What should be paid attention to if you want to maintain greening?

Trees must be protected during transportation, especially in some places that are far away, and it takes a few days during transportation, such as to prevent mechanical damage to the trunk and bark, etc., and straw bags should be used to protect them. It is best to choose plants with a wide range of planting seasons, so as to effectively prevent some plants from being planted in non-planting seasons, thereby greatly reducing their survival rate. In the process of planting, plants need to take certain effective measures on the topsoil of the soil, such as the soil particles in the soil should preferably form an aggregate structure.

Because the size of the aggregate suitable for plant growth is 1 to 5 mm, the pores are less than a millimeter, and the root hairs cannot invade. In general, the topsoil has a large amount of nutrients and useful soil aggregate structure, but often in the construction of garden engineering, it will cause the topsoil to be stripped due to the transformation of the terrain, and in this case it is not conducive to the growth conditions of the plant, so it is one of the simplest and most effective methods to save the original topsoil, and at the same time in the planting process, it should also be noted that heavy machinery can not enter the planting site to compact the soil, and the aggregate structure is destroyed, it is best to use a regressive forklift to dig the topsoil, and proceed in one direction, It is best to lay the topsoil directly on the site where it is intended to be planted.

Finally, it can be said that in the planting content of garden engineering plants, it is also necessary to be familiar with the root coverage and depth of plants. For example, the minimum thickness of lawn and ground cover root zone layer is 375px, 750px for small shrubs, 1125px for large shrubs, 1500px for shallow root trees, and 2250px for deep root trees. On the basis of the minimum thickness of survival, the minimum thickness of plant cultivation increased by 375 px for lawn ground cover and shrubs, 750 px for shallow-rooted trees, and 1500 px for deep-rooted trees

And so on, there are many things to pay attention to in the planting of plants, such as the hardness of the soil, clumps, etc., only in each link are noticed, then the survival rate of the plant will be greatly improved, so as to effectively reduce the repeated cost generated in the landscaping project.

First, the turf, to be regularly mowed, according to different seasons, growth, reasonable arrangement of the pruning period, to the grass length does not exceed 10 cm shall prevail, generally 5-9 months about 25-30 days of mowing, 3-5 months and 9-11 months 35-40 days of mowing, (northern region) December of the year to February of the following year in principle do not mow, after mowing the lawn surface level height of about 3-4 cm. Fertilize the turf once after each mowing and water it thoroughly after application to ensure that the turf is evergreen all year round. Every time the turf is inspected, the weeds are removed in time, so that the purity of the lawn is controlled at 95% in the excellent community and more than 90% in the general community.

Pick up rocks, confetti and other debris in the grass and flowers. 2. Hedges, stereotyped plants, before the hedge grows before it is formed, it is mainly pruned with dense branches, and after it is formed, it is mainly pruned by modeling. The pruned hedge surface should be smooth, smooth and straight, the hedge shape plant shape is beautiful and rich, and the pruned branches and leaves should be removed immediately.

After modeling, the branches that grow beyond the hedge should be cut off in time, and the length of the branches beyond the hedge should be controlled within 10 cm. The seedling retention rate of hedges is 95%. The incomplete or dead part should be replanted within a month Hedges and modeling plants should be applied with nitrogen fertilizer every 50 days from March to August every year, and compound fertilizer should be applied once every 40 days from September to November, and the amount of fertilizer per mu is 15 catties.

3. Trees and shrubs should be inspected every week, and dead branches, diseased and insect branches, overlord techniques, and drooping branches should be pruned in a timely manner. Prune branches and leaves should be removed immediately. According to the growth of the shrub, the shape should be modeled in time; After modeling, it is advisable to prune the branches and leaves beyond the shape in time, generally to control the length of the branches and leaves outside the shape not to exceed 20 cm.

The tree maintenance rate of the lamp road should reach 98%, the trunk is thick, the pruning is timely, and the height of the trunk is generally controlled in meters. The branches are reasonable, the body of the tree is straight, and the branches and leaves are luxuriant. Generally, compound fertilizer is applied once every two months to ensure vigorous growth.

For large trees that grow luxuriantly, fertilizer can be omitted. Fourth, watering, outdoor greening should be based on different seasons, weather, different plant varieties growth habits, different cultivation purposes, different soils every day, every other day or a few days to water once. When there is a lack of water due to hot and dry weather, the frequency of watering must be increased accordingly to ensure that all plants do not wilt due to lack of water.

In the fine season, outdoor potted plants are watered once a day; Water once every 3-4 days when planted at the base of the flower, and do not water it on rainy days; Indoor potted plants are watered 2-3 times a week.

5. Plant reserves, focusing on prevention, comprehensive prevention and control, diligent observation, early detection, and early prevention and control. The use of pesticides must be based on the premise of not harming health, and the use of high-efficiency, low-toxicity, odorless, and odorless pesticides must be used. When spraying pesticides, you must wear a mask, safety gloves, and long-sleeved clothing.

Smoking and eating are prohibited. People should stand above the incoming wind to prevent the spray of pesticides from blowing back into the human body and causing poisoning. After spraying pesticides, wash your hands with soap and running water several times.

The main items are as follows: strengthen the prevention of pests and diseases (do not think that in winter, pests and diseases will not occur). We can make predictions in advance by careful observation; For the lawn:

The warm-season ones have turned yellow, so just make sure it's moist. For cool-season lawns: Although the lawn is still green, it is important to keep an eye on the growth; For all kinds of tropical plants (different regions), strengthen the insulation work.

Although winter insulation has been carried out, it is necessary to strengthen observations. Don't let the wind blow; For flowers in the flower beds: You can choose some grass flowers that are suitable for the season (kale.

pansy, morning glory, etc.) to save costs; For shrubs: the general wax plum blossom, according to the change of weather, should start to bloom, hehe, but the flower is not yet fragrant; For plants that are evergreen all year round: intensify observations.

If snow is found, it should be cleared in time to avoid shortening the branches; For ancient and famous trees: because they are living fossils, they should be more concerned. For specific projects, you can consult relevant technical personnel; Other garden maintenance items, such as lawn can be soiled, plane trees, willows, etc. should be pruned.

I think it's better if there's a lot of sunshine, and if it's watery, it should rain.

Due to the different regions of Gaohui, they are also different in meteorology, and practical work is carried out for different regions. But the main plan is regular, and the main ones are as follows:

1.Strengthen the prevention of pests and diseases (do not think that in winter, pests and diseases will not occur). We can make predictions in advance by careful observation;

2.For lawns: The warm season has already turned yellow, so just make sure it's moist. For cool-season lawn: Although the lawn is still green, keep an eye on the growth.

3.For all kinds of tropical plants (different regions), strengthen the insulation work. Although winter insulation has been carried out, it is necessary to strengthen observations. Don't let the wind blow;

4.For flowers in the flower beds: You can choose some grass flowers that are suitable for the season (kale. pansy, morning glory, etc.) to save costs;

5.For shrubs: the general wax plum blossom, according to the change of weather, should start to bloom, hehe, but the flower is not yet fragrant;

6.For plants that are evergreen all year round: intensify observations. If you find that there is snow, you should clear it in time to avoid shortening the branches.

8.Other garden maintenance items, such as lawn can be soiled, plane trees, willows, etc. should be pruned.

Landscaping should pay attention to more, garden engineering includes landscape management, transformation of terrain, construction of roads, paving of sites, construction of buildings, construction of engineering facilities, greening and planting and many other contents. From the design to the construction stage, it focuses on the landscape effect after completion, and the overall goal is to create a good living environment for animals and plants, and create a garden-style green space.

Now the scale of landscaping projects is becoming larger, and in actual operation, the garden projects are often divided into several parts, which are entrusted to different units for construction, so there are often problems in the connection of projects and construction coordination. In addition, due to the special needs of some projects, it is common for plants to be planted in non-planting seasons. Through practice, the author puts forward the following several problems that should be paid attention to in the process of garden construction for reference by peers.

1.Preservation of the original treesThe original trees need to be preserved, and measures should be taken to temporarily fence them off before civil construction to avoid damage caused by solidity and burning. In order to prevent mechanical damage to the trunk and bark, grass bags should be used to protect it.

In particular, street trees sometimes need to be cushioned due to the replacement of pavement boards or tree hole boards, and lime and cement will cause soil alkalinization, which will endanger the normal growth of trees. Therefore, during the construction process, the tree hole is first protected with soil to make a mound with a height of less than 30 cm to avoid lime invasion. If the cushion needs to be watered and maintained, the tree hole should be enclosed in time, or the water should be directed elsewhere, and it is forbidden to pour water containing lime and cement into the tree hole.

2.The topsoil is taken and restored, and the soil is the basis for the growth of flowers and trees, and the soil particles in the soil constitute the aggregate structure. The size of the pellet suitable for plant growth is 1 to 5 mm, less than the pores of the millimeter, and the root hairs cannot invade.

In general, the topsoil has a large amount of nutrients and a useful soil aggregate structure, and when the terrain is transformed, the topsoil is often stripped away, which can not ensure that the plants have good growth conditions, so the original topsoil should be preserved and effectively used when planting.

In the process of taking and restoring the topsoil, in order to prevent heavy machinery from entering the site to compact the soil and avoid the destruction of the aggregate structure, the topsoil is excavated by a reversing forklift, and carried out in one direction, and the topsoil is directly tiled on the predetermined planting site, and is not temporarily stacked to prevent surface consolidation. Excavation and tiling of topsoil operations should not be carried out after rain, and the ground conditions during construction should be very dry, and the machinery should not be repeatedly rolled. In order to avoid the formation of a stagnant layer on the restored ground, tiling should be done well.

Extended information: Landscape engineering includes landscape management, terrain transformation, road construction, site paving, building buildings, construction of engineering facilities, greening and planting, etc. From the design to the construction stage, it focuses on the landscape effect after completion, and the overall goal is to create a good living environment for animals and plants, and create a garden-style green space.
