How to Graft Mango? Latest Technical Method Tutorial

As the mango planting area in our country increases year by year, some fruit growers usually use grafting techniques to cultivate superior and high-yielding plants. Grafting technique has become one of the essential management skills for fruit growers when planting. So when should mango be grafted? How should it be done? Let's take a look together.

1. Grafting time

The suitable time for grafting mango is when the temperature is above 20 degrees. Once the temperature is below 20 degrees, its grafting survival rate will decrease as the temperature continues to drop. Therefore, grafting in March to April is best, and August to October is also acceptable. If the weather is dry, water should be applied 1-2 days before grafting to improve the grafting survival rate. Grafting is not suitable in high-temperature and rainy weather.

2. Preparation before grafting

Collect scions from superior mother plants. The mother plant should be of pure variety, high-yielding, stable-yielding, and free of pests and diseases. For the scion, choose 1-2 year old branches from the outer sunny side of the mother plant's canopy that are robust in growth, with plump and full buds, and free of pests and diseases. Generally, for spring and summer grafting, use last year's autumn shoots or the current year's spring shoots, while for autumn grafting, generally use the current year's spring shoots. Branches that are flowering, fruiting, or have just finished fruiting are not suitable as scions. Defoliate the scions half a month before grafting. After the petioles fall off, soak them in carbendazim solution for 3-5 minutes. After drying, they are ready for inoculation. After the scions are cut, it is best to understand inoculation; the latest should not exceed 30 days, so as not to affect the survival rate.

3. Bud grafting method

Choose a rootstock with a diameter above 0.8 cm. Open a bud grafting incision 30 cm above the ground on the rootstock. Use a knife from top to bottom to make two parallel cuts, about 1 cm wide and about 3 cm long. Cut the upper end of the incision into a tongue shape, tear the bark downward, and remove most of the cortex, leaving only a small section. Choose a plump bud on the scion, center on the bud, and carve a square piece 3 cm long and 0.5-0.7 cm wide, with the depth reaching the xylem. Take out the bud piece, peel off the xylem, and cut it into the shape of the bud grafting incision. Place the peeled bud in the center of the incision, insert the lower end into the abdominal capsule skin, and leave a small gap at the upper end and both sides with the rootstock incision. After pressing tightly, wrap it well with plastic film. After about 20-30 days, the incision heals. When the grafted bud swells and protrudes, remove the wrapping film.

4. Cut grafting method

Choose a rootstock with a diameter above 0.5 cm. Cut the rootstock diagonally 30 cm above the ground. On the higher side, peel downward a straight cut about 2 cm long, with the depth reaching the xylem, then cut away more than half of the cortex. Cut the base of the scion into a slant, then make a downward cut on one side of the tip, with the same length as the rootstock, also cutting away more than half of the cortex. Insert the scion into the rootstock incision so that the cortices match, then seal and tie tightly with film.
