How do you treat tree roots without moving the soil?

You can spray cyclazinone to let the roots gradually absorb, the roots are surrounded by soil, and the roots can be irrigated after the cyclazinone is mixed with water. However, this root absorption method requires a process, and it takes about two months for ordinary trees and about half a year for larger trees to be completely killed.

It takes a lot of manpower and material resources to break the soil and kill the trees, and it is even more difficult to carry out the work in the mountainous areas with hard geology, so it is necessary to kill the trees without moving the soil. For example, the commonly used soil method in rural areas is to inject the trunk, taproot or circumferentially cut the trunk with diesel and lime water, and then apply and inject it, which requires multiple treatments to be effective.

Use a large amount of quicklime to bury next to the roots of the tree, then cover with a thin layer of soil, and then sprinkle water on the soil. When water and quicklime come into contact, a chemical reaction occurs, producing a large amount of heat. The temperature of the roots of the tree is too high and the water is lost and it dies.

It is also possible to make a fire at the root of a tree. Burn a fire every day, a month later. The roots of the tree die, this method is troublesome and costly, and it is not recommended.

With special weeding or tree killing chemical reagents, such as planting oak trees in the garden, in order to prevent the spread of root diseases, it is necessary to kill oak roots, generally using the 2,4-butyl ester injection method, when using, 2,4-butyl ester is dissolved in diesel fuel and injected into the trunk or coated on the xylem of the trunk, but do not hurt the cambium layer during circumcision, so as not to affect the transmission of the agent to the roots.

There are generally more trees in rural areas, and sometimes the roots of the trees behind the houses are cut down and left under the foundation of the houses, which is a headache for many farmers. When I was building a house in my family, I was very worried about this problem, because I was afraid that tree roots would grow under the foundation, and we had a way to make the roots lose nutrients and rot. We can make a few openings in the stump and plant mushrooms such as fungus, shiitake mushrooms, shiitake mushrooms, etc.

Mushrooms grow by controlling moisture and light. In this way, when the mushroom grows, the original stump will rot. This method.

It takes a bit long, but you can kill two birds with one stone, and you can also get some mushrooms as a reward.

We all dig holes and let the roots absorb toxic substances, which is probably what it means, we all know that plants need water to grow. When the salinity or temperature of the soil is too high, water seeps out of the plant cells. So, we can bury some industrial salt next to the roots, so that the roots lose water and die because the soil is too salty.

This method is not very good for trees with large stumps and well-developed underground root systems. However, this method is very low-cost, and we will use this method.

The simplest and most environmentally friendly method is to block the environment required for the growth of trees, everything grows by the sun, without light and a certain temperature and humidity, it is difficult for plants and trees to thrive, the roots of the tree are covered with black film, and the roots are pressed with bricks or stones to block the growth space of the trees, and it will not take long for the roots to die naturally, which is safe, effective and environmentally friendly.

With pesticides, such as herbicides, with needles driven into the roots of the stump. With a strong fertilizer, make a hole in the stump and fill it. Watering with engine oil, using sulfate hydrochloric acid, etc., can kill tree roots.

However, these methods are not recommended because they are either unsafe or polluting to the soil.

1. The soil at the roots can be dug up to fully expose the remaining roots to the air. You can pile up rotten leaves, trees, and branches, that is, those that have turned brown in color, and crumble at the touch of them, and spray them with water, and cover them with plastic sheets.

2. Sulfuric acid solution can be poured directly. You can use the mother liquor of the tree protector to irrigate the roots, prevent and control airborne diseases, disinfect the plants, gently scratch the trunk with a blade on the diseased skin, and apply the mother liquor of the tree protector with a brush, which can dry up and fall off the diseased skin.

I don't understand why you ask this, but I hope you don't do things that harm the interests of others, and you can water the roots with hot water. It is better to use alkaline water. Pour it for a few days in a row!

There are many ways to make a tree on the ground die. If you don't want to break the ground and let its roots die, you can peel the bark off its trunk so that the tree will slowly dry up and die.

Constantly watering the tree can also make its roots bad, the roots of the tree can't withstand water, if the water is blistered, it will really go bad because of this dampness, just soak it.

The tree in the field can put some other items that will dry up the roots, and then he can also make the roots wither and die without moving the soil.

It is best to transplant large trees during the dormant period of the tree, which is generally the best period before germination in spring and after leaf fall in autumn. Spring is the best time to transplant in the north.

2. Big tree treatment.

The main contents of large tree treatment include: root cutting treatment, crown cutting treatment and early seedling hoarding according to the difficulty of transplanting and surviving tree species. The purpose of pruning is obvious, mainly to maintain the balance of water metabolism in both the underground and aboveground parts of the tree.

The larger the crown, the more bare the roots, the more injured the roots, the more difficult it is to root, and the more the season is reversed, the more the pruning intensity should be increased to reduce the transpiration area of the canopy as much as possible.

3. Digging trees and packing.

Excavation and installation method: At present, the manual excavation soft wood packaging and transplanting method is widely used in China, which is suitable for excavating round soil balls and evergreen trees with a DBH of 10 15cm.

Packing method: Packed with a bag, grass flakes or plastic woven material with straw rope (the trunk is wound with soaked straw rope to the branch point). There is also a wooden box packaging transplanting method, which is suitable for excavating square soil platforms and evergreen trees with a DBH of 15 to 25cm.

4. Hoisting and transportation.

Tree lifting is one of the important links of tree transplanting, which is directly related to the survival of trees, construction quality and the perfection of tree shape. Generally, large trees are transplanted by cranes and trucks.

5. Tree planting.

Before transplanting large trees, the cave soil should be sterilized and insecticidal, that is, 50% Budweiser granules should be mixed with soil in proportion to kill insects, and 50% tobuzin or 50% carbendazim powder should be mixed with soil in the same proportion to sterilize. When conditions permit, some nutrient soil should also be prepared in advance, the specific method is: according to the weight ratio of 50% of sawdust, 30% of plant ash, 20% of cooked soil, fully mixed and placed for 2 3d, to promote its high temperature fermentation, but also to add an appropriate amount of chemical fertilizer as needed.

When transplanting, first lay a layer of nutrient soil at the bottom of the hole, then remove the bandaging on the soil ball, slowly move the tree into the hole with the help of a crane, and pay attention to the direction when righting. When filling the soil to be layered backfill, solid (around the soil ball and the surface should also be paved with nutrient soil), when the backfill to the height of the soil ball 2 3, pour the first water, so that the backfill fully absorbs water, and then add full soil after the water seeps (note that at this time do not be solid), and finally build a cofferdam on the periphery, pour the second water, water enough to water thoroughly. After watering, pay attention to observe whether the soil around the trunk is sinking or cracking, and if so, add soil in time to fill it.

6. Maintenance management after transplanting.

After transplanting large trees, it is necessary to strengthen the maintenance and management in the later stage. As the saying goes: "Three points of species, seven points of management", the truth covers.

For this. From the perspective of the main causes of tree mortality provided by various places, one of the most important is improper management in the later stage, especially in the first year. Therefore, the careful maintenance of large trees after transplanting should be regarded as an indispensable and important part of ensuring the survival of transplanting and the healthy growth of forest trees, and should not be underestimated.
