Cranberry, also known as cranberry, is a plant of Vaccinium in Ericaceae.

Cranberries mainly grow in the cold northern hemisphere, limited to the northern part of M country and Quebec and Columbia in Canada, as well as Chile in South America and a small piece of northeast Europe. It is also common in Daxinganling area of China. The output of country M accounts for 95% of the world's total, among which Wisconsin ranks 1, accounting for 50% of the total output of country M, and Massachusetts ranks second with 28% of the total output. The increase in output stems from the continuous increase in demand for cranberry products. Because cranberry fruits are not resistant to storage and transportation, they are usually sold as frozen fruits or processed into canned products, jams and juices.

In 20 19, the Red Sea cranberry base in Fuyuan City, Heilongjiang Province, China ushered in a bumper harvest, which broke the situation that domestic cranberry supply depended on imports and officially opened the first year of domestic cranberries.

As of 20 19, the planting area of cranberries in China is about 4200 mu, which is also the largest cranberry planting base in Asia.

There are wet and dry harvesting methods for cranberries. Most of them are harvested by wet method, and the fruit growers inject water into the cranberry fields to make the water surface higher than cranberry vines 15 to 20 cm, and the cranberries float to the water surface, and the fruit growers circle the fruits together and send them to the trucks through the conveyor belt. Dry harvesting is to use a picking machine with a comb-shaped conveyor belt. The picking machine picks cranberries from the branches, directly transports them to sacks, and then loads them for transportation. Cranberry harvested by dry method only accounts for 5% to 10% of its total mass, and is mainly sold in the form of fresh fruit.
