3. The experimental method comprises the following steps: selecting crabapple trees with similar growth vigor, spraying a medicament (60 kilograms of liquid medicine per mu) on the whole plant in a spore germination period, setting 3 times of repetition, and photographing at each treatment fixed point to observe experimental change.

4. Data statistical analysis: the analysis was performed using dpsv7.05(Duncan) statistical software. And (5) measuring the anthocyanin content and the flowering time of the plant flowers. Measuring absorbance OD value with spectrophotometer, and calculating anthocyanin relative content with OD value. The flowering time, starting with 5% flowers open and counting the number of days of intermediate retention by the time flowers fall to the remaining 5%, was selected for three replicates.
