Abstract: The study aims to clarify the effects of soil moisture preserving methods and boron treatment on photosynthesis of sugarbeet leaves, and the yield and quality of sugrabeet, in order to provide a basis for cultivating drought-resistant, high-yield and high-sugar sugarbeet. The experiment was conducted in 2016. The SPAD value, yield and quality of sugarbeet were determined under different cultivating water treatments and foliar boron application in the middle and late stage. The correlation between SPAD values and the yield and quality was analyzed. The results showed that compared with the control, JF (the ridge mulched with plastic film and furrow cover the straw) water treatment significantly increased sugar yield, boron application improved the sugar content, yield and sugar production in field. For improving the sugar content and yield, JG+ B (the furrow cover the straw+ foliar boron application) had the best effect. JF+B had the best result for improving the yield of sugarbeet. The application of boron increased the SPAD value of sugarbeet leaves, and the SPAD value had the largest gray correlation degree with sugar content of sugarbeet, which had a close relationship. The comprehensive analysis shows that JF can be used as a cultivation model for droughtresistant and water- saving under the ecological condition. Boron application enhances leaf photosynthetic ability and increases yield and sugar content. It is suggested that boron application should be combined with straw mulching (JF+B) in production.
