摘要
研究了不同程度遮阴处理(25%,50%)对温室盆栽茶梅叶片内营养物质含量的影响。结果表明,不同程度遮阴处理对茶梅叶片中各种营养物质含量的影响不同,随着遮阴程度的加大,叶片中的可溶性糖含量、淀粉含量和可溶性蛋白质含量都逐渐下降,而含氮量有所提高,碳氮比下降。由此可见,遮阴不利于茶梅叶片内营养物质的积累。
The leave nutrients of GameUia sasangua in greenhouse under different shading treatments of 25% and 50% were studied. The results indicated the leave nutrients of Gamellia sasangua are distinct under different shading. As the degree of shading increased, leaf soluble sugar contents, starch contents and soluble protein contents decreased gradually, while the nitrogen contents in leaves increased and C/N contents dropped. It suggested that shading treatments of GameUia sasangua were not conducive to the accumulation of nutrients.
