The naturally grown apricot tree is round-headed before the result, and after several years of results, it gradually becomes broad-circle or semi-circular. This kind of tree has many internal branches and confusion. The main and lateral branches are not clear. Although the results are relatively early, the tree vigor weakens after a large number of results. The result is that the site moves upwards, the lower part of the canopy and the introvert are bald, and the continuous result ability is low. Pruning can make the tree body and branches firm, reasonable structure, can fully accept and use light energy, make the tree early results, early high yield, fruit quality is good, the economic life of the tree is prolonged. At present, there are several types of trees commonly used in production: Evacuation layered This kind of tree has obvious central leadership. 6 to 8 main branches are layered on the central leadership. The first layer has 3 to 4 main branches, the second layer has 2 to 3 main branches, and the third Layer 1 to 2 main branches. The main branches were planted with lateral branches, with a distance of 40-60 cm before and after, and the resulting short branches and resultant branches were produced on the lateral branches. The tree-shaped crown is tall, the trunk is obvious, the main branch is layered, the internal light is good, the internal ridge is not easy to empty, the branches are large, the fruit yield is high, the quality is good, and the economic life of the tree is long. Natural round shape This kind of tree has no obvious central leadership. There are 5 to 6 main branches in the trunk. One of the main branches extends upward into the interior of the crown, while the other main branches are inserted diagonally and inserted in a staggered manner. Each main branch is Leave a lateral branch every 40-50 cm, and the lateral branches are distributed evenly up and down. This type of tree pruning has a small amount and can be formed within 3 to 4 years after planting. The result is early and easy to manage. Naturally happy This kind of tree has no center trunk. The main trunk is about 50 centimeters high. The trunk has three to four evenly spaced main branches. A number of lateral branches were planted on each main branch, which were arranged along the main branch. The distance between the front and rear branches was about 50 cm. Lateral branches bear short and fruiting branches. The natural happy-shaped tree is small, the main branch is open, and the ventilation and light transmission are good. The result is that the branch is firm and full, the service life is longer, and the fruit quality is also good.
