[0034] A kind of dwarf stock Fuji apple sapling controls crown and promotes flowering high-yield method, comprises steps as follows:
[0035] 1) After the seedlings are planted in spring, from late May to early June of that year, when the new shoots germinated on the central trunk of the young trees grow to 25cm, use a bamboo toothpick with a tip length of 12-15cm at both ends, and insert one end into a new shoot that needs to be opened. The other end is inserted into the center trunk in the bark of the shoot, and the new shoot is opened and pulled, so that the opening angle of the new shoot reaches 80°, and the opening angle is 3cm away from the base of the shoot.
[0036] 2) When the new shoot grows to 40cm, remove the top 4cm of the new shoot for the first topping, to control the extension and growth of the new shoot, and promote the germination of short and medium branches at the rear end of the topping part; when the top axillary buds and auxiliary shoots grow to 35cm afte...
Embodiment 2
[0041] A kind of dwarf stock Fuji apple sapling controls crown and promotes flowering high-yield method, comprises steps as follows:
[0042] 1) After the seedlings are planted in spring, from late May to early June of that year, when the new shoots germinated on the central trunk of the young trees grow to 28cm, use a bamboo toothpick with a tip length of 12-15cm at both ends, and insert one end into the new shoot that needs to be opened. In the bark of the tip, insert the other end into the central trunk, and pull the new shoot at an angle to make the opening angle of the new shoot reach 78°, and the opening angle position is 4cm away from the base of the tip.
[0043] 2) When the new shoot grows to 45cm, remove the top 5cm of the new shoot for the first topping, control the extension and growth of the new shoot, and promote the germination of short and medium branches at the rear end of the topping part; when the top axillary buds grow to 40cm after topping At the same time...
