Intercropping With Turmeric or Ginger Reduce the Continuous Cropping Obstacles That Affect Pogostemon cablin...

Area of Science:

• Agricultural Science
• Soil Microbiology
• Plant Science

Background:

• Continuous cropping of patchouli degrades soil properties and microbial environments.
• This degradation reduces the chemical content of medicinal plants, impacting cultivation.
• Addressing these issues is crucial for the sustainable development of the patchouli industry.

Purpose of the Study:

• To investigate the effects of intercropping patchouli with turmeric or ginger on soil microbial communities.
• To analyze the impact of intercropping on soil physical and chemical properties.
• To determine if intercropping can mitigate the negative effects of continuous cropping on patchouli.

Main Methods:

• High-throughput sequencing to analyze soil bacteria and fungi communities.
• Redundancy analysis (RDA) to study interactions between soil factors and microbes.
• Assessment of soil physical, chemical properties, and enzyme activities.

Main Results:

• Intercropping significantly improved soil microbial abundance, diversity, and community structure.
• Turmeric and ginger intercropping enhanced dominant bacteria, soil metabolism, and enzyme activities.
• Soil physical and chemical properties, including pH and Ca, were favorably modified.

Conclusions:

• Intercropping patchouli with turmeric and ginger effectively ameliorates continuous cropping problems.
• This practice positively influences soil microbial distribution and enhances active ingredient content in patchouli.
• Intercropping offers a sustainable solution for improving medicinal plant cultivation.
