Problems solved by technology

The anthocyanin content of blueberry is an important index to evaluate its quality and nutritional and health value. However, since the main blueberry varieties in my country are imported from Europe, America, Japan and other countries, a set of effective methods for regulating and increasing the anthocyanin content of blueberry has not yet been formed. The management technology system leads to the generally unstable anthocyanin content of blueberry fruit, and the content of the same variety is relatively low compared with foreign countries, so that it is difficult for the fruit to enter the international market for a while, thus limiting the healthy development of the blueberry industry
At home and abroad, a considerable part of the research on anthocyanins in blueberry fruit is still mainly focused on anthocyanin extraction, composition analysis and identification, etc., and seldom involves research on the relationship between anthocyanin content and management methods

Abstract

The invention discloses a management method for improving quality of blueberry fruits. After being planted and cultivated, blueberry seedlings are managed. The management method includes processes ofirrigation, fertilization, pollination, laying of a reflective film, and soil management. The management method has the advantages that the reflective film is laid under a tree in a young fruit stageof blueberries to improve photosynthesis of the blueberries, and accordingly, accumulation of anthocyanin and vitamin C in the fruits is promoted; a bee pollination method is used, and accordingly, the fruiting rate and the weight of a single fruit are increased.

Description

technical field [0001] The invention relates to the technical field of agricultural management, and more particularly to a management method for improving the quality of blueberry fruits. Background technique [0002] Blueberry, also known as lingonberry, blue berry, rhododendron family bilberry, perennial berry shrub fruit tree. The fruit is dark blue, nearly round, and covered with fruit powder. Blueberry fruit is rich in anthocyanins, flavonoids, phenolic acids and other biologically active ingredients and nutrients, and is listed by the United Nations Food and Agriculture Organization as one of the five major healthy foods for human beings. [0003] In the prior art, researches on blueberries mostly focus on planting methods, plant growth and blueberry yield, but neglect the quality of blueberries too much. The anthocyanin content of blueberry is an important indicator for evaluating its quality and nutritional and health care value. However, because the main blueberry...
