When should persimmon trees be grafted?

There are two grafting methods for persimmon trees: branch grafting and bud grafting. Grafting is best carried out when the sap of the rootstock is flowing, just budding and the scion just budding, which requires the scion to be preserved at a relatively low temperature. The grafting time of persimmon trees is generally in spring. In early March, branches began to germinate in spring, with rich nutrition and high air humidity, and the grafting survival rate was the highest. When and how to graft persimmon trees, we should choose a healthy wormless hole for more than 2 years.

This method is also to cut off the rhizome at a proper position, then flatten the section and cut it vertically in a smooth place for about 2-3cm. At this time, the scion is cut into horse ears, leaving 2-3 buds, and the phloem is slightly removed from the back of the section. The time for grafting persimmon trees by gently inserting scions between xylem and phloem of rootstocks is generally in spring, and the specific time is early March. In spring, branches began to sprout, with rich nutrition and high air humidity, and the grafting survival rate was the highest; It can also be carried out in summer, and it is most suitable before and after the Xiaoman solar term, and the northern region can be grafted in advance in summer.

If the time is too early and the temperature is cold, it is not good for growth. If the time is too late, the growth period just meets the hot summer period, and the survival rate drops. Besides spring, summer and autumn can also be chosen. Select scion branches without spreading leaves and buds. Cut the newly picked shoots into inverted triangles with symmetrical sides with a sharp blade, then cut a hole in the middle of the rootstock and insert it. It must matter, there should not be too much space, and the grafting position is about 15 cm from the ground.

Persimmon is grafted with soft jujube as rootstock, which has the characteristics of drought resistance, waterlogging resistance, disease resistance and insect resistance, and is an ideal material for persimmon grafting. Grafting period. Grafting can be carried out from early September to early October of 10, or from late March to mid-April of the following year. Generally, avoid grafting or open grafting before and after Tomb-Sweeping Day or in Xiaoyangchun, and the best grafting is 30-50 cm, and the joint is 2-3 cm with spores.
