AI Technical Summary

Problems solved by technology

The above three types of pruning all adopt basic pruning methods such as short cutting, retraction, thinning, topping, etc., generally refer to traditional methods or methods such as apples, peaches, plums, and apricots, and the operating standards are generally based on experience or the behavior of other fruit trees. Operation, the research on blueberry pruning response is not deep, and a relatively complete technical system has not been formed

Embodiment 1

[0039] North High Variety

[0040] (1) Northland

[0041] Determine different pruning times and corresponding pruning modes according to the end time of fruit harvesting. Mainly in mode A, after the pruning time of mode A, execute mode B and mode C:

[0042] A. Post-harvest cutting time is from June 1st to June 20th, cut off the new shoots of the year, and leave 15-25 fruiting mother branches (tasong-shaped distribution, the middle main arbuscular branch at a height of 110-120cm is the highest layer, 2-3 fruiting mother branches are distributed; the height of 70-100cm is the middle layer, and 8-15 fruiting mother branches are distributed; the height of 30-40cm is the bottom layer, and 5-7 fruiting mother branches are distributed), and the summer pruning time is From July 15th to 25th (choose 2 to 3 upright new shoots on each of the above-mentioned fruiting mother branches, and carry out pinching or short cutting), the autumn pruning time is from September 10th to 20th, and it ...

Embodiment 2

[0048] South High Variety

[0049] (1) O'Neal cut after harvest from May 25th to June 5th, and kept 20-25 fruiting mother branches (tasong-shaped distribution, the middle main arbuscular branch at a height of 110-120cm is the highest layer , distribution of 3 to 4 fruiting mother branches; 70 to 100 cm height is the middle layer, 12 to 15 fruiting mother branches are distributed; 30 to 40 cm height is the bottom layer, and 5 to 6 fruiting mother branches are distributed), mid-July Carry out summer pruning in the last ten days of a month (choose to stay 2~3 upright new shoots on each described fruiting mother branch and carry out topping or short cutting), carry out autumn pruning in mid-September, and form 160~200 fruiting branches in mid-October. After dormancy and before warming up, the fixed branches are pruned, and 80-120 fruiting branches are left after cutting. The yield per plant is 8-10 catties, and the yield per mu is 2000-2500 catties.

Abstract

The invention provides a postharvest pruning method for blueberries in a greenhouse, and relates to the technical field of fruit tree pruning. Pruning closed-loop technical system. The method of the present invention establishes a high-yield tree type suitable for blueberry production, quantifies the technical standard of the tree type, and simultaneously quantifies the industry output standard of cultivating mother branches after harvesting and pruning results and fruit yield per mu not less than 1 ton. The method of the present invention determines the optimal amount of remaining branches by determining the selection, quantity, thickness, and the number and output of the resulting mother branches, and at the same time combines the technical standards for the "branch shaving" pruning operation of the resulting mother branches to cultivate, Established technical standards and procedures for postharvest pruning operations, making operations standardized and streamlined, and making industrial pruning model production possible. The method system of the invention has wide applicability and can be applied to all blueberry varieties of southern highbush and northern highbush in greenhouses.

Description

technical field [0001] The invention belongs to the technical field of fruit tree pruning, in particular to a postharvest pruning method for blueberries in a greenhouse. Background technique [0002] In recent years, with the rapid development of the blueberry industry in China, the area of ​​greenhouse blueberries in the northern region, especially in Liaoning, has gradually expanded, and it has developed explosively in the past three years. Liaoning has become the region with the largest scale of industrialization of greenhouse blueberry planting. Liaoning has the earliest greenhouse cultivation production technology and research, and there are many planting enterprises and farmers. Since greenhouse cultivation technology is a new field, they are all in the initial stage, and they are researched and developed independently, forming their own system, resulting in non-standard cultivation technology. Especially the post-harvest pruning technology has not formed a scientific...
