紫草Lithospermum crythrorhizon Sieb.et Zucc.主要分布东北、山东、内蒙、河北、山西、河南等省区。随着临床用药的扩大,刨挖增加,使野生资源日渐枯竭,现在我省泰山、崂山等山区已很难觅见。我市博山区有少量分布,但早已不能提供商品。因此人工栽培就具有重要意义。近几年来,我站开始搞紫草的野生变家种研究。1985年种2亩,亩产138公斤。现将其栽培方法整理如下。一、生态习性紫草喜凉爽、湿润的气候条件,怕涝,怕高温,以地势高干燥、土层深厚、富含腐殖质、排水良好和渗水力强的中性或微酸性砂质壤土为
Lithospermum crythrorhizon Sieb.et Zucc. Mainly distributed in northeast, Shandong, Inner Mongolia, Hebei, Shanxi, Henan and other provinces. With the expansion of clinical medication, digging increased, the depletion of wild resources, and now Taishan, Laoshan and other mountainous areas have been hard to find. Boshan District, a small amount of distribution, but has long been unable to provide goods. Therefore, artificial cultivation is of great significance. In recent years, I began to engage in the wild change Lithospermum species research. In 1985 2 acres, 138 kg per mu. Now its cultivation methods are as follows. First, the ecological habits of Lithospermum hi cool, humid climatic conditions, fear of floods, afraid of high temperatures, high terrain dry, deep soil, rich in humus, well drained and seepage force of neutral or slightly acidic sandy loam
