Grafting technique of Mango

As the planting area of mango in China is increasing year by year, some fruit growers usually use grafting technology in order to cultivate excellent and high-yielding plants. grafting technology has become one of the necessary management techniques for fruit farmers. So when should mangoes be grafted? How do you do it? Let's have a look with the editor.

1. Grafting time

The suitable time for mango grafting is above 20 degrees. Once the temperature is lower than 20 degrees, the survival rate of grafting will decrease with the continuous decrease of temperature. Therefore, it is best to be grafted from March to April, or from August to October. If the temperature is dry, irrigation should be given for 1-2 days before grafting to improve the survival rate of grafting. It is not suitable for grafting in high temperature and rainy weather.

2. Preparation before grafting

The scion is collected from the excellent mother plant, the mother plant requires pure, high yield, stable yield and no diseases and insect pests, and the scion should choose 1-2-year-old branches with sunny outside the crown of the mother plant, strong growth, full bud and free of diseases and insect pests. The spring and summer shoots of last year or the spring shoots of that year are generally used in spring and summer, while the spring shoots of the same year are generally used in autumn, and the branches that are blooming and fruiting or just picking fruit should not be used as scions. The scion was defoliated in the first half of the grafting, soaked in carbendazim solution for 3-5 minutes after the petiole fell off, and prepared for inoculation after drying. It is best to understand the inoculation after the scion is cut off, no more than 30 days at the latest, so as not to affect the survival rate.

3. Budding method

Select rootstock diameter above 0.8cm, sprout interface at rootstock 30cm off the ground, cut two parallel incisions from top to bottom with knife, wide 1cm left and right long 3cm, cut the upper end of the incision into a shed shape, tear the bark down, remove most of the cortex, leaving only a small segment. Select the full buds growing on the scion, take the buds as neutral, carve a square with a length of 3cm and a width of 0.5-0.7cm, and reach the xylem in depth. Take out the buds, peel the xylem and cut it into the shape of the tooth interface. The peeled buds are placed in the center of the interface, the lower end is inserted into the abdominal capsule, and there is a little gap between the upper end and both sides and the incision of the rootstock. After compression, it was wrapped with plastic film. After 20-30 days of the month, the interface healed, and the wrapped film was released when the buds were expanded and protruded.

4. Splicing method

Select the rootstock with a diameter above 0.5cm, cut the rootstock obliquely at 30 cm off the ground, peel the high side down a straight 2cm-long incision, deep to the xylem, and then cut off more than half of the cortex. Cut the base of the scion into a bevel, and then cut everything down on the tip side, the length is the same as the rootstock, also cut off most of the cortex. Insert the scion into the cut of the rootstock to make the cortex match and tie it tightly with a thin film seal.
