Grafting time and scion selection
In the spring, summer and autumn, the grafting and grafting were performed in low grades. Before spring shoots sprouted in the summer and autumn, the shoots used in the shoots were aged and matured. Due to the fact that the age of the tree being replaced and the anvil are relatively large, the scion diameter must be between 0.5 cm and 1 cm, otherwise it will affect the survival.
Grafting method
First saw the anvil pile which was changed to be sawed off at a distance of 20cm to 30cm from the ground. Cut the anvil with a sharp grafting knife and cut the 3cm long interface from the top to the bottom of the cutting plane. Deeply reach the xylem and view the anvil. The size of the pile is determined by the number of tree heads to be connected, and the anvil with a diameter of 3 cm to 5 cm must be grafted with 3 branches. Note that the distribution should be uniform. The scion used is 5 cm long, with 5 or more shoots retained, cutting the lower part of the scion from the 1 cm to the back, cutting the epidermis 2.5 cm back and deep into the xylem, then inserting the scion pods into the anvil. Align the formation layer. After fixing the scion, the right hand used a 4 cm wide grafted plastic film strip to wind from bottom to top, wrapped the anvil pile, and then wrapped the scion.
Post-grafting management
After the grafting, the pesticide was sprayed to prevent the ants from biting through the agricultural film. In each anvil pile, the manure was sprayed with 10 to 15 kg of manure, and then the soil was sowed in combination with loose soil every 15 days. About 10 days after grafting, a large number of "wild shoots" will be extracted at the base of the root of the anvil, which should be promptly removed. In the scion budding stage and leaf spreading stage, each insecticide, acaricide, and disease prevention agent was mixed and sprayed for 2 to 3 times. Each batch of shoots should be topped when they are 10 cm to 15 cm long, which promotes more branches after being cooked.
