Preparation method of antifreezing agent

Abstract

The invention provides a preparation method of an antifreezing agent, wherein the preparation method comprises the following steps: A, mixing and uniformly stirring glycerinum, salicylic acid, tea polyphenol and glacial acetic acid, adding acetic acid into the mixture, choosing liquid paraffin, adding the paraffin into the mixture, stirring uniformly and standing; B, putting bamboo leaves, ochre, elsholtzia, pine needles into a closed container, adding an ethanol solution with the mass percent of 75%, infiltrating and steeping the active components for 12 hours, putting the active components into a percolator, adding the ethanol solution with the mass percent of 75%, soaking, starting to collect a percolate, heating the collected 75% ethyl alcohol percolate, and recovering ethyl alcohol so as to obtaining an extract; adding the extract into the vegetable oil, dissolving the extract into the vegetable oil, heating the vegetable oil dissolved with drugs to 40-50 DEG C, and sterilizing for use; C, fully mixing the mixture obtained in the step A and the mixture obtained in the step B, and detecting the ion content, wherein the contents of Cu, Fe, Mn, Zn and B are larger than or equal to 100 g / L. The preparation method is simple in coordination, convenient to use and good in antifreezing effect, and greatly reduces the loss caused by the freeze injury of a tree.

Description

[0001] Technical field: [0002] The invention relates to the technical field of forest protection, in particular to a method for manufacturing an antifreeze agent. [0003] Background technique: [0004] The frost damage of crops, such as tree freeze damage, mainly occurs on the inward side of the branch. Symptoms are cortical discoloration, necrotic depression, or vertical cracking along the main trunk. Due to the narrow annual rings at the branches, underdeveloped ducts, poor support, low nutrient accumulation, poor cold resistance and other reasons, the ducts rupture, resulting in gum flow in the next spring. At the same time, because snow is easy to accumulate at the branches, the bark will be soaked to make the tissue soft after the snow melts, and it will be damaged if the temperature drops suddenly. [0005] In the traditional prevention and control of tree frost damage, lime and lime sulfur are used to whiten the branches and trunks, which can reduce the damage t...

Problems solved by technology

However, this method is not suitable for colder areas. In colder areas, most of them use tree trunks to wrap straw curtains, and then wrap plastic cloth outside the straw curtains to prevent freezing.

The operation is cumbersome, the labor intensity is high, and it needs to be disassembled again next spring, resulting in a serious waste of resources. In view of this technical problem, it is necessary to have a simple proportioning, easy to use, which can greatly reduce the loss of tree frost damage and antifreeze effect.
