Abstract:

The study aimed to investigate the effects of intercropping selenium(Se)-hyperaccumulated plant Cardamine hupingshanensis accompanied with Se spraying on tea plants’ growth,tea quality and rhizosphere enzymatic activities. The tea variety was‘ECha 10’. The Findings indicated that the combination of intercropping combined and Se treatment significantly stimulated the growth of tea plants,showing thicker main stems and a more vigorous root system. It also notably enhanced the content of free amino acid,decreased the content of caffeine,polyphenols of catechin and flavonoids in the young shoots. The primary selenium species in the tea leaves was identified as selenomethionine,followed by selenocysteine. Furthermore,this cultivation practices,intercropping combined with selenium spraying,substantially elevated the activities of β-glucosidase,leucine aminopeptidase,and N-acetyl-β- glucosaminidase in the rhizosphere soil. Conversely,it significantly suppressed the activity sulfatase. Meanwhile,intercropping suppressed the activity of acid phosphatase. In summary,The results highlight that the integration of C. hupingshanensis intercropping combined with selenium foliar spray treatment can synergistically improve tea plants’ growth,enhance the quality of fresh tea leaves,and promote the production of Se-enriched tea. This cultivation practice significantly enhances the enzyme activities of the rhizosphere soil of tea plants.
