Can BlackBerrys be grown in North China?

BlackBerry cannot be planted in the north, because of its high demand for land and environment, blackberries are planted in Hubei, Jiangxi, Hunan, Sichuan, Chongqing and other provinces in China, and blackberries are not suitable for preservation, but are generally processed into frozen fruits for export to Europe and the United States. BlackBerry must be sterilized and frozen within 4 hours after picking, so it is almost impossible to buy fresh BlackBerry fruit on the market.

BlackBerry is not suitable for planting in Northeast China because of its high demand for land and environment, while Shandong, Henan, Hebei, Anhui, Shaanxi, Zhejiang, Hubei, Jiangxi, Hunan, Sichuan, Chongqing and Guizhou provinces are important bases for BlackBerry cultivation. Blackberries should not be preserved. They must be cleaned, sterilized and frozen immediately 4 hours after picking, otherwise nutrients will be lost and fermented. Blackberries produced in China are mainly processed into frozen fruits and exported to Europe and the United States, so fresh blackberries are not available on the market.

Planting conditions of BlackBerry

BlackBerry planting requires a high degree of soil moisture and fertility. BlackBerry growth is creeping upward, with sharp thorns on the stem. When the stem bends and falls, the branches will touch the ground, and the top nodes of the branches will grow roots. Because of this characteristic, BlackBerry growing in woodlands, bushes and hillsides can occupy a large area of land in a very short time.

Flowers that bloom earlier can produce more drupes than those who bloom later, which suggests the following possibilities: depletion of root nutrients, a decrease in the number of pollinators, and changes in the state of the environment. bees are unable to work after the morning in rainy or too hot weather, which leads to a decrease in pollination and the fruit quality is not as good as that of previous flowers.

The small drupe of the BlackBerry mainly grows near the ovule, and the male gamete in the pollen grain is ovule fertilization. The BlackBerry ripens during the period from the end of June to the beginning of August, because the BlackBerry is a delicate fruit and must be picked manually, so it takes a lot of labor.

Because BlackBerry is rich in anthocyanins, selenium and other highly effective antioxidant substances, as well as amino acids and trace elements needed by the human body, BlackBerry is recognized as the third generation of special fruit by the Food and Agriculture Organization of the United Nations, and it also enjoys the reputation of "fruit of life" and "black diamond".
