Abstract

Abstract:

In this study, we investigated the effects of different bud loadings and chemical concentrations on the yield and quality components of tea plants using the tea variety Zi Yan as the test material. The results showed that the decrease in flower bud loading could promote the growth of shoots of Zi Yan tea plants, with the highest new shoot yield at 1/2 bud loading, 363.31 kg·hm^-2, 591.38 kg·hm^-2 and 396.76 kg·hm^-2 in summer, autumn and the following spring respectively, which is 28.55%, 49.17% and 125.85% significantly higher than that of the control, respectively. In addition, the reduction of bud loading could also increase the water extract and tea polyphenol content of new tips of Zi Yan tea plants, and facilitate the accumulation of catechins. Ethephon can effectively remove the flowers (buds) of tea plants and maintain them throughout the flowering period, and 1 000 mg·L^-1 of ethephon can significantly increasing the yield of tea plants, amounting to 264.75 kg·hm^-2 in spring. A certain concentration of polyconazole could not effectively reduce the number of flowering of Zi Yan tea plants, and it was observed that it delayed the flowering and new growth process of the tea plants, but did not affect its yield; In addition, polyconazole could significantly increase the free amino acid and anthocyanin content in spring Zi Yan tea plants, with a significant increase of 29.55% in anthocyanin content at a concentration of 150 mg·L^-1 compared with the control.
