Aims

We aimed to explore the effects of Fallopia multiflora–Andrographis paniculata intercropping model on yield, quality, soil nutrition and rhizosphere microorganisms of F. multiflora, an important raw material of a traditional Chinese medicine. The data will provide empirical evidence for the application and promotion of the system in agricultural production.

Methods

F. multiflora’s yield, potential medicinal quality, and rhizosphere soil nutrient contents, pH, enzyme activities, and microbial characteristics (such as diversity and structure of the bacterial community) were compared between the intercropped system and a monoculture of F. multiflora.

Results

Compared with the monoculture of F. multiflora, F. multiflora–A. paniculata intercropping significantly increased the stem diameter, root fresh weight, yield and stilbene glycoside content of F. multiflora. The activities of urease and sucrase and the amounts of bacteria and actinomycetes in rhizosphere soil of intercropped F. multiflora were significantly higher than those in rhizosphere soil of the monoculture. Intercropping increased the diversity of rhizosphere bacteria and the relative abundances of potentially beneficial microorganisms. Correlation analysis shows that the yield and quality of F. multiflora were closely related to urease and invertase activities, alkaline hydrolysis nitrogen content, soil organic matter content, bacterial biomass, and pH. The results of principal component analysis show that the score of intercropping soil was higher than that of monoculture soil.

Conclusions

A. paniculata intercropping has a significant impact on the rhizosphere soil of F. multiflora, and can improve the yield and quality of F. multiflora by improving the rhizosphere soil ecological environment and soil quality.

多花输卵管-穿心莲间作模式对多花的产量、品质、土壤营养及根际微生物的影响

宗旨

【摘要】：目的探讨多花输卵管-穿心莲间作模式对中药重要原料多花的产量、品质、土壤营养及根际微生物的影响。该数据将为该系统在农业生产中的应用和推广提供经验依据。

方法

F.野蔷薇的产量，潜在药用质量，和根际土壤养分含量，pH值，酶活性和微生物特性（如多样性和细菌群落的结构）中的间作系统和的单作之间相比F.野蔷薇。

结果

用的单作比较F.野蔷薇，F.野蔷薇-穿心莲显著间作增加的茎直径，根鲜重，产量和二苯乙烯苷含量F.野蔷薇。间作多花根际土壤脲酶和蔗糖酶活性以及细菌和放线菌数量均显着高于单作根际土壤。间作增加了根际细菌的多样性和潜在有益微生物的相对丰度。相关性分析表明，杂草产量和品质与尿素酶和转化酶活性、碱性水解氮含量、土壤有机质含量、细菌生物量和 pH 值密切相关。主成分分析结果表明，间作土壤得分高于单作土壤。

结论

穿心莲间作对根际土壤显著影响F.野蔷薇，并能提高产量和质量F.野蔷薇通过改善根际土壤生态环境和土壤质量。
