Abstract

A kind of waterfront or falling zone rock matter bank slope ditch and dispose nutrient bag structure and ecological restoring method, including the following contents: being excavated in waterfront or falling zone rock matter bank slope and form U-shaped ditch, the U-shaped ditch forms an angle with slope surface contour shape, and along slope surface layered arrangement, the lower end of every U-shaped ditch connects with gutter;Nutrient bag is placed in U-shaped ditch, the nutrient bag bag body is double-layer structure, and active carbon or bamboo Charcoal Adsorption agent are clipped between bilayer, filled with plantation substrate in bag, and pokes nutrient bag plantation herbaceous plant.Bag body provided by the invention and plantation substrate formula, can adsorb the nutriment in Nutrition Soil, effectively prevent water pollution;The way that nutrient bag is placed in the U-shaped ditch of design not only improves soil conservation, in turn avoids the harm impregnated when raining.The present invention is that waterfront or falling zone rock matter bank create sustainable animals and plants habitat, is had great importance to waterfront or falling zone rock matter bank slope restoration of the ecosystem.

Description

Waterfront or falling zone rock matter bank slope ditch and dispose the structure and restoration of the ecosystem of nutrient bag Method
Technical field
The invention belongs to waterfront or falling zone restoration of the ecosystem fields, and in particular to waterfront or falling zone rock matter bank slope trench digging are simultaneously Dispose the ecological restoring method of nutrient bag.
Background technique
Waterfront or falling zone rock matter bank slope land occupation condition are poor, and the gradient is big, lacks the soil for plant growth.Rock matter bank slope Although there may be sedimentation in the phase of flooding, to be often difficult to grow by rain erosion and wave cut, silt in the water outlet phase Phase saves.By the investigation discovery to Sanxia area, there is the plant based on Bermuda grass, Liao's grass and Siberian cocklebur in the falling zone of soil-slope Object group, even if the falling zone exposed the surface still is able to cover side slope quickly after water logging some months, the covering situation of vegetation is good The falling zone Yu Yanzhi.Therefore, it in waterfront or falling zone rock matter bank slope, tries every possible means that soil can be kept for a long time, is restoration of the ecosystem Key.
For common rock matter bank slope, people generally use platform method of floaing and afforest, and plant climbing plant;For being flooded Riverbank not, people are afforested using floating bed method, planting aquatic plants.But alternately the waterfront of control or falling zone are green to land and water Change, using floaing Tai Fa or floating bed method or other methods have that application is undesirable.Although Tai Fa can be in rock matter bank using floaing The soil of plant growth is provided on slope, but the plantation nutrient matrix accommodated in the platform planting groove that floats contains more organic matter, in water Enter water body when flooding, causes water pollution;Though using floating bed method that can provide growing environment by kickboard for plant, the battalion contained It is fixed difficult to support matrix water body easy to pollute, floatation unit.Above two method higher cost, is unfavorable for being widely applied.
For this reason, it may be necessary to the restoration of the ecosystem of waterfront or falling zone rock matter bank slope is carried out using new more economical method, one Aspect solves the problems, such as that soil is kept for a long time, on the other hand, solves substrate early stage to water pollution issue.
Summary of the invention
It ditches the purpose of the present invention is to provide a kind of waterfront or falling zone rock matter bank slope and the ecology of nutrient bag is disposed to repair Compound method can not provide plant growing condition, planting matrix to alleviate waterfront or the presence of falling zone rock matter bank slope ecological reestablishment The problem of material polluted-water.
In order to solve the above technical problems, technical solution provided by the invention is: waterfront or falling zone rock matter bank slope trench digging And the structure of nutrient bag is disposed, including U-shaped ditch, nutrient bag, gutter, there are U-shaped ditch, U in waterfront or falling zone rock matter bank slope Shape ditch is strip structure, and U-shaped ditch trend forms an angle with slope surface contour shape, and arranges in slope surface higher slice, and every U-shaped The lower end of ditch connects with gutter;Nutrient bag is placed in every U-shaped ditch, the nutrient bag bag body uses double-layer structure, Active carbon or bamboo Charcoal Adsorption agent are accompanied between bilayer, plantation substrate is filled in bag, and plant grows from nutrient bag.
Distance L is 1.5-2.5m between the adjacent U-shaped ditch, and the depth H of every U-shaped ditch is 15-25cm, width C 10- 30 cm;Distance M is 6-12 m between adjacent row ditch.
The nutrient bag bag body is made of non-woven fabrics, nonwoven thickness 0.5-1.0mm, and Unit Weight is 50-90 g/ m2
The active carbon or bamboo Charcoal Adsorption agent particle are 3-5 mm.
The active carbon or bamboo Charcoal Adsorption agent are substituted with bentonite.
The plantation substrate is formulated using loam, humus, plant ash, treated diatomite;Plant substrate Formula be (by volume): loam 80%, humus 10%, plant ash 2%, treated diatomite 8%;The processing of diatomite Method is dried after using concentration to impregnate for 7%-8% potassium dihydrogen phosphate aqueous solution.
The treated diatomite is replaced with treated zeolite or float stone;The processing method of zeolite or float stone is adopted It is to be dried after 7%-8% potassium dihydrogen phosphate aqueous solution impregnates with concentration.
The waterfront or falling zone rock matter bank slope ditches and disposes the construction method of nutrient bag structure, includes following step It is rapid:
(1) nutrient bag is made, nutrient bag is punctured and plants the Bermuda grass of suitable southern area growth, Liao's grass, Siberian cocklebur, in greenhouse Or nursery in greenhouse.
(2) selection dry season constructs, and mucking slope surface rubble, surface soil, sundries eliminate safe hidden trouble.
(3) in rock slope surveying and locating, the position of every U-shaped ditch and the trend in gutter are determined.
(4) rock slope is excavated, is trimmed to U-shaped.
(5) nutrient bag is placed in U-shaped ditch, sunshade net and regular sprinkling maintenance in covering.
In conjunction with above technical scheme, the beneficial effect that the present invention reaches is:
First, the substrate loaded using U-shaped ditch and bag body can keep substrate, and can deposit some silts, foundation can be held for a long time Continuous habitat;Second, there is diatomite in substrate formula, bag body is provided with active carbon or bamboo charcoal, can effectively mitigate substrate nutrition Substance is lost, and mitigates water pollution;Third, structure is simple, at low cost;4th, it can first carry out greenhouse or nurse young plants in hothouses, realization is When fast greening.
