Problems solved by technology

However, the producers of Red Fuji generally believe that it is difficult for the Red Fuji variety to flower, and the management is labor-intensive.
The results of the traditional branch group culture method are late and the yield is low

Embodiment 1

[0034] The pruning of embodiment 1 spindle-shaped orchard

[0035] Described spindle-shaped orchard comprises tall spindle, fine spindle and free spindle, and concrete cultivation and pruning method are:

[0036] In the winter of the second year after the fruit tree seedlings are planted, remove the branches below 80 cm from the ground for the branches sent out on the central leading trunk, and keep the branches above 80 cm above the ground and the same side branch spacing is 0.2 to 0.7 m (trees) Different shapes and different spacings), the retained branches are cultivated as large-scale fruiting branches (not as main branches); the central leading trunk is from 80cm upwards and the spacing of the same side of different tree shapes is different, and the free spindle shape is 0.7m. Thin spindle shape 0.5m, high spindle shape 0.2m;

[0037] In the summer and autumn of the third year, when the branch length exceeds 50% of the line spacing, hold the branch with the left hand and...

Embodiment 2

[0041] The pruning of embodiment 2 small crown shape and pistachio orchard

[0042] Within 3 to 5 years after the fruit tree seedlings are planted, keep and cultivate 6 to 10 main branches on the central leading trunk. 180 degrees, close to the drooping state; cultivate a large-scale fruiting branch group every 40-60cm on the main branch, and between the large-scale fruiting branch groups, use the long branches to cultivate the fruiting branch group to cultivate small and medium-sized fruiting branch groups.

[0043] Generally, 40 trees are planted per mu in small crown-shaped and pistachio-shaped orchards, and each fruit tree has 30-40 large-scale fruiting branches (4-8 of which are cultivated on one main branch), 60-80 medium-sized fruiting branches, and small-sized fruiting branches. Groups of 300-400, through the effect of fruit gravity, these fruiting branch groups will naturally be in a drooping or oblique state.

[0044] When it is found that the fruiting branch group ...

Abstract

The invention discloses a culture and updating pruning method for bearing branch groups of red fuji apples. The method comprises the following steps of: culturing large-sized bearing branch groups on each fruit tree, and culturing medium-sized bearing branch groups and small-sized bearing branch groups in the large-sized bearing branch groups or among the large-sized bearing branch groups, wherein in a high yield period, fruit trees per mu comprise 1,200 to 1,600 small-sized bearing branch groups, 240 to 320 medium-sized bearing branch groups and 120 to 160 large-sized bearing branch groups in a spindle-shaped fruit ranch, and when branch ages of the bearing branch groups are between 4 and 5 years, updating rejuvenation is performed once every winter. The culture and updating pruning method for the bearing branch groups of the red fuji apples is a good culture method for the large-sized bearing branch groups, and the defects of late bearing and low yield which are caused by the conventional culture method for the bearing branch groups are thus overcome.

Description

technical field [0001] The invention belongs to the technical field of apple tree shaping and pruning, and relates to a method for cultivating, renewing and pruning fruiting branch groups of red Fuji apples. Background technique [0002] Plastic pruning is an important technical measure in the cultivation and management of apple trees. It needs to be adapted to local conditions, tree conditions, flexible control, and dynamic pruning according to the biological characteristics of the variety, the basic law of pruning responses, and the specific performance in the local area. achieve better results. Results The cultivation and renewal of branch groups is a very important link in the pruning technology of apple trees, and it is also a technology that is relatively complicated and labor-intensive in the pruning and pruning of apple trees. [0003] Apple fruiting branch group is the most basic fruiting unit of the apple tree, and apple yield and quality are closely related to th...
