Bunge is an important medicinal herb, which is widely cultivated in most parts of China. It has attracted considerable attention because of its pharmacological properties and potential health benefits.
We used a field experiment to determine the effects of different genotypes and climatic factors on the performance (plant biomass, morphological parameters), active ingredients, rhizosphere soil physicochemical properties and microbial composition of at five cultivation locations.
The results showed that these parameters were significantly different in the six different genotypes of from five producing areas. Genotype and soil physicochemical properties were the main factors affecting the growth traits of , while genotype, climate and soil physicochemical properties were the main factors affecting the content of active components of . Microbial phospholipid fatty acid analysis showed that the biomass of Gram-positive and Gram-negative bacteria was affected by the genotypes of plants, while the biomass of arbuscular mycorrhizal fungi, fungi, Gram-positive and Gram-negative bacteria was affected by climate factors.
Based on the main results, DS993 was the most suitable genotype for in the five producing areas from the perspective of comprehensive growth traits and medicinal components, while DS993 and DS2000 were suitable for planting in Shandong province from the perspective of origin. DS996 is not suitable for all of the above production areas. These results are helpful to understand the ecological adaptability of different genotypes of resources, and to select appropriate S. miltiorrhiza genotypes for specific planting areas, so as to maximize yield and quality.
丹参是一种重要的药用植物，在中国大部分地区广泛种植。由于其药理特性和潜在的健康益处，它受到了相当多的关注。
我们采用田间试验，在五个种植地点测定不同基因型和气候因素对丹参的性能（植物生物量、形态参数）、活性成分、根际土壤理化性质和微生物组成的影响。
结果表明，来自五个产地的六种不同基因型丹参的这些参数存在显著差异。基因型和土壤理化性质是影响丹参生长性状的主要因素，而基因型、气候和土壤理化性质是影响丹参活性成分含量的主要因素。微生物磷脂脂肪酸分析表明，革兰氏阳性菌和革兰氏阴性菌的生物量受丹参植物基因型的影响，而丛枝菌根真菌、真菌、革兰氏阳性菌和革兰氏阴性菌的生物量受气候因素的影响。
基于主要结果，从综合生长性状和药用成分来看，DS993是五个产地中最适合丹参种植的基因型，而从产地角度来看，DS993和DS2000适合在山东省种植。DS996不适合上述所有产区。这些结果有助于了解不同基因型丹参资源的生态适应性，并为特定种植区域选择合适的丹参基因型，从而实现产量和质量的最大化。
