With the increasing variety of fruit trees, the variety of varieties that fruit farmers choose to grow is more and more extensive, but some old orchards are mostly previously grown varieties. If we completely cut down, it will cause huge economic losses, and at this time, if high replacement is adopted, This technology not only eliminates some of the losses, but also enables faster gains.
When I read the news, I saw that the fruit growers had a high-replacement of the apple trees, and the trunks died dry. At the same time, the roots also showed different degrees of decay. In response to this situation, Xiaobian will tell you what problems we should pay attention to when we exchange high-quality fruit trees to prevent the phenomenon of death.
Tree age problem
Fruit trees used for high-replacement are best not to choose large trees that are more than 10 years old and have a ground diameter of more than 20cm. Choosing these trees will bring a lot of inconvenience to our later management, which will easily cause management to be in place and increase the rate of dead trees.
2. Grafting method should be appropriate
For high-replacement, you should choose the correct grafting method to carry out the operation in detail. Generally used for the selection of strong buds and scions, the noodles should be as long as possible, light and flat, the nodes should be as much as possible, and the scions should be long, which not only helps the wound to heal, but also facilitates the rapid growth of the branches. It can reduce the death of roots in plants.
3. Strengthen cultivation management
After the high-replacement, it is necessary to strengthen the management of soil and fertilizer, this small series also mentioned in the previous article, if you do not understand the problem can refer to the previous article. For the fruit trees after high-replacement, pay special attention to the operation of underground top dressing and foliar spray fertilizer, and watering at the same time. Of course, the management of the later stage must also keep up, such as smear, pest control and so on.
4. Ring stripping
The reason why this is proposed separately is not put into cultivation management, because this must be taboo. Do not perform peeling and ring cutting measures on the high-quality tree.
The above are some of the problems that the fruit trees have to pay attention to, and more knowledge about fruit trees and agriculture. Please pay attention to the Hui Nong School!
