Effects of Different Application Methods and Application Rates of Biological Nano-Selenium on the Quality of Passion Fruit

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.
