土壤是重要的碳储存库,增加农业土壤有机碳储量是缓解大气CO_(2)浓度增加和应对全球气候变化的有效手段.该文以中国西北地区、华北地区和华东地区的蚕豆种植区域为研究对象,结合气候、土壤性质等影响因素,探究在区域尺度下表层土壤有机碳储量差异及其环境因子的影响机制.研究结果表明:研究区土壤有机碳储量共同受到气候因子、生物因子和化学因子的综合作用,其中气候因子和化学因子的交互作用对碳储量的影响最显著.在气候因子中经度、纬度、海拔对蚕豆产区土壤有机碳储量影响较为显著,体现在3个蚕豆产区的土壤有机碳储量中贡献最大的环境因子是纬度,且土壤有机碳储量呈现随经度的增加而减少,随海拔的增高而增高的趋势.在化学因子中DOC、TN、pH值对蚕豆产区土壤有机碳储量影响较为显著,在生物因子中影响较为显著的是土壤q_(CO_(2)).分区域而言,西北地区的土壤有机碳储量主要与年平均降水量呈正相关关系,华北地区和西北地区的土壤有机碳储量均与年平均气温呈负相关关系,在华东地区对土壤有机碳储量的影响相对显著的化学因子是可溶性有机碳(DOC).

植物根系微生物组在宿主生长发育、养分吸收以及病害抵御等方面发挥重要作用。为探究小麦根系微生物组变化与黄花叶病发生的关联机制,进而寻求小麦黄花叶病的生物防治方法,本研究采集了健康(H)、中度发病(M)和重度发病(S)小麦根系样品,研究了不同发病程度下小麦根内细菌群落结构及其环境驱动机制。结果表明:随着发病程度的增加,小麦根内细菌群落丰富度呈下降趋势。细菌群落结构在不同发病程度之间显著分异,且与根际土壤养分含量变化有关。其中短小杆菌属(Curtobacterium)、根瘤菌属(Rhizobium)、中慢生根瘤菌属(Mesorhizobium)、鞘氨醇单胞菌属(Sphingomonas)、人藤黄色杆菌属(Luteibacter)在发病小麦根内富集,其相对丰度与根际土壤中硝态氮(NO-3-N)、有效磷(AP)、有机碳(SOC)、全磷(TP)、全钾(TK)、植物体内碳(PC)含量呈显著正相关,与根际土壤中铵态氮(NH+4-N)、镁(Mg)含量呈显著负相关。泛菌属(Pantoea)在健康小麦根内富集,其相对丰度与植物体内氮(PN)含量呈显著正相关。以上结果表明,小麦根内细菌群落结构变化与小麦黄花叶病的发生及根际土壤养分含量增加有关。

连作障碍是限制甜瓜产业绿色可持续发展的重要因素。为明确土壤熏蒸和微生物菌剂缓解甜瓜连作障碍的效果及其土壤生态效应,优选防治大棚甜瓜连作障碍的措施,本研究比较了3种土壤熏蒸剂(棉隆、漂白粉、威百亩)和3种菌剂/菌肥(济元链复合微生物菌剂、硒霉菌复混肥料、聚谷氨酸复合微生物菌剂)施用对连作甜瓜产量、品质以及土壤pH、土壤电导率、养分含量、酶活性和微生物群落组成的影响。结果表明:与常规施肥相比,威百亩熏蒸条件下甜瓜单株结果数和产量分别降低27.7%和30.9%;棉隆处理土壤电导率、有效磷、速效钾含量分别降低31.9%、67.2%和26.6%。土壤熏蒸对细菌群落多样性无显著影响,但显著增加了土壤真菌群落多样性以及未知真菌物种的相对丰度。在促进土壤中生防促生细菌(如:Rokubacteriales、Ktedonobacteria、Thermoleophilia和Microbispora)积累的同时,棉隆熏蒸也加剧了土壤病原真菌(如:Ciboria)的积累。相反,3种微生物菌剂/菌肥施用条件下,连作甜瓜的产量、中心糖和边糖含量分别增加35.7%、3.5%和8.8%,土壤全氮、全碳含量,碳、氮、磷循环相关酶活性及相关功能微生物(如:Dadabacteriales、Steroidobacter、Dongia和Arthrographis)相对丰度均显著增加。聚谷氨酸复合微生物菌剂对大棚甜瓜产量及品质的形成、土壤质量和微生物生态功能的提升效果最佳。
