How to graft the yellow peel tree to improve the survival rate (when is the best time to graft the yellow peel fruit)

1. Grafting time

The grafting time of yellow fruit is generally selected from March to October. Among them, the survival rate is the highest in April and September, which can reach more than 95%.

The climate at this time is warm and suitable, with very few sudden changes in temperature, which is very suitable for the healing of grafting wounds and greatly improves the survival rate.

2. Optimization of rootstock and scion

Grafting is the complementary advantages of rootstock and scion. Therefore, in addition to ensuring the affinity between the two, attention should also be paid to the optimization of rootstock and scion.

The rootstock should be selected from mature and healthy new shoots, which should not be too thick or too thin.

The scion should be selected from branches that are in the peak fruit-bearing period and are in the middle and upper part of the crown. The branches should be sunny and strong, and there should be full buds on them. When grafting, keep 2 to 3 buds on each section.

3. Grafting Technology

Grafting is a delicate technical job, and the cutting, grafting and wrapping should be done "fast, accurate and steady" during the process.

Fast means that the cutting is done with skill and cleanliness, and the joint surface is made smooth and perfect, so that the rootstock and scion can fit perfectly, blend with each other, and facilitate survival.

Accurate means that during grafting, the rootstock and scion should be matched and fit together as accurately as possible.

Stable means striving to make the wrapping delicate, firm and secure.

4. Management after grafting

Management after grafting is the key to ensure survival rate. The following points should be noted.

1. Ensure the growth environment is warm and moist to ensure the appropriate temperature, water and nutrition supply for the rootstock and scion.

2. Pay attention to shade and sun protection, and avoid heavy rain to prevent the scion from withering and the wound from being soaked.

3. Pay attention to sterilization and insect prevention to prevent wound infection and insect pests from gnawing at buds. Spray sterilization and insect prevention diluted liquid around and in the soil appropriately.

4. Pay attention to check the survival status and re-graft those that have not survived in time.

5. Wipe off the bud tips on the rootstock in time to avoid unnecessary nutrient consumption.

In short, although the grafting of yellow fruit seems easy, it requires carefulness, patience and meticulous work. From the preparation of rootstock and scion to the management after grafting, it is a critical period to ensure its survival. It is advisable to meet its suitable living conditions as much as possible to facilitate its survival .
