Effect of Intercropping of Angelica sinensis with Garlic on its Growth and Rhizosphere Microflora

Abstract

Aims and Methods A pot experiment was carried out to determine the effect of Angelica sinensis intercropped with garlic on A. sinensis growth and soil microbial communities in rhizosphere soil of A. sinensis under the scheme of A. sinensis intercropped with garlic. Results Soil microbial community was changed and bacteria functional group diversity was increased, and A. sinensis growth was improved when A. sinensis intercropped with garlic under the continuous cropping condition. Also, it shows that intercropping significantly increased root dry weight, and much less substantially shoot dry weight and plant height. Relative to the control, the activity of superoxide dismutase, peroxidase and catalase was increased by 80.00, 243.41 and 37.13%, respectively, but the content of malondialdehyde was decreased by 11.67%, along with a 70.13% yield improvement of A. sinensis, and 50.00% and 10.20% essential oil and alcohol-soluble extract increasing, respectively. The result also showed that the population of bacteria, aerobic cellulose-decomposing bacteria, organic phosphorus-solubilizing bacteria, inorganic phosphorus-solubilizing bacteria and potassium-solubilizing bacteria in rhizosphere soil were promoted in intercropping in vigorous growth stage. The abundance of aerobic cellulose-decomposing bacteria, organic phosphorussolubilizing bacteria and potassium-solubilizing bacteria in intercropping soils changed at the rootstock thickening. Although the total population of functional groups in intercropping A. sinensis rhizosphere soils was lower than in monocroping system, community diversity and evenness increased and dominance concentration decreased. Conclusions Intercropping A. sinensis with garlic can alleviate the soil sickness of A. sinensis.

Growth, Yield Components and Competitive Indices of Fennel and Fenugreek as Influenced by Intercropping System and Phosphorus Fertilizer Rate

“…This result was in consistent with the common assumption that in legume/non-legume intercropping systems, plants benefit from the direct transfer of fixed N 2 (Graham and Vance, 2000). These results are in harmony with those stated by (Abdelkader, 2012) on roselle when intercropped with guar, (Zhang et al, 2015) on Angelica sinensis when intercropped with garlic and (Abdelkader and Hassan, 2016) on dill when intercropped with fenugreek.…”

Influence of Chrysanthemum morifolium-maize intercropping pattern on yield, quality, soil condition, and rhizosphere soil microbial communities of C. morifolium

“…Due to differences in crop species ( Li and Wu, 2018 ) and root exudates ( Jiang et al., 2022 ), intercropping impacts soil microbial communities. Previous studies have identified that intercropping could alter soil microbial characteristics and microbial community compositions ( Sanguin et al., 2009 ; Bainard et al., 2012 ; Zhang et al., 2015 ). In our study, C. morifolium and maize rhizosphere soil bacterial and fungal networks in intercropping systems all exhibited higher average degrees and graph densities than monoculture, implying the interactions among microorganisms in intercropping systems were more active ( Figure 7 , Supplementary Tables 4, 5 ).…”

Evaluation The Effect of Intercropping Garlic with Grapevines on Productivity, Phytoremediation, Competitive Indices and Plant Parasitic Nematode Community تقييم تأثير تحميل الثوم مع العنب على الإنتاجية والمعالجة النباتية والعلاقات التنافسية ومجتمع النيماتودا المتطفلة على النبات

“…Intercropping significantly increased root dry weight, and much less substantially shoot dry weight and plant height (Zhang et al, 2015). Chinese leek possesses a high resistance to root knot nematodes, has strong nematicidal activity against M. incognita and can significantly reduce the incidence of disease caused by nematodes (Huang et al, 2016).…”
