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.盆栽试验结果表明,与...

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 ...
