How is the rose grafted?
How is the rose grafted? Please give guidance for rose grafting can refer to the following methods: first, the cultivation of rootstocks. The variety of rootstock can be selected, such as flag vine, pink rose and so on. To use more than 2-year-old large rootstocks, the growth is exuberant, the root system is developed, and there are no diseases and insect pests. After flat stubble before winter, several sturdy branches sprout in the following year, which can be used as grafting. Second, grafting and management. Grafting method: (1) choose an erect branch with exuberant growth among the tufted branches. From June to August, the "T" shape bud grafting was used at 1 meter above the ground. Do not cut the anvil after survival, wait for the fallen leaves to cut the anvil. Cut off all ungrafted branches and protect the grafted branches against cold, preferably wrapped in straw or plastic (11230,-55.00,-0.49%) cloth or covered with plastic pockets. Cut the top the following year and cut off the rootstocks above the buds to promote the germination and growth of the buds. At the same time, all the germinated buds of the rootstocks were erased. And place an upright stick close to the rootstock to prevent it from being blown down by the wind. After budding and growing to the first flower, the bud is removed to promote secondary branches. When the secondary branches grow to a certain length and differentiate the buds, they should also be removed to promote re-branching on the secondary branches. After a period of branching and growth, it can form an umbrella-shaped or crown-shaped tree. At the same time, the trunk also thickens and grows. (2) after the above rootstocks were cultured, the rose varieties with strong growth and good erect were selected as scions, the buds were grafted on the base of strong rootstocks in autumn, and the top was cut in the spring of the following year to promote the upright growth of buds. At the same time, cut off the sprouting buds of the rootstock, and when the erect branch grew to more than 1.5 meters, the second grafting was carried out at a height of 1 meter. After survival, buds are picked and pruned according to the above methods to promote branching. That is, to form a good crown. Third, the selection of rose varieties. To make tree-shaped rose, it is best to choose varieties with weaker branches as scions, such as multi-flowered rose, compound rose and so on. Stretch and relax the branches and droop appropriately to form an umbrella-shaped, globular or weeping willow-shaped crown. In addition, several varieties can be grafted. When the rootstock is cultured, the trunk is first formed and cut at 1 meter to make it branched. Then budding is carried out on the branches. Different varieties are grafted on different branches and grow up to make a rose blossom with colorful flowers. However, it should be noted that some varieties grow strongly and some varieties grow weakly. It is best to graft the varieties with the same growth potential on the same tree in order to prune and control the flowers, so that the flowers bloom better and the flowering period is longer.
