英文摘要 | 1. Seven new native strains, one introduced strain #3 from USDA and the known best strain GY9-B5 were compared in field inoculation experiment at Taoyuan. The results showed that three of the new native strains namely GT23-A1, GP20-A1, GT23-B2 and the introduced strain #3 were more effective than GY9-B5, but with no significant difference among them. However, the strain GT23-A1 seems to be the best of all. 2. The results showed that both inoculation and nitrogen application can significantly increase the yield of soybean. The yields in the plots of inoculation combined with nitrogen application were higher than those of inoculation alone, however, with no significant difference. It was found that hte seed yields in the plots with 40 kg/ha of nitrogen were lower than those with Rh. japonicum inoculation. Inoculation with root nodul bacteria seems more economical than nitrogen fertilizer in raising the production of legumes. 3. Field inoculation experiments to compare the effectiveness of powder inoculant preserved for four different periods have been conducted on the farm of Provincial Chungli Vocational Agricultural School. The results showed that the powder inoculants preserved for a period of 11, 17 and 21 weeks were more effective than both that for 31 weeks and pure culture for 5 weeks in increasing the yield of seed. |
