Problems solved by technology

Disadvantages are: the overall shape of the tree body is slow, the result is late, and the early yield is low
The existing problems are: the crown is formed too early, the ventilation and light transmission are poor, and the development of the crown is restricted, and the impact on the later yield is irreversible

Embodiment 1

[0020] A kind of pruning method that improves thin-shell pecan yield, comprises the following steps:

[0021] 1) Pruning at the young tree stage: retract elongated branches, vigorous vegetative branches, and remove over-dense branches; after planting seedlings, set the stem at 1.2-1.5m, and cultivate main trunk branches and main side branches in the first and second years , the third year is mainly to cultivate the fruiting branch group, select one upright branch as the main branch, leave 3-4 main side branches, and evenly distribute in all directions; without affecting the growth of the main side branches, through topping, short Cut to adjust the tree shape, and use summer pruning to pick the heart to cultivate the fruiting branch group;

[0022] 2) Pruning at the initial fruiting stage: 4-5 years after drying, remove overgrown branches, crossed branches, and overlapping branches, so that the branches are strong, evenly distributed, and the tree vigor is open. Cultivate 4-5 g...

Abstract

The invention discloses a pruning method for increasing the yield of carya illinoinensis, and belongs to the technical field of walnut planting. According to the method, by means of bud picking, branch thinning, cutting back, retracting and the like, specific pruning methods are adopted for carya illinoinensis tree shapes in different periods, and the main purpose of pruning in the young tree period of the carya illinoinensis is to culture main branches and main side branches; the main principle of pruning in the early fruiting period of the carya illinoinensis is to continue to culture tree shapes, expand tree crowns, reasonably arrange backbone branches, culture fruiting branch groups and appropriately fruit; and pruning of the carya illinoinensis in the full bearing period is mainly based on culturing of more bearing branch groups. By adopting the method provided by the invention, the relationship among the fruiting branch groups, the main branches and the side branches can be reasonably adjusted, so that the fruiting branch groups are uniformly distributed, illumination is fully utilized, the effective conversion rate of photosynthesis is increased, the fruit quality is improved, the fruiting area is increased, and the fruiting quantity is increased.

Description

technical field [0001] The invention belongs to the technical field of walnut planting, and in particular relates to a pruning method for increasing the yield of pecans with thin shells. Background technique [0002] Thin-shelled hickory belongs to tall tree species. Its growth characteristics are strong trunk, obvious top dominance, relatively late results, and few results in a short period of time. [0003] At present, in the cultivation of pecans with thin shells, the cultivation of fruit-bearing trees mostly adopts the trunk layered type: usually 1-1.5 meters is a fruiting layer, and by manual pruning of 2-3 layers, the early preliminary fruiting tree type is formed. The advantages of this pruning method are: the ventilation and light transmission of the tree body is better, the tree shape is beautiful, the result area is large, and the yield is high. It is suitable for places with better growth conditions and varieties with strong trunks. The disadvantages are: the ov...
