Comparative Analysis of Biodegradable Mulches on Soil Bacterial Community and Pepper Cultivation

Agronomy, Год журнала: 2024, Номер 14(5), С. 905 - 905

Biodegradable mulch films (BMFs) are becoming increasingly popular in agricultural practices. However, research on the ecological impact of biodegradable pepper–soil systems is still scarce. To compare differential effects BMFs and polyethylene (PE) soil chemical properties, bacterial community composition, pepper cultivation, a study was conducted encompassing eight distinct treatments. These treatments included three varieties polybutylene adipate terephthalate (PBAT) combined with polylactic acid (PLA) mulches: PP-JL, PP-SD, PP-SH; black polypropylene carbonate (PPC-BK); brown PPC (PPC-BR); mulch; straw mulching (NCK); an uncovered control (PCK). After applying mulches for 129 days, most PBAT + PLA had reached rupture phase, whereas PE film induction phase. Pepper yield obviously higher all mulched (4830 kg hm−1) than un-mulched (3290 hm−1), especially BMF PP-JL treatment, which showed notable improvements yield. Although maintained lower temperature mulch, they were control. Furthermore, composition network not markedly affected by different conditions. PP-SH treatment significantly increased abundance Pseudomonas, Nitrosomonas, Streptomyces genera. Moreover, Lactobacillus Gp16 substantially more abundant PPC-black (BK) PPC-brown (BR) compared to treatment. This could provide valuable insights into benefits cultivation. as our experiments only one season, it imperative undertake long-term across consecutive seasons years thorough understanding comprehensive study.

There is a growing problem in China, whereby tomato replant disease being affected by Fusarium spp., Meloidogyne and Phytophthora spp. To address these pests that live the soil, we evaluated how well applying dazomet (DZ) 1,3-dichloropropene (1,3-D) combination directly to soil works three different trials. The combined treatment of DZ + 1,3-D (25 10 g a.i. m⁻²), applied at 50% reduction rate, effectively decreased populations more than 94%. This resulted low root galling indices 2.67%, 4.17%, 10.83% In addition, it significantly number colonies 82%, resulting 3.33%, 10.00%, 10.42%, respectively. also greatly increased yield profit for growers. results obtained with alone methyl bromide (MB) 50 m⁻² were similar. However, better those 20 controlling soilborne fungi trials I III. Compared untreated controls solarization disinfestation treatments, all chemical treatments performed better. Due its effectiveness economic advantages, fumigation m⁻²) recommended pest management programs cultivation China. highly effective managing reside soil.

Metagenomic Insights into the Enhancement of Bioavailable Nitrogen in Continuous Cropping Soil Through the Application of Traditional Chinese Medicine Residue Following Fumigation

Genes, Год журнала: 2024, Номер 15(12), С. 1532 - 1532

Опубликована: Ноя. 28, 2024

Background/Objectives: Chemical fumigation can effectively inhibit the occurrence of soil-borne diseases; however, this approach negatively affect structure soil microbial community. The combination fumigant and organic fertilizer application thus represents a widely adopted strategy in agricultural practice. Traditional Chinese medicine residue (TCMR) is high-quality fertilizer; impact post-fumigation TCMR on keystone taxa their functional traits remains uncertain. Methods: This study examined effects five fertilization treatments diversity, key species, related genes communities rhizosphere continuous cropping pepper. Results: followed by markedly enhanced nutrient content significantly influenced community composition as well gene patterns associated with nitrogen cycling. It was also strongly correlated bioavailable content. abundance bacterial species (Pseudomonadota, Actinomycetota, Bacillota) substantially increased following application, alongside notable rise Ascomycota within fungal shift contributed to an increase beneficial while reducing that harmful bacteria. Additionally, addition affected denitrification DNRA involved cycling; specifically, nirB nirK were Conclusions: combined chemical fumigants modified influencing TN other nutrients, these alterations linked multiple nitrogen-cycling genes.
