The application finds that the existing cultivation soil treatment mode can only be adapted to common scenes, and for special terrains such as basin and hill terrains, the existing cultivation soil treatment method does not meet the requirements, namely the growth condition of plants at the planting position is not good. Therefore, through long-term research, the applicant provides a planting soil treatment method for greening engineering, which can adapt to the land and hilly terrain of the basin and the hill, and the specific implementation mode is as follows:
the thickness of the surface layer of the planting soil in the scheme is set according to the type of the plants to be planted, if the surface layer of the planting soil is set to be uniform, the problem of shallow soil layers of partial soil layers can occur, the shallow soil layers are the condition which is easy to generate in the basin and hilly terrain, and the scheme carries out regional setting and treatment according to the type of the specific planting plants, so that the problem of shallow soil layers can be solved; and the grain diameter of the surface soil block of the planting soil is also set according to the species of the planting species, so that the planting soil can be more suitable for specific environments, particularly special environments, and is convenient to adjust according to actual conditions. And on the land formed by the delayed hydrochlorides, the serious water and soil accumulation is easy to occur, so that the planting substrate is treated before the backfilling of the planting soil, the problem that the planting substrate has a watertight area or the serious water and soil accumulation is deepened is solved, a drain pipe, a water filtering layer or a water filtering pipe and the like can be arranged on the planting substrate, the redundant water can be discharged, and the problem of the serious water and soil accumulation is solved. Therefore, the scheme can adapt to the special environment created by the basin and hill terrain, and further avoid the problems of shallow soil layer and serious water and soil ponding.
The step S1 is to determine the standard of the grain size of the soil blocks on the surface of the planting soil as follows:
when the planted plants are large and medium trees, the grain size of soil blocks on the surface layer of the planted soil is less than or equal to 5 cm;
when the planted plants are small trees, large shrubs, large vines, the grain diameter of soil blocks on the surface layer of the planted soil is less than or equal to 4 cm;
when the planted plants are bamboo, shrub, perennial flower and rattan, the grain size of the soil blocks on the surface layer of the planted soil is less than or equal to 3 cm;
when the planted plants are lawns, grass flowers and ground covers, the grain size of the soil blocks on the surface layer of the planted soil is less than or equal to 2 cm;
the step S1 is to determine the thickness of the surface layer of the planting soil by:
when the planted plant is a tree and the diameter of the tree is more than or equal to 20cm, the thickness of the surface layer of the planted soil is more than or equal to 180 cm;
when the planted plant is a tree and the diameter of the tree is less than 20cm, the thickness of the surface layer of the planted soil is more than or equal to 100 cm;
when the planted plants are shrubs and the height of the shrubs is more than or equal to 50cm, the thickness of the surface layer of the planted soil is more than or equal to 60 cm;
when the planted plants are shrubs and the height of the shrubs is less than 50cm, the thickness of the surface layer of the planted soil is more than or equal to 45 cm;
when the planted plant is flower, lawn or ground cover, the thickness of the surface layer of the planted soil is more than or equal to 30 cm.
Step S2 specifically includes:
treating the planting soil, wherein the control of the parameters of the planting soil comprises the following steps: PH, total salt content, density, organic matter content, non-pore porosity, alkaline-hydrolyzable nitrogen content, available phosphorus content, available potassium content, cation exchange capacity, soil texture, and gravel mass fraction.
Step S3 specifically includes:
mixing raw soil and peat soil according to a weight ratio of 1: 1; after the peat soil is subjected to physical and chemical treatment, the content of organic matters is 50% -70%; the PH value is 5.5-6.5; the total nutrient is 1.5-2.5%.
The volume weight of the general peat soil is very small, the general dry weight is between 0.2 and 0.3 g/cubic centimeter, and the wet weight is between plus 0.6 and 0.7 g/cubic centimeter, while the volume weight of the general soil is between 1.25 and 1.75 g/cubic centimeter, and the wet weight is between about 1.9 and 2.1 g/cubic centimeter. From this, it can be estimated that the dry weight of the peat soil is 18-20% of the weight of the general soil, and the wet weight is 33% of the weight of the general soil. Of course, it is impossible to use peat in all areas of the slope. The relative cost of the fully used peat soil is higher on the one hand, and the biggest defect of the fully used peat soil is that the wind resistance and root fixing force are not strong enough on the other hand. The applicant therefore made improvements: one part of peat is mixed with one part of ordinary soil to prepare mixed soil to improve the soil. Therefore, not only can the weight of the soil be reduced by 25-30%, but also the air permeability and nutrients of the soil are improved, and unexpected technical effects are achieved.
In order to adapt to the basin and hilly terrain, light soil which is light in weight, rich in organic matters and trace elements, capable of preserving moisture and fertility, loose and free of hardening and strong in cultivation adaptability needs to be adopted, so that the planting requirement is met, and the light soil is economical. There are two disadvantages if the light soil is used to replace the general soil (original soil) entirely:
(1) the wind-proof fixing ability is insufficient, and the planting and management of trees and shrubs are limited;
(2) the cost is high.
Two above factors are combined, according to the thickness of backfill soil, adopt in this scheme: ordinary soil and peat soil are mixed for use, the volume weight of the soil is reduced and the soil quality is improved in a limited way (one part of ordinary soil and one part of northeast peat soil are mixed according to the ratio of 1:1 as a basis).
Step S4 specifically includes:
eliminating impervious layers within the range of the planting soil substrate; and when backfilling the cultivation soil, adopting layered and segmented backfilling, and paving and tamping the backfilled soil layer by layer.
The surface layer of the planting soil at the position where the surface layer of the planting soil is connected with the road is 3-5 cm lower than the kerbstone; the surface layer of the planting soil is straight with the edge opening line; the slope of the surface layer of the planting soil is 0.3-0.5%.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. according to the method, the particle size of the planting surface soil block and the thickness of the planting surface are selected according to the type of the planted plant, so that the problems that the soil layer is shallow due to the influence of the plant root on the soil in the growth process of the planted plant, even the plant root cannot be covered by the soil layer, the plant root is exposed outside and easily necroses, or the plant and the soil are low in firmness and easily blown down by wind can be solved.
2. The invention improves the soil by mixing one part of peat into one part of common soil to prepare mixed soil; therefore, not only can the weight of the soil be reduced by 25-30%, but also the air permeability and nutrients of the soil are improved, and unexpected technical effects are achieved.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not used as limitations of the present invention.
Example 1:
a planting soil treatment method for greening engineering comprises the following steps:
s1: determining the grain diameter and the surface thickness of soil blocks on the surface layer of the planting soil according to the types of the planted plants;
s2: respectively carrying out physicochemical treatment on the planting soil backfilled in different planting areas according to the species of the planted plants;
s3: sterilizing the planting soil; improving the planting soil;
s4: treating the planting substrate, and backfilling the planting soil; determining the relative position of the planting surface layer and the road and the gradient of the planting soil surface layer.
Specifically, the method comprises the following steps:
the grain size of the planting soil required by different planted plants is shown in Table 1:
TABLE 1 particle size of soil blocks on the surface of planting soil
The thickness of the surface layer of the planting soil required for different plants is shown in Table 2:
the surface layer of the planting soil needs to meet the basic requirements:
1) the surface layer of the planting soil can not have obvious low water injection and water accumulation, and the surface soil layer with the depth of 30cm in the flower bed and the flower environment planting field must be loosened;
2) the surface layer of the planting soil is clean and tidy, the particle size of the contained gravels is larger than 3cm and is not more than 10 percent, the particle size of the gravels is smaller than 2.5cm and is not more than 20 percent, and the impurities such as weeds and the like are not more than 10 percent; the particle size of the soil blocks is in accordance with the specification of table 1;
3) the surface layer of the planting soil is connected with the road (retaining wall or kerbstone) at the soil, and the planting soil is 3 cm-5 cm lower than the kerbstone; the planting soil is basically straight with the edge line;
4) the surface of the planting soil should be flat and have a slight gradient after preparation, and when no design requirement exists, the gradient is preferably 0.3% -0.5%.
The physical and chemical indexes of the planting soil meet the requirements of table 3:
TABLE 3 physical and chemical indexes of planting soil
The planting soil can be disinfected by adopting a spraying or irrigating method, a toxic soil method and a fumigation method, but because the scheme is mainly implemented in a garden or a green lawn, the fumigation method is adopted in the embodiment: the fumigant is injected into soil by using a soil injector or a soil sterilizer, and the surface of the soil is covered with a covering material such as a film, and the covering material is diffused in a closed or semi-closed facility to kill germs. After the soil is fumigated, the seeds can be sown after the pesticide is fully diffused, otherwise, the pesticide damage is easily caused.
In order to ensure the survival and later growth of the plants, the soil which can not meet the requirement of planting soil quality in green land is improved. According to the characteristics of the seedlings to be planted and the requirements on soil, mixing raw soil and peat soil according to a proper proportion, uniformly stirring the mixture, fully paving the mixture in a green land with the thickness of not less than 30cm, wherein arbor and shrub are determined according to the sizes of pits and soil balls for improving soil and manually changing soil, and organic fertilizers can be properly added according to the needs. The preparation of the improved medium is as follows: the weight ratio of the peat soil is 1: 1; if the plants are acid-loving plants such as Theaceae, the ratio of peat soil to raw soil should be increased, and the ratio of the sum of the weights can be increased to 1.2: 1; in the case of woody plant with fleshy root such as Magnoliaceae, coarse sand can be added to improve water permeability.
Physical and chemical indexes of peat soil: 50-70% of organic matters; 25-40% of humic acid; the pH value is 5.5-6.5; the total nutrient is about 2 percent; belongs to a natural organic fertilizer. The characteristics are as follows: water retention, ventilation, help plants to absorb nutrients, increase survival rate and reduce maintenance cost.
In the embodiment, the northeast peat soil is adopted, the volume weight of the northeast peat soil is very small, the dry weight is generally 0.2-0.3 g/cubic centimeter, the wet weight is just 0.6-0.7 g/cubic centimeter, the volume weight of common soil is 1.25-1.75 g/cubic centimeter, and the wet weight is about 1.9-2.1 g/cubic centimeter. From this, it can be estimated that the dry weight of the peat soil is 18-20% of the weight of the general soil, and the wet weight is 33% of the weight of the general soil. Of course, it is impossible to use peat in all areas of the slope. The relative cost of the fully used peat soil is higher on the one hand, and the biggest defect of the fully used peat soil is that the wind resistance and root fixing force are not strong enough on the other hand. Therefore, in practical use, a part of peat is mixed with a part of ordinary soil to prepare a mixed soil to improve the soil. This not only reduces the soil basis weight by 25-30%, but also improves the permeability and nutrients of the soil.
The light soil which is light in weight, rich in organic matters and trace elements, water-retaining and fertilizer-retaining, loose and not hardened and strong in cultivation adaptability is required to be adopted, so that the planting requirement is met, and the light soil is economical. There are two disadvantages if the light soil is used to replace the ordinary soil:
1) the wind-proof fixing ability is insufficient, and the planting and management of trees and shrubs are limited.
2) The cost is high.
The two factors are combined, and according to the thickness of the backfill soil, the following is suggested to be adopted in the construction: ordinary soil and peat soil are mixed for use, the volume weight of the soil is reduced and the soil quality is improved in a limited way (one part of ordinary soil and one part of northeast peat soil are mixed according to the ratio of 1:1 as a basis).
A water filtering layer is arranged before backfilling to ensure the water permeability of the planting substrate, and the following steps can be selected: 1) backfilling an aggregate water filtering layer, wherein graded cobble (crushed) stones, ceramsite, expanded perlite and the like can be backfilled, and the backfilling depth is not less than 300 mm; 2) laying a filter layer, namely geotextile, a PE (polyethylene) water filtering plate and the like, and generally placing the filter layer above the water filtering aggregate to play a role in filtering; 3) the breathable water filtering pipe is arranged by adopting a 110 or 160PVC pipe with the length of 1m, small holes with the diameter of 10mm are formed in the pipe wall, the small holes are arranged at intervals of every 100mm and 100mm, the bottom end of the breathable water filtering pipe is sealed by a sealing head or water-permeable geotextile, the side wall of the breathable water filtering pipe is wound by two weeks of geotextile, and the breathable water filtering pipe is embedded into three to four tree holes to play a role in ventilation or water filtration.
The backfilling process flow of the cultivation soil comprises the following steps:
cleaning sundries → inspecting soil quality → transporting the vehicle to a backfilling point → mixing light soil by adopting a manual-matching machine → layering and ramming tightly → backfilling to a designed elevation → trimming and modeling.
Specifically, the method comprises the following steps:
1) before backfilling earthwork, cleaning sundries such as earthwork garbage and the like;
2) inspecting the earthwork quality, inspecting the water content of the earthwork, and mixing one part of common soil and one part of northeast peat soil according to the proportion of 1: 1;
3) backfilling in a layered and segmented manner, wherein the backfilled soil is paved and tamped in a layered manner;
4) the back filling soil sinks due to the fact that the weak soil is paved too thick and tamped insufficiently, and ground cracks and even sinks are caused;
because the backfill area is wide and large in area, the nutrient soil is mixed on site by matching an excavator and a loader. Transporting the planting soil to the site according to the required quantity, then uniformly spreading, loosening and leveling the soil by using an excavator, uniformly spreading peat soil on the planting soil according to the proportion of 1:1, and repeatedly stirring for 4-5 times by using the excavator and a loader in a matching manner, so that the nutrient soil is uniformly mixed, and the particle size of soil blocks is not more than 10 mm. And (5) manually digging and smashing the local uneven part, and removing large soil blocks by using a rake. Considering the factors of landform settlement after raining and watering, all landforms exceed the pre-settlement amount of the designed elevation by 5cm, so that the settled elevation meets the design requirement.
During construction, attention should be paid to: when the planting soil is backfilled and shaped, a pre-settling amount needs to be reserved, and the situation that the site is lower than the designed elevation and has to be filled with nutrient soil is prevented.
