Abstract:
Taking tomatoes (cv.‘Hezuo 903’)，eggplants (cv.‘Zihongchangqie’)，and pepper (cv.‘Shenhe xiangxian’) as experimental materials,the effects of different treatments on the growth of solanaceous vegetables and the microbial population in the substrate were investigated by incorporating Bacillus subtilis，Bacillus velezensis，and Bacillus licheniformis，either individually or in combination，into the seedling substrate，in order to screen the most suitable compound microbial agent for the seedling of solanaceous vegetables，and provide reference for fostering robust seedlings of these vegetables.The results showed that the addition of three Bacillus strains (Bacillus subtilis, Bacillus velezensis，and Bacillus licheniformis) to the seedling substrate，either individually or in combination，promoted the growth of tomato seedlings，with the combined treatment showing the most significant effect.In particular，the combined treatment of 7.5×106 CFU·mL-1 Bacillus subtilis and 5.0×106 CFU·mL-1 Bacillus velezensis demonstrated the most optimal growth-promoting effects.The seedling growth indicators，chlorophyll content，and seedling vigor index were significantly higher than those of the control and other individual treatments.This treatment increased the seedling vigor index by 37.50% to 70.00% compared to the control，by the 40th day after sowing，enhanced the bacterial and actinomycetes populations in the substrate by 5.19-11.07 times and 2.69-3.28 times，respectively.In summary，the optimal composite microbial agent for promoting robust seedling cultivation and plant growth in solanaceous vegetables was the combination of Bacillus subtilis and Bacillus velezensis.
