Plum tree grafting time and method are as follows:

Grafting time: About one week before the rootstock germinates in spring, in late March of the Gregorian calendar, plums are grafted by single bud transcision or skin grafting. tree, the survival rate is higher. In addition, the survival rate is also very high when grafting with xylem budding is used in September.

Grafting method: Water the rootstock once the day before grafting. During grafting, use a knife to flatten the cross section of the rootstock, then use a grafting knife or blade to make a split about 3 cm long, and cut the lower end of the scion. Also cut into a wedge-shaped noodle that is slightly thicker on one side and about 3 cm thin on the other side, leaving only 2 to 3 buds.

Finally, sow the slightly thicker side of the scion toward the outside and the thin side toward the inside of the split, aligning the cambium layer, and tie it tightly with a wide plastic strip. Tie the upper cut of the scion with plastic film to prevent water evaporation and insect damage. If you take a dry bath or in windy weather, you must use a transparent plastic bag, put a small cotton ball that absorbs enough water inside, cover the upper part of the self-port and tie the bag tightly.

Benefits of plum tree grafting

1. Improve the plant's ability to withstand low temperatures. Due to the well-developed root system and strong stress resistance of the rootstock, the grafted seedlings are obviously tolerant to low temperatures.

2. It is helpful to overcome the hazards of continuous cropping and can greatly reduce the damage caused by salt accumulation and harmful substances in the soil.

3. The absorption range and ability of the root system are expanded. The root system of the grafted plant is doubled compared with the self-rooted seedlings. It can absorb about 30% more nitrogen and potassium and 80% more phosphorus than the self-rooted seedlings in the same area, and Can utilize phosphorus deep in the soil.

4. It is helpful to increase the yield. The grafted seedlings have thick stems and large leaves, which can increase the yield by more than 40%. Early spring is the best time for grafting plum trees. You must pay attention to the amount of watering when grafting. . After grafting, the joints should be tied tightly and loosened in time after a period of time to ensure their growth. The grafted plum tree will have certain benefits in increasing the yield and taste of the plums.
