摘要:
以福鼎大白一年生茶树(Camellia sinensis)扦插苗为材料,研究了钙在铝胁迫下对茶树钙铝及其他矿质营养吸收积累的影响.结果表明:适量的铝添加(10 mg/L 和20 mg/L)能促进茶树对铝的吸收和积累,铝添加降低根对钙的吸收但不影响茎和叶对钙的积累.而钙添加降低茶树各器官对铝的吸收和积累,增加钙的吸收和积累.适量铝添加能促进茶树根、茎和叶(老叶和茶叶)对钾和铁的吸收与积累,降低根对镁和锌的吸收与积累,但茎和叶中镁和锌的含量继续增加.钙增加茶树对钾的吸收和积累,对铁没有明显的影响.钙降低茶树对镁和锌的吸收和积累,但仍高于对照组.综合来看,在铝胁迫下,增加培养液中钙的浓度能够降低茶叶中铝的含量,增加茶叶中钙的含量,对其他矿质元素的利用没有不利影响.因此,在茶园中适当增施钙可以降低茶叶中铝的含量,提高茶叶的安全性
Abstract:
The effects of Ca addition on uptake and accumulation of Ca, Al and other mineral nutrition of tea plants were studied with one-year cutting seedlings of varity fudingdabai. The results showed that suitable Al addition (10 mg?L?1and 20 mg?L?1) increased Al uptake and accumulation of tea plants. Al addition decreased Ca uptake by roots of tea plants, but have no effects on accumulation of Ca in shoots and leaves. Ca addition decreased Al uptake and accumulation of tea plants, but increased Ca uptake and accumulation. Suitable Al addition increased uptake and accumulation of K and Fe of roots, shoots and leaves of tea plants, decreased uptake and accumulation of Mg and Zn of roots, but the content of Mg and Zn of shoots and leaves continue to increase. Ca addition increased uptake and accumulation of K and had no effects on Fe uptake and accumulation of tea plants. Ca decreased uptake and accumulation of Mg and Zn of tea plant. While Mg and Zn content of tea plants treated with Ca was not less than that of control (no Al addition and normal Ca). Taken together, suitable Ca can decreased Al content and increased Ca content of tea leaves, and had no effects on other mineral nutrition for the use of tea plants. Thus, application of Ca in tea garden can increase Ca and decrease Al content of tea leaves, and thus increase the security of tea leaves.
