优良菌种是微生物肥料的基础,研究微生物肥料中低温适应型菌株在低温条件下的促生性,对于提高南方冬闲时植物修复重金属污染农田具有重要意义.通过形态观察及18S rRNA基因序列分析,对菌株进行了鉴定,在此基础上进行植物盆栽试验,分析了3株不同根际促生菌单独施加及其与肥料（鸡粪+微量元素）配施对镉砷复合污染土壤中巨菌草迁移累积Cd、As的影响.分离菌株的初步鉴定结果表明,3株根际促生菌（M1、M2、M3）分别为云南木霉（Trichoderma yunnanense）、卵形孢球托霉（Gongronella butleri）、越橘间座壳菌（Diaporthe vaccinii）.纯培养试验表明,M1、M2、M3均可在南方冬季低温条件下生长.盆栽试验结...

Excellent strains are the basis of microbial fertilizers.In order to improve the phytoremediation of soil heavy metal contaminated farmland,it is of great significance to study the growth-promoting ability of low-temperature-adapted strains in microbial fertilizers under low-temperature conditions during the winter slack in southern China.Strains were identified through morphological observation and 18S rRNA gene sequence analysis.On this basis,a pot experiment was carried out to study the effects of three different plant growth-promoting rhizobacteria (PGPR) applied alone or in combination wi...
