白茨生物学特性

白茨: 属蒺藜科, 白茨属, 是我国古老的乡土沙生植物种。在内蒙古自治区有四种: 1.小果白茨 2.白茨 3.大白茨 4.球果白茨 白茨在亚州中部旱生区系中, 它是古老的第三纪残遗种。是沙漠、半沙漠区域建群植物种之一。是优良的并具有较高经济价值的固沙植物。经研究: 白茨具有较强的耐旱性, 耐热性, 耐瘠薄, 耐沙漠、抗风蚀的特性。在脆弱的生态环境中, 积极保护天然野生的自然资源, 大量培育和发展白茨对固定流沙, 资源开发与利用将起到重要作用。

Biological Characeristics of Nitraria

Nitraria is one of ancient native species living in desert areas. There are four species of it in Inner Mon golia region. 1. Nitraria sibirica pall 2. Nitraria tangutorum Bobr 3. Nitraria roborowskii Kom 4. Nitraria sphaerocarpa Maxim In dry areas of central Asia, Nitraria is the relic species in the ancient Tertiary period and one of the mass plants in desert and semi-desert zones. It is the better plant to fix shifting sands with higher economic vaulue, It has been studied that Nitraria has better characters for resisting drought, high temperature, poor soil, strong winds and being covered by sands. In the fragile ecological envovmment, to pretect and breed natural wild plants, such as Nitraria, will play an important role in fixing shifting sands, exploring and utilizing natural resources.
