisture capacity, effective adjustment of acidity P in soil H value, satisfy the rock slope biological protection and greening base material of plant growing needs.
Rock slope biological protection and greening base material of the present invention is adjusted modifying agent, cellulose, water-loss reducer and binding agent by brown coal, bio-bacterial manure, base material and is formed, the cooperation ratio of each component is by weight: brown coal 65～80, bio-bacterial manure 0.2～0.35, base material is adjusted modifying agent 2～5, fiber 20～35, water-loss reducer 0.02～0.05, binding agent 0.02～0.05.It is blending ingredients that wherein said base material is adjusted modifying agent, and its each component is counted by weight: superphosphate 2～3, potassium nitrate 14～18, composite fertilizer 14～18, ferrous sulfate 0.15～0.45, zinc sulphate 1～2, urea 14～18.
Rock slope biological protection and greening base material of the present invention also comprises the mixed plant seed.
In said components, brown coal are rich in organic matter, also contain the necessary nutritive elements of plant growing (seeing Table 1) such as nitrogen, phosphorus, iron, zinc simultaneously, can make up the environment of suitable plant growing, for plant is supplied with nutriment; Has the certain moisture water retention simultaneously, the required moisture of self-restraint plant growing.Cellulosic effect is the mutual bridge joint of base material is got up to form the integral body of organic structure, generally adopts half wooden or wood materials such as bagasse, stalk, cornstalk, straw, through natural air drying, pulverize after as additive.Base material is adjusted the physicochemical property that modifying agent can effectively be regulated base material, and simultaneously, the nitrogen that wherein is rich in, phosphorus, potash fertilizer can strengthen the fertility of base material, promotes the growth of plant.The composite bacteria bio-bacterial manure is selected in bio-bacterial manure for use; Binding agent is neutral high polymer binder.Can select for use Bei Jinghan to try hard to keep adhesive PAM-2100 (powder), PAM-A30 (powder) or PAM-3000 (powder) that the science and trade center produces, linear function high molecular polymer content 100% (molecular weight 1,500 ten thousand wherein, biological stability is strong, but arbitrary proportion is water-soluble), 4-6 week in service life.Utilize the cohesiveness of bio-bacterial manure self, add again after neutral high polymer binder mixes, make base material form the required best granular structure of plant growing, have good erosion resistibility simultaneously.Water-loss reducer is a polyacrylamide type water-loss reducer, can select for use Bei Jinghan to try hard to keep PR3005 or PR3005K2 or PR3005KM type polyacrylamide type water-loss reducer that the science and trade center produces, acrylamide and acrylic acid salt crosslinking copolymerization thing content 100% wherein, service life 2-4, its effect is to form at the root system of plant layer to be evenly distributed, and has the crystal reservoir of good water storage, improve the germination rate of plant seed, improve soil ventilation simultaneously, increase soil activation, reduce soil compaction.
Increase soil activation, reduce soil compaction.
As source of organic matter, organic matter that it is rich in and nutritive element can fully satisfy the needs of plant growing to rock slope biological protection and greening base material of the present invention with the distinctive brown coal in Yunnan.At the characteristics of high-level laterite, select for use special base material to adjust modifying agent, the acid-base value of base material is carried out the adjusting of appropriateness.Its raw material is easy to get, technology is simple, environment friendly and pollution-free, be applicable to the side slopes of the gradient less than 90 degree, be specially adapted to the vegetative protection of acidity or highly acid soil-slope.
The chemical composition of table 1 brown coal
