Abstract:

With the development of modern agriculture, improving the yield and quality of melon while achieving sustainable planting has become an urgent problem in agricultural production. This study aimed to investigate the effects of microbial fertilizer on soil fertility, melon quality traits, and stress resistance. Different fertilization timings, dosages, and types were set up to measure melon growth traits (plant height, leaf moisture content, fruit moisture content, stem moisture content, chlorophyll content), antioxidant enzyme activities ( CAT, SOD, POD), quality traits (total sugar, reducing sugar, vitamin C, titratable acid, soluble solids content), soil nutrient contents (total nitrogen, total phosphorus, total potassium, iron, zinc, calcium, magnesium, boron), and the disease and pest control efficacy. The results showed that the microbial fertilizer significantly(p<0.05) enhanced soil fertility and improved the melon quality. Compared with CK, the soil iron, zinc, calcium, boron, magnesium contents in BL3 treatment (applying 10 bags of bacterial fertilizer per 667 m2 in early November) significantly increased and reached the highest level. Total sugar, reducing sugar, vitamin C, and soluble solids content all significantly increased and reached the highest level. BL3 treatment had the best disease and pest control efficacy, and the activities of CAT, POD, and SOD were also the highest. In summary, microbial fertilizer had advantages in soil fertility, quality traits, and stress resistance. This study provides scientific basis and technical support for efficient melon cultivation.

Key words: microbial fertilizer, facility melon, soil nutrient, quality trait, pest and disease control efficacy
