Abstract
A saline-alkali soil improvement method is characterized in that through utilization of agricultural waste and construction of a salt filtering layer on soil surface, accumulated salt in the surface soil is treated in a carding manner, communication between underground water and the soil surface is allowed, and salt is discharged through a salt discharge channel; meanwhile, residual soil surface salt on to-be-treated saline-alkali soil mainly remains on non-woven geotextile, and all that is needed is to replace the non-woven geotextile once when the soil surface salt is accumulated to a certain amount. The main raw material is the agricultural waste, the cost is lower, and environmental treatment is facilitated.
Description
Technical field
The present invention relates to the technical field of Saline-alkali Field Control, specifically a kind of saline-alkali soil improvement method based on agricultural greenhouse.
Background technology
Saline Land problem and mankind's activity, particularly agricultural irrigation is closely related.Research shows, saline Land not only causes the massive losses of the destruction of resource, agricultural production, but also biosphere and ecological environment are constituted certain threat, is mainly manifested in environment and the harm of economic two aspects.
The reason of saline Land be soil and underground saliferous too high, under strong surface evaporation effect, underground shallow layer water is transported to earth's surface through capillary tube and is evaporated, capillary tube is in the process of earth's surface water delivery, also the salinity in water being taken to earth's surface, after water is evaporated, soil salt is risen by capillarity and accumulates in upper soll layer, salinity is left in earth's surface and ground thin solum, and the long-pending moon of mouth is tired causes saline Land.At present, administer salt-soda soil and following measures are usually taken: bury hidden pipe underground, by the long-term salt discharge of rainfall or freshwater resources;Plantation saline alkali tolerant plant Cacumen Tamaricis;Soil cement adds geomembrane and subtracts and ooze.But these Saline-alkali Field Control measures exist desalination alkali poor effect, not thoroughly, the shortcoming such as investment greatly and not easily popularization.
Summary of the invention
It is an object of the invention to carry out integrating and improving for existing salt-soda soil treatment technology, it is provided that a kind of saline-alkali soil improvement method based on agricultural greenhouse, realize the improvement of salt-soda soil Land Environment with low cost.
The technical solution used in the present invention is:
A kind of saline-alkali soil improvement method based on agricultural greenhouse, comprises the steps:
Step one, choose the straw of crops, dead leaf, the agricultural residue such as the feces of people and animals, carry out sterilization treatment after adding aqueous solution, after filtration, obtain sterile raw material slag and sterile raw material liquid；
Step 2, pending salt-soda soil being divided, the length and width in every piece of pending salt-soda soil, all less than 50m, leaves salt discharge passage wide for 1m between each pending salt-soda soil；
Step 3, sterile raw material slag is sprinkling upon on pending salt-soda soil, after uniformly digging, lays ground floor non-woven geotextile at upper soll layer；
Step 4, plugging vertical grout pipe in pending salt-soda soil, arrange plasm pouring in plane pipe and make plasm pouring in plane pipe be positioned at above non-woven geotextile on the upper soll layer in Saline-alkali Field Control region, vertical grout pipe connects with plasm pouring in plane pipe；
Step 5, above grout pipe lay second layer non-woven geotextile, in grout pipe, pass into sterile raw material liquid, pending salt-soda soil is carried out improvement drip irrigation.
Step 6, complete improvement drip irrigation after, above pending salt-soda soil set up booth.
Step 7, in grout pipe, pass into clear water, pending salt-soda soil is carried out desalinization of soil by flooding or leaching drip irrigation.
Preferably, it is also possible to select following technical scheme:
It is 1:300-350 that aqueous solution described in step one includes the weight ratio of nitric acid, nitric acid and water.
It is 1:100-120 that aqueous solution described in step one includes the weight ratio of ferrous sulfate, ferrous sulfate and water.
The weight of the agricultural residue described in step one and water is 1:500-600.
Step one often obtains the sterile raw material slag of 1 weight portion, it is possible to extract the sterile raw material liquid of 450-550 weight portion simultaneously.
The node that completes improveing drip irrigation described in step 5 is the drip irrigation sterile raw material liquid of 450-550 weight portion on the pending salt-soda soil of spreading 1 weight portion sterile raw material slag.
Should being provided with drainage catheter on booth inwall described in step 6, drainage catheter is connected with plasm pouring in plane pipe.
The present invention has the advantage that and has the benefit effect that
1, the adopted raw material major ingredient of the present invention is agricultural residue, less costly, and contributes to the process of environment；
2, " accumulation of salt in the surface soil " is not carried out hard blocking by the present invention, but adopt the mode of combing, allow the communication between subsoil water and earth's surface, by salt discharge channel row from salinity, simultaneously, remain in the earth's surface salinity on pending salt-soda soil and predominantly stay on ground floor non-woven geotextile, when earth's surface salinity gathers a certain amount of, change a non-woven geotextile.
3, above pending salt-soda soil, having set up the booth with water source collecting function, prevent water to be derived from pending salt-soda soil further, having shifted to salt discharge passage thus controlling salinity.
Detailed description of the invention
Below in conjunction with embodiment, technical scheme is specifically described.
A kind of saline-alkali soil improvement method based on agricultural greenhouse, comprises the steps:
Step one, choose the straw of crops, dead leaf, agricultural residue and the aqueous solutions etc. such as the feces of people and animals are as raw material, each raw material components is by weight ratio: 1 weight portion agricultural residue, 1.8 weight portion nitric acid, 5 parts by weight of ferrous sulfate, 550 weight parts waters, sterilization treatment, obtaining sterile raw material slag and sterile raw material liquid after filtration, the processing procedure in step one can carry out always, and the sterile raw material slag every time taken out and the mass ratio of sterile raw material liquid are 1:500.
Step 2, pending salt-soda soil being divided, the length and width in every piece of pending salt-soda soil, all less than 50m, leaves salt discharge passage wide for 1m between each pending salt-soda soil；
Step 3, sterile raw material slag is sprinkling upon on pending salt-soda soil, after uniformly digging, lays non-woven geotextile at upper soll layer；
Step 4, plugging vertical grout pipe in pending salt-soda soil, arrange plasm pouring in plane pipe and make plasm pouring in plane pipe be positioned at above non-woven geotextile on the upper soll layer in Saline-alkali Field Control region, vertical grout pipe connects with plasm pouring in plane pipe；
