In the cold months of the year, the trees in the open area are dormant.

1. Winter pruning: comprehensively prune deciduous trees; Prune dead branches, disabled branches, pest branches and branches that hinder overhead lines and buildings.

2. Inspection of street trees: check the binding and piling of street trees in time, and rectify immediately if it is found to be loose, buried with lead wire and shaking piles.

3. Pest control: Winter is a favorable season to eliminate garden pests. The pupae and cocoons of moths can be dug up in the loose soil under the tree and burned to death.

February maintenance plan

The temperature has risen since last month, and the trees are still dormant.

1, maintenance is basically the same as 1.

2. Pruning: Continue to prune dead branches and diseased branches of large and small trees. Prune all kinds of trees before the end of the month.

3. Pest control: continue to control moths and scale insects.

March maintenance plan

The temperature continues to rise. After the middle period, trees began to germinate, and some trees blossomed in the later period.

1, green water:

1) Function: a Keep the soil moist and supply plants with sufficient water.

Prevent the spring breeze from drying up trees and sentries.

2) Time: generally from the beginning of March.

3) Standard: Water should penetrate into the lower layer where plant roots grow. The water seepage of lawn is about 15cm, and it is advisable to wet the trees at least half a ridge after water seepage.

4) Note: A Pay attention to the dead angle, and don't miss pouring.

B Because of the unstable temperature, the water pipes should be drained after each watering.

C spring irrigation should be carried out at the same time as pruning and fertilization.

2. Fertilization: In the first ten days of March, water and fertilization are coordinated. The tree-lined road improves the soil structure and increases the nutritional conditions for better growth of plants.

Fertilization of trees and shrubs: mainly nitrogen fertilizer (compound fertilizer, diamine, urea)

Lawn fertilizer, active urea, diamine. 5 5- 10/0g/m2. Times, not more than 25 grams/square meter. Time magazine.

3, pruning:

1) flowering shrubs: For branches that bloom in that year, they should be pruned again before flowering, such as rose, hibiscus and Lagerstroemia indica. For flowering biennial branches, they should be moderately pruned 1-2 weeks after flowering, such as: Yingchun, Purple Leaf Plum and Purple Leaf Dwarf Cherry. Look at the flowers and fruits, cut them lightly before flowers, such as apricot trees. Trim dead branches and cross branches at any time.

2) Pruning of big trees: Pruning of fruit trees and trees will be arranged this month.

3) Lawn: The first pruning can be carried out at the beginning of the month to remove hay from the lawn, stubble 4cm, and hold the dead leaves clean. Lawn grows slowly in spring, and it is trimmed 1 time a month.

4. Planting and fertilizing perennial flowers (Spiraea, Hemerocallis, Hosta, Iris, etc.). ) to make the ribbon neat and consistent.

5. Make statistics on dead seedlings and lawns, and arrange replanting in a unified way. Need a transplant.

6. Sanitation: Keep the site clean, especially the key sections and sections.

April maintenance plan

With the rising temperature, trees germinate, bloom or spread their leaves and begin to flourish.

1. Watering: Lawns and plants need a lot of water during the growing period. Continue to water a lot to ensure the normal growth of plants, prevent water waste, strictly control water consumption, ensure the normal growth of plants, and never water more.

2. Fertilization: basal fertilizer should be applied in spring to promote the growth of plant roots, thus promoting the growth of aboveground parts and laying a good foundation for the healthy growth of plants for one year, so it is necessary to seize the time to topdressing nitrogen fertilizer (diammonium) throughout the garden. (5 5- 10/0g/m2)

3. Pruning: firstly, mow the lawn once, then mow it every 10- 15 days when the lawn grows normally, with stubble of 5 cm; Ribbon hedges should be trimmed once before May Day to ensure the effect of the festival; Prune, thin and remove the core of flowering shrubs after flowering to promote the growth of branches.

4. Transplanting: The hedgerow area in the park is too large and can be transplanted. The removed open space is used to fill lawns or perennial flowers.

5. Pesticide application: Many pests can overwinter normally, so we should prevent them as early as possible and apply pesticides in time to prevent the spread of pests and diseases. This month, the website should organize a garden-wide disinfection.

6. Sanitation: strengthen sanitation management, including domestic garbage in lawns and hedges, and green garbage left after pruning.

May maintenance plan

The temperature rises sharply and trees grow rapidly.

1. Watering: This month, the trees enter the vigorous growth period, and the water demand is very high. Therefore, water should be watered in time to meet the needs of trees. Because the lawn has been watered after turning green, it has entered the normal maintenance period, pay attention to observation, find drought, and irrigate it in time.

2. Pruning: Prune the flowers and shrubs that have been pruned after flowering, cut off residual flowers, peel off tree buds and eliminate evil. Such as: apricot tree, red prince ribbon, Spring Festival couplets, etc. ; The lawn is growing very fast this month. In order to ensure the quality of lawn, the number of mowing can be increased appropriately. According to the growth of lawn, mow it 4-5 times a month with stubble of 5-6cm.

3. Pesticide application: organize a disinfection in the whole park. Carry out pest control on trees, and focus on preventing brown spot disease on lawns (from early May, once every two weeks +0.3% potassium chloride). Bactericide should be used to prevent diseases after each pruning. If the lawn is diseased, it should be treated in time, and the application frequency and concentration can be increased appropriately. Generally, trees mainly prevent American white moth. The main medicine is diflubenzuron. Dosage (1500-2000 times liquid) spraying. Flowering shrubs are mainly used to prevent tree lice.

4. Fertilization: If the lawn is mowed many times, it will easily lead to fertilizer deficiency, and foliar fertilizer can be applied to the lawn, mainly spraying potassium dihydrogen phosphate; Combined with irrigation and topdressing chemical fertilizer, topdressing can be carried out on weak trees, flowering shrubs, fruit trees, lawns and perennial flowers in mid-May; Potassium dihydrogen phosphate can be applied to the lawn under the big tree many times to help it spend the summer safely. Be careful not to fertilize immediately after mowing. Because the trees in the hospital are relatively large, it is necessary to cooperate with irrigation to apply chemical fertilizer to prevent the trees from aging prematurely.

5. Sanitation: strengthen sanitation management, including domestic garbage in lawns and hedges, and green garbage left after pruning.

June maintenance plan

heat up

1, watering: check trees, lawns, flowers and plants regularly, and water them in time when drought is found. Watering time should be chosen early or late.

2. Pruning: When the rainy season comes, you can appropriately prune the crown that is too large and too dense, and you can also prune some flowering shrubs (lilacs, purple leaf plums, etc.) after flowering. ). Due to the hot climate, the lawn gradually enters a dormant period, and the pruning height should be appropriately increased. The stubble height is generally 6cm.

3. Weeding: In order to increase the permeability of the lawn, change the microenvironment in the lawn and prevent diseases, pruning should be carried out after pruning. The general method is to mow the lawn once, then pour it again, or clockwise and counterclockwise.

4. Application: organize a disinfection in the whole park. Trees should be prevented from pests and diseases, and lawns should focus on preventing brown spot and noctuid. Fungal pesticides should be used to prevent diseases after each pruning and weeding, and organophosphorus or pyrethroid pesticides should be used. If there are pests and diseases on the lawn, pesticide treatment should be carried out in time, and the frequency and concentration of pesticides can be appropriately increased. When the pests and diseases are very serious, root irrigation can be carried out. Pay attention to the prevention and control of aphids and red spiders, and add a small amount of washing powder to pesticides.

5. Weeds: Use selective herbicides (superstars, etc. ) Clear the weeds in the green space in time in the lawn to prevent grass shortage.

6. Preparation for rainy season: As the rainy season approaches, the drainage ditch should be dug in advance to prepare for drainage and waterlogging prevention; In addition, do a good job of windproof.

3. Fertilization: Due to the hot climate, this month is not suitable for fertilization.

4. Pesticide application: organize a disinfection in the whole park. Lawn should focus on preventing brown spot disease, killing fungi and pesticides to prevent diseases after each mowing and weeding, and using organophosphorus or pyrethroid pesticides to prevent insects. If lawn diseases and insect pests occur, pesticide treatment should be carried out in time, and the frequency and concentration of pesticides can be appropriately increased. Root irrigation can be carried out when the pests and diseases are very serious. Spraying time should be chosen early or late.

5. Patrol and rescue: There are many storms in the rainy season, which are prone to dangerous situations such as crooked trees. In terms of labor organization, materials, tools, equipment, etc., make preparations in advance, check at any time, and deal with dangerous situations in time.

6. Weeds: Clear weeds in the green space in time to prevent grass shortage.

7. Loosening and punching: intertillage trees to loosen the soil to increase the air permeability of the soil; Punch holes in the lawn with hard soil and poor growth. If the weather is dry for a long time (10~ 15 days), the pine and cypress trees must be perforated and ventilated, and the steel drill should be used to drill more than 50cm along the crown drip line, and then flooded.

8. Sanitation: strengthen sanitation management, including domestic garbage in lawns and hedges and green garbage left after pruning.

September maintenance plan

The temperature dropped.

1. Watering: As the weather turns cold, the lawn gradually enters the recovery growth period. However, due to the decrease of ground transpiration, water can be controlled properly and saved.

2. Apply pesticide: The lawn is most prone to rust in September. First, pay attention to the growth and color of the lawn, control water at ordinary times, reduce the humidity of the lawn, pay attention to weeding after mowing, increase the air permeability of the soil, and apply triadimefon with the concentration of 1000 times, which can fundamentally reduce the possibility of lawn rust. If there are pests and diseases on the lawn, it should be treated with pesticides in time, which can be appropriate. Spraying time should be chosen early or late. Rust can be pruned first, and then treated with pesticides and nitrogen fertilizer. )

3. Pruning: stubble is left on the lawn for 5-6 cm; Prune dead branches, prune hedges, and arrange gardens in the green space to make the trees green and the gardens clean and tidy to welcome the National Day.

4. Fertilization: Nitrogen fertilizer can be continuously applied to promote the growth of plant roots.

5, weeding: completely weed before the National Day.

10 monthly maintenance plan

The temperature drops,1in late October, trees begin to shed leaves and gradually enter a dormant period.

1. Watering: 10 Pay attention to water control in the middle and early stages. Due to the weakening of surface transpiration, lawn and strip land should be controlled with water. Trees should pay attention to cultivating soil in the middle of water control, and pay attention to replenishing water under big trees.

2, pesticides: 10 The lawn is the easiest to rust. First of all, pay attention to the growth and color of lawn, control moisture, reduce the humidity of lawn, pay attention to weeding after mowing, and increase the permeability of soil, which can fundamentally reduce the possibility of lawn rust. If the lawn is not growing well and yellow spots appear on the leaves, it should be treated in time. First, the diseased leaves should be cut off, and then triadimefon with a concentration of 1000 times should be applied. Continue to prevent underground pests.

3. Fertilization: At the end of this month, the whole garden will be fertilized for the last time. Potassium dihydrogen phosphate and urea are mixed in a ratio of 1: 1 per square meter 10- 15g.

4, pruning:

1) Lawn pruning: As the temperature drops, the lawn gradually enters a dormant period and the growth rate slows down. So pay attention to the cutting time and increase the cutting time interval. Leave grass at least 6cm long at a time, and mow it immediately after mowing. Judging whether to water according to humidity. If the humidity is high, there is no need to water it, and then pesticide should be used to prevent rust.

2) Ribbon-cutting: All work should be completed before the end of 10.

3) Tree pruning: Pay attention to safety. When pruning, workers must wear safety belts and safety helmets, and the pruning work should be carried out under the guidance of the company's technicians.

5. Hygiene: In late autumn, a large number of fallen leaves are produced, so attention should be paid to cleaning them in time to keep the construction site clean and tidy.

5. Punch and loosen the soil: due to soil hardening, it is easy to make the lawn grow poorly, so pay attention to punching and loosening the soil.

1 1 monthly maintenance plan

At night, the soil began to freeze and entered the deep winter festival.

1. Watering: 1 1 month is the month when the land freezes, so a lot of watering should be started in the middle of 1 1 month until the light snow ends.

Standard: water at least three times at a time: the lawn should be frozen at least10-15 cm; This tree should be frozen for 50 cm.

B, visual inspection: after water seepage, the backwater is at least half a ridge wet;

C after backwater, the whole sole can be evenly wetted;

D. After the soil is frozen, the lawn is frozen to the surface, and the soil under other plants is frozen below 0.5-lcm.
