Preparation method of root system anti-freezing solution

Abstract

The invention provides a preparation method of a root system anti-freezing solution. The preparation method comprises the following steps: preparing the following materials: paraffin, calcium chloride, methanol, fulvic acid, glycerol, distilled water, mono carboxylic acid, ramulus mori, pine needle, rhizoma zingiberis and herb of diffuse dayflower; A, mixing methanol, glycerol, distilled water and mono carboxylic acid, uniformly stirring, then adding fulvic acid into the mixture, adding paraffin (liquid paraffin) into the mixture, uniformly stirring and leaving to stand; B, placing ramulus mori, pine needle, rhizoma zingiberis and herb of diffuse dayflower into a closed vessel, adding an ethanol solution with the mass percent of 75 into the closed vessel, infiltrating and soaking the active components for 12 h, after that, charging the active components into a percolator, adding ethanol with the mass percent of 75 for soaking, then starting to collect the percolating liquid, heating the collected percolating liquid with 75 percent of ethanol to reclaim ethanol so as to obtain an extract, adding the extract into calcium chloride to enable the extract to be dissolved, heating dissolved calcium chloride to be 40-50 DEG C, and sterilizing for later use; C, fully mixing the product obtained in the step A and the product obtained in the step B. The proportioning is simple, the use is convenient, frost injury loss of trees is greatly reduced and the anti-freezing effect is good.

Description

Technical field: [0001] The invention relates to the technical field of tree protection, in particular to a method for manufacturing root system antifreeze. Background technique: [0002] The sudden death of trees in winter is mostly caused by the freezing of the root system. Root neck frost damage, because the root neck stops growing the latest and starts to move earlier, the cold resistance is poor. At the same time, it is close to the surface, and the temperature changes greatly, so the root neck is vulnerable to low temperature and large temperature changes, causing the cortex to be frozen (one side turns brown in a ring and then dries or rots). Freezing damage to the main stem: First, the sunburn on the sunny side (especially the southwest side) in winter. Due to the large temperature difference between day and night during early winter and early spring, the skin tissue moves with the increase of sunlight temperature, and the temperature drops suddenly at night and ...

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.
