Post-harvest pruning method for blueberries in a greenhouse

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...

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
