玫瑰的营养水平及其土壤环境

本文对平阴玫瑰的叶片营养水平、生长状况及其土壤条件进行测定。结果表明生长状况不同的玫瑰植株叶片中磷和钙的含量差异明显,其它元素差别甚小,但养分含量之间的比率表现不同。土壤的物理性质,尤其是粗砂、石砾的含量、土壤容重和土壤孔隙状况,可能是影响玫瑰根系生民和产花量的重要原因。文中将平阴玫瑰产地的立地环境与保加利亚玫瑰产地相比较,拟为开发玫瑰选择适宜条件提供参考。

The Nutrition Level of Rose and lts Soil Condition

In the paper, the leaf nutrition level of Pingyin rose and its growth status, as well as its soil conditions were measured. Results indicate that: the rose plants with different growth status showed marked variation of phosphorus and calcium content in their leaves, and slight differences of other elements. In addition, the ratio among the nutrition elements showed various values. Soil physical properties (especially the coarse sand and gravel content), soil bulk density, and soil porosity may be important factors affecting root growth and flower production of the rose. The site conditions where the Pingyin rose originated were compared to that where Bulgaria rose originated, so that the optimum conditions can be found for developing rose production.
