Road Greening Maintenance Plan (I)

(A) winter maintenance management

In winter in Beijing, especially on both sides of roads, the general open terrain and air convection, coupled with the wind speed of high-speed vehicles, cause trees to swing violently, which easily leads to damage to the roots of trees, accelerate the water loss of trees, and reduce the ability of trees to keep out cold, freeze and keep out cold. The following anti-freezing and heat preservation measures can be taken in winter:

1. Measures to wrap the trunk: For example, street trees in Beijing Economic and Technological Development Zone should be treated with winter cold protection for deciduous trees of paulownia. The trunk should be wrapped tightly with expected cloth, then wrapped with straw rope to keep moisture and prevent cold, and then the roots should be insulated with plastic film to prevent cold, so that the survival rate of paulownia in the second year can reach 99%.

Second, measures to build windbreak barriers: Cedar and other tree species are difficult to overwinter in Beijing, especially in spring. The windbreak wall can be used to reduce the wind speed and ensure the safe wintering of trees.

Fourth, build insulation shed: For the seedlings planted in that year, such as Buxus macrophylla, Buxus microphylla, cypress, etc., when the area is large, it is not ideal to take general cold protection measures. According to the size of the area, wooden strips and non-woven fabrics can be used to build a heat preservation shed, so that the seedlings can survive the winter safely. For sparsely planted seedlings such as Buxus macrophylla and Acer truncatum, non-woven fabrics can be used for cold protection.

Fifthly, cultivating the root neck and covering it with plastic film: after pouring frozen water, covering the whole tree pit with plastic film, and then cultivating the root neck with 20-30cm mound. Compacting the surroundings with fine soil. This can not only prevent frostbite of plant roots, but also reduce water evaporation.

6. Cover the soil and seal the ridge: For the newly planted rose in that year, the mound covered with 30-40 cm after being filled with frozen water is generally not pruned, and the phenomenon of "burning strips" will appear if it is pruned too early, and it is generally not pruned until the next spring.

Seventh, the trunk is painted white to prevent freezing: this is an important work for street trees to prevent cold and disease in winter, especially for newly planted deciduous trees. The painting time is generally between 10 and10. The plastering ratio is: water: quicklime: sulfur powder: salt = 40:10:1:0,5. The heights are generally 1 and 2m. The height of the same road section is consistent, which can achieve a neat and beautiful effect.

(2) Spring maintenance management

First, in the management of spring seedlings, the cold-proof materials should not be removed suddenly and prematurely, and the method of gradual transition should be adopted to prevent the seedlings from being unsuitable. According to the weather conditions, the time for removing wind barriers in Beijing is generally in early April, after Qingming. In order to avoid wind damage to trees, holes should be drilled in the southeast side of the insulation shed in advance, and all trees should be removed after they are adapted.

Second, watering and fertilizing: spring management focuses on raising ground temperature, watering spring water in time and applying more organic fertilizer. By watering and fertilizing trees, trees can increase their disease resistance and help them take root. In practice, street trees can be fertilized with stick fertilizer, that is, punching holes around the tree pool with nails and burying the stick fertilizer can play the role of topdressing.

(3) summer maintenance management

First, summer maintenance management, pay attention to water and fertilizer management, trim the shape of color blocks in the road center isolation belt and green belt, generally combined with twice-yearly maintenance inspection and May 1 ST and 11 th.

Second, the maintenance in summer is mainly based on pest control. Because street trees are influenced by microclimate diversity and population density, the occurrence time of pests and diseases is uneven and it is difficult to prevent them. At the same time, the impact on people and environment and the protection of natural enemies of plants must be considered in the prevention and control process. In recent years, biological control has been widely used, such as using new sex attractants to control petiole moths, Bacillus thuringiensis to control moths, and killing young urine to control inchworm, and achieved good results.

(4) autumn maintenance management

The maintenance and management in autumn is mainly to reasonably pour frozen water and fertilize.

Reasonable frozen water can not only ensure that the aboveground parts of plants absorb enough water, but also protect the underground roots from dry and windy winter, which is conducive to the safe overwintering and germination of plants in the coming year. According to the weather change, watering winter water should not be too early, which will lead to the rapid growth of new buds. /kloc-reduce watering times in October and increase drought resistance. It is best to pour out the frozen water for the last time until it freezes.

At the same time, reasonable fertilization in autumn is conducive to promoting the growth of plants and lignification of trees, and is also conducive to the safe overwintering and growth of plants in the coming year, which requires choosing the time, type and dosage of fertilization.

Second, the road greening lawn maintenance scheme

For the cool-season lawn, it is necessary to water the green water in spring, strengthen fertilization, comb the hay, comb the rotten grass with a silk rake, and apply compound fertilizer after punching. Then water the lawn to stimulate new roots to sprout and increase fertility. Only by strengthening disease resistance can we spend the summer safely.

In summer, mow the lawn once every 10- 15 days as required, spray the medicine in time after mowing, or irrigate the roots with 25% carbendazim wettable powder, which can control the occurrence of diseases. The hot and humid weather in July is not conducive to the growth of lawn, and it is also the dormant period of lawn. In the most difficult period of maintenance, the hay layer should be cleaned in time, because there are often a lot of germs in the hay layer, which is the source of new diseases, and at the same time, the permeability of the original hay layer is weakened, so it should be cleaned early. In addition, pesticides such as thiophanate-methyl, carbendazim and chlorothalonil should be sprayed every week or when the weather is hot, sultry and rainy. Alternating use can prevent brown spot, Fusarium wilt and Fusarium wilt.

After less rain in autumn, the weather turns cool, general diseases are alleviated, and lawn rust is serious. For example, triadimefon can be used for prevention and control with the ratio of 1000- 1500, but it should be used alternately with fast-poly and thiophanate-methyl.

Three, road greening belt maintenance scheme

Hedgerow is a tree species with strong germination ability and pruning resistance. It is densely planted in strips, with separation function and beautiful shape. Such as Buxus macrophylla, Ligustrum lucidum, Berberis rubra, Sabina vulgaris, Buxus microphylla, etc. are commonly used hedge modeling tree species.

In recent two years, with the increase of colorful plants, color blocks composed of colorful tree species, such as: purple-leaf dwarf cherry, winter jasmine, forsythia suspensa, Tang Di, etc. , are commonly used tree species for environmental greening. But there are different pruning methods when pruning. The median of the road should be trimmed, with a height of 1- 1, 2m, which can block people's sight, and should be trimmed horizontally, vertically, neatly and beautifully. In order to make hedgerows flourish, different pruning methods are adopted because of different plant growth heights.

Road Greening Maintenance Plan (II)
