Abstract:

In order to evaluate the application effect of amino acid organic water-soluble fertilizer, a field experiment was conducted using strawberry as the test material. On the basis of conventional fertilization, the treatment group received root irrigation with 500 mL of amino acid organic water-soluble fertilizer applied as a 500-fold dilution per 667 m2 per application during the growth season (applied 5 times in total during the seedling and flowering-fruiting stages), with an equal volume of water used as the control. The results from two-season strawberry experiment showed that, compared with the control, the application of amino acid organic water-soluble fertilizer promoted strawberry growth, significantly (p<0.05) increased the fruit number per plant of the first inflorescence by 16.7%-23.9%, promoted fruit coloration, and significantly increased the single fruit weight and yield of strawberry by 9.11%-9.88% and 16.13%-21.96%, respectively. In addition, the treatment decreased the score on acid content, thereby improving strawberry taste and flavor. In conclusion, root application of amino acid organic water-soluble fertilizer can effectively improve strawberry growth, promote fruit setting and maturation, increase yield, and enhance fruit quality.
