Identification and Effects of Growth Promoting Rhizobacteria Isolated from Rhizosphere of Cotton
摘要
Abstract
[Objective ] The research aimed to identify promoting rhizobacteria separated from cotton rhizosphere preliminarily and observe the colony characteristics and cell characteristics. [Method] Normal bacteria identification method and Vitek-AMS instrument GNI test card was a-dopted. [Result] Strain WPC1 was Pseudomonas spp. ,strain YPL2 was Pseudonwnas spp. ,strain Cl was Enterobacter cloacae,and strain WPC2 was Agrobacterium ssp. Results of the germinative test indicated that all treatments had significant difference with control in germination vigor, germination rate,roots length,and stems length, which were higher than control by 2. 86% ~ 12. 86% ,2. 01% ~ 14. 78% ,14. 48% ~ 19. 39% , 6. 54% ~ 18.55% .respectively. Results of pot test indicated that all treatments had significant difference with control in chlorophyll content,plant height and R/T,which were higher than control by 0. 8% ~ 17. 3% ,2.7% -11. 18% ,34. 48% ~ 72.41% .respectively. Results of field experiment showed that all treatments had significant difference with control in the seedling emergence rate and growth-promoting of rhizobacteria, which could promote the seedling emergence of cotton. [ Conclusion ] The effect of strains KL5, WPL2 as bacterial manure was relatively stable, and they had growth promoting effect. Germination rate of combination KL5.KL3 +WPL2,YPL2 reached the maximum,and they could be used as superior strains.关键词
