When the temperature is low and low, the precautions for greening maintenance

Attention should be paid to taking cold-proof measures for cold-intolerant plants, such as soil piles, poles, wind shields, etc.

Snow can be piled up on the roots of plants after snow, but the snow must not contain deicing agents.

In the northern region, there will be windy weather in winter, so it is necessary to take support measures for the newly planted plants in recent years and comb the dead branches on the large trees.

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 looking carefully.

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.).

5.For shrubs: the general plum blossoms, depending on the change of weather, should start to bloom, hehe, but the flowers are 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.

In July (light heat, big heat), the minimum is 26°C, and the maximum is 35°C

1. Wind and waterlogging. In the summer season, strong winds are frequent, and storms are also increasing, so it is necessary to pay attention to the weather forecast and grasp the situation of heavy storms and rains. Do a good job of righting and reinforcing the tree support facilities, and at the same time thinning the trees (thinning some of the overly dense branches to increase ventilation and reduce the resistance of the ground wind) and soil cultivation.

2. Watering. After 4 p.m. and before 10 a.m. every day, it is not dry or drenched, and it must be drenched thoroughly, and those who are not resistant to drought should be drenched more. Chemical and manual control of weeds.

3. Pruning. Cut off the dead yellow leaves and residual flowers of natural aging on the ground cover, prune the modeling plants, prune the shape and lawn, and prune the color block balls.

4. Pest control.

In August (the beginning of autumn and the beginning of summer), the lowest is 26°C, and the highest is 31°C

1. Watering. In autumn, the air is still very dry, and when the temperature is high, water the less drought-tolerant plants (mainly the trunks and branches). Chemical and manual control of weeds.

2. Increase fertilizer. After several months of vigorous growth and development, many plants gradually deplete nutrients and need to be supplemented with organic fertilizers or chemical fertilizers. For the plants that bloom again, it is necessary to spray the leaf falling fertilizer to meet the needs of buds; At the same time, it is beneficial to the growth of autumn buds and the rejuvenation of plants (Yueji, etc.) that have been cut off and withered flowers.

3. Pest control. This month the weather is still relatively hot, and there are more storms, so it is necessary to spray the disease-prone plants as soon as possible after the rain to control the breeding and spreading of pests and diseases. There are mainly canna, grass along the steps, etc.

For some newly transplanted trees, it is necessary to check whether there are main pests such as longhorn beetle at the cutting point.

4. Modeling pruning of shrubs and pruning of lawns.

September (white dew, autumn equinox) minimum 23°C, maximum 33°C

1. Watering. In addition to watering and moisturizing, it is also necessary to regularly do a good job of flood prevention and cleaning of drainage ditches.

2. Pest control. This month, there are many pests and diseases such as red spiders, scale insects, beetles, whiteflies, leaf blight, etc., so they must be sprayed 2-3 times in time.

3. Pruning and top dressing. Autumn shoots have begun to draw, and some shrubs have been depleted of nutrients after flowering some time ago. It must be pruned and top-fertilised as soon as possible to bring the plants back to life and grow faster. Modeling pruning of shrubs and mowing of lawns.

4. Chemical control and manual control of filling and spreading grass and weeds for obvious potholes on the lawn.

Isolation zone greening trees can not only be used on the road to isolate car driving, but also play a very important role in beautifying the environment and improving air quality.

The first wrap around the trunk is a good measure. For example, the street tree wraps the trunk with the material cloth for the winter cold-proof treatment of the deciduous tree of the tung tree, wraps the trunk tightly, and then wraps it with a straw rope to moisturize and prevent the cold, and then uses the mulch film to keep the roots of the tree warm and cold-proof, so that the survival rate of the tung tree in the following year reaches 99%.

The second is the application of whitening agent for tree trunks. Whitening the trunk in winter can not only reduce the damage caused by the large temperature difference between day and night on the sunny side of the bark, but also eliminate the diseases and insects that overwinter in the cracks of the bark. On this road, I recommend a happy forest spraying whitening agent that can be sprayed and easy to apply, which greatly improves the labor efficiency, and saves medication and has a good effect.

Third, it is necessary to fill and seal frozen water in time. When the soil around the seedlings is short of water in winter, it is easy to freeze damage, so it is necessary to fill the frozen water in time before the soil is frozen. In addition, the specific heat of water is larger, which can absorb more heat during the day and increase the ground temperature.

Fourth, we should increase the application of organic fertilizer, dig 3 to 4 holes 50 to 100 cm deep in the periphery of the canopy, and apply horse manure, grass and other hot fertilizers to increase the ground temperature. Organic manure decomposition releases heat and increases soil fertility. Combined with fertilization, the plants should be cultivated to cover the root neck to form a small conical mound, which can protect the root neck that is prone to frost damage and overwinter safely.

The fifth is plastic pruning. According to the different application purposes of garden trees, correct shaping and pruning can not only adjust the shape of the tree, but also coordinate the relationship between the aboveground and underground parts, promote flowering and fruiting, and eliminate pests and diseases. According to the growth characteristics of the tree, the dead branches, weak branches, diseased and insect branches are cut together, and the overgrown branches are appropriately retracted, the ventilation and light transmission conditions inside the canopy are improved, and the ideal tree shape is cultivated.

The sixth is to spray antifreeze. It can be diluted 500-800 times by military training spraying plants with antifreeze agent of happy forest, sprayed 3-5 times, with an interval of seven days each time, and the antifreeze factor can be formed in the tree after application, improve the degree of lignification, increase hot spots, and significantly improve the frost resistance of plants to low temperatures.

1.Many plants are still growing in autumn and winter, but conservation management should be appropriately changed.

2.When maintaining plants in autumn and winter, you should water it in time, and do not water it when the soil is not dry, so as not to produce water in the soil.

3.It should also be properly exposed to the sun, the general plant is afraid of strong light, but in autumn and winter, you can fully see the light.

4.In addition, the plants should be moved indoors in time after winter.

In winter, the soil is easy to dry and compact, so it should be watered in time. Prune the hedges, and clean up dry branches and leaves, yellow leaves, dead branches, etc. in time. When encountering compacted soil, the soil should be loosened to increase the permeability of the soil.

Ground cover conservation.

Pay attention to observe the insect pests in the grassland, especially grubs and armyworms, and spray a broad-spectrum insecticide on the area prone to insect infestation; Prevent pests from harming the meadow. Remove obvious weeds, and spray more serious broadleaf weeds evenly with selective herbicides. Mow the lawn once and keep the growth height within 5cm; Make the lawn achieve the best viewing effect.

In the dry season, do a good job of daily cleaning and watering. Since this month, we have started to follow up on the cutting of grass fields, requiring that the curbs are not encroached upon, and the edgelines are neat and smooth.

Heavy snow winter solstice (December).

Arbor maintenance.

Evergreen trees and shrubs need to be pruned in winter. Eradicate overwintering pests. Prepare for next year's adjustment: After the deciduous plants have fallen their leaves, observe the conservation area and draw the direction to be adjusted.

Ground cover conservation.

Before the arrival of severe cold, for some evergreen, open ground overwintering but susceptible to frost damage in advance to do anti-freezing work, generally sprinkle sawdust on the ground, or cover the low dead plants with a layer of rice or appropriate watering to prevent freezing. The roots and flowers that have been removed from the branches and leaves are fertilized with well-rotted organic fertilizer on the root neck soil to promote the tillers to sprout and grow in the next year. In the woods with low planting density, deep ploughing between plants is applied thick fertilizer.

Big and small cold (January).

Arbor maintenance.

At this time, to prepare for the beginning of spring, it is necessary to prune deciduous trees comprehensively; Prune dead branches, broken branches, diseased branches and branches that prevent overhead lines and buildings from large and small trees. Inspect the street tree binding and pile erection in time, and immediately rectify the situation when the pile is loosened. Winter is a favorable season to get rid of garden pests.

The pupa of the stinging moth can be dug up in the loose soil under the tree, and the cocoons can be burned to death. In mid-January, scale insects start to move, but they are sluggish and we can scrape the larvae off the trunk. Pest control in winter has twice the result with half the effort.

Ground cover conservation.

The vast majority of the ground cover is dormant or semi-dormant. For semi-evergreen species with a long leafy period, the yellowed aerial parts are cut off in early January after the seeds are ripe and harvested in December. For land ready for planting ground cover, use this time to apply organic fertilizers such as river mud on the basis of autumn ploughing.

Woody dwarf shrub ground cover can be fertilized in winter. In the case of excessively dry ground cover in January, flowering in spring and germinating in early spring is susceptible to freezing, it should be watered appropriately at noon on a sunny day. Combined with winter fallow to add soil or ditch to poorly drained ground cover planting land.

In summer, special attention is paid to the following:

1. Watering: drought resistance, drainage;

2. Pruning: mainly the pruning of lawns and flowers;

3. Pests and diseases: summer weather conditions are easy to cause frequent pests and diseases;

4. Emergency: timely inspection and risk removal after the wind and rain.

Pay attention to watering on time in hot weather!

The content of greening and maintenance mainly includes the following points:

1. Pruning (divided into winter pruning and growing season pruning).

Winter pruning is carried out before germination, avoiding low temperature weather, and the pruning amount is relatively large due to interception and thinning. Pruning in the growing season is mainly based on budding and pruning long branches.

2. Watering. Water once after the beginning of spring and once before the soil freezes. In the rest of the season, it is more appropriate to replenish water in time according to the weather conditions, and it is more appropriate to avoid high temperature periods in the high temperature season and choose to water in the morning and evening.

3. Pest control. Before the beginning of spring, spray Bordeaux sap on disease-prone plants in advance for control, and in winter, the trunk can be painted white. There are many pests and diseases in summer and autumn, and the occurrence of specific pests and diseases is carried out according to the actual occurrence.

4. Fertilization and loosening of soil. It is mainly carried out in winter with loosening soil.
