Panax notoginseng is a prominent traditional Chinese medicinal herb, yet its yield and quality are significantly constrained by continuous cropping obstacles, primarily stemming from soil-related issues. This study analyzed soils subjected to various degrees of P. cultivation, without planting, natural forest floor soil planting. The objective was investigate variations in microbial communities, physicochemical properties, enzyme activities across different conditions. Macro-genome sequencing employed reveal shifts key factors influencing rhizosphere communities. Notably, the exhibited highest levels organic matter, carbon, total nitrogen, available potassium. Furthermore, showed pH, phosphorus, electrical conductivity, catalase, urease, acid phosphatase, sucrase, FDA hydrolase decreased after cropping, but increased again five years fallowing. Microbial analysis revealed that Bacteroidetes, Firmicutes, Chloroflexi dominated whereas Proteobacteria, Actinobacteria, Acidobacteria were predominant phyla soils. Continuous led an increase Acidobacteria, Gemmatimonadetes, Chloroflexi, while fallowing reduced Actinobacteria. Gemmatimonades almost exclusively present Overall, planting altered nutrients composition. Key communities included nitrate potassium, conductivity. suggests attention should be paid scientific rational fertilization practices mitigate effects cropping. Additionally, fallow period more than recommended. proper application probiotic fertilizers also advised. Finally, cultivating under conditions recommended as viable method.

The regulation of tobacco growth under preceding crop planting: insights from soil quality, microbial communities, and metabolic profiling

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Фев. 7, 2025

Specific microorganisms and metabolites in soil play key roles regulating organismal behavior. Currently, the effects of different preceding crops on rhizosphere quality flue-cured tobacco remain unclear. Four treatments were compared study: fallow + (CK), maize (T1), rapeseed (T2), wheat (T3). Results showed that significantly enhanced nutrient levels improved growth by altering microbial community structure. Previous cultivation promoted growth, diversity bacterial communities, notably decreased abundance urea-degrading bacteria. In contrast, crop reduced plant pathogenic fungi positive interactions. Metabolomics analysis altered lipids, organic acids, flavonoids, alkaloids, terpenoids, enhancing secondary metabolite synthesis pathways soil. Preceding regulated which potentially participated carbon nitrogen cycling, balancing nutrients, improving yield. Overall, three composition function structures soil, thereby increased concentration. Both boosted biomass. These findings offer new insights into potential interactions between communities strategies comprehensively growth.

Potato is an important crop that can be used both as grain and vegetable in northern China. However, the continuous cropping system of potato has led to a sharp decline its yield quality. As one effective strategies alleviate obstacle, rotation received extensive attention agricultural practices. On this basis, we have conducted in-depth exploration effects potato-maize on structure diversity soil microbial community, aiming analyze internal correlation mechanism between community quality crops. This study was based fields had been under monoculture for five years established six experimental treatments: potato-potato-potato (IR-A), potato-maize-potato (IR-B), potato-maize-maize (IR-C), (RF-A), (RF-B), (RF-C). The results showed IR planting model, IR-B significantly increased vitamin C content while reducing sugar compared IR-A (p < 0.05).

Crop rotation is a sophisticated agricultural practice that can modify the demographic structure and abundance of microorganisms in soil, stimulate growth proliferation beneficial microorganisms, inhibit development harmful microorganisms. The stability rhizosphere microbiome crucial for maintaining both soil ecosystem vitality crop prosperity. However, effects extended garlic‒maize on physicochemical characteristics garlic its remain unclear. To investigate this phenomenon, samples from were collected across four different lengths garlic–maize rotation. There notable positive associations between total nitrogen phosphorus contents duration Prolonged could increase maintenance α diversity. number years organic carbon (SOC) content emerged as principal determinants impacting evolution bacterial community structure, with SOC playing pivotal role sculpting species diversity within community. Additionally, remains predominant shaping root-associated community's β-nearest taxon index. these factors do not have effect fungal inhabiting rhizosphere. In comparison monoculture, amplify interconnectivity intricacy microbial ecological networks. Long-term further maintain networks interactions communities. It enlist plethora Bacillus to form biological barricade aids safeguarding against encroachment by pathogenic fungus Fusarium oxysporum, consequently diminishing disease incidence. This study provides theoretical foundation sustainable through long-term maize. Our research results indicate maintains stable microecology. compelling evidence microbiota stability, emphasizing importance cultivating specific enhance strategies farming, thereby promoting sustainability agriculture.
