| 摘 要： | 目的通过对棉花根际促生细菌N2126、P1108和K2116菌株单独接种和混合接种,根据这些菌株的固氮、解磷、解钾能力和细胞数量的变化,了解它们之间的相互作用。方法将这3株菌株设置4个不同的组合:N2126+P1108、P1108+K2116、N2126+K2116及N2126+P1108+K2116,分别测定培养液中全氮含量,水溶性磷、钾含量和细胞数量。结果P1108对N2126的生长有促进作用但抑制K2116的生长,N2126和K2116之间存在拮抗作用。N2126、P1108和K2116混合培养后,三者细胞数量分别占培养液中细胞总数的6.4%、89.2%和4.4%;培养液中的全氮含量比不接种时下降了0.7%;水溶性磷、钾含量比不接种时分别增加了19.0%和12.2%。结论P1108为3株菌株混合培养时的优势菌株,3株菌株混合培养有助于磷、钾释放。 |

| Abstract: | Objective To study the interactions between a N-fixation bacterium N2126,a Phosphobacterium P1108 and a K-releasing bacterium K2116 of cotton rhizosphere based on their N-fixing,P-releasing or K-releasing ability through incubation of the strains in media individually or in pairs of different combinations.Method Four different combinations were set up: N2126+P1108,P1108+K2116,N2126+K2116 and N2126+P1108+K2116.The content levels of total nitrogen,soluble P and K in the media were detected after five days.The... |
