Cultivation method for increasing anthocyanin content of blueberries and improving interior quality of blueberries

Abstract

The invention discloses a cultivation method for increasing the anthocyanin content of blueberries and improving the interior quality of the blueberries. The cultivation method comprises the following steps of paving reflective films under a blueberry tree in the earlier stage of coloring of the blueberries so as to improve illumination intensity of inner space of a crown; and prompting photosynthesis and synthesis conveyance of various organic matters in a fruit development period until the blueberries are harvested. By using the cultivation method, the anthocyanin content of the fruits of the blueberries can be remarkably increased; and the vitamin C content, the soluble solid content and the sugar-acid ratio of the fruits of the blueberries are obviously increased. The cultivation method is easy to operate, and is practical and convenient. On the premise of increasing the anthocyanin content of the fruits of the blueberries and improving the other interior quality of the fruits of the blueberries, coloring of the fruits is improved, weeds below the crown are reduced, the sizes of the fruits of the blueberries are large, the weight of each blueberry is relatively heavy, the fruit setting rate is high, and the yield and the quality of the blueberries are effectively improved. Pesticide residue and production cost are reduced while the commodity is improved; and the economic benefit of farmers is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a cultivation method for improving blueberry anthocyanin content and fruit intrinsic quality. Background technique [0002] Blueberry fruit is rich in anthocyanins (anthocyanins) with strong antioxidant properties, which have various physiological activities such as promoting resynthesis of retinoid, anti-inflammation, improving immunity, anti-cardiovascular disease, anti-aging, anti-cancer, etc. Function, due to these effects of blueberries, the consumption market of blueberries has been expanding year by year in recent years. It is called the world's "third-generation fruit" after apples and citrus. Therefore, blueberries have also received more and more attention from the food and health industries. Its products quickly became popular in European, American and Japanese markets, and the price is high, the supply exceeds demand, and it has broad development prospects. ...
