Problems solved by technology

Among them, the first four methods cannot promote the rapid healing of the wound site of the injection hole, while spraying the drug has the disadvantages of high drug cost, easy waste, difficult operation, and unsatisfactory effect
The slow wound healing speed will be conducive to the invasion of insects and germs, which will hinder the growth of trees and even lead to their death, causing great economic losses.

preparation example Construction

[0022] In the present invention, the preparation method of the bark willow extract preferably comprises: extracting the roots of bark willow with methanol, and the obtained extract is bark willow extract. The method of the extraction is not particularly limited in the present invention, and the extraction is preferably performed by ultrasonic waves, and the frequency of the ultrasonic waves is preferably 80-90 Hz.

[0023] Wherein, the mass ratio of the willow bark to methanol is preferably (500-1000) g:(2000-4000) mL, more preferably 1000 g: 4000 mL. In the present invention, the extract of willow willow has insecticidal effect.

[0024] The bulking agent of the present invention is preferably activated carbon powder and / or sawdust, and when the bulking agent is activated carbon powder and sawdust, it is preferably mixed in an equal mass ratio. The source of the loosening agent is not particularly limited in the present invention, and conventional commercially available prod...

Embodiment 1

[0033] The filler is composed of solid and liquid substances. The solid substance is 8g of peach gum powder and 0.8g of activated carbon powder; the liquid substance is 8mL of 40% alcohol solution, 4.8mL of garlic essential oil, 0.8mL of naphthalene acetic acid solution and 0.4mL of willow extract . Wherein, the mass volume ratio of solid substance and liquid substance is 0.629g:1mL. Wherein, the bark willow extract is obtained by ultrasonic (80 Hz) extraction at room temperature with 500 g of bark willow root dry powder and 2000 mL of methanol.

[0034] Preparation method of filling agent:

[0035] After mixing the adhesive with an organic solvent, add a fungicide and place it in a closed container, heat it in a water bath at 60°C for 10 hours until the adhesive is completely dissolved; then add 1 mg / L naphthaleneacetic acid solution and willow extract, and Stir evenly; then add activated carbon powder, and continue to stir to obtain a filler.

Embodiment 2

[0037] The filling agent is composed of solid and liquid substances. The solid substance is 10g of peach gum powder and 1g of activated carbon powder; the liquid substance is 10mL of 40% alcohol solution, 6mL of garlic essential oil, 1mL of naphthalene acetic acid solution and 0.5mL of willow extract. Wherein, the mass volume ratio of solid substance and liquid substance is 0.157g:1mL. The extraction method of the bark willow extract and the preparation method of the filling agent are the same as in Example 1.

Abstract

The invention provides a filling agent for repairing tree damage, a preparation method and application thereof, and relates to the technical field of garden and park tree protection and repair. The filling agent comprises an adhesive, an organic solvent, a bactericide, a wound healing agent, a periploca sepium bunge extract and a bulking agent, wherein a ratio of the adhesive to the bulking agentto the organic solvent to the bactericide to the wound healing agent to the periploca sepium bunge extract is (8-10) g:(0.8-1) g:(8-10) mL:(4.8-6) mL:(0.8-1) mL:(0.4-0.5) mL, the adhesive comprises atleast one of peach gum, shellac and silica gel, the wound healing agent comprises a naphthylacetic acid solution and / or an indolebutyric acid solution, and the bulking agent comprises activated carbon and / or sawdust. The filling agent provided by the invention can activate a tree immune system, enhance metabolism, enhance stress resistance of a tree body, sterilize and disinfect, prevent and treat water loss and promote wound healing, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of garden tree protection and restoration, in particular to a filling agent for repairing tree damage, a preparation method and application thereof. Background technique [0002] Trunk injection technology (Truck injection) is to inject pesticides into the trunk in a certain way, so that it can enter the plant body and be transported to various parts with body fluids, so as to prevent and control pests and diseases. Compared with traditional external application techniques such as foliar spray and soil application, it has the characteristics of high utilization rate of liquid medicine, wide insecticidal spectrum, environmental protection, no pollution, safe use, simple and easy operation, and less affected by weather. As a very ideal environment-compatible pesticide application technology, this technology has been applied in forests, parks, urban landscaping, and roadside tree pest control. However, after t...
