“…We found that the soil pH under different concentration Cd treatments did vary significantly for using the GPE Jiaosu and Jiaosu residue. Meanwhile, the application of GPE Jiaosu and Jiaosu residue modified the basic soil property, including the contents of SOC, TN, AN, and TP, when exposed to different levels of Cd stresses, which was similar to the effect of biochar and compost on soil fertility (Brown et al 2023;Huo et al 2023).…”

Cadmium (Cd) pollution poses a serious threat to various ecosystems, and phytoremediation is an alternate method for developing the soil health. To better utilize phytoremediation for Cd‐contaminated soil remediation, the ginkgo leaves, pine needles, and Eucommia bark were mixed and naturally fermented to obtain Ginkgo biloba–Pinus massoniana–Eucommia ulmoides (GPE) Jiaosu and Jiaosu residue, whose effects on Broussonetia papyrifera planted in Cd‐contaminated soil were evaluated. The results showed that the contents of the protein, phenolic, vitamin E, and alcohol of GPE Jiaosu were 4400 ± 0.46, 0.22 ± 0.01, 0.88 ± 0.24, and 4.63 ± 0.25 μL/mL, accordingly, with fine antioxidant activity. The soil pH, electrical conductivity content, organic carbon, total nitrogen, total phosphorus, alkali‐hydrolyzable nitrogen, available phosphorus, and Cd concentration were all significantly (p < 0.05) modified. The chlorophyll content of B. papyrifera was increased by using Jiaosu residue in 12 hours, while the promotion effect of Jiaosu appeared in the later stage (60 days). The Cd tolerance physiological indexes such as malondialdehyde content and antioxidant enzymes' activity were all regulated. Applying the Jiaosu residue, the Cd in stems was decreased by 72.61% under 1000 mg/kg Cd treatment. These results suggested that GPE Jiaosu and Jiaosu residue can improve the properties of Cd‐contaminated soil, promote the Cd tolerance of B. papyrifera, and affect the Cd migration. The current study provides a new bioremediation method using the Jiaosu and Jiaosu residue as Cd environmental remediation materials in a recyclable pathway, which is a circular and healthy development concept that integrates economic, ecological, and social significance.

Objective: We used microbiology and molecular biology techniques to screen out high temperature and low temperature resistant saprobiotics for compost and prepared a compound fermentation bacteria agent to rapidly ferment cattle manure into high-quality organic fertilizer in low temperature season.Methods: Conventional composting and high-throughput techniques were used to analyze the changes of physical and chemical indexes and biodiversity in the process of composting, from which high and low temperature resistant strains were obtained, and high temperature and low temperature resistant solid composite bactericides were prepared and added to composting to verify the effects of composite bactericides on composting.Results: The conventional composting cycle took 22 days, and the diversity of micro ora increased rst and then decreased. Composting temperature and microbial population were the key factors for the success or failure of composting. Two strains of high temperature tolerant bacteria and 6 strains of low temperature resistant bacteria were screened out and they were e cient in degrading starch, cellulose and protein. The high temperature and low temperature resistant solid bacterial agent were successfully prepared with adjuvant. The preparation could make the compost temperature rise quickly at low temperature, the high temperature lasted for a long time, the water content, C/N and organic matter fell quickly, and the contents of total phosphorus and total potassium were increased, and the seed germination index was signi cantly improved. Improve the composting effect. Conclusion:The solid composite bacterial agent can shorten the composting time at low temperature, and improve the composting e ciency and quality.
