宁夏人工种植银柴胡不同区域适应性研究

Investigation to the adaptability of Stellaria dichotoma L.var.lanceolata Bge.planted in different areas in Nningxia

银柴胡主要分布在宁夏、内蒙古、陕西3省毗邻的干旱少雨沙生草原区,极耐干旱,主要伴生植物为耐旱的草本植物或小灌木,野生银柴胡生长区的土壤类型为淡灰钙土.还调查了银柴胡的生物学、生态学特性及宁夏主要种植区银柴胡的生长状况,结果表明,人工种植银柴胡的最佳地区是宁夏中部干旱带的沙生草原区.

The Stellaria dichotoma L. vat. lanceolata Bge. mainly distributes in the drought and sandy grassland areas in Ningxia, such of Inner Mongoulie, and the north area of Shanxi province, bearing the drought extremely, mainly accompanied with the herb plants resistant to the drought or the small bush, the soil type where the wild Stellaria dichotoma L. var. lanceolata Bge. grows is the pale serosem. Besides, this article also investigated biology, the ecology characteristic of the Stellaria dichotoma L. var. lanceolata Bge. and its growth condition in Ningxia main planting areas, and made the conclusion that the best manual growth area of Stellaria dichotorna L. vat. lanceolata Bge. is the sandy grassland areas in the middle arid zone of Ningxia.
