PGPR复合菌剂对辣椒生长及根际土壤微生物结构的影响
PGPR复合菌剂 辣椒 促生作用 根际微生物
2020/5/26
为研究植物根际促生菌(PGPR)菌剂在田间条件下对辣椒的促生效果及其对根际土壤微生物结构的影响,以前期筛选到的 4株 PGPR菌株制备的复合菌剂为研究对象、辣椒为试验材料进行田间试验,分别设置了100%化肥组(CK)、100%化肥 +PGPR复合菌剂组和 80%化肥 +PGPR复合菌剂组共 3个处理,在幼苗期、始花期和坐果期对辣椒进行灌根,测定了不同处理组辣椒的株高及茎粗、产量和根际微生物的结构变...
筛选并鉴定了贵州烟区烟草根际促生菌(PGPR)菌株。测定PGPR产激素能力、定殖能力以及对烟草苗期促生作用,以具备多项促生能力为筛选标准,确定目标PGPR,再通过16S rDNA、平板对峙以及PCR技术对目标PGPR进行属鉴定、抗病能力测定。通过筛选获得的7株目标PGPR均能产生脱落酸、细胞分裂素、赤霉素和生长素。烟苗盆栽试验表明7株PGPR均具有促生效果,其中LX-7处理的烟苗鲜重和根系活力最大...
为了利用本地PGPR菌株改善云南植烟土壤质量,提高磷、钾等元素利用率,促进烤烟生长,在云南主要植烟区采集烤烟根际土壤样品31个,对根际土壤中的微生物进行分离,筛选和鉴定,共获得解磷、解钾或促生菌共773株,进一步筛选获得到了10株具有较强解磷、解钾或IAA促生作用的菌株。经鉴定发现10个菌株分别属于Bacillus(芽孢杆菌属)、Paenibacillus(类芽孢杆菌属)、Providencia(...
Influence of PGPR and AMF on antioxidant activity, lycopene and potassium contents in tomato
Fruit quality mycorrhiza rhizobacteria tomato
2011/1/11
In this study, the impact of inoculating tomato (Lycopersicon esculentum F1 Hybrid, GS -15) roots with plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhiza fungi (AMF) on fruit qualit...
从烤烟根际分离得到2株细菌菌株A03和B04,平板测定对3种烟草病害烟草角斑病、青枯病和赤星病的病原菌有较强的拮抗作用,其中B04菌株具有解磷能力。将该2菌株扩大培养制成菌肥按1%的比例拌入育苗基质中应用于烤烟漂浮育苗,试验不同菌肥处理对烟苗的影响。结果显示:播种后27 d,A03菌肥处理种子发芽率比对照显著提高53.1%;播种后39 d,A03和B04菌肥处理种子发芽率分别比对照提高5.5%和1...
