[Method] With a strawberry cultivar Hongyan as the test material, water, borax and foliar disodium octoborate tetrahydrate was respectively sprayed to the leaves of strawberry four times from the squaring stage on. At the initial flowering stage and mature stage, the plant height, stem diameter, leaf area and petiole length of strawberry were measured; at the harvest time, the single fruit weight of strawberry was measured; and at the mature stage, the VC, sugar and organic acids contents in the strawberry fruit were determined. [Result] Compared with the control group, the spraying of foliar disodi- um octoborate tetrahydrate promoted the growth and significantly increased the plant height and leaf area of strawberry. However, no significant difference was found in root shoot ratio of strawberry between foliar disodium octoborate tetrahydrate treat- ment and the control group. Spraying of boric fertilizers significantly increased the single fruit weight and yield of strawberry. Compare with the control group, the spraying of foliar disodium octoborate tetrahydrate and borax increased the single fruit weight of strawberry by 20.14% and 4.86% respectively, and increased the yield of strawberry by 17.28% and 4.02% respectively. Compared with borax treat- ment and the control group, spraying of foliar disodium octoborate tetrahydrate im- proved the quality, i.e., increased the VC content, soluble solids content and sugar- acid ratio in strawberry fruit. The B content in leaf of strawberry was increased after foliar B fertilization. Among the three groups, the B content in leaf of strawberry ranked as disodium octoborate tetrahydrate treatment＇s 〉 borax treatment＇s 〉 con- trol＇s. [Conclusion] Spraying foliar disodium octoborate tetrahydrate can promote the growth, yield and quality of strawberry.展开更多
