摘要：

青海省地道中药材“西宁大黄”野生资源濒临枯竭,人工种植规模不断扩大.定期采集青海省大黑沟2年生种植大黄,分析测试其矿物质元素,为西宁大黄资源的可持续开发和利用提供科学依据.研究表明:大黑沟种植大黄的根、茎、叶等不同的组织器官,以及在不同生长季节对矿物质元素营养的需求具有动态性变化的特征.

关键词: 种植大黄, 矿物质元素, 大黑沟

Abstract:

Rheum is called “Xining Dahuang”, which are traditional medicinal materials of local Qinghai.Natural resources are nearly exhausted.Recently, scale of planting is becoming larger and larger.We picked the cultivated Rheum sp.of two-year period in Daheigou of Qinghai Province, and analyzed the content of mineral elements.The results showed that mineral elements accumulation in the root, stem and leaf of cultivated Rheum is different from each other and the needing of mineral elements during different seasons of growing has a dynamic characteristic.We want to provide the scientific evidence for sustainable development and reasonable utilization of Rheum sp.resources

Key words: Rheum, mineral elements, Daheigou
