How to brake Qiu Shu?

1, bark scraping. As the saying goes, people live with a face and a skin. Without bark, trees will die quickly, because bark is an important way to transport nutrients. Without bark, the nutrients under the soil can't be supplied to the branches, and it won't be long before the trees will die. Bark can be scraped around the trunk, and the width is about 10 cm-20 cm. I have seen a family's peach trees grow too big before, and one of them was a little in the way, so I cut a circle of bark on the branch that was in the way. In two or three days, the leaves on this branch will begin to wither, and it will not affect the growth of other branches. So scraping bark to kill trees is both environmentally friendly and useful.

2. Cut the grass and get rid of the roots. Roots are mainly used to absorb nutrients and water in the soil. If the roots die, the tree will certainly not live long. We will be very careful when transplanting trees, which is actually the reason. There are many ways to kill roots, such as using high-concentration salt water, using waste engine oil, adding water with quicklime and using herbicides. I think it's best to kill the roots with high concentration salt water, because this will not worry about affecting the soil environment, but also effectively kill the roots. The use of waste engine oil or herbicides will cause more or less pollution to the soil.

3. Change the composition of the soil so that the roots can't absorb water and nutrients normally, and the trees will soon die. For example, dig a pit around the root of a tree, and put a lot of high-concentration salt water or fertilizer in the pit, so that the root can't stand this ingredient, which leads to the rapid death of the root, so that the tree will die quickly.

4. Injecting trees with drugs that destroy tree cells with syringes can also make trees die quickly.

Water the tree with plenty of water, and let the tree soak in the water every day, so that the tree will die quickly because of too much water.
