微生物菌剂与根瘤菌对大豆生长发育、土壤理化性质和细菌群落的影响
Effects of Microbial Agent and Rhizobia on Soybean Growth and Development,Soil Physicochemical Properties and Bacterial Communities
摘要
Abstract
To clarify the effects of different rhizobium inoculants and microbial agents on soybeans and soil,and to identify suitable combinations for rhizobium and inoculant application.From May to September 2024,experiments were conducted at Plot 16 of the Seventh Division Agricultural Science Research Institute.The Henong 71 soybean variety was used as the experimental material.The conventional fertilization treatment(urea 540 kg/hm2+potassium sulfate 300 kg/hm2+superphosphate 420 kg/hm2)served as the control(T1).Five additional fertilization treatments were established based on this control,which wereT2(conventional fertilization+ARC microbial agents),T3(conventional fertilization+R59),T4(conventional fertilization+R17),T5(conventional fertilization+ARC+R59),and T6(conventional fertilization+ARC+R17).Growth characteristics,yield,and soil physicochemical properties of soybean plants under different treatments were compared.Compared with other treatments,the T6 composite inoculation treatment yielded the most favorable soybean agronomic traits,root nodulation capacity,and yield performance.Additionally,it increased soil organic matter while significantly reducing pH,electrical conductivity,and water-soluble salt ions.Individual inoculation with R17 or ARC both promoted soybean yield,increasing it by 8.61%and 6.50%,respectively,compared to the control.In contrast,individual inoculation with R59 had only a marginal positive effect on soybean growth and yield,showing no significant difference from the conventional fertilization treatment.During the trifoliate stage and maturity stage,the dominant bacterial phyla in soils across all treatments were Proteobacteria,Gemmatimonadota,Acidobacteria,and Actinobacteriota.At maturity stage,the abundance of Proteobacteria and Acidobacteria increased,but the composition of the core microbial community remained unchanged.Electrical conductivity showed a highly significant positive correlation with water-soluble salts.At the trifoliate stage,water-soluble salts and electrical conductivity exhibited significant positive correlations with calcium,magnesium,potassium,and sodium ions.At maturity stage,significant positive correlations were observed with sulfate ions,magnesium ions,and potassium ions.This indicates that soil ions undergo dynamic changes throughout the growth stages.Comprehensive analysis indicates that the combined application of ARC+R17 yields the most favorable effects on soybean growth and development,yield,soil physicochemical properties,and bacterial community improvement.This approach is recommended for promotion and application in soybean production.关键词
