What are the maintenance and management of green seedlings in autumn?

The winter maintenance of garden trees directly affects the ornamental value and economic value of garden trees in the second year, as well as pests and diseases, and the following aspects should be noted:

1. Remove dead trees. Such as senescence, disease and insect infestation, man-made destruction, etc., causing some trees to die and destroying the overall landscape. Those irretrievable trees can be cut down as soon as possible and replanted with seedlings of the same size.

2. Fill frozen water in time. The entire life process of garden trees is inseparable from water. Although the evaporation in winter is small and the water requirement is relatively small, it affects the cold resistance and growth and development of garden trees in the coming year.

Therefore, in early November, the trees, especially the newly planted trees, should be irrigated with water, that is, "frozen water", and then combined with frozen water, a mound of soil should be cultivated at the base of the tree. This not only improves the water required by the tree itself, but also improves the cold resistance of the tree.

3. Apply rooting fertilizer. After the treetops stop growing in autumn, the root system has another growth peak. Therefore, depending on the age of the tree and the length of planting time in late autumn and winter, some organic fertilizer or chemical fertilizer should be appropriately applied, and at the same time, it should be mixed with the rooting agent of the happy forest, and the appropriate amount of irrigation should be irrigated to make the rooting fertilizer infiltrate, so as to promote the emergence of new roots, enhance the tree potential, and lay a good foundation for the growth and development of the next year.

4. Shaping and 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. This can be done around the time of the "winter solstice".

If the amount is large, it can be postponed to around the Spring Festival, 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, the ideal tree shape is cultivated, and for larger wounds, the callus is smeared with happy forest callus to protect them.

5. Paint the trunk white. 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. You can choose to use the white agent [brush type] or the white agent [spray type], which is convenient and simple to operate, and the effect is outstanding, and this work can be carried out in November.

6. Clean up weeds and fallen leaves. Weed litter is not only a wintering place for certain pests and diseases, but also cleans up the weeds and leaves in the green space and treats them in a centralized manner, which not only eliminates the source of pests and diseases, but also eliminates the fire hazard.

What are the specific management measures for seedlings?

1. Arbor maintenance.

The standard of arbor management and maintenance: it is vigorous growth, strong branches and leaves, beautiful tree shape, neat lower edge line of street trees, moderate pruning, beautiful trunk and straight crown, no dead trees and missing plants, no dead branches and residual leaves, and excellent landscape effect. The details are as follows:

1) The growth potential is strong, and the growth exceeds the average annual growth of the tree species; The branches and leaves are strong, the branches are stout, the leaf color is dark green, and there are no dead branches and residual leaves.

2) Pruning: Arbor pruning mainly removes long branches, diseased and insect branches, cross branches, drooping branches and dead branches.

3) irrigation, fertilization requires the application of organic fertilizer twice a quarter, the use of hole application and spraying, water and fertilizer, etc., and then covered with soil, drenched thoroughly, water penetration depth of more than 10 cm, no need to shape pruning trees, timely pruning of yellow branches, diseased branches, shade branches and obstruction of vehicle traffic drooping branches, timely clean pruning materials. And it is required to focus on fertilization 4 5 times per quarter in spring and autumn every year. In November and December, water the wintering antifreeze water in time, and do a good job of supporting the wind barrier.

4) Do a good job in the prevention and control of pests and diseases in a timely manner, focus on prevention, carefully manage, so that plants can enhance their ability to resist pests and diseases, check frequently, and detect and treat them early.

5) Remove snow from branches in winter in time, and there is no snow bending, crushing, and crushing of branches.

2. Maintenance of shrubs, hedges and lawns.

Shrubs, hedges, lawn maintenance standards: is vigorous growth, strong branches and leaves, normal color, moderate and neat pruning, dry straight crown beauty, no dead seedlings and missing plants, no dead branches and residual leaves, excellent landscape effect. There are no weeds in the lawn. The details are as follows:

1) Loosen the soil, hoe the grass, and fully level it after the spring of the next year. For all kinds of weeds with strong vibrancy, once discovered, immediately **.

2) Pruning and shapingThe main purpose of pruning and shaping seedlings is to ensure the normal growth of seedlings and improve ornamentality. Shrub pruning is mainly to preserve the natural tree shape; Hedges, spherical plants are mainly pruned. Pruning is generally carried out in the dormant period in autumn, and shaping is mainly carried out before the germination of seedlings in spring.

The height of the stubble on the lawn is generally controlled at about 10 to 15 cm.

The specific management measures for seedlings are as follows: drought prevention and flood prevention: if there is dry weather, irrigation should be carried out in time.

The irrigation of seedlings in the fast-growing period should be done more and more times, and each time it should be watered thoroughly and evenly, and try to avoid watering at noon when the sun is the strongest (especially small seedlings, newly planted seedlings and ground cover plants). At this time, it is also a shower-prone period, and the ditch drainage work should be done in time before and after the rain. Weeding:

Summer is the vigorous period for the growth of weeds in the field, and we must do a good job of weed cleaning plan, and we should try to achieve the principle of "early, small, and except". Combined with some contact herbicides to achieve the purpose of controlling weeds in the field.

As an operator, before operating a nursery, the nursery must be roughly divided into functions. Only in this way can we achieve a targeted effect, so as to achieve twice the result with half the effort, according to my many years of nursery management. We might as well divide the nursery into the following types:

Propagation nursery: simply as the propagation of seedlings and flowers, this kind of nursery has strict requirements for the physical and chemical properties of the soil and the geographical location. It is mainly used to plant seedlings.

Planning in terms of comparison next to the management room. Medium nursery: mainly used for transplantation and cultivation of forming seedlings, this kind of nursery has a long production cycle and slow effect.

The requirements for the physical and chemical properties of the nursery soil are not very strict. However, it is not suitable for places where water is stagnant. Big Stump Scenic Area:

The main thing is to buy some native tree varieties and transplant them two to three years before going to the construction site. This area should be located next to the highway where people and cranes can enter. Color-block seedlings and spherical seedlings:

The planning period of this kind of nursery is relatively short, and the location of the lower nursery area can be appropriately selected, which is suitable for the water supply of color block seedlings, and spherical trees can be interplanted under large trees.

1. Timely irrigation: the method of watering seedlings in the fast-growing period should be more and less;

2. Remove weeds: most of the nursery furrows are covered with plastic film to pull out weeds;

3. Waterlogging prevention: There is more rain in autumn, once the seedlings are flooded, it will cause the bark to crack and die;

4. Scientific top dressing: in autumn, farmhouse fertilizer and compound fertilizer are mainly applied;

5. Control lateral roots: for broad-leaved cuttings, it is necessary to control their few lateral roots; Stuffy oak.

6. Disease prevention and insect control: the nursery should do a good job in the prevention and forecasting of pests and diseases, and timely prevent and control the diseases and pests that have occurred;

7. Whitening: whitening the branches with whitening agent can reduce the freezing of the sunny side of the seedlings due to the large temperature difference between day and night;

8. Wrap straw: roll dry with straw rope or wrap the main trunk and part of the main branch with straw;

9. Remove diseased fallen leaves and branch insect cocoons: For the early fallen leaves caused by disease, the nursery should be thoroughly cleaned out;

10. Spraying prevention: before the trees fall leaves, spray the antifreeze of the happy forest 3-5 times.

1. Soil requirements.

Soil preparationIn landscaping projects, there are no strict requirements for seedling species, but there are certain requirements for soil selection. The pH of the soil in which seedlings are planted must be controlled within a reasonable range. Saline-alkali land or heavily polluted soil should not be planted with seedlings.

If the soil does not meet the requirements, it can be appropriately improved. In addition, seedlings also have requirements for soil hardness, and only soil hardness that meets the requirements can promote the growth of seedlings.

2. Water quality requirements.

Water quality preparationAfter seedlings are planted in the soil, water supply becomes one of the key tasks. When planting, it is necessary to scientifically plan the watering time of seedlings. The watering plan should be formulated according to the growth cycle and growth characteristics of various seedlings.

The requirements for water quality of urban greening garden seedlings are not strict, as long as the water quality is not polluted, and the acid-alkali salt content of the water quality should not be too much.

3. The purchase of landscaping seedlings.

Seedlings should be purchased for urban greening, and seedlings with good root growth should be selected, which grow well and are easy to manage. At the same time, when selecting seedlings, it is necessary to comprehensively consider various factors such as seedling growth, disease and pest resistance, and green belt design, and try to select young and middle-aged plants. In order to facilitate later pruning and design, a slightly larger plant size than the design size can be purchased.

The management measures of seedling maintenance technology are the key factors to ensure the healthy growth or development of seedlings. The following are some commonly used seedling maintenance technical management measures:

Irrigation: According to different plant requirements, timely irrigation, and if necessary, add nutrient solution and other operations.

Nutrient management: Giving plants enough nutrients can promote the growth of flowers and plants, and appropriate fertilization can be applied according to plant species, different growth stages and environmental conditions to supplement the nutrients required by plants.

Temperature management: Different seedlings have different temperature management requirements. It should be noted that on cold days, the stool returns to the seedlings with a protective layer to keep them warm.

Pest control: The control of pests and diseases is an important aspect of seedling maintenance. Regular weeding, removal of weeds and dead leaves, removal of infected plant parts, etc., are also important means of reducing pests and diseases.

In conclusion, the management measures of seedling maintenance technology are very important and must be effectively managed according to the characteristics and growth status of each variety. Only scientific and reasonable management methods can ensure the healthy growth and development of seedlings.

<> seedling maintenance needs to be turned over the ground once before winter to remove weeds; The newly planted seedlings need to be pruned and shaped to promote the recovery and growth of the seedlings. Half a year after planting, apply root fertilizers such as urea, tomato, and hefei; Spray regularly before the plum season to control pests and diseases, remove the dead seedlings, and make up the original position to plant the seedlings; For the subsidence and uneven parts of the soil, soil is added, and terrain restoration is carried out during the celebration of the trembling acacia.

Landscaping measures include:1Rational selection of plant varieties, according to different environmental conditions to choose suitable seedlings.

2.Reasonable design of plant configuration is round, avoiding large-scale planting of a single plant species, and improving the landscape effect. 3.

Give the seedlings adequate maintenance, including watering, fertilizing, pruning, etc. 4.Timely detection of seedling diseases and pests, take corresponding control measures.

5.Strengthen greening management, keep the site clean and tidy, and clean up fallen leaves and weeds in a timely manner. 6.

Plant plants suitable for local climate and soil conditions to avoid the introduction of exotic species. 7.Adopt biodiversity conservation technologies to increase the protection and improvement of the ecological environment.

8.Pay attention to water saving and energy saving in the greening process, and choose low-energy-consumption, environmentally friendly greening equipment and equipment.
