The utility model discloses an ecological restoration system for saline-alkali land, which comprises a salt-isolating soil foundation and a plurality of modular turfs. The salt-isolating soil foundation comprises a rubble layer, a geotextile layer, a crushed stone layer, a polyethylene layer and a polyethylene layer which are laid sequentially from bottom to top. The plastic film layer and straw layer are laid on the original saline-alkali ground with a saline-separated soil foundation; the modular turf includes four or six stone layers, medium stone layers, and fine stone sand layers filled in sequence from bottom to top, and the fine stone sand layer is covered with glass fiber cloth. , The top of the glass fiber cloth is filled with a guest soil layer, the guest soil layer is mixed with halophilic microbial fertilizer, and the guest soil layer is pre-planted with saline-alkali tolerant grass. The utility model can greatly reduce the migration of salt and the generation of returning salt, improve the effect of salt discharge, and at the same time, the use of modular turf can realize rapid planting, avoiding the problem that the plants directly sown in the saline-alkali land are difficult to survive, and the mixed soil in the foreign soil is difficult to survive. The halophilic microbial fertilizer gradually turns ineffective soil into mature soil where plants can grow.
Description
Technical Field
The utility model particularly relates to an ecological restoration system for saline-alkali soil.
Background
China is wide in territory, but the number of suitable land for cultivation is small because mountain lands, hills and plateaus account for 69 percent of the national area. And the percentage of the area of the saline-alkali soil to the area of the national soil is also arranged in the front internationally. The aggravation of the salinization degree of the soil leads to the incapability of survival of a plurality of plants, and the agricultural development and the ecological civilization construction of China are seriously influenced.
In the process of ecological restoration of saline-alkali soil, salt invasion is a serious problem, and salt in peripheral and bottom saline-alkali soil easily invades planting soil. At present, an isolation layer is generally arranged by adopting a method of paving broken stones, and saline-alkali tolerant plants are planted on the isolation layer, so that the problems that the isolation effect is poor, salt is easily transferred to planting soil in a flood irrigation process in heavy rainy days, and the problems that the germination rate of saline-alkali tolerant plant seeds is low and seedlings are difficult to survive exist.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art, and provides an ecological restoration system for saline-alkali soil, which comprises a salt-separating soil base and a plurality of modular turfs, wherein the salt-separating soil base comprises a rough stone layer, a geotextile layer, a crushed stone layer, a polyethylene plastic film layer and a straw layer which are sequentially laid from bottom to top, and the salt-separating soil base is laid on the original saline-alkali soil; the modularization turf include four six stone layers, well stone layer, the fine stone sand bed of filling in proper order from bottom to top, the fine stone sand bed on cover and have the fine cloth of glass, the fine cloth top of glass fill the guest soil layer, the guest soil in situ mix and have the halophilic saline-alkaline microbial manure, the last saline-alkaline grass of planting in advance of guest soil layer.
Furthermore, a plurality of drain pipes are embedded in the straw layer.
Further, the drain pipe leads to a drain.
Furthermore, the particle size of the rough stone layer is 150-200 mm.
Furthermore, the thickness of the soil dressing layer is 40 cm.
Furthermore, the saline-alkali tolerant grass is festuca arundinacea.
Has the advantages that: according to the utility model, the salt isolation effect is realized on the original saline-alkali soil by adopting the salt isolation soil base, the saline-alkali soil can be effectively isolated by the lower geotechnical cloth layer and the upper polyethylene plastic film layer, the migration of salt and the salt return can be greatly reduced when the flood irrigation is carried out in heavy rain, the salt discharge effect is improved, meanwhile, the modular turf is adopted to realize rapid planting, and the problems of low germination rate and difficulty in survival of plants directly sowed in the saline-alkali soil are avoided.
