近年来土壤酸化严重,而云南省文山三七在酸性土壤环境产量不高,甚至酸性强的土壤环境难以生长。“特贝钙”牌土壤调理剂是采用海洋牡蛎壳经保护性焙烧工艺生产的缓释型含钙土壤改良剂,纯物理加工,具有中和土壤酸度、增加土壤有效钙,降低重金属危害、改良土壤理化结构等功能。通过设置小区试验,分析“特贝钙”土壤调理剂对三七产量和 In recent years, soil acidification is serious, and Yunnan Wenshan notoginseng acid soil environment yield is not high, and even acidic soil environment difficult to grow. “Te Bei calcium ” brand soil conditioner is the use of marine oyster shell by the protective roasting process of slow-release calcium soil improver, purely physical processing, with the acidity of the soil, increase soil available calcium, reduce heavy metal hazard , Improve soil physical and chemical structure and other functions. By setting up a plot test, we analyzed the yield and yield of soil in Panax notoginseng
