Abstract:

In order to investigate the effect of earthworm liquid fertilizer on strawberry growth, and obtain the suitable fertilization formulas for green production of strawberry. field experiments were conducted in Data Village, Dongchen Town, Xiangshan County, The results showed that the T2 treatment had the earliest harvest period with an increase of 9 days compared with CK treatment. The yield from the plots of T2 treatment was the highest (23 391 kg·hm^-2), which was higher than CK treatment by 4 726 kg·hm^-2 with an increment of 25.3%. Additionally, T2 treatment resulted in significant better strawberry quality than CK treatment (P<0.05), in terms of average single fruit weight, soluble solids content, fruit hardness, and total acid content of 20.43 g, 9.8%, 273.12 kg·cm^-2, and 6.59 g·kg^-1, respectively, with an increment of 21.0%, 1.4 percentage point, 11.4% and 32.3%, respectively.

Key words: strawberry, earthworm organic liquid fertilizer, yield, quality
