Rose is a Rosaceae plant, which is suitable for grafting. When selecting grafting rootstock, Rosaceae rootstock should be selected. Common grafting rootstocks of Chinese rose include wild rose, Chinese rose, Rosa davurica, Rosa banki and other plants. Grafting with strong disease-free rootstocks can enhance the disease resistance of plants, reduce the probability of being damaged by pests and diseases, and be beneficial to the growth of plants.
Roses are generally suitable for spring. The mild climate and humid air in spring are beneficial to plant wound healing, plant growth and plant survival rate. Grafting should be carried out before the bud point of rootstock germinates. Choose one-year-old or two-year-old disease-free rose plants and cut off their robust branches with disinfection scissors.
Cut a small mouth obliquely on the cut branch, the incision should not be too long, and it should be controlled between 2 ~ 3 cm. After cutting, soak in water and dry. Plants such as wild roses or vigorous roses are selected as rootstocks, and the rootstocks are crosscut, and the incision should go deep into the woody part of the bark. Stick the cut of the rose branch on the cut of the rootstock and wrap it tightly with a string.
Pay attention to the grafting of Chinese rose. Grafted plants are vulnerable to pests and diseases. When choosing rootstocks, we must choose strong rootstocks without diseases, which can enhance the disease resistance of plants. During the curing period, carbendazim or chlorothalonil should be sprayed appropriately for disinfection and sterilization. Generally, it can be sprayed 1 time within 15 ~ 20 days, which can effectively control pests and diseases.
