A method for delaying flowering of apricot for kernels, solution for delaying flowering and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of delayed flowering of apricot trees for kernels. More specifically, it relates to a method for delaying flowering of kernel apricot, a delayed flowering solution and a preparation method thereof. Background technique [0002] Apricot for kernel (Prunus armeniaca × sibirica Linn.) is a deciduous tree of Rosaceae. Apricot for kernel is an important woody grain and oil tree species in China, and the cultivation area of ​​apricot flat in the country is about 250,000 hm 2 It is distributed from Tailai County, Heilongjiang Province in the north and Xijiadian Town, Danjiangkou City, Hubei Province in the south. At present, the national output of almonds for kernel use is nearly 20,000 tons, while the domestic market needs 10,000 tons for medicinal and beverage use, so there is a big contradiction between supply and demand. Almonds for kernels include bitter almonds and sweet almonds. Bitter almond is one of C...

Problems solved by technology

Many scholars at home and abroad have carried out a lot of research work on the cultivation techniques of kernel apricots to avoid late frost by delaying flowering, such as irrigation, water spraying, white coating, lime spraying, sunshade net coverage, etc., but due to conventional cultivation Technical measures to delay the flowering time are generally about 3d to 4d, the effect is not obvious, and it is impossible to avoid the harm of late frost in the flowering stage or young fruit stage of kernel apricot. Effective technical measures to solve the hazard of kernel apricot late frost have not yet been formed in production.
