Abstract: Shading in summer, heat preservation in winter, spraying and pruning treatment were conducted to study their effects on the cut flower yield and quality of Strelitzia reginae. The results showed that shading in summer had no significant effect on the cut flower yield and its first class flower rate, but the second and third class flower rate was increased by 28.6% compared with the opening field; Heat preservation in winter could significantly increase the yield from December of this year to March of the coming year, the yield raised by 182.4% and 19.1% higher in the second and third class rate than that of opening field . When pruning treatment was employed to the 10-age plants, 10-19 individuals were remained in a cluster included in more than 25 individuals, then the yield of the whole year was decreased by 15.1% while the cut flower quality was significantly increased and the first class flower rate was increased by 105.2% compared with the no treatment; With the combination of shading in summer, heat preservation in winter, spraying and pruning treatment, both the whole yield of the cut flower was increased by 30.0% higher than that of opening field after pruning in a year , and the quality was raised, among which the first class flower rate was raised by 37.3%.
