摘要
盆栽试验研究了N、P二要素对茶条槭组培苗生长和光合特性的影响。结果表明,随着氮肥、磷肥水平的提高,植株的株高、地径都有所增加,根冠比减小,光合产物向茎叶转移;适量施用氮、磷肥有助于提高植株的光合作用以及水分利用率。
By means of pot culture,the effects of different fertilization levels on growth and photosynthetic characteristics of Acer ginnala were preliminarily explored in order to provide the basis for proper application of nitrogen and phosphorus fertilization for potted plants.The results showed that the plant height and ground diameter of potted plants all increased with nitrogen and phosphorus rates.The root/shoot ratio was decreased,indicating that the photosynthates were transferred to stems and leaves.The proper amount of nitrogen and phosphorus could improve photosynthesis and water use efficiency in potted plants.
