Road greening maintenance plan

Road greening maintenance plan (1)

(1) Winter maintenance and management

In winter, in Beijing, especially on both sides of the road, the general terrain is open. Air convection, coupled with the wind speed driven by high-speed vehicles, causes trees to sway violently, which can easily damage the root system of trees, accelerate the loss of water in trees, and reduce the ability of trees to protect themselves from cold, frost, and cold. The following antifreeze and heat preservation measures can be adopted in winter:

First, measures to wrap tree trunks: For example, in the Beijing Economic and Technological Development Zone, the trunks of deciduous trees on street trees in the Beijing Economic and Technological Development Zone are wrapped with fabrics for winter cold protection. Wrap the tree trunk tightly and then wrap it with straw rope to moisturize and prevent cold. Then use mulch to keep the roots of the tree warm and cold-proof, so that the survival rate of the plant in the next year will reach 99%.

Second, measures to build wind barriers: For example, it is difficult for tree species such as cedar to survive the winter in Beijing. Especially the spring wind reduces the adaptability of cedars. Wind barriers can be used to reduce the wind speed and ensure the safe wintering of trees.

Fourth, build an insulation shed: For seedlings such as big-leaf boxwood, small-leaf boxwood, and paved cypress that are planted that year, when the area is large, it is not ideal to use general cold-proof measures. , by using wooden strips and non-woven fabrics to build an insulation shed, you can make the seedlings survive the winter safely. Sparsely planted large-leaf boxwood, red maple and other seedlings can be wrapped with non-woven fabrics to protect them from the cold.

Fifth, build up soil on the root neck and cover it with mulch film: For Henan juniper, magnolia and other seedlings in the green belt, cover the entire tree pit with mulch film after filling with frozen water, and then build 20-30cm of soil around the root neck. of mounds. Use fine soil to build up the surrounding area. This will not only prevent frost damage to the plant roots, but also reduce water evaporation.

Sixth, cover the soil and seal the ridges: For newly planted roses that year, cover 30-40cm of soil mounds after filling with frozen water. Generally, no pruning is done. Premature pruning will lead to the phenomenon of "burning strips" , generally wait until the next spring before pruning.

Seventh, whitening the trunks to prevent frostbite: This is an important task for street trees to prevent cold and disease in winter, especially for newly planted deciduous trees. The whitening time is generally from late October to mid-November. The ratio of whitening is: water: quicklime: sulfur powder: salt = 40:10:1:0,5. The height is generally 1 or 2m. The height of the same road section is consistent, which can achieve a neat and beautiful effect.

(2) Spring maintenance and management

First, in the management of seedlings in spring, cold-proof materials should not be removed suddenly and prematurely. A gradual transition method should be adopted to prevent the seedlings from not adapting. The removal of the thermal insulation shed depends on the weather. Generally, the removal time of the windproof barrier in Beijing is in early April and after the Qingming Festival. In order to prevent the trees from being damaged by the wind, holes were drilled on the southeast side of the insulation shed in advance to let out wind, and all of them were removed after the trees adapted.

Second, watering and fertilizing: Spring management is mainly to increase the ground temperature, water enough spring water in a timely manner and apply more organic fertilizers. By watering and fertilizing the trees, the trees can increase their ability to resist diseases and facilitate rooting. In practice, stick fertilizer can be used to fertilize street trees. Holes are drilled with nails around the tree pond and the stick fertilizer is buried, which can play the role of top dressing.

(3) Summer maintenance and management

First, for summer maintenance and management, pay attention to water and fertilizer management. At the same time, the shape and pruning of the color blocks in the central isolation belt and green belt of the road are generally combined with a Maintenance inspections are carried out twice a year and pruning is carried out on May Day and National Day.

Second, summer maintenance mainly focuses on the prevention and control of pests and diseases. Since street trees are affected by microclimate diversity and dense population, pests and diseases occur at different times and are difficult to prevent. At the same time, the impact on humans and the environment must also be considered during the prevention and control process, as well as the protection of plant natural enemies. In recent years, the use of biological control has been promoted, such as the use of new sexual attractants to control petiole moths, Bacillus thuringiensis to prevent hornworms, and killing larvae to prevent inchworms, etc., which have achieved good results.

(4) Autumn maintenance and management

Autumn maintenance and management work mainly involves the rational pouring of frozen water and fertilization.

Reasonable frozen water can not only ensure that the above-ground parts of plants absorb sufficient water, but also protect the underground roots from dry and windy winters, which is conducive to the safe overwintering and germination of plants in the coming year. Watering in winter should be based on weather changes and should not be watered too early, causing the new shoots to grow excessively. Reduce the frequency of watering in October to increase drought resistance. It is best to pour the frozen water for the last time until it freezes.

At the same time, reasonable fertilization in autumn will help promote the growth of plants and the lignification of trees. It is also conducive to the safe overwintering and growth of plants in the next year. This requires choosing the time, type and fertilization of fertilization. quantity.

2. Road greening and lawn maintenance plan

For cool-season lawns, it is necessary to water the greening water in spring, strengthen fertilization, comb out the dead grass, and comb out the rotten grass with a silk rippling Clean and drill holes before applying compound fertilizer. Then water to stimulate new root growth and increase fertility in the lawn. Only by enhancing the ability to resist diseases can you survive the summer safely.

In summer, the lawn should be mowed once every 10-15 days as required. After pruning, the lawn should be sprayed in time, or the roots should be irrigated with 25% carbendazim wettable powder to control the occurrence of diseases. The hot and humid weather in July is unfavorable for the growth of lawns. It is also the dormant period of lawns and the most difficult period for maintenance. The hay layer should be removed in time, because there are often a large number of pathogens in the hay layer, which is the source of new diseases. At the same time, the original The straw layer weakens the permeability and clears the place early. In addition, during periods of high temperature, muggy weather, and continuous rainy weather, spray pesticides such as thiophanate methyl, carbendazim, and cantilozin every week or as soon as it clears up. Use alternately to prevent brown spot, Pythium wilt, and Fusarium wilt. .

In autumn, when there is less rain and the weather becomes cooler, the diseases are generally less severe, and lawn rust is more serious. For example, 1,000-1,500 times of thiophanate can be used for prevention and control, which will have a good effect, but it must be used alternately with Subaoli and thiophanate methyl.

3. Maintenance plan for road greening ribbons

Hedgerows are tree species with strong germination and branching ability and are resistant to pruning. They are densely planted in strips and have the function of separation and beauty. shape. For example, big-leaf boxwood, golden-leaf ligustrum, red-leaf barberry, juniper cypress, and small-leaf boxwood are commonly used tree species for hedge modeling.

With the increase in color-leaf plants in the past two years, color blocks composed of color-leaf tree species, such as purple-leaf dwarf cherry, winter jasmine, forsythia, and Ditang, are commonly used in large-scale environmental greening. of tree species. But there are different pruning methods. The central dividing strip of the road should be trimmed to a height of 1-1 or 2 meters that can block people's sight. It should be trimmed horizontally and vertically, neatly and beautifully. To make hedges grow lush, different pruning methods are used because the plants grow at different heights.

Road Greening Maintenance Plan (2)
