Greenhouse blueberry post-harvest pruning method

Abstract

The invention provides a greenhouse blueberry post-harvest pruning method, and relates to the technical field of fruit tree pruning. A set of post-harvest pruning closed-loop technical system is established for the first time based on the post-harvest pruning concept of branch production and cultivation, branch yield determination, high-quality fruiting and simplified pruning. According to the method, the high-yield tree type suitable for blueberry production is determined, the technical standard of the tree type is quantified, and meanwhile, the industrial yield standard in post-harvest pruning fruiting mother branch culture and in the yield which is not lower than 1 ton of fruits per mu is quantified. According to the method, the optimal branch remaining amount is determined by determining the technical standards of selection, number and thickness of fruiting mother branches and the technical standards of the number and yield of formed fruiting branches, meanwhile, the pruning operation technical standard of branch shaving of fruiting mother branch culture is combined, the post-harvest pruning operation technical standard and process are established, operation is standard and process-oriented, and the method is suitable for large-scale popularization and application; and industrial trimming and modeling production becomes possible. The method is wide in system applicability and can be suitable for all greenhouse south highbush and north highbush blueberry varieties.

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
