Apricot tree grafting is a technical activity, especially from June to September, because this is the growth period of apricot trees and the period when the survival rate of grafting is the highest. This article will detail the key techniques and steps for apricot tree grafting during this time.
1. Choose the right grafting time.
June to September is the active growth period of apricot trees, and the sap flow is relatively vigorous, so this time is the best time for grafting. However, it should be noted that it is best to avoid extreme heat or rainy seasons and choose a time when the weather is more stable for grafting.
2. Choose the appropriate grafting method.
According to the characteristics of the apricot tree and the purpose of grafting, different grafting methods can be selected, such as bud grafting, branch grafting, etc. Among them, bud grafting is the most commonly used method, which is suitable for various apricot tree varieties and has a high survival rate.
3. Prepare grafting tools and materials.
Before grafting, you need to prepare the corresponding tools and materials, such as sharp grafting knives, scissors, plastic film, labels, etc. Make sure these tools and materials are clean and sharp to reduce damage to the apricot tree.
4. Choose healthy scion and rootstocks.
Scion is a key part of grafting, and healthy, pest-free, and robust apricot branches need to be selected as scion. At the same time, it is also necessary to choose healthy apricot trees or peach trees with strong scion affinity as rootstocks.
5. Carry out grafting operations.
On the basis of the prepared tools and materials, the grafting operation begins. First, the scion and rootstock are each cut into the right shape, making sure that their cuts are smooth and the size matches. Then, insert the scion into the incision of the rootstock, making sure that they are tightly combined. Finally, the grafted site is wrapped in plastic film to maintain humidity and prevent the invasion of pests and diseases.
6. Strengthen post-grafting management.
After grafting, the apricot trees need to be carefully managed. Regularly inspect the condition of the graft site, and if the plastic film is found to be loose or detached, it needs to be rewrapped. At the same time, pay attention to the prevention and control of pests and diseases to ensure the healthy growth of apricot trees. After the grafted site has healed, the plastic film can be gradually removed to allow the apricot tree to grow naturally.
7. Observe and record growth.
After grafting, it is necessary to observe and record the growth of the apricot tree regularly. If an abnormality or grafting failure is found, timely measures need to be taken to remediate or re-graft. At the same time, the effect and survival rate of grafting can also be evaluated by recording the growth.
Through the operation and management of the above seven steps, the survival rate and effect of apricot tree grafting from June to September can be effectively improved. However, it should be noted that grafting techniques require certain experience and skills, and beginners can practice and learn Xi under the guidance of professionals. Through continuous practice and learning Xi, we can gradually master the key techniques and key points of apricot tree grafting, and provide strong support for the production and management of orchards.
