Ripening picking time of blueberry
The maturity of blueberries is around July every year, and the artificially planted blueberries mature earlier and can be listed around June. The maturity of wild blueberries in China is between July and August every year.
Ripe blueberry fruit is blue. Blueberry fruit is rich in anthocyanins and has high edible value. When choosing blueberries, be sure to choose fresh ones. The more obvious the frost on the skin, the fresher it is.
Picking methods and key points of blueberries
When picking blueberries by hand, they need to be harvested according to the size and maturity of the fruits, and then sent to the fruit market. In developed countries, due to the lack of labor resources, more and more people use mechanical harvesting to pick blueberries.
However, this method also has problems. The loss of mechanical harvesting is greater than that of manual harvesting, and the fruits harvested by mechanical harvesting need to go through strict packaging procedures.
Blueberries will be preserved after harvest.
A blueberry tree over 5 years old can produce about 7 kilograms of blueberries. If stored at low temperature, its fresh-keeping time will be longer, up to about 3 months. Vacuum cooling is faster, and cold air cooling fruit is of high use value, but the cooling speed is slower when there is an outer packaging box. In order to realize heat exchange as soon as possible, holes can be punched in the outer packaging.
