Grafting time
Grafting can be carried out in all seasons except the low temperature period in winter. Because winter and spring are cold and humid for a long time, the wound is not only difficult to heal, but also expands, endangering the plant. Therefore, the best grafting time is March-June, 65438+1October, which has sufficient healing growth period and is conducive to the next year's results.
Knives for grafting should be disinfected with alcohol or white wine to prevent bacterial infection. Conditional availability. Dipping the base of scion with sodium naphthylacetate solution can not only promote the formation of callus, but also improve the survival rate. ?
Connect the cut scion to the other end with thorns, and connect the scion with the rootstock with thorns. Rootstock and scion should be as close as possible without gaps, so as to avoid poor healing caused by bacterial infection. Then, each side is fixed with a thorn, and then a thin thread is tightly wound around the base.
