Cultivation method for improving quality of blueberry fruits in Jianghuai region

Abstract

The invention provides a cultivation method for improving the quality of blueberry fruits in Jianghuai region, and relates to the technical field of crop cultivation. The cultivation method comprisesthe following steps: (1) orchard site selection; (2) variety selection and seedling selection; (3) soil improvement method; (4) arranging the rain shelter; (5) high ridge planting; (6) soil management; (7) fertilizer management; (8) water management; (9) flower and fruit management; and (10) light and simple trimming. The varieties of blueberry suitable for cultivation in the Jianghuai region areselected out through experiments over years, the soil acidity and the organic matter are quantitatively regulated by using the ecological method, the fruit cracking rate of blueberry is significantlyreduced through combination of the cultivation mode of "rain-shelter cultivation" with "black film + plastic film" and "high-ridge planting + water fertilizer integrated drip irrigation", the degree of of fruit powder integrity is high, and single fruit weight, soluble solids, titratable acid, vitamin C and total anthocyanin are significantly higher than those of conventional cultivation and the economic benefits of blueberry production are significantly improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method for improving the fruit quality of blueberries in the Jianghuai region. Background technique [0002] Blueberry belongs to the Vaccinium genus and is an important small berry fruit tree. It is rich in anthocyanins and various antioxidant substances, such as anthocyanins, proanthocyanidins, flavonols, and vitamin C, vitamin E and other nutrients. It has health care functions such as softening blood vessels and enhancing human immunity, and is favored by consumers. The market demand for blueberries in my country has also increased dramatically year-on-year. Compared with 10 years ago, the planting area of ​​blueberries in the Jianghuai region has increased by more than 8 times. At the same time, consumers have higher and higher requirements for the quality of blueberries. [0003] However, there are following problems in the production of blueberries ...

AI Technical Summary

Problems solved by technology

However, there are blind soil improvement in actual production, that is, the specific dosage of soil regulating substances is not clear, which directly affects the normal growth of blueberries; or chemical elements such as sulfur and ferrous sulfate are directly applied to the soil to reduce the pH value, blindly pursuing blueberry production, ignoring damage and pollution to the soil

[0005] The second is the blind selection of varieties and the decline in economic benefits

There are a large number of cultivated blueberry varieties, but the varieties suitable for the climatic conditions in the Jianghuai area are limited. However, most "berry farmers" do not have the concept of "variety adaptability", which makes the imported varieties unsuitable for planting in the Jianghuai area. Insufficient quantity, etc., cannot bloom and bear fruit normally, there is almost no yield and benefit in production, and huge economic losses

[0006] The third is heavy rainfall, which directly affects fruit quality and fruit harvesting

In actual production, heavy rainfall during the causal and fruiting period causes higher water content, lower sugar content, lower taste, and lower storability of the fruit; it also often causes the phenomenon of "cracking" of blueberry fruits; The "fruit powder" on the surface of the fruit is incomplete and the commerciality is reduced

In addition, the ripening of blueberries in the Jianghuai area coincides with the "rainy season", and the continuous rainfall also prevents workers from going to the field to harvest

[0007] The fourth is improper soil management, causing waterlogging and plant death

In actual production, due to the unscientific surface drainage in the park, the blueberry plants will accumulate water, resulting in flowering, fruit setting, poor growth, or plant death
