Detailed Description
The technical solution of the present invention is further described below with reference to specific embodiments:
a treatment method for landscaping soil remediation comprises the steps of using the method for alkaline soil (the pH value of the soil is 8.2-9.0) remediation, sampling and detecting raw soil, determining the proportion of soil additives, pretreating the soil, adding the soil additives into the pretreated soil, and uniformly mixing; the sampling detection of the raw soil comprises the detection of the pH value of the soil, the content of organic matters in the soil and the EC value of the soil. After the pH value of the finished soil, the organic matter content of the soil and the EC value of the soil are measured, the proportion of the additive to be added is determined according to the measurement result, and the organic matrix and the mineral material are added in the process of adding the organic matrix and the mineral material, wherein the adding proportion of the organic matrix and the mineral material is not more than 20 percent of the weight of each group of raw soil.
When the proportion of the soil additives is determined, selecting raw soil and dividing the selected raw soil into a plurality of groups with the same amount, adding the soil additives with the same amount into each group of raw soil and uniformly mixing, wherein the organic matrix and the mineral material of each group of soil additives are different in proportion; after the soil additive is added, the pH value, the organic matter content and the EC value of each group of raw soil added with the soil additive can be detected, and the optimal proportion of the organic matrix and the mineral material is determined.
Wherein the soil additive comprises organic matrix and mineral material, the mineral material comprises river sand, Maifanitum or active carbon; the organic matrix is powder particles prepared by fermenting and carbonizing mushroom sticks, bagasse and animal wastes. The bacillus subtilis and the plant lactic acid bacteria in the mushroom stick effectively reduce the pH value of the soil through the metabolites of the bacillus and the lactic acid bacteria and indigenous microorganisms in the soil and the amplification effect (the effect of the bacillus subtilis and the plant lactic acid bacteria), and simultaneously, the metabolism can also generate nutrient substances such as vitamins, amino acids, polysaccharides and the like, so that the nutrient substances can be absorbed by plants. The animal waste can effectively reduce the salt content in the animal waste through thorough fermentation, and the increase of salt content is avoided, so that the EC value of the soil is improved.
Wherein, the soil pretreatment comprises the pulverization of the soil and the sieving treatment of the soil. Before soil is crushed, original soil is dried by adopting an excavator to dig, evaporation of water in the soil is increased, and the water content in the original soil is not more than 20% so as to crush and screen the soil.
After soil crushing treatment, soil after will smashing leaves the ground and sieves, screens out the impurity in the soil, sieves and can operate a plurality of times repeatedly, because the unable abundant oxygen in the contact air of underground soil, leaves the ground and sieves and can make soil and air fully contact, is favorable to increasing the oxygen content in the soil.
The soil sieving can be processed by adopting a soil sieving crushing bucket, the structure of the soil sieving crushing bucket is shown in figure 1 and comprises a bucket 1, a shovel arm 2, a first swing arm 3 and a second swing arm 4, one side of the bucket 1 is provided with an installation seat 7, the installation seat is provided with a first pin hole 5 and a second pin hole 6, and one end of the shovel arm 2 is installed at the second pin hole 6 through a pin shaft; one end of the first spiral arm 3 is arranged at the first pin hole 5 through a pin shaft, the other end of the first spiral arm 3 is connected with one end of the second spiral arm 4 through a pin shaft, the other end of the second spiral arm 4 is connected to the shovel arm 2 through a pin shaft, and the mounting seat 7, the shovel arm 2, the first spiral arm 3 and the second spiral arm 4 are connected to form a quadrilateral structure; a hydraulic rod 8 is further connected to the pin between the first radial arm 3 and the second radial arm 4, one end of the hydraulic rod 8 is movably connected to the pin between the first radial arm 3 and the second radial arm 4, and the other end of the hydraulic rod 8 is movably connected to the shovel arm 2.
1 one side of scraper bowl is equipped with shovel soil mouth 9, and 1 other one side of scraper bowl is equipped with soil filtering mouth 10, is equipped with two at least sieve rollers 11 at 1 inside positions that are close to soil filtering mouth 10 of scraper bowl, and sieve rollers 11's surface is equipped with a plurality of annular tool bits 12, and adjacent sieve roller 11 is last annular tool bit 12 dislocation distribution. A power device, such as an electric motor (not shown), is also provided on the bucket 1 for driving the screening rollers in rotation.
When soil sieves, the shovel arm is installed on the car, move near the soil that waits to sieve with the car, move the scraper bowl to the assigned position through the shovel arm, will wait that the soil that sieves goes into the scraper bowl through the shovel mouth in, make with the help of the angle of hydraulic stem adjustment scraper bowl strain the soil mouth down, the shovel mouth upwards, start power device makes soil spill from sieving between the annular tool bit of roller, realize the mesh of sieving, fall from above ground through highly realizing soil with the help of the shovel arm, realize the contact of soil and air. After the sieving is finished, the angle of the bucket is reversely adjusted by the hydraulic rod to pour out the filtered impurities in the bucket.
Before the soil additive is added, the soil can be sterilized, and the soil is preliminarily sterilized by fully contacting ultraviolet rays in the air.
To further illustrate the protocol of the present invention, this example provides the following data, as shown in the following table:
in the above table, the soil amount of each group of raw soil, screened soil and unscreened soil is the same, wherein the screened soil and unscreened soil are respectively tested by adding the same amount of soil additives in the same proportion, and the data show that:
the organic matter content of the two groups of pretreated powder sieve soils is improved compared with the original soil and meets the planting soil industry standard (CJT 340-2016); the four groups of unpretreated silt screened soil cannot be fully and uniformly mixed with soil due to no pretreatment, so that the difference of measurement results is large;
the pH value of the original soil is slightly alkaline, the pH values of the two groups of pretreated powder screening soils are reduced to be slightly neutral, and the soil meets the planting soil industry standard (CJT 340-2016); the four groups of unpretreated silt screened soil can not be fully and uniformly mixed with soil due to no pretreatment, so that the pH value of the soil is not effectively reduced;
the EC value of the original soil is 0.35(ms/cm), the EC values of the two groups of pretreated screened soil are improved but still meet the planting soil industry standard (CJT 340-2016); and because the four groups of unpretreated powdered soil are not pretreated, the soil additive cannot be fully and uniformly mixed with the soil, and the detection result of the EC value of the soil is unstable.
In conclusion, for the same improvement material and the same formula design, the improvement effect of the pretreated screened soil is better and more stable, while the improvement effect of the non-pretreated screened soil is poorer and unstable, namely, the soil can be effectively improved and the effect is stable through pretreatment.
The present invention is further explained and not limited by the embodiments, and those skilled in the art can make various modifications as necessary after reading the present specification, but all the embodiments are protected by the patent law within the scope of the claims.
