Sweet cherry summer budding technique
The sweet cherry bud graft has the advantages of longer grafting suitable period, easy access to the scion, simple technical operation, easy remediation after graft failure, and the like, and is a grafting method carried out during the growth period. The buds will be suitable for the first time in June (before the arrival of the rainy season), and the second is in late July to late August (before the rainy season ends until the formation stops growing). In the rainy season (early July) budding, the interface is easy to flow, the wound healing is difficult, and the survival rate is very low.
T-shaped bud connection. Take shoots that are full of growth, remove the leaves and then use a grafting knife 2.5 cm below the bud to cut 1/3 of the xylem laterally, then straighten out to the top of the bud, 1 cm above, and then above the bud. Cut a knife at a centimeter and reach deep into the xylem to remove the roughly rectangular bud. At the same time as the buds are cut, at the point of 5 to 10 centimeters from the ground, the smoothing part is cut into a T-shaped interface with a knife, and it is deep to the xylem, and its length is just enough to accommodate buds. The cut buds were inserted into the anvil interface so that the buds closely matched the interface. Then cut all the incisions from top to bottom with plastic sheeting to expose only the axillary buds and petioles.
In order to increase the survival rate of grafting, ginseng root seedlings and other excellent plant regulators can be used to grow as soon as possible after grafting. If the weather continues to dry before budding, the rootstock should be fully irrigated 2 to 3 days in advance in order to make the grafting operation easier. It can also improve the survival rate. However, 15 to 20 days after grafting should not be watered, and if the rainfall during the rain but also do a good job of flood prevention, in order to avoid the phenomenon of plastic flow, reduce the survival rate, after grafting according to the fertilization stage appropriate use of microbial fertilizers such as golden treasure can be fast Grow.
