Apple closed garden transformation technology

The density of red Fuji apple trees planted in the past was mostly 23 meters. Due to the excessive planting density, they did not strictly perform pruning according to the free-spindle-shaped tree structure, resulting in oversized trees, disordered structures, and inter-tree rows. Inter-crossings, deterioration of the light conditions, the results of the drag group lengthy branches, the internal litchi group is extremely weak, the resulting parts of the shift, yield and quality decline. Therefore, we must pay close attention to timely reconstruction, and now we have to talk about transformation techniques in the two situations that have not yet completely closed and closed planting orchards.

(I) The technology of transforming the closed planting garden

According to the specific situation, the temporary and permanent plants should be distinguished. The use of crown control and flower-promoting measures for temporary plants allows them to achieve multiple results; for permanent plants, they are required to be plastically trimmed and pruned normally, with appropriate results; when they affect each other, temporary plants give way to permanent plants, after two or three years, The temporary plants are completely cut off, and the purpose of changing the density to prevent the closure of the forest is achieved.

(II) Reconstruction Technology of Closed Garden

The rebuilding of closed apple orchards can be resolved from three aspects. That is: to tree, branch and change thoroughbred.

1. To the tree: The thinning is done between septa or interlace, and thinning can also be carried out by using thinning to expand the orchard area.

2. Debranching: Debranching can be carried out by firstly gathering septum interlaced, and after two or three years, deforestation will be carried out. It is also possible to remove large branches, rough branches, and strong branches that cross each other to achieve the purpose of ventilation and light transmission. Then there is a tree that is too tall on the tree.

3. Replacement of thoroughbreds: This method can be used for old, poor, poor, and miscellaneous enclosed gardens. You can use septum or interlacing for better performance. The grafting method is based on the structure of a spheroidal tree and is carried out by a near-dry grafting method. When the tree crown is to be changed and the result has been changed, the unaltered tree is cut off.
