Pogostemon cablin (Patchouli), an essential medicinal plant in the Lamiaceae family, faces significant challenges under continuous cropping (CC) obstacles. This study examined rhizospheric soil bacterial communities of patchouli four different CC years, zero (CK), one (T1), two (T2), and three (T3) years through high-throughput 16S rRNA gene amplicon sequencing. Results showed long-term led to properties enzyme activity shifts. Key parameters such as pH total potassium (TK) decreased, while ammonium nitrogen (NH4+–N), organic carbon (SOC), nitrate (NO3−–N), available (AK), phosphorus (AP), (TN), (TP) increased over years. Enzyme activities, including ß-glucosidase (ß-GC), polyphenol oxidase (PPO), catalase (CAT), N-acetyl-β-D-glucosaminidase (NAG), leucine aminopeptidase (LAP), were notably affected. The altered community structure composition, reducing relative abundance Proteobacteria, Firmicutes, Actinobacteria, Planctomycetota time.

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.

In grape cultivation, incorrect water regulation will lead to significant wastage, which in turn change soil structure and disrupt nutrient cycling processes. This study aimed investigate the effects of different treatments [by setting moderate stress (W1), mild (W2), adequate availability (CK)] on physical-chemical properties enzyme activity greenhouse during growing season. The result showed that W2 treatment had a negative impact build-up dissolved organic carbon (DOC), nitrate nitrogen (NO3-N), available phosphorus (AP). Throughout reproductive period, W1 decreased soil's microbial biomass (MBC) (MBN) contents, MBC was more vulnerable stress. During growth trends urease, catalase, sucrase activities depth were ranked as 10-20 cm > 0-10 20-40 cm. urease suppressed by both treatments, while invertase various layers under differed substantially. also reduced catalase layer These findings suggested can conserve enhance ecology soils. Therefore, most effective measure for local cultivation.

Continuous cropping (CC) profoundly impacts soil ecosystems, including changes in factors and the structure stability of microbial communities. These are interrelated together affect health plant growth. In this research, metagenomic sequencing was used to explore effects CC on physicochemical properties, enzyme activities, community composition, functional genes rhizosphere patchouli. We found that can lead various factors, continuous reduction pH NH4+ -N unstable many factors. addition, S-PPO activity increased significantly with years, but S-NAG first 2 years decreased third year. Metagenomic results showed changed diversity composition The relative abundance Pseudomonas Bacteroides substantially from phylum level. At genus level, number genera specific zero-year (CK) (T1), second (T2), (T3) significantly, 1798, 172, 42, 44, respectively. changed, among which COG0823, a gene cellular process signaling functions, after CC. id="M2">NH4+ -N, S-CAT, S-LAP, SOC were main environmental affecting rhizosphere-dominant communities at while pH, SOC, AK key Pogostemon cablin . summary, study dynamic microorganisms during CC, providing theoretical basis for understanding formation mechanism prevention obstacles contributing formulation scientific management fertilization strategies.

Long-term continuous cropping of tobacco causes dysbiosis soil microbial communities, the imbalance nutrients, and increase pathogenic bacteria, which will slow growth development plants, reduce production quality, cause significant losses to farmers. The application Potassium fulvic acid can not only provide but also inhibit propagation pathogens in along with raising amount organic matter soil, is an effective way improve health. In this experiment, Tobacco variety SNT60 was used as test material, 6 treatments were set up by pot test, they were: no fertilisation control group (CK), special fertiliser (NPK), 3.45 g/kg potassium (T1), 4.65 (T2), 5.85 (T3), 7.05 (T4), Ten replications for each treatment mixed potted before transplanting, 70% basal 30% supplementary fertiliser.
