In recent years, with the increase in the demand for large size sea otters by greening projects, the large and medium sized sea otters in green nursery gardens are obviously not enough, such as the large amount of West Lake jellyfish and colorful leaf species of the royal family such as the sea otters. The same apple tree belonging to the same family as the Haishu was used as the rootstock for grafting the jellyfish. In the orchard, after the fruit-producing period of the apple, although the fruit-producing ability is already weak, its tall tree shape and stout branches can play a role in landscaping. The choice of raw materials Apple tree life is not too long, generally Joe anvil can reach 40 years, dwarfing anvil in 20 years. When choosing an apple tree, you must purchase a middle-aged and old tree that is about 10 years old. The maximum age cannot exceed 15 years. In addition, do not choose a serious apple tree. Different varieties of apple trees have different affinities for sea otters. The common apple tree varieties include the Red Star series and the Fuji series. These two kinds have a wide range of affinity, and it is better to use an anvil. Before grafting, it is necessary to test the affinity between apple and jellyfish. Since the affinity of each variety is different, try to use good affinity grafting. In the year before grafting, apple trees need to be rooted to promote the germination of their new roots. At the same time, cut a nutrient groove with a width of 70 cm and a depth of 30 cm around the root and apply it to a mixture of fermented organic fertilizer, ternary compound fertilizer and fertile soil. Grafting operations One year before the apple is grafted with sea bream, a large crown needs to be shrunk to leave a large skeleton, which will be carried out after the annual branch is issued. Grafting is divided into two types: spring connection and summer connection. The spring connection is mainly used to connect the skin and then connect the skin. The summer connection adopts the T-shaped bud or the xylem bud. Before the spring connection, the ditch was opened under the apple canopy, and nitrogen, phosphorus and potassium fertilizers were applied to ensure its vigorous growth. After the grafting, nitrogen fertilizer such as urea could be added. In the summer when the apple tree is growing, it does not need top dressing. After grafting, water according to the dry and wet conditions of the soil. Be careful not to collect too much water. Summer grafts are numerous and large, and it is best to set up support. At the same time, observe carefully and promptly remove the buds that apple germinated.
