Abstract
The invention discloses a method for strong seedling and rooting culture of strawberries, which includes the following steps: firstly, strong seedling and rooting culture: a multiple shoot with a prophyll and 0.3-0.5 cm in height and well in growth and development is cut into a single plant and transplanted to a strong seedling and rooting culture medium for rooting culture, and transplanting is carried out after the plant is 3-5 cm in height; secondly, transplantation: the plant is firstly transplanted to a culture room and grows for 30-35 d, then is transplanted in a plastic-covered tunnel with a shading net, after a new root grows and the plant sprouts, watering frequency is gradually reduced, and the plant is transplanted to a flowerpot for ordinary management. The method for strong seedling and rooting culture of strawberries, provided by the invention, improves the survival rate of transplanted plants by 90% above through supporting measures such as improvement on minimal medium and ingredients and adjustment in culture conditions, enables seedlings to grow healthy, effectively solves the problem of genetical characterization decline of fine seedlings, effectively improves yield and quality of strawberries and enhances the economic value of strawberries at the same time.
