How to deal with wounds after tree pruning, and how to deal with wounds after pruning

Some experts say that trees themselves produce callus to heal wounds naturally, and that this self-healing ability is stronger than any protective agent. Others, some experts, believe that; The best way to protect the cut is to seal the wound immediately with a protective agent to prevent rainwater from infiltrating and attracting parasitism of germs, and also to prevent air-drying and cracking.

This is because the natural healing process of plant wounds is much slower than that of germs, and some wounds often take several years to heal completely, and during such a long period of time, the wound will rot once it is diseased. There is some truth to both of these arguments, because poor protectants tend to prevent the cambium from producing callus. However, there are always positive and negative aspects to things, so they should be treated on a case-by-case basis.

If winter pruning is carried out in the north, it is better to seal the wound immediately with a protective agent, otherwise under the cold wind, the branches below the wound will be quickly dried by the freeze, and the side buds near the cut will also die at the same time. If pruning is carried out in late spring and early summer, the sap in the tree is very smooth and the metabolism is also vigorous, even if the wound is not sealed with a protective agent, it can heal quickly. In the summer pruning during the hot and humid rainy season, it is necessary to seal the wound with a protective agent in order to prevent the growth of mold.

In addition, after the tree is pruned, the thicker the branches, the larger the wound, and the less likely it is to heal after pruning. The wound heals naturally after pruning and the recovery is quick, so no treatment is usually required. The wound area on the large branch is large, and it does not heal for a long time, which is easy to cause decay and form cavities, and it is also easy to be infected with germs and affect the tree's strength and lifespan.

He is currently the director of the greening office of Huajia Comprehensive Service Office of North China Oilfield Company, the director of the garden plant protection center, and a senior engineer. Mainly engaged in garden plant protection and greening planning and design.

Scrape the wound with a knife and polish it, disinfect it with 2% 5% copper sulfate or mercury aqueous solution, and then apply a protective agent.

The formula of the protective agent is: 1. General protective agent: use 1 part of animal oil, rosin, beeswax, heated, dissolved, and mixed well, and then it can be used.

Fujiao coating: Add 1% wall paint to the boiled 1000 times water glue solution, stir while adding, adjust until it is thin and suitable for smearing, then weigh, and then add 2% fungicide Fumei arsenic, stir evenly to become 106 Fujiao coating.

3. Rosin clear oil mixture: 1 part of rosin and 1 part of clear oil, first heat the clear oil to boiling, and then add the rosin powder to stir.

After pruning the plant, the wound area can be coated with an appropriate amount of plant ash, which can avoid bacterial infection at the wound site and promote the wound healing of the plant. An appropriate amount of carbendazim solution can also be applied to the cut part of the plant, but the solution should be diluted with water. If the plant is grown outdoors, you can apply an appropriate amount of tree healing agent to the wound area of the plant.

Plants grown at home need to be pruned when they grow to a certain period, and proper pruning of plants can save nutrients for plants and promote the growth of new branches and leaves. After pruning the plant, it is necessary to apply an appropriate amount of plant ash to the wound of the plant, which can avoid bacterial infection at the wound site and promote the wound healing of the plant.

After pruning, the wound site can be coated with an appropriate amount of carbendazim solution, which can disinfect and sterilize, which is conducive to plant growth. Before using carbendazim solution, it needs to be diluted with water, otherwise the concentration is too high, which will affect the healing of the wound site of the plant. Applying the diluted carbendazim solution to the wound site of the plant can prevent the plant from being infected with bacteria.

After pruning, the wound area should not touch the water, and if it is a potted plant, the plant can be moved to a cool and ventilated environment for maintenance. If it is an outdoor plant, after pruning the plant, you can apply an appropriate amount of tree healing agent to the wound of the plant, which can avoid the infection of bacteria in the wound of the tree caused by rain or insect pests, which is conducive to the better growth of the plant.

Plants need to be strengthened after pruning, and during the maintenance period, the plants should be given a suitable temperature, sufficient light, water and fertilizer, so that the plants have sufficient water and nutrients for the growth of flowers and branches. If it is a potted plant grown indoors, it can be placed in a ventilated place indoors, and during the maintenance period, the windows should be opened frequently to keep the room ventilated.

After pruning fruit trees, it should be treated in time to avoid a large loss of water, invasion of pests and diseases, for the larger wounds left by fruit tree pruning, you can apply soft mud to paste the paste tightly, and then wrap it with plastic film. You can also apply callus cream to the wound, dip the appropriate amount of callus paste with a brush, and evenly apply it on the wound of the fruit tree, the dosage of callus paste is not fixed, and the specific dosage can be determined according to the size of the wound.

Pruning period: When pruning fruit trees, pruning should be avoided in low temperature periods, otherwise it will lead to frostbite and lead to wound rot, and it is best to prune in a mild climate and suitable season.

1. It is a better way to apply a mixture of paint and turpentine, after the fruit tree wound C comes out, first apply 200 times the liquid 70% thiophanate-methyl on the wound, dry it slightly, and then coat the wound with a mixture of varnish and turpentine. The mixing method of the mixture is 200 grams of turpentine per kilogram of varnish, and it can be stirred evenly. Some paints contain a strong odor that is uncomfortable, and you can choose not to use paint and use another method instead.

2. Apply stone sulfur mixture and petroleum jelly, petroleum jelly is an oil, non-toxic and tasteless, can be used in many aspects, has a closed effect, the wound is smeared with stone sulfur mixture stock solution, slightly dried, and then the petroleum jelly is smeared and covered on the liquid medicine, so that the larger wounds of fruit trees have the effect of preventing cracking, reducing the diseases caused by bacteria and fungal invasion, preventing decay, and preventing the loss of water, all of which have a good effect. Stone sulfur mixture is a kind of fungicide protective agent that everyone is very familiar with, against fungi and fine.

3. Plastic film bundling, using plastic film to tie the wound, can be said to be very common in rural areas, after the plastic film bundling wound, in summer, can avoid being washed by rain, on the wound of the branch, first apply the stone sulfur mixture stock solution, and then tightly wound with the plastic film, with the growth of the tree year, the plastic film can be gradually relaxed, can not be bandaged for a long time.

1: After the tree is thinned, the wound on the tree body, for the large wound with a diameter of more than 2cm, usually the wound is scraped and cut with a knife, and then disinfected with a concentration of 2% 5% copper sulfate solution, these materials are heated and dissolved, mixed well, and then applied to the wound of the tree.

2: If there are long, appropriately placed large branches near the split branches, promote healing to restore a robust tree. It can be fixed and tied with the help of wooden boards, and it can be healed in a short period of time, and it can be untied after half a year to a year.
