Took the Salvia miltiorrhiza planting in Zhengning area as the research object, five gradient density treatments were set up to systematically analyze the effects of planting density on the growth dynamics, yield composition and medicinal component accumulation of Salvia miltiorrhiza. The results showed that the medium-density treatment had the best overall benefits, and its key growth indicators such as plant height and stem diameter during the seedling stage and flowering stage were significantly better than those of other treatments. In conclusion, 125 000 plants/hm2 was the ideal planting density for high-quality and high-yield production of local Salvia miltiorrhiza, which could provide technical references for standardized cultivation.

以甘肃庆阳正宁地区的丹参为对象,设置5个梯度密度处理,系统分析了种植密度对丹参生长动态、产量构成及药用成分积累的影响。结果显示:中密度(T3, 125 000株/hm2)的综合效益最优,其苗期与花期的株高、茎粗等关键生长指标显著优于其他处理;收获期鲜、干产量分别达5 608.94 kg/hm2和1 661.18 kg/hm2,商品率高达89.13%,核心药用成分丹参酮ⅡA与丹酚酸B质量分数分别达0.45%和8.67%;高密度处理(T4、T5)易导致植株长势衰弱、品质降低;低密度处理(T1)则因土地资源利用率不足造成总产偏低。综上,125 000株/hm2是当地丹参优质高产的理想种植密度。研究结果可为规范化栽培提供技术参考。

以甘肃庆阳正宁地区的丹参为对象,设置5个梯度密度处理,系统分析了种植密度对丹参生长动态、产量构成及药用成分积累的影响。结果显示:中密度(T3, 125 000株/hm2)的综合效益最优,其苗期与花期的株高、茎粗等关键生长指标显著优于其他处理;收获期鲜、干产量分别达5 608.94 kg/hm2和1 661.18 kg/hm2,商品率高达89.13%,核心药用成分丹参酮ⅡA与丹酚酸B质量分数分别达0.45%和8.67%;高密度处理(T4、T5)易导致植株长势衰弱、品质降低;低密度处理(T1)则因土地资源利用率不足造成总产偏低。综上,125 000株/hm2是当地丹参优质高产的理想种植密度。研究结果可为规范化栽培提供技术参考。

Took the Salvia miltiorrhiza planting in Zhengning area as the research object, five gradient density treatments were set up to systematically analyze the effects of planting density on the growth dynamics, yield composition and medicinal component accumulation of Salvia miltiorrhiza. The results showed that the medium-density treatment had the best overall benefits, and its key growth indicators such as plant height and stem diameter during the seedling stage and flowering stage were significantly better than those of other treatments. In conclusion, 125 000 plants/hm2 was the ideal planting density for high-quality and high-yield production of local Salvia miltiorrhiza, which could provide technical references for standardized cultivation.
