Description

Technical Field

[0001] The present invention relates to the technical field of climbing plants, and particularly to a method for controlling the damage of climbing plants to trees. Background Art

[0002] Climbing plants grow rapidly. After climbing onto trees, they use tendrils, suckers, hooks or other specific attachment organs to climb, quickly twine around the trees and grow, occupying an ecological dominant position and inhibiting the growth of trees. After climbing onto trees, the branches and leaves of climbing plants cover the surface of the trees, blocking sunlight and preventing the trees from obtaining sufficient light for photosynthesis, resulting in slow growth, yellowing or even withering of the leaves of the trees. At the same time, climbing plants compete with the trees for water and nutrients in the soil, leading to poor growth of the trees due to lack of water and fertilizer. In addition, the rapid growth of climbing plants causes their stems to tightly twine around the branches of the trees. As they grow, they may strangle the trees, affecting the normal physiological functions of the trees and even causing deformation or breakage of the branches of the trees. At the same time, the dense branches and leaves of climbing plants are prone to provide hiding places for pests and diseases, increasing the risk of trees being infected with pests and diseases. Therefore, it is necessary to clean the climbing plants on the trees in a timely manner.

[0003] The current main method is to clean the climbing plants on the trees in a timely manner and regularly prune the vines to keep the trees in a healthy state. However, this cannot completely solve this problem. With the continuous growth of climbing plants, the same problem will occur again, and at this time, it is necessary to deal with it again.

[0004] Therefore, the present invention provides a method for controlling the damage of climbing plants to trees, which inhibits the upward growth of climbing plants on the trees and hinders the climbing of climbing plants on the trees, thereby protecting the growth state of the trees. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a method for controlling the damage of climbing plants to trees, which solves the problem that climbing plants are easy to climb onto trees and cause damage to the trees.

[0006] The present invention solves the above technical problems through the following technical means:

[0007] A method for controlling the damage of climbing plants to trees, the method comprising the following steps:

[0008] (1) Clean the climbing plants on the trees in March - April until there are no climbing plants on the tree trunk;

[0009] (2) After the cleaning of the climbing plants is completed, evenly spray a climbing inhibitor on the surface of the tree trunk;

[0010] (3) Spray the surface of the trees that have been sprayed with the climbing inhibitor again. Spray once every month in spring every year, once every month in summer, and once every two months in autumn and winter.

[0011] Furthermore, the preparation method of the climbing inhibitor is as follows:

[0012] S1: Mix polyethylene glycol, methacrylic acid, and p-toluenesulfonic acid evenly, then introduce nitrogen, and stir and react at 110 - 130 °C for 6 - 8 h to obtain modified polyethylene glycol.

[0013] S2: Add the modified polyethylene glycol to the sodium acetate buffer solution, stir evenly to obtain a modified polyethylene glycol solution, then add N-hydroxysuccinimide to the modified polyethylene glycol solution, stir evenly, and then add the o-nitrobenzyl alcohol solution obtained by dissolving o-nitrobenzyl alcohol in methanol. Subsequently, stir for 48 - 50 h, then add titanium dioxide particles, and stir evenly to obtain a mixture.

[0014] S3: Mix ethylenediaminetetraacetic acid and glycerol, then add them to the mixture and stir evenly, and then add papain and stir evenly again to obtain the climbing inhibitor.

[0015] Furthermore, in step S1 of the preparation method of the climbing inhibitor, the mass ratio of polyethylene glycol, methacrylic acid, and p-toluenesulfonic acid is (4 - 5):(2 - 3):(0.1 - 0.12).

[0016] Furthermore, in step S2 of the preparation method of the climbing inhibitor, the mass ratio of the modified polyethylene glycol, N-hydroxysuccinimide, o-nitrobenzyl alcohol, and titanium dioxide particles is (2 - 3):(0.01 - 0.015):(0.2 - 0.4):(0.2 - 0.3).

[0017] Furthermore, in step S2 of the preparation method of the climbing inhibitor, the particle size of the titanium dioxide particles is 100 - 200 nm.

[0018] Furthermore, in step S3 of the preparation method of the climbing inhibitor, the mass ratio of ethylenediaminetetraacetic acid, glycerol, the mixture, and papain is 0.1:5:100:(0.2 - 0.5).

[0019] Modify polyethylene glycol with methacrylic acid to improve the hydrophobicity of polyethylene glycol, which can effectively reduce the contact between water molecules and the surface of the climbing inhibitor, thereby reducing the impact of rain erosion on the climbing inhibitor and enabling the climbing inhibitor on the tree trunk to act on the tree trunk for a longer time. React the modified polyethylene glycol with o-nitrobenzyl alcohol to introduce nitrobenzyl into polyethylene glycol, making the prepared climbing inhibitor photosensitive. When the climbing inhibitor is sprayed on the tree trunk, the titanium dioxide particles in the climbing inhibitor can absorb ultraviolet light. Thus, under the photocatalytic action of the titanium dioxide particles in the climbing inhibitor, the cross-linking bonds of the gel are broken by photocatalysis, reducing the cross-linking density of the climbing inhibitor, further decreasing the hardness of the climbing inhibitor, promoting the climbing inhibitor to embed in the grooves on the tree trunk surface, and enabling the climbing inhibitor to act better on climbing plants. Adsorptive climbing plants can secrete sticky substances (such as polysaccharides or proteins), and through their stickiness, the climbing plants can firmly adhere to the tree trunk surface and climb upward. Therefore, ethylenediaminetetraacetic acid is also added to the climbing inhibitor, which can chelate metal ions such as magnesium ions and calcium ions in the secretions of climbing plants. These metal ions can interact with components such as polysaccharides and proteins in the sticky substances to form stable complexes or cross-linked structures, thereby enhancing the adhesion performance of the sticky substances. Therefore, by chelating these metal ions with ethylenediaminetetraacetic acid, the cross-linked structure of the secretions of climbing plants is destroyed, weakening the adhesion ability of the secretions and inhibiting the upward climbing of climbing plants. At the same time, papain is also added to the climbing inhibitor, which can hydrolyze the peptide bonds in glycoproteins in the secretions and degrade the glycoproteins in the secretions, thereby reducing the adhesion ability of the secretions, decreasing the attachment ability of climbing plants on the tree trunk, making it difficult for them to continue climbing upward, and easily falling off the tree trunk, thus effectively inhibiting the invasion of adsorptive climbing plants on trees. In addition, glycerol in the climbing inhibitor can maintain the stability of papain and prevent the crystallization and precipitation of ethylenediaminetetraacetic acid, thereby enhancing the inhibitory effect of the climbing inhibitor on climbing plants.

[0020] Further, the amount of the climbing inhibitor sprayed in step (2) is 200 - 500 ml / m 2 For the tree trunk, the spraying height is 2 / 3 of the tree trunk height.

[0021] Further, the climbing inhibitor in step (2) should be sprayed on a sunny day.

[0022] Further, the method is applicable to adsorptive climbing plants, specifically Parthenocissus tricuspidata, Hedera nepalensis, Pueraria lobata, Mucuna sempervirens, Parthenocissus quinquefolia, etc.

[0023] Beneficial effects:

[0024] After the climbing inhibitor of the present invention is sprayed on trees, it can effectively inhibit the climbing of adsorptive vine-like plants, avoid the phenomenon that vine-like plants wind around trees and cause the death of trees, and can effectively protect the natural growth of trees. In addition, the climbing inhibitor of the present invention has a simple and safe usage method, will not affect the trees themselves, and can effectively act for a long time, avoiding the situation of multiple cleanings.

[0086] The method for inhibiting climbing plants on trees in this comparative example is the same as that in Example 1.

[0087] Experiment:

[0088] Select 9 tree trunks with a height of 3 ± 0.5 m and a diameter of 6 ± 0.5 cm, evenly spray the climbing inhibitor on the surface of the tree trunks, repeat three times. Among them, the experimental group 1 sprays the climbing inhibitor prepared in Example 1, and the control groups 1-6 spray the climbing inhibitors prepared in Comparative Examples 1-6. The spraying height is 2 m, and the spraying amount is 200 ml / m 2 tree trunk. For the blank control, no spraying is carried out. Then, in May, move the potted plants of the two-year-old climbing plant Parthenocissus quinquefolia trimmed to a height of 1 m to the vicinity of the trees, and twine the vines around the tree trunks. After 60 days, record the climbing heights of different climbing plants on the pine trees in each experimental group. The results are shown in Table 1;

[0089] Select a pine forest seriously invaded by Parthenocissus quinquefolia, select 9 trees with a height of 5 ± 0.5 m and a diameter of 10 ± 2 cm. On March 1, clean the climbing plants on the trees, and then evenly spray the climbing inhibitor on the surface of the tree trunks on sunny days. Among them, the experimental group 1 sprays the climbing inhibitor prepared in Example 1, and the control groups 1-6 spray the climbing inhibitors prepared in Comparative Examples 1-6. Each group repeats the tree experiment 3 times. The spraying amount of the climbing inhibitor is 200 ml / m 2 tree trunk, the spraying height is 3.3 m, spray once every 1 month in spring and summer, and once every two months in autumn and winter. After one year, detect the climbing height of Parthenocissus quinquefolia as shown in Table 2.

[0090] Table 1

[0091] Climbing height (m) Experimental group 1 0.35 Control group 1 0.44 Control group 2 0.48 Control group 3 0.5 Control group 4 0.6 Control group 5 0.54 Control group 6 0.62 Blank control 0.98

[0092] Table 2

[0093] Climbing height in the forest (m) Experimental group 1 0.86 Control group 1 1.27 Control group 2 1.48 Control group 3 1.52 Control group 4 1.96 Control group 5 1.64 Control group 6 2.08 Blank control 3.16

[0094] It can be analyzed from Table 1 and Table 2 that:

[0095] 1. Compared with Experimental Group 1, in Control Group 1, polyethylene glycol was not modified. As a result, the climbing inhibitor prepared was easily washed away by rain after spraying, leading to a decrease in its effect. Therefore, the climbing height in Control Group 1 was higher.

[0096] 2. Compared with Experimental Group 1, in Control Group 2, o-nitrobenzyl alcohol was not added, and the climbing height of Parthenocissus quinquefolia was higher. This is because o-nitrobenzyl alcohol can increase the photosensitivity of polyethylene glycol, reducing its hardness under the action of photodegradation, enabling the climbing plants to better contact with the climbing inhibitor embedded on the tree trunk surface. Therefore, the hardness of the climbing inhibitor in Control Group 2 without o-nitrobenzyl alcohol was higher, and the tightness of contact between the climbing plants and the climbing inhibitor decreased. As a result, the climbing height of Parthenocissus quinquefolia was higher. Compared with Experimental Group 1, in Control Group 3, titanium dioxide particles were added, and the photodegradation rate of the climbing inhibitor was lower, with less reduction in its hardness. Therefore, the climbing height of Parthenocissus quinquefolia was higher.

[0097] 3. Compared with Experimental Group 1, in Control Group 4, ethylenediaminetetraacetic acid was not added, and the prepared climbing inhibitor had a poor ability to destroy the structure of the viscous substances secreted by climbing plants. Therefore, the secretions of the climbing plants in Control Group 4 had better adhesion ability, which was beneficial for the upward climbing of the climbing plants. As a result, the climbing height of Parthenocissus quinquefolia in Control Group 4 was higher. Compared with Experimental Group 1, in Control Group 6, papain was not added, and the climbing height of Parthenocissus quinquefolia was higher. This is because papain can decompose glycoproteins in the substances secreted by Parthenocissus quinquefolia, reducing the attachment ability of the climbing plants to the tree trunk and making it difficult for them to continue climbing upward. Therefore, the climbing height of Parthenocissus quinquefolia in Control Group 6 without papain was higher. Compared with Experimental Group 1, in Control Group 5, glycerol was not added, and the stability of papain in the prepared climbing inhibitor was poor, and ethylenediaminetetraacetic acid was prone to crystallize and precipitate, resulting in a decrease in the effectiveness of the climbing inhibitor. Therefore, the climbing height of Parthenocissus quinquefolia in Control Group 5 was higher.

[0098] 4. In the blank control, no climbing inhibitor was sprayed, and each climbing plant could climb upward well and quickly cover the tree trunk. Moreover, the climbing height of Parthenocissus quinquefolia on the tree without using the climbing inhibitor was 3.16 m after one year, causing relatively serious damage to the tree. However, the climbing height of Parthenocissus quinquefolia in Experimental Group 1 was relatively low, indicating that the climbing inhibitor can effectively inhibit the upward climbing of adsorption-type climbing plants and effectively reduce the damage of adsorption-type climbing plants to trees.
