Gyokuro bergamot pear high-level open-center shape droopy branch fruit shaping and trimming method

Abstract

The invention relates to the technical field of pear tree trimming, in particular to gyokuro bergamot pear high-level open-center shape droopy branch fruit shaping and trimming method, which comprisesthe following steps of: planting pear trees at a density of 70-90 plants per 666.7 square meters; for the ages of 1st-5th years, trimming the pear trees by using a small-crown hydrophobic layer treeshape or a free spinning hammer-shaped tree shape, retaining 10-12 backbone branches for each whole tree; for the ages of 6th-10th years, trimming the trees by using a semi-erect transitional tree shape, carrying out first cadre promoting and head cutting in the middle of the period, for the age of 10th year, preserving 6-8 main branches, and the length of branches of the fruit group is 60-100 centimeters; for the ages of 11th-35th years, trimming the trees by suing an open-center shape, at the age of 30, retaining 3-4 permanent main branches, and the length of the droopy fruit branches is 110-160 centimeters. During the trimming process, as the age of the tree increases, the density of the orchard is gradually reduced through two intermediate cuttings. On the basis of improving the yieldof the orchard, the quality of the fruit of gyokuro bergamot pears is improved.

Description

technical field [0001] The invention discloses a pruning method for shaping and pruning fruit of high happy tree-shaped drooping branches of Yulu fragrant pear, and belongs to the technical field of pear tree-shaped pruning. Background technique [0002] Yulu Fragrant Pear inherits the unique qualities of Korla Fragrant Pear, such as tender meat, sweet taste, no dregs, and red fruit surface, and overcomes the shortcomings of Fragrant Pear, such as small fruit, large heart, low edible rate, and irregular fruit shape. A high-quality, storage-resistant, medium-ripening new variety of Korla pear-shaped large fruit. [0003] Although the quality of Yuluxiang pear is good, the improvement of its yield has always been an important issue, and Yuluxiang pear has a strong top growth advantage, high germination rate and weak branching ability, so pruning is very important in the young tree stage. [0004] At present, pear trees in my country mostly use tree shapes such as free spindle...

Problems solved by technology

The above-mentioned tree-shaped pruning of the orchard has a higher yield at the initial fruiting stage, but the canopy closure and orchard canopy problems generally occur after entering the full-fruit stage, resulting in a decline in fruit tree quality and economic benefits, so tree shape transformation is required
