There are many kinds of small apples in cold regions, with wide cultivation area and long supply period. Some varieties are extremely resistant to storage and transportation, with good quality and moderate sweetness and sourness, which are irreplaceable local fruits in the south. According to many years' apple production practice in Jiamusi City, it is proved that the tree shape of "tree trunk with sparse layer and delayed happy shape" is a good tree shape at present, which has the advantages of easy shaping, early fruiting, high yield and long life, and is the main tree shape for apple production in cold areas in northern China. 1 shaping step 1. 1 1 After sowing the seedlings in spring, they will be shaped at a height of 80cm (including 20cm shaping belt), and 3-4 branches will be planted in the shaping belt in the same year. 1.2 In the following spring, the vigorous 1 upright branch was selected as the central stem, with a 40cm short section, and the third bud was cut in the direction of preparing the third main branch. Two branches with proper direction, staggered position and large base angle are selected as the first 1 and the second main branch, and 50 ~ 60 cm short sections are left. The third bud under the incision stays in the direction of preparing the 1 th side branch and should be located on the same side of the two main branches. 1.3 In the spring of the third year, 1 vigorous upright branch was selected as the central trunk, and 60cm short section was left. The branches extracted from the third bud under the cutting in the second year were selected as the third main branches, and 50 ~ 60 cm short sections were left.
