Abstract:

Straw extract was sprayed on the leaves of strawberry fruits to explore the effect of different treatment doses
on the yield, single fruit weight, infection incidence, and soluble sugar content, especially antioxidants (ascorbic acid,
anthocynidin, and total phenols) of strawberry fruits. The results showed that the optimum spraying conditions of straw
extract were 1 200 mL per hm2 once every 11 days for three doses. Under these conditions, the yield, single fruit weight, and
nutrients, especially ascorbic acid of strawberry fruits were significantly improved, and the commercial value of strawberry
fruits was greatly enhanced.

Key words: strawberry, yield, disease, antioxidant, ascorbic acid
