Some fruit farmers have some wrong practices in fruit tree winter shears. The specific manifestations are as follows: the tree shape is disordered, the primary and secondary are not distinguished, the verticillate branches are severely stuck necks, the large branches are severely crossed, and the back is bare, which results in the weakness of the central stem or severe skew.
Correction method: According to the planting density, re-define the tree shape, and then determine the main branch according to the requirements of the tree shape. After adjusting the angle and orientation of the main branch, handle the branches other than the main branch. Select the necessary branches on the tree, and thin the whip branches with few branches, few flower buds, and uniaxial extension every year. The fruiting branches that do not affect the growth of the main branch group are taken corresponding measures and used temporarily for fruiting, and then are gradually dredged or retracted into branch groups in stages and batches.
The ultra-high and large tree body is specifically manifested in the low-density orchards that fail to fall down in time after being reshaped, and the crown is out of control, super tall and super large. After such a fruit tree enters the full fruit period, the interplantation is closed and closed, and the inner cavity and the lower layer rarely see light, forming a crown result, and the peripheral result, which becomes a "empty tree" with "full tree results but no yield".
Correction method: In the new year, thin out the big branches except one or two main branches. The big branches with severe shading in the upper part should also be removed, and the other branch groups should be retracted. Select a suitable part to be happy and pay attention to the cultivation of compact type. Resulting branch group; through retraction and dredging, the problem of light in the inner chamber is solved, and the result part is stabilized in the middle of the crown.
