Published: Feb. 29, 2024

Using traditional Chinese medicine residues as raw materials, different biochars (BC) were prepared through oxygen-limited pyrolysis at 300 °C, 500 and 700 BC was ball-milled to produce biochar (BMC). these adsorbents adsorb the allelopathic autotoxic substance quercetin. The physical chemical properties of various derived from characterized using Brunauer–Emmett–Teller-N2 surface areas (BET), scanning electron microscopy (SEM), Fourier transform IR spectroscopy (FTIR), X-ray diffraction (XRD), Raman (Raman). study investigated effects initial pH value, humic acid concentrations, multiple adsorption–desorption experiments on removal quercetin solution. article discusses adsorption mechanism in solution by a residue, based results kinetics isotherm fitting. findings indicate that increasing temperature reduces oxygen-containing functional groups BC, enhances aromaticity, stabilizes carbon structure. pore structure BMC becomes more complex after ball milling, which increases number surface. Among samples tested, BMC700 exhibits best performance, with an capacity 293.3 mg·g–1 318 K. process follows pseudo-second-order kinetic model Freundlich model. is primarily form multimolecular layer adsorption. Its involves pore-filling effect, hydrogen-bonding interaction, electrostatic π–π coexistence, well yoke effect. Additionally, they are highly recyclable show promise addressing continuous cropping issues.

Abatement effects of different soil amendments on continuous cropping of Codonopsis pilosula

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: April 19, 2024

Introduction Codonopsis pilosula is widely sought-after in China as a substitute for the more expensive ginseng. Continuous cropping of C. supports vibrant health-supplement industry but requires significant inputs fertilizers which increase production costs and degrade environment. Methods Here, three environmentally-friendly natural fertilizers, including biochar, bacterial fertilizer, vermicompost, were used at different concentrations (undiluted, diluted 10 times, 50 times) to determine their efficacy seed germination growth physiology continuous cropping. Results The results showed that vermicompost with leachate could all rate, potential index seeds treated inter-root soil ; activity antioxidant enzymes (superoxide dismutase peroxidase) seedlings under stress , reduce over-accumulation malondialdehyde (MDA) content, resistance seedlings. After transplanting, superoxide (SOD) increased by an average 16.1%. Peroxidase (POD) levels 16.4%. Additionally, there was reduction MDA decrease 50%, content osmotic-regulating substances (free proline soluble protein content) exhibited increase. Discussion In conclusion, manure, have overcome challenges extensive fertilizer use .

Published: Dec. 31, 2023

Legumes have important nutritional and economic values, but their production faces continuous cropping obstacles that seriously affect yield formation. In order to reduce the negative impact of legumes, it is necessary understand response mechanisms legumes cropping, causes measures alleviate obstacles. This review aimed identify current knowledge gap in field provide direction focus for future research. The start with soil degradation, leading oxidative stress plants. triggers expression plant-hormone- signal-molecule-related genes, activating defense system causing Although there has been progress researching these challenges legume crops, many questions remain. We believe exploration molecular crops responding rhizosphere signal exchange environment repair after long-term soybean, excavation candidate genes functional loci related are breakthroughs proposing effective obstacle management strategies future.

Continuous cropping of Patchouli alters soil physiochemical properties and rhizosphere microecology revealed by metagenomic sequencing

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 13, 2025

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.
