Abstract:
Taking muskmelon as the test material，a pot experiment was conducted to investigate the effects of different treatments (single application/combination) and application methods (foliar spray/seed soaking/root irrigation) of Bacillus velezensis and Trichoderma harzianum on the growth characteristics，root morphology，photosynthetic traits，and physiological properties of muskmelon seedlings,in order to provide references for muckmelon seeding cultivation.The results showed that under the same application method，Bacillus velezensis and Trichoderma harzianum could promote the growth of melon seedlings，improve their photosynthetic and physiological characteristics and root morphology，and the combined application had the best effect.Under the same fungicide treatment，root irrigation and seed soaking treatment had the best effect on the growth of melon seedlings.There was no significant difference in the growth promotion effect of fungicide compound combined with root irrigation or soaking treatment on seedlings，but compared with the control，it had a significant promotion effect on plant height，stem diameter，SPAD value and whole plant dry weight of melon seedlings.The net photosynthetic rate，stomatal conductance and transpiration rate were significantly improved.The contents of catalase，superoxide dismutase，peroxidase，catalase，soluble protein and soluble sugar in leaves were increased，and the content of malondialdehyde was decreased.It promotes the total root length，taproot length and root surface area.In conclusion，the synergistic application of Bacillus velezensis and Trichoderma harzianum had a promoting effect on the growth of melon seedlings under root irrigation or soaking application.
