Abstract：Taking strawberry（Fragaria ananassa Duch.） cultivars‘ Akihime’ as test material，this study measured the strawberry seedlings’ plant height，petiole length，new stem diameter，leaf area and the SPAD value，etc．plant growth quantity and root length，fresh root quality，fresh and dry plant qualities，etc．biomass of the 2 different breeding modes．The paper also analyzes the growth vigour of strawberry seedings cultivated by 2 breeding modes after transplanting into the greenhouse with heat storage type cubic strawberry cultivation system．Besides，the solar radiation energy，temperature of the canopy above and relative humidity in these 2 nursery greenhouses were tested，respectively．The results showed that all the indexes of the strawberry seedling growth quantity and biomass in the elevated strawberry nursery greenhouse were better than that of the seedling grown in the common greenhouse，and their seedling reviving time was shorter and growth vigour even more flourishing．So the environment condition of elevated strawberry nursery greenhouse was obviously superior to that of the common greenhouse，and was more favourable to strawberry seedlin gs’ photosynthesis.
