锌是茶树必需的微量元素,已发现锌参与 IAA 前体色氨酸的合成。锌的不足,茶树幼嫩部位不能正常生长。多年生植物尤其是茶树,不断采摘幼嫩部分,带走了大量的锌。由于从土壤中吸收的锌不能维持茶树正常需要,因而表现出缺锌症状。虽然酸性土壤中锌的有效性不成问题,但据报道,锌从 Zinc is an essential trace element for tea and zinc has been found to be involved in the synthesis of the tryptophan IAA precursor. Insufficient zinc, young parts of tea can not grow normally. Perennials, especially tea trees, continue to pick the young part, taking away a lot of zinc. Zinc deficiency manifests itself as zinc absorbed from the soil can not maintain its normal needs. Although the effectiveness of zinc in acidic soils is not a problem, it has been reported that zinc is from
