摘要:
为了获得荒漠植物根际土壤中的优良固氮菌,探究其对红砂幼苗氮代谢的影响,验证固氮菌的促生效果。本研究采用稀释涂布平板法,利用Ashby固体培养基从红砂根际土中分离得到4株固氮菌,通过形态学、生理生化特征以及16S rDNA序列分析鉴定菌株的分类地位及促生特性。结果表明,菌株Y3与Y2为芽孢杆菌,菌株P4为桑树肠杆菌,菌株N12为阴沟肠杆菌;4株固氮菌均能提高红砂幼苗叶和根中硝酸还原酶(NR)、谷氨酰胺合成酶(GS)、谷氨酸合成酶(GOGAT)活性;接种菌株后红砂幼苗根长、叶片相对含水量、地上部和地下部鲜重间均有差异(P<0.05);其中,固氮菌P4促生效果最为显著,接种P4菌株后叶和根中NR活性分别提高了31.99%、34.63%(P<0.05),GOGAT活性分别提高了25.63%、25.08%(P<0.05),GS活性分别提高了23.31%、24.30%(P<0.05),且根长、叶片相对含水量、地上部和地下部鲜重分别增加27.99%、20.75%、33.34%、33.25%(P<0.05)。综上,4株固氮菌可促进红砂幼苗的生长发育,提高其成活率,同时也为研发微生物菌剂提供了优质菌种资源。
