Abstract:
The effects of different root-restriction methods on the growth and fruit quality of blueberry were studied with the 3-year-old blueberry variety ‘Jubilee’.In order to provide a theoretical basis for the production of blueberry roots.Non-woven seedling bags，PVC root control，brick trough and ordinary plastic pots were chosen as root restriction container.The results showed that the restriction cultivation inhibited the nutritional growth and root system composition of the blueberry ramets to different extents，reduced the area of ramets and increased the number of cultivation per unit area compared to control.Sugar accumulation,titratable acidity content,yield and quality of blueberry under root-restriction cultivation.The study suggested that the smallest cultivation volume would make the plant nutrient supply insufficient，because the roots could not be stretched and were entangled in the inside of the root restriction container.We should take care of both the permeability and breath ability of the cultivation container material.These results contribute to a non-woven seedling bags size as 40 cm×35 cm，or the material of PVC control root size (35 cm×35 cm) were suitable for blueberry root restriction production.
