为了确定何首乌、桔梗、苍术、射干4种中药材在种植过程中最适的土壤酸碱度(pH值),通过盆栽试验,研究药材在不同pH值土壤中的长势及产量情况。结果表明:4种中药材在pH值为4.5~8.5的土壤中均能生长,但长势和产量表现出一定的差异。何首乌、苍术、桔梗和射干的最适生长pH值分别为6.0、6.0、7.0和7.5,适宜生长的pH值范围分别为5.5~6.5、6.0~7.0、6.0~7.0和6.0~8.0。
In order to determine the optimum soil pH (pH value) of four Chinese medicinal materials of Polygonum multiflorum, Campanulaceae, Cangzhu and Shegan, pot experiments were conducted to study the growth and yield of herbs in different pH soils. The results showed that four kinds of Chinese herbal medicines could grow in the soil with pH 4.5 ~ 8.5, but their growth and yield showed some differences. The optimum growth pH value of Polygonum multiflorum, Artemisia selengensis, Platycodonis, and Pericarp were 6.0, 6.0, 7.0 and 7.5, respectively. The optimal pH range for growth was 5.5-6.5, 6.0-7.0, 6.0-7.0 and 6.0-8.0 respectively.
