Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of and has better storage capacity, can guarantee that having of side slope nursing effect irrigated and the karst area slope nursing structure of water retaining function, can overcome the deficiencies in the prior art.
The technical solution of the utility model: the karst area slope nursing structure with water retention property, it comprises the shrub slope protection region of karst, on shrub slope protection region, be equipped with water-keeping material, on water-keeping material, be provided with and plant generating apparatus, be provided with artificial soil and vegetable seeds setting on the shrub slope protection region of planting generating apparatus, between shrub slope protection region and water-keeping material, be provided with drip irrigation appliance.。
The above-mentioned karst area slope nursing structure with water retention property is above water-keeping material, to be provided with geonet or wire lath.
The aforesaid karst area slope nursing structure with water retention property is that described water-keeping material is sponge or rock wool.
It is described that to plant generating apparatus be plate from plant wastes or plant raw lattice.
Compared with the prior art, the utility model is to be " 2009203029561 " in the patent No., and patent name improves on the use basis for " vegetation member for slope face protection of side slope in karst region ".The present invention finds in the use procedure of above-mentioned patent, plant the stream that can well prevent artificial soil that arranges of raw member, but be subject to the impact of solar term and weather, the required moisture of germination cannot well guarantee, cause the germinating time of plant in side slope nursing process not unify, in the same period, the region of emerging of plant is sheet, and effect is checked and accepted in the inhomogeneous impact of afforested areas; Some plant germinateing soon often can the death because of lack of water simultaneously.For reply the problems referred to above, the utility model is laid water-keeping material on shrub slope protection in karst area region domatic, and then the generating apparatus of planting that can stop artificial soil and seed landing is set above water-keeping material; By water-keeping material with plant generating apparatus fixing after, adopt spray seeding car to being fixed with shrub slope protection in karst area area spray artificial soil and the vegetable seeds thereof of planting generating apparatus, the laying of water-keeping material just can solve the karst area fast problem that seeps water to a great extent, guarantee germination and the growth of plant, and can make the growing way of plant more unified, afforestation effect significantly promotes; Through applicant's test, the laying of water-keeping material can increase plant survival rate 80% under equal environment, and soil moisture content slows down 3-5 days without water-keeping material region relatively.Water-keeping material is arranged on to geonet or wire lath below, and geonet or wire lath can well be fixed and can not affect and plant the fixing of generating apparatus; Water-keeping material is selected sponge or rock wool, and sponge or rock wool have advantages of that cost is low, and the waste and old product that preferably reclaim, can further reduce costs.
Before laying water-keeping material, on need nursing is domatic, lay irrigation system, in the later stage, need like this season of moisturizing, will form below water supplementing method, impel root system of plant to grow downwards, the in the situation that of identical rate of water make-up, reduce moisture evaporation, reduce consumption and the fortune water cost of water simultaneously; And the domatic top layer that drip irrigation can not form at the destruction initial stage, can better reach protection effect.
