摘　　要：在可持续农业中,寻找促进植物生长和提高作物产量的生态友好型方法是当务之急。腐植酸(HA)和植物根际促生菌(PGPR)是利用天然生物活性物质的最有效方法之一。本研究的目的是分析HA对马铃薯(Solanum tuberosum L.)接种PGPR(巨大芽孢杆菌Bacillus megatorium和枯草芽孢杆菌Bacillus subtilis)的影响,并与对照和推荐剂量的氮磷钾进行比较。将HA(200,400和600 kg/ha)和PGPR单一或混合施用,以及氮磷钾(50%和100%)处理的种薯块茎分别种植在处理土壤和未处理的土壤中,对马铃薯植株生长、分类块茎产量、品质和矿物质含量进行了评价。接种了PGPR和HA处理的马铃薯在生长、块茎产量和品质方面都有极显著的提高。接种PGPR后,马铃薯块茎大小、重量、比重、干物质、淀粉、蛋白质和矿物质含量(Cu除外)得到改善,添加HA后效果进一步增加。与对照相比,接种PGPR和400 kg/ha HA混合施用,马铃薯块茎总产量提高了约140%,而传统常规施肥(100%氮磷钾)处理仅使马铃薯提高了111%。结果表明,这种综合方法具有加速马铃薯从传统生产向可持续生产转变的潜力。In sustainable agriculture,seeking eco-friendly methods to promote plant growth and improve crop productivity is a priority.Humic acid(HA)and plant growth promoting rhizobacteria(PGPR)are among the most effective methods that utilize natural biologically-active substances.The aim of the present study was to analyze the effect of the presence of HA on potato(Solanum tuberosum L.)inoculation with PGPR(Bacillus megatorium and Bacillus subtilis)when compared to control and recommended doses of NPK.Seed tubers treated by humic acid(200,400 and 600 kg/ha)and PGPR,separately or in combination,and NPK(50%and 100%)were planted into soil and untreated soil.Treatments were assessed for plant growth,classified tuber yields,quality,and mineral contents of potato tubers.There were highly significant increases in potato growth,tuber yields,and quality in PGPR and HA inoculated crops.Tuber size,weight,specific gravity,dry matter,starch,protein,and mineral contents(except Cu)were improved with PGPR treatments and further increased when administered with humic acids.Inoculation with PGPR mixed culture and 400 kg/ha HA increased total potato tuber yield by about 140%while conventional single treatment of 100%NPK fertilizer only led to an increase in potato production of 111%when compared to the control.The results demonstrated that this integrated approach has the potential to accelerate the transformation from conventional to sustainable potato production.
