Abstract

The present application provides a water-soluble plant wound healing agent and a preparation method. The preparation raw materials of the healing agent include water, water-soluble lanolin, mussel mucopolysaccharide, sodium naphthaleneacetate, willow fresh branch extract and copper sulfate. The healing agent can form a thin film with strong water retention and air permeability when sprayed on the wound of the tree body, preventing water evaporation in the wound xylem, inducing the cambium cells to split faster and promoting the rapid growth of the cambium. Meanwhile, the healing agent can prevent external bacteria from entering the wound of the tree body, achieving the effects of bacteriostasis and sterilization, and avoiding secondary damage caused by pathogenic bacteria infection. After the wound is recovered, the water-soluble lanolin disappears due to volatilization and rainwater flushing, avoiding the burn caused by the invasion of oily substances into the bark. The healing agent has good liquid flowability, film-forming property and water retention, and the raw materials are simple and easy to obtain. The preparation process is simple, and the healing agent can be used to heal the wound under complex conditions such as high position, large area and large quantity by means of a spray pot, a small sprayer and the like, greatly improving the work efficiency.

Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of plants, and relates to a water-soluble plant wound healing agent and a preparation method. BACKGROUND

[0002] Forest trees, fruit trees and the like are important components of agricultural industry, and are of great significance in stimulating rural economy and constructing rural ecological civilization.

[0003] In the process of cultivation and growth, forest trees, fruit trees and the like need to be grafted and pruned to promote their good growth. In the process of grafting and pruning, the forest trees or fruit trees after pruning will leave wounds. In addition, the forest trees or fruit trees will also produce wounds after being mechanically damaged or having diseased spots removed. If the wounds are not healed in time, the chances of the tree body being infected with diseases such as rot disease, dry rot disease and annular disease will be greatly increased. In addition, forest trees such as chestnut and walnut have poor bark regeneration ability due to their nature, and the wounds after pruning are difficult to heal for a long time. Therefore, the wounds produced by forest trees, fruit trees and the like need to be smeared with a medicament to promote the wounds to heal as soon as possible and avoid secondary hazards such as bark cracking and pathogen infection.

[0004] At present, most of the commercially available tree healing agents are mainly in the form of ointments, and the medium is mostly oily substances. The ointment healing agent has a thick paste body and poor flowability, and must be smeared with a brush during use. For some tall trees, a high ladder needs to be used to smear the ointment healing agent, which is inconvenient to operate. If the pruning amount of some forest trees and fruit trees is large, and the sawing and cutting area is large, for example, apple trees and pear trees cultivated in an intensive manner, there is a problem of large smearing workload and inconvenient implementation. SUMMARY

[0005] The present application aims to provide a water-soluble plant wound healing agent and a preparation method to solve the problem of large smearing workload of ointment healing agent when large forest trees and fruit trees are pruned.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] The present application provides a water-soluble plant wound healing agent, and the preparation raw materials of the healing agent include water, water-soluble lanolin, mussel mucopolysaccharide, sodium naphthaleneacetate, willow fresh branch extract and copper sulfate. The water is ordinary tap water.

[0008] Water-soluble lanolin refers to PEG-75 lanolin oil, and the CAS code is 68648-38-4. The water-soluble lanolin is a light yellow flaky solid, has good water solubility and conditioning properties. In the present application, the water-soluble lanolin replaces the oily ingredients such as vaseline, lanolin, etc., and the prepared healing agent is water-soluble. When the water-soluble healing agent is sprayed on the wound of the tree, a thin film with strong water retention and good air permeability can be formed, which prevents the evaporation of water from the wood part of the wound, ensures the wetness of the wound, and realizes the rapid healing of the wound. After the tree sprouts for 2 months, the water-soluble healing agent disappears due to volatilization and rain washing, thereby avoiding the burning caused by the invasion of oily substances into the bark.

[0009] Mussel mucopolysaccharide is a kind of heteropolysaccharide, which is soluble in water and has strong hydrophilicity. The mussel mucopolysaccharide also has strong adhesion, which can improve the adhesion of the healing agent, prevent the adhesion agent from being washed by rain, and further prevent external bacteria from entering the wound of the tree.

[0010] Naphthalene acetic acid sodium refers to alpha-naphthalene acetic acid sodium, which is a white powder and is easily soluble in water. Naphthalene acetic acid sodium is a plant growth regulator, which can accelerate the cell division speed of the cambium and promote the differentiation of the cambium cells to form callus.

[0011] Willow fresh branch extract refers to the solution obtained by extracting fresh willow branches with an alcohol solution. The solution is rich in salicylic acid, which can induce the cambium cells to accelerate the division speed and promote the rapid growth of the cambium. At the same time, the willow fresh branch extract can also inhibit the breeding of bacteria and prevent various bacterial infections.

[0012] Copper sulfate refers to anhydrous copper sulfate, which is a white powder and is soluble in water. Copper sulfate can prevent the infection of wound rot disease and annular disease, thereby achieving the purpose of preventing bacteria.

[0013] The present application provides a water-soluble plant wound healing agent, which uses water as a medium. The water-soluble lanolin, mussel mucopolysaccharide, copper sulfate, naphthalene acetic acid sodium and willow fresh branch extract are dissolved in water to form a water-soluble healing agent. The water-soluble plant wound healing agent has good liquid flowability, film-forming property and water retention, can induce and rapidly promote the division of cambium cells, and promote wound healing.

[0014] The preparation raw materials of the water-soluble plant wound healing agent in the present application include 900-1000g of water, 40-60g of water-soluble lanolin, 40-60g of mussel mucopolysaccharide, 0.1-0.3g of naphthalene acetic acid sodium, 15-25g of willow fresh branch extract and 15-25g of copper sulfate.

[0015] According to the different use periods, the water-soluble plant wound healing agent provided in the application is divided into winter type and spring type, which can ensure healing before the rainy season and enhance the use effect. Among them, the winter type healing agent is mainly used for winter pruning of forest trees, and the application period is mainly from January to March, that is, the tree dormancy period. The spring type healing agent is mainly used in the budding period and rapid growth period.

[0016] For the winter type healing agent, the mass ratio of each component of the healing agent is water: water-soluble lanolin: mussel mucopolysaccharide: sodium naphthalene acetate: willow fresh branch extract: copper sulfate = 980: 50: 50: 0.2: 20: 20. Taking the preparation of 1000ml winter type healing agent as an example, the mass of each component is: 980g of water, 50g of water-soluble lanolin, 50g of mussel mucopolysaccharide, 0.2g of sodium naphthalene acetate, 20g of willow fresh branch extract and 20g of copper sulfate.

[0017] For the spring type healing agent, the mass ratio of each component of the healing agent is water: water-soluble lanolin: mussel mucopolysaccharide: sodium naphthalene acetate: willow fresh branch extract: copper sulfate = 980: 25: 25: 0.2: 20: 20. Taking the preparation of 1000ml winter type healing agent as an example, the mass of each component is: 980g of water, 25g of water-soluble lanolin, 25g of mussel mucopolysaccharide, 0.2g of sodium naphthalene acetate, 20g of willow fresh branch extract and 20g of copper sulfate.

[0018] Based on the water-soluble plant wound healing agent provided in the application, the application further provides a preparation method of the water-soluble plant wound healing agent, which comprises:

[0019] S01: Put sodium naphthalene acetate and copper sulfate into water, stir until completely dissolved, and form a mixed solution a.

[0020] S02: After mixing water-soluble lanolin, mussel mucopolysaccharide and the mixed solution a, heat and stir to dissolve under the condition of temperature 30-50℃ until completely dissolved to form a mixed solution b.

[0021] S03: After the mixed solution b is cooled to room temperature, the willow fresh branch extract is added and stirred uniformly to form a water-soluble plant wound healing agent.

[0022] Among them, the preparation method of the willow fresh branch extract comprises:

[0023] S031: Select one-year-old fresh willow branches that are about to germinate, and cut them into willow branch sections with a length of 1-2cm;

[0024] S032: Soak the willow branch sections in an alcohol solution with a concentration of 25% for 24h, shake once in the middle; filter out the willow branch sections to obtain a willow fresh branch extract, which is refrigerated for use.

[0025] The present application has the following advantages:

[0026] The present application provides a water-soluble plant wound healing agent and a preparation method. When the healing agent is sprayed on the wound of a tree, the water-soluble lanolin can form a thin film with strong water retention and good air permeability, preventing water evaporation from the xylem of the wound and ensuring the moisture of the wound, thereby achieving rapid wound healing. The mussel mucopolysaccharide can improve the adhesion of the healing agent and prevent the healing agent from being washed away by rain, thereby prolonging the use time of the healing agent. After spraying the healing agent, the sodium naphthalene acetate and the willow branch extract can induce the cambium cells to divide faster, promoting the rapid growth of the cambium, and the tree can heal within 2 months after germination. During the healing period of the tree wound, copper sulfate and mussel mucopolysaccharide can prevent external bacteria from entering the tree wound, achieving the effects of bacteriostasis and sterilization, and avoiding secondary damage caused by pathogenic bacteria.

[0027] The water-soluble plant wound healing agent provided by the present application has good liquid flowability, film-forming property and water retention, and the raw materials are simple and easy to obtain. The preparation process is simple, convenient and efficient, safe, efficient, economical and easy to implement. With a watering can, a small sprayer or the like, the healing of wounds under complex conditions such as high position, large area and large number can be completed, greatly improving the work efficiency and being suitable for large-scale forest farms, enterprises, cooperatives and farm families for production and use.
