【摘要】[Objectives] To study the effects of different application methods and application rates of biological nano-selenium on the quality of passion fruit. [Methods] In this experiment, passion fruit Tainong 1 was sprayed with biological nano-selenium. The concentration of spraying refers to the recommended application rate of biological nano-selenium manufacturers. Three treatments with different concentrations were carried out: 3, 4.5 and 6 L/ha biological nano-selenium was sprayed on 100% root,(50% root+50% leaf surface) and 100% leaf surface of passion fruit, respectively. [Results] From the aspects of economic cost and rational utilization of resources, spraying 3 L/ha selenium fertilizer on the leaves of passion fruit played the best role in improving the quality of passion fruit. [Conclusions] To study the selenium-rich production technology of agricultural products and improve the quality of agricultural products is of great significance for improving human health and producing high-quality agricultural products.
