Late frost avoiding method for kernel apricots, late frost avoiding solution and preparation method of late frost avoiding solution

Abstract

The invention discloses a late frost avoiding method for kernel apricots, a late frost avoiding solution and a preparation method of the late frost avoiding solution. The late frost avoiding method for the kernel apricots comprises the following steps that S1, ground watering: watering is conducted 7-10 days before normal flowering of kernel apricot trees; S2, spraying of the late frost avoiding solution; S3, spraying of lime water: the lime water with the concentration of 1-1.5% is prepared, and the lime water is comprehensively sprayed to the crowns of the kernel apricot trees; S4, sleeving of transparent plastic film sleeves: the transparent plastic film sleeves are arranged on the crowns of the kernel apricot trees in a sleeving mode, and the crowns of the kernel apricot trees are completely covered with the transparent plastic film sleeves; and the late frost avoiding solution is prepared from components as follows: purified water, a growth regulator and a leaf fertilizer, the growth regulator is prepared from 0.3%-0.5% of brassinolide and 0.3%-0.5% of naphthaleneacetic acid potassium salt, and the leaf fertilizer is prepared from 0.1%-0.2% of liquid boron and 0.3%-0.5% of monopotassium phosphate. According to the method, opposite watering is adopted to reduce the temperature, the transparent plastic film sleeves are additionally arranged, and the late frost avoiding solution is sprayed in a matched mode, so that the flowering time of kernel apricots can be effectively delayed, and striking from early spring late frost is avoided.

Description

technical field [0001] The invention relates to the technical field of planting dry fruit economic forests, in particular to a method for avoiding late frost in kernel apricots, a solution for avoiding late frost and a preparation method thereof. Background technique [0002] Apricot for kernels is the general term for the fruit trees of the genus Apricot whose main product is almonds. Apricots for kernels have high economic value. With the gradual improvement of people's understanding of dry fruit economic forests, kernel apricots have become an important resource for the development of dry fruit economic forests. Apricot for kernel is an important raw material in food industry and pharmaceutical industry, and also a fresh fruit with unique taste. At the same time, apricot tree is a drought-resistant tree species, sunshine-loving, and easy to manage. It is the preferred tree species for planting in plains, mountainous areas, and deserts. It has wide adaptability, great pote...

Problems solved by technology

[0005] To sum up, referring to the existing methods of avoiding night frost, spraying night frost solution on apricot trees for kernels is far from enough. The weather factors cannot be accurately determined, and it is impossible to detect whether the phenomenon of night frost will occur, so relying on spraying night frost solution Delaying the flowering time of apricot trees for kernels can achieve the effect of avoiding late frost, but there is no other way to assist, the effect of avoiding late frost is not comprehensive and the duration is not long enough, and it is easy to be attacked by late spring frost
