(1) After budding, de-sprouting and grafting with pine branches and spring branches, when budding begins in the middle and late April, the plastic bag covering the scion will be broken out, and then the bag will be removed when the new bud grows to 1 ~ 2 cm. It is necessary to wipe off some buds of rootstock trees, thoroughly eradicate roots and tillers and reduce nutrient consumption. If the surviving branches are grafted, 65,438+0 ~ 2 new buds of the original variety should be kept for replanting in summer and autumn. When the joint is completely healed, the bound plastic film strips can be released to prevent the branches from sinking when they become thicker. When the new shoots are longer than 15cm, it is necessary to bind the columns and fix the new shoots to prevent them from breaking. In order to promote branching, when the branch length is 10 ~ 30cm, the stone should be picked at the required position or branch. (2) Reasonable reshaping should be modified according to the original tree structure. If there is no trunk, we should choose 4-5 main branches with consistent growth, adjust the base angle to 30-40 degrees, and choose 5-6 oblique or backward oblique branches on each main branch with an angle of 70-80 degrees. If the original crown has a trunk but no obvious middle trunk, it can be transformed into a natural happy shape, and three main branches can be cultivated, and the bottom angle is 40-45 degrees. Cultivate 4-5 back branches or 70-80 degree oblique branches on each main branch. If there is an obvious hollow tree, if the tree is young and has a large branching angle, it can be transformed into a spindle shape with 3 ~ 6 main branches. (3) Fertilization For grafted cherry orchard, combined with fertilization, deep ploughing and layered fertilization can be carried out from mid-September of 10 to early October of 10, with a ploughing depth of 50-60 cm, and decomposed manure or human and animal manure should be applied to each plant, 20-30 kg for 2-4 years old and 50-60 kg for adult trees. For example, a garden with a thin soil layer should be cultivated in spring to keep the 50 cm root distribution layer fertile and loose. The fertilization standard of sweet cherry is that the ratio of nitrogen, phosphorus and potassium for adult trees is10 ∶ 4 ∶ 8; 2 ~ 4 years old 10∶3∶6. In the spring of the year after grafting and before germination, each plant was applied with 10 ~ 50 kg of human and animal manure and 1 ~ 1.5 kg of ternary compound fertilizer. Because the growth, flowering, fruit development and ripening of cherry shoots are rapid and concentrated, flower bud differentiation is completed in a short time after harvest, and the demand for fertilizer is relatively concentrated. Topdressing is very important after harvest or before flower bud differentiation. Generally, 20-30 kg of chicken manure or 5 kg of bean cake or 50 kg of human and animal manure water plus 65,438+0-65,438+0.5 kg of compound fertilizer are applied to each tree.
