It is now possible to graft peach trees, but the grafting effect and survival rate will be affected by various factors, especially the choice of grafting time. The following is a detailed analysis of peach tree grafting time: 1. Optimal grafting time
1. Spring: Spring is one of the main periods for peach tree grafting, during which the temperature gradually rises and the moisture content of the rootstock increases. Grafting is easy to heal and has a high survival rate. Generally speaking, spring grafting can be carried out before germination, around early March.
2. Autumn: Autumn is also a suitable period for peach tree grafting, especially after the leaves fall in autumn, when the tree enters a dormant state. Grafting at this time is also beneficial for wound healing and has a higher survival rate. 2、 Grafting methods in different seasons
1. Spring: Mainly using branch joining method, such as cutting and joining. Before grafting, the upper branch of the rootstock needs to be cut off, and a longitudinal cut should be made at an appropriate position. Then, the scion should be wedge-shaped and inserted, with the formation layer aligned with one side, and wrapped with plastic strips.
2. Summer and autumn: mainly using bud grafting method. When grafting, it is necessary to peel around the top and bottom of the rootstock by 1 centimeter, reaching deep into the xylem, and then make a longitudinal cut to gently peel off the cut skin together. Next, peel off the bud wrap from the scion using the same method, gently align it in the original direction and press it tightly against the rootstock to ensure that the interface matches. Immediately wrap it securely with a plastic tie. 3、 Precautions
1. Climate conditions: The specific grafting time needs to be determined according to the local climate conditions. For example, in warm and humid areas, the grafting time in spring can be slightly earlier; In cold and dry regions, it needs to be postponed appropriately.
2. Grafting technique: During grafting, attention should be paid to operational skills, such as maintaining smoothness and aligning the formation layer when cutting the scion, in order to improve the survival rate of grafting.
3. Post management: After grafting, post management is also necessary, such as timely removal of sprouts, unbinding of plastic strips, pest control, etc., to ensure the healthy growth of grafted seedlings.
Although peach trees can be grafted now, in order to improve the survival rate and effectiveness of grafting, it is recommended to choose a suitable grafting time and method, and pay attention to operational skills and post grafting management.
