The application relates to an application method of L-tert-leucine for improving the quality and storability of Gala apples, which comprises the following steps: selecting a test apple orchard base, selecting Gala apple trees, and spraying different concentrations of exogenous L-tert-leucine on the selected test apple trees in a fruit development period; picking 8-9 mature Gala fruits, storing the fruits, and comparing the fruit quality indexes of different groups and comparing various measured data. According to the application method, spraying 500 mg / L mass concentration L-tert-leucine on the leaves of Gala apples in a growth period can significantly promote the yellow coloration and brightness increase of the Gala apples at the time of harvesting, improve the fruit hardness, TSS content, TA content, soluble protein content and free amino acid content, is beneficial to maintaining the fruit hardness and soluble protein content during cold storage, delaying the decrease of the fruit hardness and soluble protein content, inhibiting the decrease of the TSS content and TA content and the increase of the free amino acid during cold storage, and keeping the Gala apple fruits with lower POD activity and higher SOD activity.
