Abstract:
The soil in the representative tea garden of Fuding white tea and the corresponding tea samples were collected to analyze the effects of different parent materials, planting years and planting varieties on the available zinc in soil and the zinc in tea leaves. The results showed that:the average content of available zinc in the soil of Fuding white tea garden was 2.65 mg·kg
-1, and the content of available zinc in the tea garden with granite soil and the content of zinc in tea leaves were lower than the average value of the survey sampling points; the content of available zinc in soil increased with the increase of tea planting years, and the content of available zinc in the soil planted small white tea was lower than the critical value of zinc deficiency in soil, and there was a very significant linear correlation between the zinc content in white tea and the available zinc in soil. The zinc content in the soil of Fuding white tea gardens was relatively low on the whole. Therefore, the corresponding measures should be taken according to the soil in different tea gardens, including the scientific fertilization and the application of organic fertilizer to improve the soil nutrient content, so as to increase the zinc content of tea.
