Effects of Microbial Inoculants and Biochar on Soil Physicochemical Properties and Car-bon Sequestration Capacity of Plants
以"绿萝"为试材,设置4个处理,即CK(对照,未添加菌剂和生物炭)、A(添加生物炭)、B(接种微生物菌剂)、AB(微生物菌剂+生物炭),研究微生物菌剂协同生物炭处理对土壤理化性质、植物光合特性以及生物量的影响,进而明确微生物菌剂与生物炭协同作用对土壤改良以及植物固碳能力的影响效果.研究结果表明:土壤中添加微生物菌剂和生物炭能有效提高土壤肥力以及植株生物量.与CK相比,A、B、AB处理土壤孔隙度分别提高11.83%、8.13%、12.80%;有机碳分别提高8.73%、14.71%、19.24%;铵态氮含量分别提高7.77%、17.96%、29.36%;速效磷含量分别提高11.80%、14.07%、18.69%;速效钾含量分别提高6.26%、6.86%、9.90%;蔗糖酶活性分别提高5.77%、36.54%、63.46%;脲酶活性分别提高84.12%、206.43%、266.52%;过氧化氢酶10.46%、119.77%、144.18%;植株固碳量分别提高14.28%、28.57%、46.43%;植物生物量分别提高12.25%、22.90%、27.17%.综上,微生物菌剂协同生物炭处理能有效改良土壤并促进植物固碳能力的提升,本研究结果将为城市垂直绿化碳汇管理提供技术支持.
This study ultilized"scindapsus aureus"as the experimental material and set up four treatments,namely CK(control,no bacterial agent and biochar added),A(biochar added),B(inoculate with microbial inoculant),and AB(Microbial agent+bio-char),to study the effects of microbial inoculants and biochar treatments on soil physicochemical properties,plant photosynthetic characteristics,and biomass,thereby clarifying the effects of the synergistic effect between microbial inoculants and biochar on soil improvement and plants carbon sequestration capacity.The results showed that the addition of microbial inoculants and biochar to soil enhanced the soil fertility and plant biomass.Compared to the control,total soil porosity increased by 11.83%,8.13%,and 12.80%for treatments A,B,and AB,respectively.Organic carbon levels rose by 8.73%,14.71%and 19.24%respectively,while the content of ammonium nitrogen increased by 7.77%,17.96%,29.36%respectively.The content of available phosphorus content rose by 11.80%,14.07%and 18.69%respectively and the content of available potassium increased by 6.26%,6.86%and 9.90%respectively.Additionally,the sucrase activity increased by 5.77%,36.54%and 63.46%respectively,the urease activity increased by 84.12%,206.43%and 266.52%respectively,and the catalase activity increased by 10.46%,119.77%and 144.18%respectively.The plant carbon sequestration increased by14.28%,28.57%and 46.43%respectively while the plant bio-mass increased by 12.25%,22.90%and 27.17%respectively.In conclusion,the microbial inoculants and biochar treatments could effectively improve the soil and promote the carbon sequestration ability of plants.This study would provide technical supports for the management of carbon sinks in urban vertical greening.
