Description

TECHNICAL FIELD

[0001] The present application relates to a large tree nutrient solution conductive composition, a conductive aid and a large tree nutrient solution, belonging to the technical field of garden tree planting. BACKGROUND

[0002] With the development of economy, the improvement of people's living standards, the quality of living environment gradually rises. The transplanting of garden trees is indispensable, but the root system of large trees is damaged during transplanting, and the ability to absorb water and nutrients is reduced. In addition, some ancient and famous trees, with increasing age, have decreased ability to absorb and utilize nutrients, weak photosynthesis, and gradually withered due to the inability to meet the needs of their own survival. Spraying nutrient solution and applying fertilizer have little effect. In view of the above problems, a large number of large tree nutrient solutions have been introduced on the market, which can quickly supplement the nutrients required by the tree body by means of tree injection or bottle insertion. However, for tall and large trees rich in resin, it is difficult to transport the resin into the trunk by means of bag suspension or bottle insertion, and the resin will flow out of the pine and cypress after drilling (such as Figure 1 ), which will block the infusion needle, and the nutrient transport rate in the trunk is low, making it difficult to achieve the purpose of rapid nutrient transport. SUMMARY

[0005] The third object of the present application is to provide a large tree nutrient solution containing a large tree nutrient solution conductive composition or a large tree nutrient solution conductive aid and a base fluid to solve the slow and needle blockage problem of traditional nutrient solution in the process of tree injection and transportation in the prior art.

[0006] In order to achieve the above objects, the technical scheme of the large tree nutrient solution conductive composition in the present application is as follows:

[0007] A large tree nutrient solution conductive composition is made from the following raw materials by weight: ester compound 20-25 parts, polyether modified heptamethyltrisiloxane 15-20 parts, fluorocarbon surfactant 17-20 parts, and anionic surfactant 3-5 parts.

[0008] The beneficial effects of the above technical solution are that the conductive composition for large tree nutrient solution is rich in ester compounds, can quickly dissolve the lipid material secreted by the tree body, greatly reduces the plugging state of the tree body injection needle, and the three surfactants of polyether modified heptamethyltrisiloxane, fluorocarbon surfactant and anionic surfactant cooperate with each other, which can greatly reduce the surface tension of the nutrient solution, and further promote the absorption and transportation of the nutrient solution in the tree body.

[0009] As a further improvement, the ester compound is one or a combination of two or more of ethyl formate, ethyl acetate, and ethyl propionate. Further preferably, the ester compound is ethyl acetate.

[0010] The beneficial effects of the above technical solution are that the ester compound can dissolve many organic substances such as fatty acids, esters, alcohols, etc., can effectively dissolve the resin flowing out of large trees such as pine trees and cypress trees, and can itself increase the cell density of plants and the mass fraction of part of fatty acids, and promote plant growth.

[0011] As a further improvement, the fluorocarbon surfactant is one or a combination of two or more of 2-(trifluoromethyl) acrylic acid and fluorine-containing polyoxyethylene ether. Further preferably, the fluorocarbon surfactant is 2-(trifluoromethyl) acrylic acid.

[0017] The beneficial effects of the above technical solutions are that the conductive aid for large tree nutrient solution is rich in ester compounds, can quickly dissolve the lipid material secreted by the tree body, greatly reduces the plugging state of the tree body injection needle, and the three surfactants, i.e., polyether modified heptamethyltrisiloxane, fluorocarbon surfactant and anionic surfactant, cooperate with each other to greatly reduce the surface tension of the nutrient solution, thereby promoting the absorption and transportation of the nutrient solution in the tree body. The conductive aid for large tree nutrient solution is a clear liquid type lipid-soluble conductive aid, has neutral pH, and has wide application range. Through detection, the conductive aid does not precipitate, crystallize or separate at 0-54 ℃ environment, is convenient for production and storage and transportation, and solves the problems of plugging and difficult absorption and transportation of the traditional nutrient solution tree body injection.

[0018] Further specifically, the mass ratio of the ester compound to water in the conductive aid is 20-25:30-40.

[0019] Specifically, the pH regulator is at least one of 10% mass fraction sodium hydroxide aqueous solution and 10% mass fraction potassium hydroxide aqueous solution.

[0020] Further specifically, the preparation method of the conductive aid for large tree nutrient solution is:

[0022] (2) mixing fluorocarbon surfactant, anionic surfactant and the mother liquor a obtained in step (1) to obtain a solution b, and adjusting the pH to 6.5-7.5 by a pH regulator.

Moreover, the materials selected are common chemical materials and can be conveniently purchased in the market.

[0024] As a further improvement, the mixing condition in step (2) is mixing at 30-45 ℃ until the materials are completely dissolved to be colorless and transparent.

[0025] As a further improvement, mixing is performed at 30-40 ℃ for 30-40 min.

[0026] In order to achieve the above purpose, the technical solution of the large tree nutrient solution in the present application comprises a conductive composition or conductive aid for large tree nutrient solution and a base fluid.

[0027] A large tree nutrient solution comprising a conductive composition or conductive aid for large tree nutrient solution and a base fluid.

[0028] The beneficial effects of the above technical solution are that, through actual application effect verification, the large tree nutrient solution containing the conductive composition and the conductive adjuvant for large tree nutrient solution can not be affected by the resin secreted by the tree body and can be quickly transported into the large tree body, thereby providing an effective means for solving the blockage and difficult absorption and transportation problems of traditional nutrient solution tree body injection.

[0029] Specifically, the base fluid can be different types of tree body nutrient solution or large tree culture solution on the market.

[0030] As a further improvement, 0.2-0.25 parts of the ester compound are added to the conductive composition for large tree nutrient solution per 25-50 parts of the base fluid.

[0031] As a further improvement, the mass ratio of the base fluid to the conductive adjuvant is 25-50:1.

[0032] The beneficial effects of the above technical solution are that, by mixing the base fluid with the conductive adjuvant within the above mass ratio range, the absorption and transportation rate of the large tree nutrient solution can be significantly improved.

[0033] As a further improvement, the tree is a tall resin-rich arbor.

[0034] The beneficial effects of the above technical solution are that, after the resin-rich tall arbor is punched, resin will flow out, and the clear liquid type lipid-soluble conductive adjuvant of the present application can effectively dissolve the resin, promote the absorption and transportation of the nutrient solution, and provide a material basis for quickly protecting and rescuing the tall arbor.
