First, plastic shelves
After the young seedlings resumed their growth, the buds were wiped once every 5 days, which promoted the growth of the main vines. When the main vine grows to 40 to 50 centimeters, it is necessary to insert the pillars in time to guide the main vines to the shelves. After the main vine is put on the shelf, it is often necessary to induce the side vines to spirally grow on the wire frame, and after the side is covered with the shelves, the broken top is tied. The side vines are one branch on the side, which will help to draw the results as soon as possible.
Second, the young tree shaping
Single main vine double layer four branch shaping method, when the main cranium grows to 70 to 80 centimeters while leaving side vines 2, respectively, traction on the shelves, as the main vine on the first floor. When the plant grows to 150-160 centimeters, one branch of strong lateral branch is left and the main branch of the main vine is also used as the main branch of the second floor. The traction is pulled in the opposite direction to form a double-branched branch. During this period, the lateral branches and the buds below 80 cm and 80 to 160 cm should be cut off or erased.
Third, the old tree shaping
The shoots that germinated after fruit picking in the previous year were found in almost all the sections above the middle. Last year, as much as possible to leave the results of the mother branch, but in order to prevent the shed is too dense, as soon as possible after the fruit pruning. Leave the vines on the two main branches. Branches near the stems are first filled with fruit. After ripening, they are trimmed to 2-3 knots. The buds that sprout from the base of the main branch can form new branches. After the last fruits of the winter were harvested, all the resulting branches were trimmed from the base.
