Abstract
The present invention discloses a local controlled afforestation technology in high water-level halomorphic soil area; the technology comprises that 1. the former soil layer is removed; 2. a cushion is laid; 3. a waterproof layer is laid; an infiltration pipe is laid; 4. a trickling layer is laid; 6. the soil is changed and the trickling layer is filled with coated soil which is fit for planting; 7. a guard wall is built; 8. trees are planted on the soil for afforestation and enough fresh water is irrigated in time. With the integral separation and local controlled microcirculatory system in the afforestaton area, the present invention can complete the construction of local suitable environment for afforestation and overcome the defects that with traditional afforestation technology, the salt and water drainage effect is bad and the afforestation sight can not be kept long in the high water-level halomorphic soil area; the present invention can obviously promote the afforestation level and enlarge the afforestation range.
Description
Affiliated technical field
The present invention relates to high water level saline soil urban landscaping technology.
Background technology
In recent years along with coastal cities, especially the border on the sea fast development of port city, to environmental greening, beautify, the demand of brightening is very urgent, these areas are in terrestiral ecosystem system and aquatic ecosystem intersection, freshwater resources scarcity, serious, the saline groundwater water level height of salination, these unfavorable factors are seriously restricting this area's afforestation work.Traditional afforestation project in these areas mainly concentrates on the aspects such as soil melioration, sub-district salt discharge and subenvironment construction to growing area at present, these traditional measures are better in the regional effect of phreatic low (below 1.5 meters), but draining salt discharge weak effect, greening view efficiency time weak point and the engineering high disadvantage of rate repeatedly often appears in the effect in higher level (more than 1.0 meters) saline soil district, become the indeterminable difficult problem of these conventional arts, perplex always and limiting the greening level and the benefit of locality.
Summary of the invention
The purpose of this invention is to provide a kind of hold imitate length, easy construction, maintenance is simple, cost is low, the high water level saline soil district greening technique of applied range, utilize green belt overall isolation, Region control microcirculqtory system, finish the construction of the local suitable environment in green belt, disadvantages such as traditional greening technique uses the salt discharge drainage effect of back appearance poor in high water level (more than 1.0 meters) saline soil district, the greening view retention time is short have been overcome, can significantly improve the greening level, enlarge the greening scope.
The high-water level halomorphic soil region selective controlling and greening technique scheme that the present technique invention is provided is as follows:
1, removes former soil layer: will treat according to different green plants that the green belt should not soil be got and cut out 80-120cm;
2, setting cushion: bottom 5-10cm soil layer quicklime mixing, compacting, the leveling of 10-20%;
3, lay water barrier: all use polyvinyl chloride film (0.2-0.3mm) to lay water barrier with the bottom all around;
4, lay soakaway trench: rationally distribute by position, green belt and direction and lay Φ 20cm PVC palm soakaway trench, generally at 3-5 ‰, spacing is no more than 5m to the water permeating pipeline gradient, and soakaway trench finally imports collecting basin and connects pumping equipment;
5, lay the trickle layer: the stone fragment (or river sand, boiler ash sediment) of laying 15-20cm on the water barrier is for isolating the trickle layer;
6, soil removal and replacement: fill up the soil moved in to improve the original of to plant on the trickle layer;
7, will build the protection wall of 10～20cm above ground level around the face of land, green belt, prevent that surface water from flowing in the green belt;
8, greening is planted, and in time waters the suitable fresh water of foot.
The zone that the present invention suits: the subterranean water level height, winter the underground water hydrostatic level about 1.0m, rainy season subterranean water level about 0.6m, soil salt content is generally more than 20 ‰, the degree of mineralization of ground water is more than 5 ‰.
The material that the present invention uses:
1, soil moved in to improve the original: suitable soil
2, isolate bed course: quicklime
3, trickle layer: stone fragment, river sand, boiler ash sediment
4, water barrier: polyvinyl chloride film (0.2-0.3mm)
5, the salt pipe is drenched in draining: PVC palm salt discharge pipe (Φ 10-20cm)
Know-why of the present invention:
1, used from the basis and should plant soil and replace the unsuitable soil in former green belt, for greening seedling provides the suitable soil body;
2, the various suitable factor of having built green plants from the subenvironment simulation:
I. afforest soil body environment bottom and all laid water barrier all around, prevented the immersion of underground moisture and salinity fully, guaranteed the independence of subenvironment;
II. lay the trickle layer on the water barrier, guaranteed the unobstructed of bottom discharge salt discharge pipe, made in the greening soil body excessive moisture in time enter draining and drench the salt facility, thereby prevented the waterlogging of subenvironment and the accumulation of salt water, guaranteed the gas permeability of the soil body;
The application of III.PVC palm salt discharge pipeline makes in the greening soil body redundant moisture in time drain, in case the soil body has salt damage to take place, also can guarantee the persistence of greening in time by pouring into the fresh water desalinization of soil by flooding or leaching;
IV. in time water the suitable fresh water of foot after greening is planted, solved the phreatic negative pressure problem of water barrier, prevented to occur excessive pressure differential between soil body subenvironment and the beneath water level, guaranteed the safety of water barrier;
V. lay quicklime mixing bed course under the water barrier, made PVC palm salt discharge pipeline and water barrier reduce the damage that causes because of the base portion distortion, prolonged the service life of subenvironment.
3, the application of water barrier and salt discharge pipe makes this facility itself just possess the function of desalinization of soil by flooding or leaching salt discharge, can reduce the soil removal and replacement cost greatly to certain saline soil.
The technology of the present invention innovation and advantage:
1, original salt discharge pipe is displaced downwardly to more than salt deposit from separation layer, makes underground water can not enter drainage pipeline, reduced the salt discharge load;
2, by using water barrier, the greening soil body is isolated with the unsuitable soil body fully, green plants can not contact with salt-affected soil, thereby has improved the life-span and the safety of greening seedling;
3, this technological invention is significantly improved the greening lasting effect in high water level saline soil district;
4, the not only suitable high water level saline soil district of this technology is suitable for too to other afforestation project than low water level, and range of application is wider;
5, this technology to certain salt-affected soil can directly utilize fresh water repeatedly the desalinization of soil by flooding or leaching improve, again in conjunction with applying organic manure, play and reduce soil removal and replacement amount, the effect that reduces cost.
6, it is better that this technological invention in use is used effects such as some biological control measures and agricultural measures.
The concrete implementation result of the present invention:
Since two thousand two, this technology many places effect in the afforestation project of Harbor, Huanghua, Hebei province is obvious, compares with the conventional art measure, and its persistence is effectively verified.Use the contrast engineering of these technical measures and conventional art measure the same period, shown new technology engineering green plants well-grown, and the nursery stock of conventional art measure has presented the large-area degeneration and the phenomena of mortality.
Below in conjunction with drawings and Examples the present invention is described in further detail.
