Chapter 3 Main process construction methods and survival rate assurance measures

1. Planting of seedlings

1. Preparation before planting

1.1 Preparation of seedlings

According to the engineering design drawings, list the varieties, quantities, and specifications of the seedlings, confirm the sources of seedling supply, as well as the transportation conditions and transportation methods to the planting site. Seedlings that meet specifications, are healthy, and are free of diseases and insect pests should be marked one by one.

In addition, the selected large-sized trees should have straight trunks and well-proportioned crowns. Shrubs should have round crowns, tight branches and leaves, and no legs at the base. Flowering shrubs should have lush branches and leaves, tall leaves and strong buds. Prevent old and diseased seedlings from entering the market. High-quality seedlings should meet the following conditions: well-developed and complete root system, short and straight main heel, more lateral roots and fibrous roots close to the rhizome, no splitting of the root system after seedling emergence; thick and straight seedlings, not leggy; evenly distributed main and side branches. , can form a perfect crown; free from pests, diseases and mechanical damage.

1. 2 Excavation and transportation

Excavation:

1. First, verify the varieties and specifications, and try to select them in strict accordance with the requirements stipulated in the bidding documents. The same supply point and breeding batch of seedlings ensure the uniformity of seedling specifications, tree species, sizes, and shapes used in this project. At the same time, there are sufficient changes in quantity to ensure that special circumstances increase the need for conversion.

2. In terms of variety selection, it is necessary to select varieties with superior comprehensive properties based on the environmental conditions and design intentions of the project site. Through a full understanding and analysis of the types, quantities, specifications, and character requirements of the seedlings designed for this project.

3. Carry out root irrigation 1-2 days before excavation of seedlings. The irrigation time and amount of water depend on the weather and soil dryness and moisture conditions to ensure that the plants are transplanted during the entire transplanting process of excavation, transportation and planting. Absorb enough water before planting to strengthen the bonding force between the roots and the soil. This makes digging easier and ensures that the mud ball is not easily broken.

4. Before excavation of seedlings, the following work needs to be done:

Guard poles: tightly wrap the main pole and large main branches of the tree with straw ropes to prevent the tree from being damaged during excavation and transportation. The skin is scratched and the main branch is torn off. After planting, evaporation can be reduced in summer to avoid sunburn.

Crown bundling: Use straw ropes to properly bundle the tree crowns to avoid damage during excavation and transportation. After tying the crown, mark the main viewing surface.

5. Ensure the size of the mud ball when digging seedlings. Generally, the diameter of the mud ball is 8 times the diameter at breast height for trees, and 1/2-1/3 of the crown width for shrubs. The height of a soil ball is generally 70% of its diameter.

6. When digging seedlings, pay special attention to the protection of mud balls and new fibrous roots of cut seedlings. Use sharp tools when digging. Apply Bordeaux liquid to the root system around the surface of the mud ball for disinfection and sterilization. Try to dig in cool and windy weather, and the time should be continuous and compact, never overnight. When the main root is not broken, tie the waist band in time to prevent the mud ball from falling and loosening when cutting the main root. And tightly wrapped with a network of straw ropes. After digging up the seedlings, immediately take corresponding pruning and leaf reduction measures according to the physiological characteristics of different types of seedlings, and apply wax on the incisions.

Transportation of seedlings:

1. Make full arrangements for tools, equipment, manpower, and transportation vehicles before transplanting and excavation.

And do as required according to weather changes. The process is compact and reasonable, and the seedlings can be dug and transported as they are planted. The excavation and planting of all seedlings must be synchronized and coordinated to avoid delays in planting the excavation seedlings and ensure that the seedling transplantation process does not exceed 24 hours.

2. After protecting all trees and shrubs with mud balls and grass ropes, spray water on the grass ropes to moisturize them.

3. During transportation, try to cover the seedlings tightly with oil canopies to avoid wind blowing and avoid pile pressure. This can greatly improve the quality of the incoming seedlings.

4. A crane must be used when digging and transporting large-sized trees. When choosing a crane, pay attention to the tonnage. When tying the hanging rope, place thick sacks or cork between the mud ball and the tree trunk-wrapped straw rope to increase friction, prevent the rope from shifting, and protect the tree body. In addition, two additional guide ropes need to be tied to the crown of the tree to facilitate adjustment of the crown and tip position. The bottom of the mud ball tether is made of thick hemp rope with a "figure-8 knot". The size of the bottom ring should be appropriate. If the ball is too large, it will easily loosen the mud ball. If it is too small, the stability will be poor when lifting. The length of the mud ball and tree trunk tether should be determined according to the size of the ball and the tree crown. When lifting, the angle between the main pole and the horizon should be controlled between 65 degrees and 75 degrees to stabilize the center of gravity. When a large tree is hoisted onto a vehicle, used large tires can be placed at the bottom of the mud ball to avoid uneven stress or damage to the mud ball due to bumps on the road. When shipping large-sized trees and shrubs, they should be tied firmly to prevent them from jumping, and their tree trunks should be cushioned by straw bales and other cushioning materials where they are against the vehicle body.

2. Planting of seedlings

1. Staking out and positioning: According to the design drawings, locate and stake out the construction site in proportion. For large-sized trees, use cuttings to mark the fixed points or use white powder to fix the points. For group planting of small shrubs and ground covers, white pink lines can be used to mark the edge lines of the planting area.

2. Excavation of tree holes: Excavate the day before planned planting and let the sun dry the hole; the size of the tree hole should be slightly larger than the soil ball, and the diameter of the tree hole should be larger than the diameter of the root system or soil ball. 40cm larger, and the depth is 10-20cm larger than the height of the mud ball. In addition, the size of tree holes will be treated differently according to the different living habits of various tree species.

3. Scattered seedlings and loose-rooted seedlings should be dug, transported, scattered, and planted as much as possible to shorten the root exposure time as much as possible to facilitate survival. When scattering seedlings, you should handle and place them gently. When scattering seedlings for street trees, you should place them in the direction of the road. Do not just move the tree trunks, and roll the soil balls as little as possible.

4. Before planting, check whether the size and depth of the pit are consistent with the pit diameter required by the root system and soil ball specifications. If they are not consistent, they should be repaired.

5. Before planting, the root system of exposed seedlings should be pruned. Cut off broken roots, split roots, roots infected with diseases and insect pests, and overly long roots. The cuts should be smooth. Seedlings and shrubs with soil balls should be cut off. Cut the grass rope surrounding the crown of the tree. Pruning of tall trees should be done before and after the seedlings are dispersed, that is, before planting. In order to ensure consistent height, neatness and beauty for trees and shrubs with a height of less than 3m without an obvious main tip, they can be pruned after planting, and the cuts should be flush with the trunk. Do not leave dead pegs to avoid affecting healing; when cutting short, pay attention to leaving the outer buds. The distance between the cut and the bud should be appropriate, usually about 10mm from the bud, and the cut should be slightly inclined into a horseshoe shape; when pruning large branches above 20mm, the cut should be coated with preservatives. Can promote healing and protect against pests and rain.

6. Seedling cultivation: Use the excavated light soil directly as planting soil and push it next to the tree hole. If there is no light soil, the garbage will be transported out and guest soil that meets the planting requirements will be transported in for later use.

a) For the cultivation of trees with soil balls, backfill the tree holes with light soil to the height of the bottom of the soil balls, and mix the holes with carbendazim powder to effectively kill harmful substances on the ground. bacteria to prevent erosion of the plant roots, then place the soil ball on the top soil surface, select the main viewing surface in an orientation, open the soil ball packaging, and take out the packaging (if the soil of the soil ball is soft, the bottom of the soil ball is packed (the soil does not need to be taken out), first pour the rooting agent mixed with water on the roots, then build soil from the edge of the pit to around the soil ball, and tamp it down in layers (be careful not to wash away the mud ball), the height of the soil should be 2/3 of the depth of the soil ball. At that time, a ring-shaped cofferdam was built beside the tree hole, with a height of 10-20cm.

b) For the planting of other flowering shrubs and ground cover plants, this type of plants is mainly planted in groups to ensure neat planting, especially the outer plants, which must be in good shape. Before planting ground cover plants, further organize the soil in the planting area to make the planting even and tidy. After completing the above steps, pour enough water to set the roots for the first time. When watering, pour in evenly from all sides. Return to water the next day and use the excavated new soil to level the weir. Then enter the post-planting maintenance stage. Newly planted seedlings generally need to be watered every day in the first week, every other day in the 2-3 weeks, and every 3-5 days in the 4-6 weeks. If the weather is cold and windy, take measures to prevent wind and heat preservation.

c) The larger trees in this project prefer deep, fertile, humus-rich, moist but well-drained soil. They avoid water accumulation. When planting, they should not be buried deeply and should only be planted shallowly. It can be raised appropriately, and the top of the acupoint on the surface of the soil ball is about 10cm. At the same time, when planting, fill the hole with carbendazim and water the roots with rooting agent to ensure the survival rate of the seedlings.

7. When planting, trees should not be tilted, and trees should be kept vertical. When there are tree bends, the tree tips and roots should be on the same vertical line. The bends of street trees should be in the direction of the road and parallel to the road.

8. Planting and backfilling should be carried out by experienced workers in accordance with normal practices. Plants should be planted vertically, 20-30mm deeper than the planting depth in the nursery. Trees and shrubs should be inspected and approved by the supervising engineer before planting.

9. For bare-root plants, first put the topsoil at the bottom of the pit, with a loose thickness of about 150mm, then spread an appropriate amount of organic fertilizer (depending on the nature of the topsoil), and cover the fertilizer with a 50-100mm backfill layer. , so that the roots do not come into contact with fertilizers. Then place the bare-root plant in the center of the tree pit and spread out the roots in a natural form. All broken or damaged roots should be cut off to encourage good root growth.

Backfill the soil around and above the tree pit and compact it appropriately. When the backfill reaches half the depth of the root system, lift the plant slightly, then backfill the soil to a thickness of 150mm per layer and compact it. The plant is surrounded by soil to form a shallow basin-shaped concave (shallow soil basin) reservoir that is the same size as the tree pit and is about 150mm deep.

10. The planting paths and rows of trees must be horizontal and vertical. When planting, one tree can be accurately planted every 10 or 20 trees at the specified position as a basis for the alignment of the front and rear trees, and then planted separately.

11. When planting trees and shrubs, basically retain the crown and tree shape of the original trees. Before planting, provide the supervision engineer with relevant information such as the source of the plant for inspection; pay attention to protecting the root system and crown of the plant during transportation; if the plant cannot be planted in time on the same day, take certain measures (such as fake planting, etc.) to protect it.

12. Support and binding: After the seedlings are planted, support and binding should be adopted immediately for tall trees. The support binding is mainly lead wire or steel wire binding and lifting piles. The supports are tied firmly to prevent wind and settlement from causing the root ball to move and affect the root system. Use rubber tubes to cover the steel wires tied to the tree trunks to avoid damaging the bark.

13. After planting, trees or shrubs should be watered according to maintenance requirements, and should be watered thoroughly. Within half a month, water them thoroughly 2-3 times. Thereafter, watering is generally done once a week, depending on climate conditions, until the plant survives.

14. In planting areas where there are artificial or other obstacles to plant growth, warning and protective measures such as signs, support ropes, and temporary fences should be set up to ensure the survival and normal growth of plants.

15. The planting area should be kept clean and tidy, and no debris should be piled up or used as a temporary site

2. Lawn planting

1. The site should be leveled

p>

Because the smoothness of the site is directly related to the future growth quality of the lawn, this process is particularly important.

1.1 Preliminary leveling: first pick up the surface garbage and then plow the land to a depth of not less than 30cm, and then break up the soil clods. For land with a lot of debris, you can use a 10mm*10mm screen to screen it once to ensure that the debris is removed, and then use an iron rake to level the land. Sections with poor soil quality need to be partially or completely replaced with soil. The depth of soil replacement should be no less than 30cm. After soil replacement, water is poured to make it sink and compact, and then backfilled with soil. Repeat this several times until the site is level.

1.2 Weed removal and pest control before lawn construction: In order to prevent the growth of weeds after planting lawns, in addition to clearing tree roots and grass roots during land preparation, glyphosate, paraquat and other killing chemicals can be used For systemic conductive herbicides, spray 75-100g per acre, usually one month before building a lawn. To prevent insect infestation, pesticides such as methamidophos and phoxim can be sprayed one week before planting to achieve the effect of killing insects.

1.3 Fertilize before planting grass: Spread mature organic fertilizer 3kg/m2 and compound fertilizer 0.08kg/m2 evenly on the leveled site, then plow the soil, then rake it flat and rake it. Fine, ready to sow.

2. Lawn planting construction

After the soil is leveled and raked fine, lawn planting can be carried out.

2.1 Sowing method: The seed amount is generally 8-10g/m2, and the sowing method uses a combination of broadcast and mechanical sowing. After sowing, the soil should be covered in time with a soil thickness of 0.5-1cm, and then pressed with an iron roller to ensure uniform emergence of seedlings. For watering work and maintaining moisture, you can cover the lawn bed with a straw curtain to reduce watering. After all the grass seedlings have emerged, remove the straw curtain. Note that the curtain must be removed on a cloudy day or before evening to prevent direct sunlight from burning the grass seedlings.

2.2 Lawn planting method: On the flat ground, open a trench 5cm deep with a row spacing of 20-30cm, put the torn grass blocks into the trench, then fill it with soil and compact it. .

In order to improve the survival rate and shorten the seedling slowing period, two points should be paid attention to during the transplanting process: first, the turf should be covered with an appropriate amount of mulch soil; second, the time from digging to planting should be shortened as much as possible. It is best to dig and plant the grass on the same day. After planting, it is necessary to fully irrigate and remove weeds. After one month of maintenance, it can become a flat surface.

3. Maintenance management and ensuring survival rate

In order to ensure the one-time blooming of seedlings after planting and the one-time survival rate of seedlings, maintenance measures during the planting process are also one of the keys.

1. Maintenance of trees and shrubs

(1) Support and binding:

a. After the seedlings are planted, large-sized seedlings should be supported and bound immediately. According to Choose appropriate support piles based on tree species and specifications. Large-sized seedlings adopt the method of windproofing the main trunk of the crown with three-leg iron wire cable-staying, combined with the support method of tying the main trunk with cross pole wooden piles to prevent uneven settlement.

b. Since the construction period of this project is in autumn and winter, insulation measures must be taken to ensure the survival rate of seedlings (such as camphor, magnolia, etc. must be wrapped with mulch, straw rope, and the bottom is compacted and covered with film) .

(2) Irrigation: After planting, plants should be irrigated in a timely and appropriate amount depending on weather conditions and soil dryness and moisture conditions to maintain the effective moisture of the soil. For tree species with higher requirements for water and air humidity, water and spray the leaves in the early morning or evening. Water accumulated on trees after rain should be removed promptly.

(3) Loose soil and weeding: Large weeds under trees and shrubs should be eradicated, and the soil around the roots of trees should be kept loose. Soil that is prone to compaction must be loosened once a month during the peak transpiration season. The depth of the soil is appropriate so as not to damage the root system.

(4) Prevention and control of pests and diseases: Carry out timely prevention and control of pests and diseases according to the growth characteristics of each tree species in the design. Spray broad-spectrum antibiotics to prevent pests and diseases before they occur, and spray them immediately after they occur.

(5) Pruning: Mainly prune inner branches, leggy branches, diseased branches, cross branches, drooping branches, sprained branches and dead branches of trees; pruning of shrubs should promote the luxuriance and distribution of branches and leaves. Evenly. Pruning of flowering shrubs should be conducive to the formation of short branches and flower buds. Pruning should follow the principle of "first up and then down, first inside and then outside, remove the weak and keep the strong, remove the old and keep the new".

(6) Fertilization: According to the characteristics of the plant and the terrain where it is located, base fertilizer can be applied once during planting and top dressing twice a year during the defect liability period to promote plant growth or extend the green period. Fertilization can be carried out by foliar spraying or pit application according to different methods depending on the specific situation. Fertilization should be carried out on sunny days.

2. Lawn maintenance

2.1. Watering must wet the root layer. The depth of the soil layer that should be soaked is 10cm to prevent long-term water accumulation on the ground. Irrigation keeps the soil moist and promotes lawn growth. During the normal growth period, irrigation for "greening", "freezing" and "drought resistance" can be carried out as needed.

2.2. Pruning and weeding: Prune appropriately and appropriately according to the growth potential, carry out manual weeding or chemical weeding, and deal with lawn trimming.

2.3. Fertilizer: Apply fertilizer once in spring and autumn, preferably organic fertilizer and compound fertilizer alternately.

2.4. The prevention and control of pests and diseases should be based on prevention. Regular preventive spraying should be carried out during high temperature and high humidity seasons where pests and diseases are prone to occur, and spraying should be carried out promptly after the occurrence of pests and diseases.

3. Rescue work

3.1. When a storm approaches, some branches of the crowns of trees that have fallen down and are affecting traffic should be pruned in time to ensure that walking is as convenient as possible.

3.2. After the storm, carry out rescue operations according to priorities. First, rescue the fallen trees that obstruct traffic and affect the appearance; for trees that are difficult to survive when planted on the spot, the crowns of the trees should be cut off and sent to nurseries for planting and maintenance, and the fallen trees should be straightened in time.

4. Replanting of dead trees

Replanting trees should still use the original tree species with similar specifications. If the original tree species or specifications are changed, they must be coordinated with the original landscape. The replanting season is the same as the greening planting season.

5. Measures to ensure survival rate

In order to ensure the survival rate of seedlings, our company's project department will establish a complete and strict management system to strictly control the quality of seedlings from various aspects. Close, planting close, maintenance close.

Chapter 4 Prevention and Maintenance Management Plan for Quality Weak Links

1. Main technical points of maintenance work

As the saying goes, "three points, "Seven points of management". After the greening construction is completed, in order to achieve satisfactory construction results, maintenance work must be carried out continuously over a long period of time. The company will organize a special maintenance team for this project to maintain it in strict accordance with the "Jiangsu Province Landscaping Plant Maintenance Technical Regulations (Trial)".

2. Weeding and soil loosening

Remove weeds in the green space, keep the green space tidy, reduce the competition between weeds and trees for water, fertilizer and nutrients, which is conducive to the growth of trees; at the same time, remove Some pests and diseases lurk, reducing the chance of pests and diseases occurring. Loose the soil surface to increase the soil's air permeability and achieve the effects of water retention, air permeability, and warming. This is done twice in spring and autumn, once or twice a month in summer, and once in winter with a shallow plow to a depth of about 5-20CM. It will be fully leveled after the freezing season in the coming year. Make sure the seedlings are growing well.

3. Drainage and irrigation

Strictly maintain smooth drainage in green spaces, and promptly drain local accumulated water after heavy rains. Every big tree must avoid root flooding after rain and avoid water accumulation in green spaces. , Side ditches retain water; after heavy rains in summer and autumn and winter freezes, the slopes of drainage ditches must be repaired in time to ensure smooth drainage and stable slopes.

Irrigate in a timely manner according to the soil moisture content. In summer, the watering time should be after four o'clock every afternoon; Excessive humidity affects plant root growth. When the soil moisture reaches the "farmable" state the next morning, immediately loosen the soil to cut off the upper capillaries and reduce the evaporation of surface water. Fertilization is one of the irreplaceable maintenance points to ensure the vigorous growth of green trees. For newly planted precious tree species, top dressing should be applied outside the roots, mainly ammonium dihydrogen phosphate (nitrogen and phosphorus compound fertilizer) and potassium dihydrogen phosphate (phosphorus and potassium compound fertilizer); for trees and shrubs, pig manure, chicken manure, etc. should be used before winter. Apply base fertilizer with decomposed organic fertilizer; apply extra-root fertilizer to large trees and precious trees. Use 0.2-0.5 KH2PO4 urea or NH4H2PO4 to spray the leaf surface and tender tips with a sprayer. The spraying time is after 4 pm on a sunny day.

4. Plastic pruning

Prune the seedlings appropriately according to their growth trend. The main purpose is to promote the recovery of seedlings and improve their ornamental value. Pruning is generally carried out when the seedlings enter the dormant period in the fall, while plastic surgery is mainly carried out in the spring before the seedlings germinate. Mow the lawn regularly, once or twice a month in spring and once every two months in autumn and winter. Stencil patterns are often smooth and smooth with sharp edges.

5. Prevention and control of pests and diseases

The two roads are characterized by a large number of trees of the same species and close spacing between rows. Once a disease or pest occurs, it is easy to spread quickly. Therefore, we must pay more attention to pest control. It is necessary to check the quarantine of purchased seedlings and never allow seedlings with quarantine pests and diseases to enter the construction site. During the maintenance period, the plant protection policies of "prevention first, comprehensive management" and "elimination of early growth, removal of small ones, and removal of small ones" will be implemented.

6. Replanting of seedlings

For confirmed dead seedlings, promptly remove them and formulate a replanting plan according to the season, and carry out replanting of the same specifications and quality according to the requirements of Party A and the supervisor. of seedlings replanted.

7 Assault Maintenance Measures

After winning the bid, our company will set up a maintenance working group headed by comrades with many years of maintenance experience to implement responsibilities, assign people in sections, and clarify maintenance standards. , Implement reward and punishment measures. The company's maintenance department is directly responsible for pruning, pest control, and watering within the bid section; daily weeding, garbage collection, and debris removal are the responsibility of the contractor. The company organizes regular or irregular assessments and scores twice a month, which are linked to the contractor's economics according to the maintenance standards of the bidding documents. If the assessment score is less than 90 points for three consecutive times, the maintenance qualification will be disqualified and the maintenance salary will be deducted. At the same time, in the event of major political events or special holidays, after receiving notice from the owner or supervisor, our company guarantees to rush to the bidding site within 30 minutes, and dispatch vehicles to mobilize urban greening maintenance workers at any time to arrive at the site immediately to carry out the work. assault. The assigned assault mission will be completed within twelve hours, and there will never be any failure to complete the assault mission on time due to lack of time or temporary lack of personnel.
