Method for delaying blossoming of kernel-apricots as well as blossoming-delaying solution and preparation method of blossoming-delaying solution

The invention discloses a method for delaying blossoming of kernel-apricots as well as a blossoming-delaying solution and a preparation method of the blossoming-delaying solution. Based on 1000mL of the solution, the solution comprises the following components by volume: 0.1-1mL of water aqua ethephon, 20-25mL of glycerinum, 20-30mL of sorbic enol, 10-15mL of azone, 5-10mL of polyvinyl alcohol solution and 0.25-0.5mL of simethicone; the purity of ethephon in water aqua ethephon is greater than or equal to 90wt%. According to the method disclosed by the invention, a solution for avoiding late frost for kernel-apricots is developed by massively screening kernel-apricots treated by different growth regulators in different concentrations and at different times and researching the influence of the prepared solution on delaying blossoming of the kernel-apricots. The solution is further applied to avoiding late frost for kernel-apricots, thereby laying a good foundation for a high yield cultivation technology of kernel-apricots. By using the solution prepared by the method, the flowering period of the kernel-apricots can be delayed by 17 days to the maximum extent.
