The city wetland has high comprehensive value, and the ecological, economic and social benefits of the wetland park play a crucial role in improving the city environment and the life of residents.

[0003] In the process of city wetland construction, the natural landscape topography is often simulated by artificial micro topography to enhance the overall ornamental property. In the process of landscape construction, the traditional method is to first fill the micro topography, and then plant green plants. However, due to the large area and high slope of the micro topography, the green plants are planted by using mechanical equipment after the micro topography is filled, which will inevitably damage the micro topography that has been filled, and then a second repair is needed after the green plants are planted, which causes the extension of the construction time.

[0004] Therefore, it is necessary to provide an improved technical solution for the above-mentioned deficiencies of the prior art. SUMMARY

[0016] The high and steep slope green planting method as described above, preferably, the micro-terrain slope of the lowest layer is planted by the mobile crane and the automobile crane, the multiple automobile cranes are distributed circumferentially along the micro-terrain slope toe, and the hoisting range of the multiple self-cranes and the multiple automobile cranes covers the green planting range of the micro-terrain slope of the lowest layer.

[0017] The high and steep slope green planting method as described above, preferably, the multiple hoisting points are located on the construction road, and the construction road spirally climbs to the top of the micro-terrain slope along the micro-terrain slope.

[0039] The following will be described in detail with reference to the accompanying drawings Figures 1-4 A high and steep slope green planting method will be further described in detail.

[0040] A high and steep slope green planting method, comprising:

[0041] Step S1, micro-terrain layer filling;

[0042] Step S2, planting hole excavation and reserved construction access 1: when the micro-terrain filling reaches the preset layer height, the planting hole excavation of the micro-terrain slope 3 of the layer is performed, wherein the planting hole in the construction access 1 range is not excavated;

[0043] Step S3, green plant transfer: along the construction access 1, the green plant is transferred to the layer top by using the truck-mounted crane;

[0044] Step S4, scattering and planting seedlings: the truck crane is used at the hoisting point 2 located at the top of the layer to scatter and plant seedlings on the micro-terrain slope 3 of the layer;

[0045] Step S5: repeating steps S1 to S4 to plant green plants on the next layer of micro-terrain slopes 3 until the planting holes of each layer of micro-terrain slopes 3 are planted with corresponding green plants;

[0046] Step S6: planting green plants in the construction access 1;

[0047] When planting green plants on the next layer of micro-terrain slopes 3, the construction access 1 of the previous layer is retained, and the construction accesses 1 of each layer are connected to each other.

[0048] In the specific implementation of the present application, the green plant planting method for high and steep slopes further comprises:

[0049] Step S0, green plant selection and transportation: in advance, the seedling source is investigated on site, and a horizontal comparison is made between different seedling sources. The seedlings intended to be used are pre-ordered. The selection of seedlings should meet the design requirements as much as possible. The selected seedlings should not have a long transplanting period. When the size of the seedlings for counter-season planting is large, the soil and water can be stored in the appropriate season. The entire plant is sprayed with 1-3% transpiration inhibitor to reduce water and nutrient evaporation, inhibit plant physiological activity, and promote the plant to be in a semi-dormant state. When the seedlings need to be transported over a long distance, the soil ball of the seedlings is wrapped with wet grass. Large trees are placed on the truck with the crown inclined towards the tail of the truck, and soft material is used to pad the contact between the tree and the truck to prevent scratching the bark. The weather change should be considered when the plants are transported. Generally, the seedlings should be transported on a wet and cloudy day, and preferably in the evening. Through appropriate drug treatment, the seedlings are transported to the planting site overnight. The seedlings should be transported by vehicles with a canopy that can block the sun and wind. Large seedlings should be arranged with the front roots and the rear stems. Small seedlings should be arranged vertically, wrapped in single packages, and separated by layers. If the transportation time exceeds 4 hours, cooling packs should be prepared and measures such as water spraying and humidification should be taken during the journey.

[0050] In step S1, before the micro-terrain is filled, the height of the micro-terrain is determined according to the hoisting range of the truck crane. Specifically, the height of the corresponding layer is determined according to the hoisting radius and height range of the truck crane, combined with the slope rate of each layer of slope surface,

[0051] The lowest point of the micro-terrain is 80.0m, the highest point is 90.2m, the total height difference is greater than 10m, and the calculated gentle slope rate is greater than 26%. The micro-terrain is filled in three layers, the filling height of the lowermost layer is 4m, and the filling height of the upper two layers is 3m.

[0052] In other embodiments of the present application, when the hoisting range of the truck-mounted crane is sufficient to cover the planting area of each type of green plants on the micro-terrain slope 3, the micro-terrain layering filling height is determined according to the elevation range of each type of green plants planted on the micro-terrain slope 3.

[0053] By layering the micro-terrain in the above manner and planting the green plants on the micro-terrain slope 3 from bottom to top, the traditional concept of planting green plants from top to bottom after the overall filling of the micro-terrain is broken. Through layering, a reasonable working space is reserved for the mechanical equipment at the top of each layer, facilitating mechanical operation. At the same time, since the micro-terrain layering height is determined according to the hoisting range of the mechanical equipment, i.e., the green plant planting of the corresponding layer of the micro-terrain slope 3 can be performed at the hoisting point 2 at the top of each layer without the need for secondary transportation, thereby avoiding damage to the micro-terrain slope 3 that has been filled. In addition, the construction access 1 is reserved for green plant transportation, and a fixed transportation route is used to avoid a large amount of damage to the micro-terrain slope 3 that has been filled caused by mechanical equipment transportation.

[0054] Step S3 specifically comprises: along the construction access 1, using the truck-mounted crane to transfer the green plants from the micro-terrain slope foot to the top of the layer;

[0055] Step S4 specifically comprises:

[0056] Step S41, scattering seedlings: the tree seedlings are scattered on the planting hole edge according to the regulations (design drawing or fixed point wooden stake), which is called "scattering seedlings". The seedlings should be handled with care to avoid damaging the roots, bark, branches and soil balls. The scattering speed should be adapted to the planting speed. The seedlings are scattered and planted at the same time, and the scattering is completed before planting. The exposure time of the tree roots is minimized. The remaining root system of the seedlings in the false planting trench should be buried with soil in time. The seedlings used as street trees and hedges should be pre-measured in height, further graded, and then scattered to ensure that the specifications of adjacent seedlings are basically consistent. The height difference of adjacent seedlings of the same type of street trees should not exceed 50 cm, and the diameter difference should not exceed 1 cm. For evergreen trees, the best shape should face the main viewing surface. For seedlings with special requirements, they should be seated according to the regulations, and the position should not be mistaken.

[0057] The design drawing needs to be carefully checked before and after scattering seedlings, and errors should be corrected immediately to ensure the correctness of the tree planting position.

[0058] Step S42, planting seedlings: after scattering seedlings, the seedlings are placed in the hole, straightened, layered, and the seedlings are lifted to the appropriate degree, and the process of tamping and fixing is called "planting seedlings".

[0059] (1), operation method

[0060] The planting method of bare-root tree: put the sapling into the hole and straighten it, fill the soil to half of the hole, then gently lift the sapling to make the root part level with the ground, make the roots naturally stretch downward, then step on the soil or use a wooden stick to tamp the soil, continue to fill the soil until it is slightly higher than the edge of the hole, then tamp the soil again, finally make a water weir around the hole with soil.

[0061] The planting method of sapling with soil ball: when planting sapling with soil ball, first check if the depth of the hole is consistent with the height of the soil ball, if not, dig deeper or fill the soil in time, do not blindly move the soil ball. After the soil ball is put into the hole, pad a small amount of soil around the bottom of the soil ball to fix it, make sure the trunk is straight. Cut the packaging material and try to remove it (the perishable packaging material can be left). Then fill the soil to half of the hole, use a wooden stick to tamp the soil around the soil ball, continue to fill the soil and tamp it, make sure not to break the soil ball when tamping. Finally, make a water weir around the hole with soil.

[0062] (2) Matters needing attention

[0063] The tree should be vertical, if the trunk is curved, the curve should be towards the local prevailing wind direction. The row and column planting must be horizontal and vertical, the difference between left and right should not exceed half of the trunk.

[0064] Planting depth: bare-root trees, the original root neck soil mark should be level with the original soil; shrubs should be level with the original soil; saplings with soil balls, the top of the soil ball should be higher than the original soil due to soil settlement.

[0065] For row and column planting, "marker trees" should be planted first, the method is: every 20 plants or so, measure the position with a tape measure, plant one first, then use these marker trees as a reference to plant the rest.

[0066] After the water weir is built, untie the grass rope around the crown and remove it to make the branches stretch out.

[0067] The stability of sapling planting support is an important guarantee for improving the survival rate of saplings. Large and valuable trees can be as high as 8-9 meters, even 10 meters or more. For example, a planted ginkgo tree is 8-9 meters high, with a diameter of 25 cm and a crown width of 3.5-4 meters. The tree is large and has poor stability, especially under wind load, which makes it more prone to instability. Therefore, the ordinary triangular support frame cannot meet the stability requirements of large trees during planting. The anti-toppling support frame has been improved, using a steel pipe support frame with high stiffness and strength. To increase the stability of the support, a steel belt is used to connect all the supports at the bottom of the support to form a whole.

[0068] However, for sapling planting at the position of micro-topographic slope 3, the planting method is different from that on flat ground, and it is not convenient to set up supports. Therefore, the supports need to be cut according to the terrain to make the support system evenly stressed.

[0069] After the green plants are planted, the seedlings are pruned and shaped according to the whole, and water is poured according to the planting, and the seedlings are supported once after pouring. According to the diameter of the seedlings, the soil ball specification of the seedlings is determined, the planting hole should be enlarged and deepened (usually about 30cm larger than the soil ball), and a water seepage layer is formed to ensure repeated watering and moisture in the high temperature period, and no water accumulation. And hit the shade net, the shade net should be 1.2-1.5m higher than the top of the plant.

[0070] The plurality of hoisting points 2 are distributed along the circumferences of the layer tops of the respective layers, and the plurality of truck cranes are located on the plurality of hoisting points 2 to plant green plants on the corresponding layer micro-terrain slope 3, and the hoisting ranges of the plurality of truck cranes cover the green plant planting ranges of the corresponding layer micro-terrain slope 3.

[0071] In specific embodiments of the present application, to improve the green plant planting speed, the same number of truck cranes as the number of hoisting points 2 on each layer top are configured to jointly plant green plants on the layer micro-terrain slope 3, and the hoisting radius and hoisting height range of the plurality of truck cranes completely cover the projection range of the corresponding layer micro-terrain slope 3 in the horizontal and vertical directions, so that after the plurality of truck cranes are transported to the corresponding layer micro-terrain slope 3, the entire green plant planting on the corresponding layer micro-terrain slope 3 can be completed, avoiding repeated transportation of the truck cranes and delaying the planting process.

[0072] The lowermost layer of the micro-terrain slope 3 uses truck cranes and automobile cranes to jointly plant green plants, and the plurality of automobile cranes are distributed along the circumferences of the micro-terrain slope feet, and the hoisting ranges of the plurality of self-cranes and the plurality of automobile cranes cover the green plant planting range of the lowermost layer of the micro-terrain slope 3.

[0073] In specific embodiments of the present application, the soil compaction degree of the micro-terrain slope 3 during filling is not sufficient to support the walking and use of large machinery such as automobile cranes, so when selecting mechanical equipment, truck cranes with smaller self-weight are used for green plant planting, but to further improve the planting speed, a plurality of automobile cranes are configured at the micro-terrain slope feet to plant green plants on the lowermost layer of the micro-terrain slope 3 within their hoisting range. For the lowermost layer of the micro-terrain slope 3, the slope foot automobile crane is combined with the layer top truck crane to further improve the planting speed, while increasing the height of the lowermost layer, thereby reducing the number of micro-terrain layers and shortening the planting time.

[0074] The plurality of hoisting points 2 are located on the construction access road 1, and the construction access road 1 spirally climbs along the micro-terrain slope 3 to the top of the micro-terrain slope.

[0075] In combination with the drawings Figure 2As shown, in the specific embodiment of the present application, in order to reduce the climbing angle of the truck crane and improve the stability of the mechanical equipment, the construction road 1 spirally climbs along the micro-terrain slope 3 until the top of the micro-terrain slope; in order to realize cross operation and further improve the planting speed, the truck crane hoisting point 2 is arranged on the construction road 1, that is, the construction road 1 passes through the multiple hoisting points 2 located at the top of each layer, and spirally climbs along the micro-terrain slope 3 to the top of the micro-terrain slope. Since the green plants in the next layer of the micro-terrain slope 3 need to be planted, the construction road 1 in the last layer needs to be reserved, and thus the hoisting point 2 in the last layer is also reserved to enable cross operation of the seedling scattering, seedling planting, micro-terrain filling, and planting hole excavation in the last layer. However, since the hoisting point 2 in the last layer occupies the construction road 1, the green plants in the next layer need to wait until the planting of the green plants in the last layer is completed before being transported to the position.

[0076] The construction road 1 linearly climbs along the micro-terrain slope 3 to the top of the micro-terrain slope.

[0077] In combination with the accompanying drawings Figure 3 As shown, in the specific embodiment of the present application, the hoisting point 2 is distributed circumferentially along the top of each layer, and the construction road 1 linearly climbs along the micro-terrain slope 3, that is, the operation on the construction road 1 and the operation on the hoisting point 2 do not interfere with each other. When the green plants in the next layer of the micro-terrain slope 3 are planted, the construction road 1 and the hoisting point 2 in the last layer are reserved, and the construction roads 1 in each layer are connected to each other, and thus the independent construction of the micro-terrain slope 3 in each layer is realized. Specifically, since the construction road 1 and the hoisting point 2 do not interfere with each other, the transportation of the green plants corresponding to the micro-terrain slope 3 in each layer is not affected by the seedling scattering and seedling planting operations in the last layer, so that the micro-terrain slope 3 corresponding to each layer can be simultaneously and independently operated after filling is completed, thereby greatly improving the planting speed of the green plants.

[0078] After the green plants in the micro-terrain slope 3 corresponding to each layer are planted except at the construction road 1 and the hoisting point 2, the green plants at the hoisting point 2 are first planted by the construction road 1, and then the green plants within the range of the construction road 1 are planted.

[0079] In combination with the accompanying drawings Figure 4 As shown, in other embodiments of the present application, when the green plants in the next layer of the micro-terrain slope 3 are planted, the hoisting point 2 in the last layer is not reserved, that is, after the planting hole excavation corresponding to the green plants in the last layer of the micro-terrain slope 3 is completed, that is, after the green plants outside the construction road 1 are planted, the green plants in the next layer of the micro-terrain slope 3 are planted.

[0080] When the green plants in the uppermost layer of the micro-terrain slope 3 are planted, the green plants within the range of the construction road 1 are also transported to the top of the layer;

[0081] Specifically, the truck-mounted crane moves along the construction road 1 towards the slope toe while performing the micro-terrain filling, planting hole digging, seedling scattering, and seedling loading of the upper construction road 1.

[0082] In other embodiments of the present application, when the number of green plants in the construction road 1 is small, the green plants can be transported to the top of the layer when the uppermost layer of the micro-terrain slope 3 is planted. Therefore, when the green plants in the construction road 1 are planted, the step of transporting the green plants can be omitted, and a backward planting method is used. Specifically, the truck-mounted crane moves along the construction road 1 towards the slope toe while performing the micro-terrain filling, planting hole digging, seedling scattering, and seedling loading of the upper construction road 1. The seedlings are scattered and planted simultaneously, and the scattering and planting are completed in succession to minimize the exposure time of the roots.

[0083] Specifically, the truck-mounted crane moves along the construction road 1 towards the slope toe while performing the micro-terrain filling, planting hole digging, seedling scattering, and seedling loading of the upper construction road 1. The seedlings are scattered and planted simultaneously, and the scattering and planting are completed in succession to minimize the exposure time of the roots.

[0084] In other embodiments of the present application, when the number of green plants in the construction road 1 is small, the green plants can be transported to the top of the layer when the uppermost layer of the micro-terrain slope 3 is planted. Therefore, when the green plants in the construction road 1 are planted, the step of transporting the green plants can be omitted, and a backward planting method is used. Specifically, the truck-mounted crane moves along the construction road 1 towards the slope toe while performing the micro-terrain filling, planting hole digging, seedling scattering, and seedling loading of the upper construction road 1. The seedlings are scattered and planted simultaneously, and the scattering and planting are completed in succession to minimize the exposure time of the roots.

[0085] The planting hole digging method is determined according to the slope of the micro-terrain slope 3.

[0086] When the slope is ≤18°, mechanical excavation is used; when the slope is >18°, manual excavation is used.

[0087] Before the seedlings are transported, the ground should be prepared and the planting holes should be dug. It is best to plant the seedlings as soon as they arrive. If the seedlings cannot be planted in time, they should be planted temporarily and shaded. The good soil with base fertilizer should be backfilled at the bottom of the hole. The plants should be soaked in 1-3% disinfectant and 5-8% rooting agent before planting to promote root healing and rooting.

[0088] When digging holes on a slope, a small platform should be created on the slope first, and then the holes are dug on the platform. The depth of the hole is calculated from the lower edge of the slope. The position should be accurate and the size should be appropriate. The surface soil and bottom soil should be separated and piled on the side of the hole. Because the organic matter content of the surface soil is high, when filling the soil for planting trees, the lower part of the planting hole should be filled first, and the bottom soil should be filled on the upper part and used as a water weir.

[0089] When digging holes in newly filled soil, the bottom of the hole should be compacted. If the soil quality is poor, the size of the hole should be increased, and the debris should be screened out and removed. If there are substances such as lime slag, furnace slag, permeable concrete, and concrete that are harmful to tree growth, the hole diameter should be increased by 1-2 times, the harmful substances should be removed completely, and good soil should be used to dig the hole.

[0090] The quality of the planting hole has a decisive impact on the growth of the seedlings after planting. In addition to determining the location according to the design, the hole diameter should be determined based on the size of the root system or soil ball and the soil quality (generally, it should be 20-30 cm larger than the specified root system or soil ball diameter). The depth of the hole should also be determined based on the root system type of the tree species. The hole or trench diameter should be consistent from top to bottom to prevent the roots from expanding or the soil filling from being solid during planting.

[0091] In other embodiments of the present invention, manual excavation mainly uses tools such as hoes, shovels or pickaxes. Specifically, with a fixed mark as the center of the circle, a circle is first drawn on the ground with a specified hole diameter (diameter), and then vertically excavated downward to a specified depth along the four sides of the circle. The bottom of the pit is then loosened and leveled. When planting seedlings with exposed roots, it is best to pile up a small mound in the center after loosening the bottom of the hole (planing) to facilitate the stretching of the roots; mechanical excavation uses a digging device for planting vegetation in a reservoir with patent number ZL202121987135.3. When using this mechanical device to excavate planting holes, if hard objects such as large rocks, cables and water pipes are encountered, the operation can be automatically stopped to avoid damage, and the cables and water pipes can be avoided from being damaged. In addition, this device is easy to carry and easy to use. Compared with traditional manual digging of planting holes, it saves costs and improves efficiency. During operation, the axis must be aligned with the fixed position and dug to the specified depth. Level the bottom of the pit and manually assist in finishing if necessary.

[0092] Before carrying out micro-topography layered filling, soil improvement should be carried out first.

[0093] In a specific embodiment of the present invention, in order to shorten the time for early terrain shaping and planting soil improvement as much as possible, the original fish pond soil nearby is used to improve the soil quality and make rational use of it, thereby reducing the purchase of foreign planting soil and shortening transportation time. The quality of the soil is closely related to whether the plant can survive. Good soil conditions can play a favorable role in promoting the growth of the plant. When planting plants, it is necessary to ensure that the planting soil has sufficient thickness. In addition, it is also necessary to ensure that the soil is fertile and relatively loose. It must also have good drainage and air permeability to ensure that the role of soil cultivation and plant maintenance is fully exerted.

[0094] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.

A method for planting green plants on steep slopes, characterized in that: include: Step S1, micro-topography layered filling; Step S2, excavating planting holes and reserving construction access roads: When the micro-topography is filled to a preset layer height, excavating planting holes on the micro-topography slope of that layer, wherein the planting holes within the construction access road range are not excavated; Step S3, green plant transfer: along the construction access road, use the truck crane to transfer the green plants to the top of the layer; Step S4, scattering and planting seedlings: the vehicle crane scatters and plants seedlings on the micro-topography slope at the lifting point located at the top of the layer; Step S5: Repeat steps S1 to S4 to plant green plants on the next layer of micro-topography slope until the green plants corresponding to the planting holes of each layer of micro-topography slope are excavated and planted. Step S6: Planting green plants within the construction access road; When planting green plants on the micro-topography slope of the next layer, the construction access roads of the previous layer should be retained, and the construction access roads of each layer should be connected to each other; There are multiple lifting points, and the multiple lifting points are distributed along the circumference of each layer top. Multiple truck cranes are located at the multiple lifting points to plant green plants on the micro-topography slopes of the corresponding layers. The lifting ranges of the multiple truck cranes cover the green plant planting ranges of the micro-topography slopes of the corresponding layers. The plurality of hoisting points are located on a construction access road, and the construction access road spirally climbs along the micro-topography slope to the top of the micro-topography slope; When planting green plants on the top layer of micro-topography slope, the green plants within the construction access road range will be transported to the top of this layer; The step S6 specifically includes: while the truck crane moves along the construction access road toward the slope foot, the truck crane performs micro-topography filling, planting hole excavation, seedling spreading, and seedling loading of the upper construction access road; The lowest micro-topography slope is planted with green plants using a truck-mounted crane and a mobile crane. Multiple mobile cranes are distributed circumferentially along the foot of the micro-topography slope. The lifting range of multiple self-mounted cranes and multiple mobile cranes covers the green plant planting range of the lowest micro-topography slope.

2. A method for planting green plants on a steep slope as claimed in claim 1, characterized in that: The method of excavating the planting holes is determined according to the gradient of the micro-topography slope.

3. A method for planting green plants on a steep slope as claimed in claim 2, characterized in that: When the slope is ≤18°, mechanical excavation is used; when the slope is >18°, manual excavation is used.

4. A method for planting green plants on a steep slope according to any one of claims 1 to 3, characterized in that: Before carrying out micro-topography layered filling, soil improvement should be carried out first.
