Strawberries

1. Fruits (yield, coloration, internal quality (nutritional composition))

Treatment: The experiment set up four treatments, namely CK (KH2PO4 1g/L), FA-K0.5 (0.5g/L), FA-K1 (1g/L), and FA-K1.5 (1.5g/L). Four batches of strawberries with roughly the same fruit set were selected for fertilizer application, while other procedures followed conventional practices.

Result: Compared with the control, the application of fulvic acid can significantly promote early coloring of strawberries.
