Abstract: Taking the ‘Hongyan’ strawberry in Dandong area as the test material, five fertilizer formulas were set up, the effects of fermented bacterial fertilizer on the ripening and quality of local greenhouse strawberry were studied, in order to provide reference for improving the quality and ripening period of strawberry in greenhouse.The results showed that the treatments with fermented bacterial fertilizer were better than the control group in improving the ripping and quality of strawberries in greenhouse; from the comparison between treatment 1 and treatment 2,it could be seen that the effect of fermented granules was better than that of fermented organic base fertilizer.For single fruit weight, treatment 4 was slightly better than each treatment; but treatment 3 had the best comprehensive evaluation in terms of ripping, continuous stubble, hardness, sugar content, fruit shape, storage period, and disease resistance, compared with the control, the first fruit stage was 23 days earlier, the full fruit stage was 22 days earlier, the hardness increased 0.7 kg·cm^-2,the sugar content increased 3.1%,single fruit weight increased 12.88 g, and the standard rate of fruit shape reached 90%.It showed that after the combination of farmyard manure and ferment-bacterium fertilizer to form a stable long-acting fertilizer, and applying the quick-acting fertilizer of the fermented granule was a scientific formula to improve the ripping and quality of greenhouse strawberries.
