How to do a good job in the maintenance of landscaping plants in autumn and winter

In autumn and winter, the weather is getting cooler, the temperature drops, the air is dry, many green seedlings have entered the dormant period, and the growth activities are not as vigorous as before. So what should be done on seedlings in autumn and winter?

1. Stop measures to promote the growth of the upper part of the seedling. During this period, it should be strictly forbidden to chase fast-acting fertilizer to prevent seedlings from growing. However, phosphorus and potassium fertilizers can also be added to promote the lignification of seedlings and the formation of robust spores.

During this period, foliar sprays can be carried out every ten days to half a month with potassium dihydrogen phosphate of Chunyu No. 1+ from September, three times in a row. Or apply 4-5 quintals per mu with plant ash each time, twice in a row. Foliar boron spray to improve cold resistance.

From September, the borax liquid of Chunyu No. 1+ will be sprayed every 10 days or mixed with potassium dihydrogen phosphate. Squirt three times in a row.

2. Clearing garden management. In autumn and winter, the nursery should be comprehensively cleaned and organized, dredged and excavated drainage and irrigation ditches, combined with pruning and pruning, pruning dead branches and diseased and insect branches, and at the same time uprooting dead plants and cleaning up dead branches and weeds in the nursery. Strengthen the prevention and control of pests and diseases, and carry out comprehensive pest control with Baume 2-5 degree stone sulfur mixture in the whole garden during the dormant period.

3. Do a good job of cold protection and cold protection measures. The specific measures are as follows:

Irrigation to prevent freezing. On the eve of frost, the nursery is irrigated, which can make the soil temperature not lower than 0 and protect the seedlings from freezing to death.

Smoke to protect against cold. In particularly cold weather, you can set up 2-3 smoke piles around the nursery, light cigarettes when the temperature drops to 0, and keep the smoke until sunrise.

Mulching: mostly used for flowers in the open field of the nursery, before frost, covering hay, straw mats, etc. on the ground, this method is both economical and good, and the application is extremely common. In addition, it can also be covered with materials such as plastic film, but it needs to have certain economic conditions.

Trunk protection: Trunk wrapping and whitening are common. 1.

Trunk wrapping: Mostly carried out before winter, the trunk of newly planted trees or cold-tolerant varieties is wound or wrapped with straw rope or sack sheets, etc., and the height can be up to about 2 meters. 2.

Whitening of the trunk: Generally carried out in autumn, the trunk is whitened with the whitening agent of the happy forest, and the white reflects the sunlight to reduce the absorption of solar radiation heat by the trunk, thereby reducing the temperature difference between day and night of the trunk and preventing the bark from freezing. In addition, this method also has a certain effect on the prevention of pests.

Spraying happy forest antifreeze: before the autumn leaves fall and after the fruit is picked, all kinds of greening trees and shrubs can be sprayed with "happy forest antifreeze" 3-5 times, so that the trees themselves can improve their ability to resist stress and frost, so as to prevent frost damage.

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.

Illumination. Cultivating ornamental fruit plants needs to have sufficient light, and it is generally necessary to place them in a sunny place so that they can be exposed to sunlight. In winter, if you want to cultivate ornamental fruit plants indoors, you need to keep enough light and try to contact the sun to enhance the ornamentality.

Airy. Ventilation of the environment is very important for fruiting plants, and maintaining air circulation can prevent the fruit from falling off early because it is too stuffy.

Temperature. According to the cold tolerance of the plant, determine what kind of temperature is needed to maintain the ornamental fruit plant in winter. For non-cold-tolerant ornamental plants, the maintenance temperature needs to be kept high, more than 15 during the day and 10 at night, such as bergamot.

The more cold-tolerant ornamental fruit plants can tolerate low temperatures, and the temperature at 0 may not have a big effect, such as wolfberry.

Watering. In winter, it is necessary to pay attention to the moisture that cannot be ignored. If the plant already bears fruit, then keep the potting soil moist, the fruit contains thick water, it will look full, more beautiful, if there is no water, the fruit may lose water and dry up.

Fertilize. In fact, after applying a water-soluble fertilizer before winter, it is best not to fertilize it to avoid fruit drop.

In the spring season, landscaping maintenance is a matter that is valued, landscaping, purifying the environment, and establishing a green ecological beauty must gradually start from spring. Integrating the key points of spring maintenance, the details are now as follows: Greening seedling replanting:

Greening seedling replanting is one of the contents of spring landscaping maintenance. Due to a cold winter, some of the green seedlings in the landscaping belt during the winter will always have some withering and dying. Therefore, the first thing is to seize the beneficial opportunity of spring to carry out replanting and replacement.

Soil, fertilizer and water management is an important part of the management method of green seedlings. Because of the drought in the spring, the temperature rises and <>

The evaporation of water surface is large, and soil management methods must be done well, and measures such as soil cultivation should be used to loosen the topsoil of green seedlings, improve permeability, and avoid secondary salinization of soil. Pest control: create rules and regulations for the analysis of pests and diseases, meteorological forecasting, and assign special personnel to be responsible for observation and testing.

Integrate the laws and habits of various pest hazards, scientifically and reasonably formulate prevention plans, ensure early detection and early remediation, and ensure the healthy and happy growth of greening seedlings. In spring, a comprehensive inspection of pests and diseases will be carried out on green plants, eliminating dead trees and green seedlings with serious damage in greening, digging out winter insect pupa, and shaving old rough bark before budding. For the roots, <>

The bulb must be upgraded to promote the roots, and the plant or the underground part can be dug up from February to early March, cutting, and the planting area can be fertilized and replanted. At the same time, expansion planting can also be carried out for excess planting. The planting of bulbs and ground cover plants such as allium orchid and leek can be carried out from the beginning of the month.

The missing plants need to be replanted immediately in the middle and late middle and late months to facilitate consistent plant growth. In the hot summer, the water loss of the plant community is more serious, and in order to maintain the water balance of the plant community, it is necessary to fully water the landscaping. In addition, continuous high temperature is easy to cause serious pests and diseases, and it is necessary to carry out spraying of pesticides on plant communities; Precipitation in summer is more colorful and <>

It is necessary to do a good job of the corresponding drainage pipes to avoid drowning in the plant community due to too much rainfall. After the second shedding of the skin, the scale insects were successively transferred to the crevices of tree roots, bushes, the bottom of tree poles, and the foot of the wall to metabolize milky white fruit wax and pupate into thin cocoons. It can be solved with a hard bamboo broom, and then concentrated burial or soaking.

Or choose the method of spraying chemical fertilizers such as pine borer. Scientific and reasonable watering can ensure the excellent development of plants, if the soil moisture content is too much, the plant roots will rot, resulting in the death of green plants. The operator requires that the construction application of the drainage ditch be handled in combination with the local natural conditions and reasonable irrigation.

First of all, you should water enough, and in the spring, try to water it 1-3 times. The second is to ensure that the fertilizer is sufficient, and the second is to prune the excess branches and leaves to ensure the adjustment of the tree structure.

Be sure to water in time, prune the branches and leaves regularly, don't let the branches and leaves be too vigorous, ensure the moisture of the soil, and prevent pests and diseases in advance.

In order to make the various garden plants planted not only survive and grow, but also grow better and more beautiful, it is necessary to formulate realistic and scientific conservation measures according to the biological characteristics of these plants and the specific conditions of the local area.

1. Irrigation: Different kinds of garden plants have different requirements for water in different periods, and irrigation should be carried out according to the different needs of plants

1) For newly planted trees, irrigate at least 6 times a year, that is, in November, during a period of time when new trees are planted in spring, they should be irrigated every 1-2 days.

2) Drought-tolerant species have less irrigation and vice versa. Fill with water thoroughly.

2. Plastic pruning: In addition to regulating and controlling the contradiction between the growth of garden plants and flowering and fruiting growth, senescence and renewal, the important thing is to meet the requirements of ornamentation and achieve the effect of beauty.

For species that flower first and then leaves, you can prune the old branches and maintain the ideal posture after flowering in spring, renew the branches with heavy pruning, and maintain the tree shape with light pruning. Species that bloom in the new shoots of the current year can be pruned in winter or early spring. For ornamental branches and foliage species, heavy pruning should be carried out in winter and early spring, and light pruning should be carried out afterwards to allow most branches and leaves to germinate.

Species with strong germination power or those that tend to dry out in winter can be stripped from the ground in winter to re-sprout in spring.

3. Cold-proof: Some garden plants are difficult to adapt to the severe cold in winter, or suffer from late frost after tree germination in early spring, so that the plants wither, in order to prevent frost damage, the following measures are often taken:

1) Strengthen cultivation management and enhance the cold resistance of trees.

2) Irrigation of frozen water and spring irrigation.

3) Protect the root neck and root system auspicious air, after irrigating winter water, it is very effective to pile soil at the root neck to prevent cold, generally 40-50 cm high, and pile solid.

4) Protect the trunk:

Before winter, wrap the trunk of a cold-tolerant tree with straw or straw rope to a height of rice or to the branches.

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.Water the flowers with warm water.

The weather in winter is relatively cold, although it is said that it is necessary to reduce the digging and watering of potatoes in winter, but if the indoor temperature is above 20 degrees Celsius, it is also possible to water the flowers. The water used to water the flowers is also very important, 2Keep the potting soil dry.

The temperature in winter is relatively low and slippery, the evaporation of water in the soil will be relatively slow, and after winter, many flowers have less demand for water.

3.Try not to fertilize in winter.

In winter, the weather is cold, and the metabolism of plants is relatively slow, so the plant's demand for fertilizer is not very high, and it is necessary to reduce fertilization in winter. Especially when the temperature is below 20 degrees Celsius.

In the winter maintenance of plants need to rest the following blind brothers: 1, the sun is relatively weak in winter, and plants that like sunlight such as the year bent fruit are placed in a place with weak light, and the leaves will be dull and yellow, such as Junzi orchid, which needs full exposure to sunlight in winter. 2. Many plants like the humidity of the air, such as green baskets, but in winter in the north, there is heating in the home, which will make the air dry, so you should water it frequently to make the soil in the pot have enough humidity.

It is necessary to pay attention to the watering situation, pay attention to the time of sunshine, pay attention to whether to change the pot, whether to turn the soil, and pay attention to the temperature.
