Basic protective measures for tree maintenance in winter

First, timely irrigation of frozen water.

The whole life process of garden trees is inseparable from water. Although the evaporation in winter is small and the water demand is relatively small, it affects the cold resistance of garden trees and their growth and development in the coming year. Therefore, trees, especially newly planted trees, should be watered at 1 1. That is, "irrigation with frozen water". After irrigation, a mound is cultivated at the base of the tree by combining with frozen water. This not only supplies the water needed by the tree itself, but also improves the cold resistance of the tree.

Second, fertilization.

After the treetops stopped growing in autumn, the root system showed another growth peak. Therefore, according to the age of the tree and the length of planting time, some organic fertilizer or chemical fertilizer should be applied appropriately in late autumn and early winter, and shrubs should be planted appropriately to make the fertilizer permeate, so as to promote the generation of new roots, enhance the tree vigor and lay a good foundation for the growth and development in the coming year.

Third, shaping and pruning

According to the different application purposes of garden trees, correct pruning can not only adjust the tree shape, but also coordinate the relationship between the above-ground and underground parts, promote flowering and fruiting, and eliminate pests and diseases. This work can be completed around the "winter solstice". If the quantity is large, it can be extended to around the Spring Festival. According to the growth characteristics of trees, the dead branches, weak branches, pests and diseases branches are cut off together, and the overgrown branches are properly retracted to improve the ventilation and light transmission conditions inside the crown and cultivate an ideal tree shape. For larger wounds, drugs and lead oil should be used for disinfection to protect the wounds.

Fourth, the trunk is painted white.

Whitening the trunk in winter can not only reduce the harm caused by the large temperature difference between day and night, but also eliminate the pests and diseases that overwinter in the cracks of bark.

Verb (abbreviation for verb) cut down dead trees

Due to various reasons, such as aging of trees, invasion of pests and diseases, man-made destruction, etc. Some trees died, which destroyed the whole landscape and affected the city appearance. You can use your spare time to cut down those irretrievable trees as soon as possible and replant seedlings of the same specifications.

Six, clean up weeds and fallen leaves

The defoliation of weeds is not only a wintering place for some diseases and insect pests, but also prone to fire in dry and windy winter. Therefore, the fallen leaves of weeds in the green space should be cleaned up and treated centrally, which not only eliminates the source of pests and diseases, but also eliminates the hidden danger of fire.

What are the benefits of afforestation?

1. Afforestation can conserve water and soil. In places with low vegetation coverage, a large amount of sediment will flow into rivers in rainy season, destroying fields, filling riverbeds and silting estuaries, which is extremely harmful. To curb soil erosion, we must plant trees, because the roots of trees are as big as crowns and can hold the soil as firmly as giant hands. The water in the captured soil is continuously absorbed and stored by the roots. According to statistics, an acre of forest stores 20 tons more water than no forest area.

Second, afforestation can prevent wind and fix sand. Wherever the sandstorm blows, the countryside is buried and the city becomes ruins. In order to resist the attack of sandstorm, it is necessary to build shelterbelts to weaken the wind. Once the wind meets the shelter forest, the speed will be reduced by 70% ~80%. If many forest belts are arranged in parallel at a certain distance and grass is planted, the sand blown by wind energy will be reduced.

Third, afforestation can provide many useful things for human beings. Many fruits and medicinal materials are forest products; Tea, rubber and new carbon come from trees. Forests are really useful.

Fourth, afforestation can completely eliminate pollution. According to statistics, an acre of forest can absorb 20,000-60,000 kilograms of dust a year, absorb 67 kilograms of carbon dioxide and release 48 kilograms of oxygen every day. It can absorb 4 kilograms of toxic gas sulfur dioxide in a month, and one acre of pine and cypress can secrete 2 kilograms of bactericide for two days and nights, which can kill bacteria such as tuberculosis, typhoid fever, diphtheria and dysentery.

Fifth, it can reduce noise, beautify the environment, maintain ecological balance, and provide an ideal place for human beings to study, work, entertain and live.

When is Arbor Day?

March 12 is Arbor Day in China. Arbor Day is to protect and encourage people to plant trees, encourage people to care for trees and remind people to pay attention to trees. Trees play a very important role in human survival and the ecological environment of the earth. 1928 is designated as March 12 to commemorate the death of Sun Yat-sen. At the 6th meeting of the 5th NPC Standing Committee, March 12 was decided as the National Arbor Day.

The origin of Arbor Day

In ancient China, Tomb-Sweeping Day had the tradition of planting trees by inserting willows, while the modern Arbor Day was first initiated by Nebraska in the United States.

19th century ago, Nebraska was a bare wasteland, with few trees, dry land, strong winds and yellow sand all over the sky, and people suffered greatly. 1872, Julius Sterling Moreton, a famous American agronomist, proposed to stipulate Arbor Day in Nebraska to mobilize people to plant trees in a planned way. At that time, the state agricultural bureau adopted this proposal through a resolution, and the governor personally stipulated that the third Wednesday of April would be Arbor Day every year. After making this decision, millions of trees were planted that year. In the following 16 years, 600 million trees were planted one after another, eventually turning the 654.38+10,000 hectares of wilderness in Nebraska into dense forests. In recognition of Moreton's achievements, 1885, the state legislature officially designated April 22nd, Mr. Moreton's birthday, as the annual Arbor Day, with one day off.

In the United States, Arbor Day is a national holiday, and there is no unified national date. But every April and May, every state in the United States organizes Arbor Day activities. For example, Rhode Island stipulates that the second Friday in May is Arbor Day, which is a day off. Other states have fixed dates, and some temporarily decide the date of Arbor Day by the governor or other state government departments every year. Whenever Arbor Day comes, people from all walks of life, mainly students, form a mighty army of tree planting and devote themselves to tree planting activities.
