Shanghai develops blueberry planting technology to revitalize local agriculture

Right now, it's exactly the season when blueberries are ripe in the greenhouse. In the greenhouse of the Shanghai Academy of Agricultural Sciences, blueberries used for scientific research also entered the period for picking.

From the perspective of the development process and current situation of blueberries in the world, the blueberry industry is in the developing stage with broad prospects in China, and besides, blueberry planting conditions are sensitive.

"Blueberries, like the well-known strawberry planting, are economic crops with high yield per hectare. The difference is that strawberries are planted once a year and the technology is already relatively mature, while blueberries are perennial shrubs that require harsh acidic soil conditions. The relevant research is also in the development stage." A blueberry researcher from the Shanghai Academy of Agricultural Sciences explains. "Therefore, the protected cultivation of blueberries with substrate and nutrient solution has developed rapidly. This model of plant growth is fast, and it can be put into production just in the second year of planting, and the output is as high as 11250-15000 kg per hectare."

The mixed substrate is ​​made up of peat, cocopeat, and perlite in a specific proportion. After blueberries are transplanted in it, they can get rid of the influence of the soil. The dripping irrigation system combines the nutritional needs of each stage to achieve green, safe, efficient, high-quality, and high-yield. This cultivation mode of "substrate + nutrient solution" provides technical support for the further development of the blueberry industry in Shanghai.

Small blueberries also have a big effect
The green planting of blueberries is also expected to have a positive impact on rural revitalization and the integration of agriculture in the Yangtze River Delta. Traditionally planted Shanghai blueberries are ripe in June and July and are mainly picked by farmers. But if using the protected cultivation combined with heating, the ripe period can be advanced to mid-March at the earliest and last to early June, which coincides with the ripe period of open-field cultivation and enriches the fresh fruit supply in the first half of the year in Shanghai. ;

The Shanghai Academy of Agricultural Sciences has joined forces with Wufang Village, a demonstration village for rural revitalization in Shanghai, to explore the shared planting model of blueberry picking and potted blueberries into the household.
