Abstract

Abstract: To study the application effect of biodegradable amino acid fertilizer from feather on strawberry cultivation, pot experiments using biodegradable amino acid fertilizer and commodity amino acid fertilizer as topdressing fertilizer were carried out. Influence of different concentration of biodegradable amino acid fertilizer and commodity amino acid fertilizer on strawberry vegetative growth, chlorophyll content and fruit quality at different periods were analyzed. The results showed that the biodegradable amino acid fertilizer from feather with free amino acid content of 0.364 g?L_-1 significantly improve strawberry plant height and leaf area at low temperature. In the appropriate temperature, the treatment can improve strawberries chlorophyll relative content (SPAD). All treatments using amino acid fertilizer can improve the quality of strawberry fruit, however, the soluble sugar, sugar acid ratio and VC content of strawberries watering biodegradable amino acid fertilizer from feathers with free amino acid content of 0.364 g?L_-1 were significantly higher than other treatments. Biodegradable amino acid fertilizer from feather has application potential as a new kind of biological fertilizer.
