Study on Three Species of Bacteria Fertilizer Improving Drought Resistance and Disease Resistance of Turfgrass

Using Festuca arundinaces as the material, the authors applied bacteria fertilizer E, F and H on the turfgrass, then inspected the effect of bacterial fertilizer on the drought resistance and disease resistance of turfgrass. The result indicated that the turfgrass applied with both bacterial fertilizer and chemical fertilizer grew better than that of other treatments, the contents of proline, nitrate reductase(NR), chlorophyll increased, while electrolyte leakage and the content of MDA declined, the drought resistance of the turfgrass was advanced. After the turfgrass were inoculated by Rhizoctonia solani, the number of disease spot of turfgrass which added bacteria fertilizer and chemical fertilizer were less than that of other treatments, and the contents of peroxidase, polyphenoloxidase and phenylalanine ammonia-lyase were higher than that of other treatment. The resistance of turfgrass on the Rhizoctonia solani was advanced.
