Abstract: Ecological conditions in tea plantation were effectively improved by intercropping trellisedgrapes and tea.The tea plantation under 40—50% of shading was keeping the sunlightillumination intensity at 20000—40000 Lx,In this way,the physiology of buds was well-regulated;the growth of new shoots and the effective components in the tea leaves wereincreased.Then,the quality of the tea was improved.Moreover,the economic benefit wasenhanced by the intercropping.It was discussed that the grape stains,their culture andtrellises were selected to fit the intercropping.
