Other claims from this paper (13)
- Intervention effect Theanine in tea leaves increased by 52.87% under intercropping with soybean–Chinese milk vetch rotation.
- Intervention effect Theanine in tea leaves increased by 40.98% under intercropping with soybean alone.
- Intervention effect Epigallocatechin gallate in tea leaves increased by 22.80% under intercropping with soybean–Chinese milk vetch rotation.
- Intervention effect Epigallocatechin gallate in tea leaves increased by 6.17% under intercropping with soybean alone.
- Intervention effect Soluble sugar in tea leaves increased by 22.22% under intercropping with soybean–Chinese milk vetch rotation.
- Intervention effect Soluble sugar in tea leaves increased by 29.04% under intercropping with soybean alone.
- Intervention effect Intercropping significantly increased soil amino acid nitrogen content in the tea plantation.
- Intervention effect Intercropping enhanced soil extracellular enzyme activities, particularly beta-glucosidase and N-acetyl-glucosaminidase.
- Intervention effect Intercropping enhanced soil multifunctionality.
- Intervention effect Metagenomics showed that intercropping positively influenced the relative abundances of potentially beneficial microorganisms such as Burkholderia, Mycolicibacterium and Paraburkholderia.
- Intervention effect Expression of nrfA/H increased significantly under intercropping with soybean–Chinese milk vetch rotation.
- Mechanism Structural equation modelling indicated that theanine accumulation in tea leaves was directly influenced by the number of intercropped green manure species, soil ammonium nitrogen and soil amino acid nitrogen.
- Recommendation Intercropping with soybean–Chinese milk vetch rotation could be a novel way to increase theanine accumulation in tea.
