How to graft carambola seedlings? Introduction to efficient grafting technology attached!

Carambola is a fruit native to China. In order to improve the disease resistance and yield of carambola, many farmers often use grafting to cultivate plants and increase income, so how to graft carambola seedlings? With the introduction of efficient grafting technology!

First, select rootstocks

If you want to graft a good seedling. There should be a certain standard for the selection of rootstocks, which requires that the rootstock seedlings must be higher than 30cm and the stem thicker than 0.7cm. In addition, when cultivating rootstock seedlings for grafting, we must strengthen management, especially in the aspects of water and fertilizer, loose soil weeding, diseases and insect pests and pruning. After these processes, the rootstock seedlings grow neatly and evenly, and they are first-class rootstock seedlings.

Second, select scion

Like the selection of rootstocks, the scion has its strict selection criteria. The scion is cut from the mother plant with good varieties, strong growth, high and stable yield and strong resistance to diseases and insect pests, and the scion branch is required to be of the same year or one year. Cut about 30-50cm of the 0.5cm branches in the sunny part of the crown, with green leaves and buds on the branches, which is conducive to successful grafting. After cutting, the compound leaves and shoots will be cut off in time. Then cut the long branch into two sections, and then wrap it with a wet towel and place it in a cool place, preferably within 48, otherwise it will lead to grafting failure.

Third, grafting time

When carambola is a tropical and subtropical fruit, it likes a mild climate environment. It grows continuously all the time except between winter and spring, so it can be grafted from late spring to late autumn. According to experiments, in the environment of extremely high temperature in the south, the survival rate of 3-4 grafting is the highest, while in May-October, the survival rate is between 70-80%. Grafting is to avoid sunny weather as far as possible, with rainy and sunny weather in the morning is the best, but in high temperature at noon, the survival rate is very low.

4. Grafting method

There are many grafting methods of carambola, but the most commonly used one is single bud grafting. First prepare the tools used for grafting, then 25cm the rootstock seedlings off the ground and cut off the scion. The specific method is that the base of the scion is facing outward, close to the index finger of the left hand, about 1-2cm under the bud is cut into a 40-50 degree slope, then the epidermis on the back of the cutting surface is removed, and then the scion is cut in a sprout dish filled with fresh water. After that, the rootstock will be cut out smoothly, cut down vertically with a knife, and cut into a 40-50 degree cut like the scion, then closely connect the scion with the incision, and then wrap it with plastic film, so that it will be grafted, and it should be checked in time after grafting, and the grafting failure should be repaired in time, and the film should be punctured in time when the grafting begins to sprout successfully. Let the buds stick out and grow.
