摘要:

为评估微生物菌剂对土壤微生物数量和理化性质的影响,以北京市平谷区田间桃和盆栽桃为研究材料,探讨了微生物菌剂贝莱斯芽孢杆菌BPC6(B)、利迪链霉菌(S)及其复配菌剂(BS)对土壤微生物和理化特性的影响。研究结果表明,施用菌剂B、BS和S均能显著影响田间土壤的微生物数量,有效提升细菌、真菌和放线菌丰度。此外,添加微生物菌剂还能提高田间土壤养分的利用效率,提高土壤有机质、总碳、总氮、碱解氮、硝态氮、铵态氮、速效钾、总磷和有效磷的含量,而对总钾含量未产生显著影响。其中,施用菌剂B、BS和S后对桃收获期土壤营养指标的影响为:较对照组,土壤碱解氮含量分别显著提高11.89%,15.19%和35.27%,速效钾含量分别显著提高35.58%,22.92%和41.75%,有效磷含量分别显著提升37.97%,3.65%和62.60%。相关性分析结果表明,土壤微生物数量受多种环境因子调控,其与速效钾含量呈显著正相关关系,表明速效钾可能是驱动土壤微生物数量变化的关键因子之一。田间试验结果表明,微生物菌剂S提高土壤肥力效果最显著,复配菌剂BS次之,而菌剂B效果相对较弱。盆栽试验进一步表明,微生物菌剂在提高土壤碱解氮水平方面有重要作用。较对照组,菌剂B、BS和S使盆栽桃中蟠100号土壤碱解氮含量分别显著提高15.65%,16.67%和13.45%;菌剂BS和S引起中桃14号土壤有效氮含量分别显著提升13.65%和18.13%。综合分析表明,微生物菌剂能够增加土壤微生物数量、提升土壤肥力,为桃绿色生产提供科学支持和实践参考。

Abstract:

To evaluate the effects of microbial inoculants on soil microbial population and physicochemical properties,this study investigated the effects of the microbial inoculants,including Bacillus velezensis BPC6(B), Streptomyces lydicus (S), and their combined inoculants(BS) on the soil microbial abundance and physicochemical properties of field-grown and potted peach trees in Pinggu District,Beijing.The results showed that applying microbial inoculants(B,BS,and S) significantly increased the abundance of bacteria,fungi,and actinomycetes in field soils.Additionally,the microbial inoculants enhanced soil nutrient utilization efficiency by increasing the contents of soil organic matter,total carbon,total nitrogen,available nitrogen(alkaline-hydrolysis nitrogen),nitrate nitrogen,ammonium nitrogen,available potassium,total phosphorus,and available phosphorus,while no significant effect was observed on total potassium.Among them,during the peach harvest period,application of microbial inoculants B,BS,and S significantly increased soil available nitrogen by 11.89%,15.19%,and 35.27%,respectively,compared to the control.Available potassium increased significantly by 35.58%,22.92%,and 41.75%,respectively,while available phosphorus rose significantly by 37.97%,3.65%,and 62.60%,respectively.Correlation analysis further revealed that soil microbial abundance was significantly influenced by multiple soil environmental factors,particularly showing a strong positive correlation with available potassium content.The effect of improving soil fertility with different microbial inoculants(B,BS,and S) was as follows:microbial inoculant S was the most effective,and the combination application of B and S was better than that of individual application of inoculant B.The pot experiment further confirmed the important role of microbial inoculants in increasing soil available nitrogen levels.Compared to the control,application of microbial agents B,BS,and S significantly increased soil available nitrogen in potted peach Zhongpan 100 by 15.65%,16.67% and 13.45%,respectively;while microbial agents BS and S significantly increased available nitrogen in Zhongtao 14 by 13.65% and 18.13%,respectively.Overall,microbial inoculants effectively improved soil microbial abundance and fertility,providing scientific support and practical references for sustainable peach production.
