Abstract:

To explore the potential of bio-nano-selenium fertilizer as a replacement for chemical fertilizer in improving fruit quality of Hongmeiren citrus and enhancing soil nutrients,this study compared and analyzed the effects of different replacement ratios of bio-nano-selenium fertilizer. The results showed that the application of bio-nano-selenium fertilizer increased the selenium content,single fruit weight,soluble solid content,and sugar-acid ratio in the fruit. Considering all indicators,treatment T5(60% replacement of chemical fertilizer by bio-nano-selenium fertilizer)ranked first overall,with its yield increasing by 45.70% compared with CK. Under this treatment,soil nutrient contents were more appropriate,maintaining soil nitrogen content,alleviating phosphorus loss,and keeping a relatively high potassium content. This study can provide a reference for reducing chemical fertilizer application,improving quality and efficiency in Hongmeiren citrus production.
