Description

Technical Field

[0001] The invention relates to the technical field of plant growth regulation, in particular to a method for regulating the growth of plants parasitized by white wax moths. Background Art

[0002] The white wax worm (Ericerus pela) is a resource insect belonging to the family Ceroplastidae of the order Insecta, commonly known as wax worm, and is one of the three major insects cultivated in China. The white wax worm is a forestry resource insect unique to China. The secretion of its male insect is white wax, which has high economic value, nutritional value, and medicinal value. It is also an important raw material for military, electromechanical, furniture and other manufacturing industries, and is widely used in high-tech and emerging fields.

[0003] During the period of settling, the second-instar male white wax moth settles on the branches of the parasitic plant and sucks the sap of the host plant through the mouth needle with a piercing-sucking mouthpart. These sap contains nutrients such as inorganic salts, amino acids, and polysaccharides. The white wax moth grows by feeding on these nutrients and secretes wax to attach to the branches in the process. Therefore, the nutritional status and growth status of the branches on the parasitic plant directly affect the wax production of the male moth. The physiological condition of the parasitic plant branches under conventional management methods is poor and the nutrient content is relatively low, which causes insufficient nutrient supply to the white wax moth and reduces wax production.

[0004] Therefore, there is a need to find a method for regulating the nutritional status of the branches where male wax moths parasitize plants, so as to improve the nutritional status of the branches and promote the wax production of male wax moths. Summary of the invention

[0005] In view of this, the object of the present invention is to provide a method for regulating the growth of plants parasitized by white wax moths, so as to solve the problem that the branches of plants parasitized by white wax moths are in poor nutritional status, which affects the establishment of white wax moths and wax production.

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

[0007] A method for regulating the growth of plants parasitized by white wax moth, the method comprising:

[0008] (1) Prune the parasitic plants of white wax borer in mid-November, remove diseased and weak branches, reduce the density of branches, and thin out the branches at the top of the main branches. Then apply mixed fertilizer to the parasitic plants after pruning and thinning.

[0009] (2) In early February of the second year, apply promoters and nutrient solution alternately to the parasitic plants, and in late May, prune off half of the leaves on the main branches of the parasitic plants and maintain normal care.

[0010] Furthermore, the parasitic plant of the white wax moth is Ligustrum lucidum.

[0011] The large-leaved Ligustrum lucidum, a parasitic plant of the emerald wax moth, has a strong apical dominance. Through winter pruning, thinning and fertilization, the apical dominance can be broken and the germination and growth of lateral branches can be promoted. Then, nutrient solution is prepared and applied to promote the accumulation of plant nutrients, thereby obtaining more branches rich in nutrients for the growth and development of the emerald wax moth, thereby promoting the wax production of the emerald wax moth.

[0012] Furthermore, the method for regulating the growth of plants parasitized by white wax moth is repeated every year.

[0013] Furthermore, the mixed fertilizer in step (1) is obtained by mixing decomposed cow dung, urea and potassium dihydrogen phosphate in a mass ratio of 10: (0.5-1): (0.1-0.3).

[0014] Further, the preparation method of the accelerator is as follows:

[0015] A: Sodium alginate is added into water to dissolve to prepare a 2wt% sodium alginate solution, methyl tert-butyl ether is added into a 75wt% ethanol solution to dissolve and then added into the sodium alginate solution, stirred for reaction for 4-6 hours, calcium peroxide is added and mixed evenly to obtain a suspension, and then the suspension is slowly injected into a 2wt% calcium chloride solution for gelation to obtain oxygen-releasing particles, and the oxygen-releasing particles are successively put into a 25wt% ethanol solution and clean water for washing and then taken out for use;

[0016] B: Add malonamide to 5wt% hydrochloric acid solution, heat to 75-85℃ and stir to react for 1-4h, cool to room temperature, adjust pH to 5.5-6 and let stand overnight, then add isopropanolamine and mix well, then add oxygen-releasing particles and mix well to obtain the accelerator.

[0017] After the fertilized female adults of the emerald wax moth hibernate, they begin to feed, grow and lay eggs in early March of the following year. Some of the eggs hatch into larvae, which molt and grow into second-instar males. The second-instar males settle on branches and then grow by feeding on sap and secreting wax. Therefore, in order to ensure the wax production of second-instar male emerald wax moths, nutrient solution is applied in early February to promote the accumulation of nutrients such as inorganic salts in the parasitic plant Ligustrum lucidum of the emerald wax moth, promote the fertilized female adults to lay eggs and hatch well, grow into second-instar males, and then settle on branches. They can further grow well through the accumulated inorganic salts and other nutrients, promote the growth and development of the emerald wax moth, and increase wax production.

[0018] The root's absorption efficiency of nutrients determines the plant's growth status and nutrient accumulation, so the present invention prepares a promoter and applies it together with a nutrient solution to improve the root system's absorption efficiency of nutrients in the nutrient solution. Specifically, the oxygen-releasing particles in the promoter use sodium alginate as an embedding layer to embed calcium peroxide. After application, the outer layer of sodium alginate gel has good water absorption and water retention. The retained water continuously acts on the internally embedded calcium peroxide to slowly hydrolyze it and continuously release oxygen, thereby improving the root system's respiration to enhance the root system's active transport of nutrients in the nutrient solution. Further, malonamide improves the root soil's ability to retain nutrients by adjusting the surface charge density of soil particles, and isopropanolamine acts on the root system cell membrane of Ligustrum lucidum, reduces the ordered structure of the cell membrane surface by destroying chemical bonds in the cell membrane, and thereby improves the permeability of the cell membrane, so that nutrients can enter the root system of Ligustrum lucidum more efficiently to promote the accumulation of nutrients in the body of Ligustrum lucidum. The invention continuously treats the Ligustrum lucidum parasitized by the white wax worm through nutrient solution and promoter during its growth period, regulates the growth state of the parasitic plant Ligustrum lucidum to promote the growth and development of the white wax worm, and further increases the wax production.

[0019] Furthermore, in step A, the mass ratio of 2 wt % sodium alginate solution to methyl tert-butyl ether and calcium peroxide is (10-15): (0.1-0.2): (2-3).

[0020] Furthermore, in step B, the mass ratio of malonamide, 5wt% hydrochloric acid solution, isopropanolamine, and oxygen-releasing particles is (0.4-0.8):(10-15):(0.1-0.2):(10-15).

[0021] Furthermore, the nutrient solution comprises the following raw materials in parts by weight:

[0022] 0.05-0.1 parts of potassium sulfate, 0.1-0.2 parts of calcium chloride, 0.1-0.2 parts of magnesium chloride, 0.2-0.3 parts of manganese sulfate, 0.1-0.2 parts of ferrous sulfate, 0.3-0.4 parts of seaweed polysaccharides, 0.3-0.4 parts of sodium humate, and 0.2-0.3 parts of chitosan oligosaccharides.

[0023] Further, the nutrient solution preparation method is as follows:

[0024] Sodium humate, chitosan oligosaccharide and seaweed polysaccharide are added into water and dissolved, and the pH value is adjusted to 6.5-7.5, and then potassium sulfate, calcium chloride, magnesium chloride, manganese sulfate and ferrous sulfate are added and stirred to dissolve to obtain a nutrient solution.

[0025] Furthermore, the method of applying the promoter and the nutrient solution is as follows:

[0026] With the trunk as the center, dig a circular trench with a depth of 15 to 20 cm and a width of 8 to 15 cm at a distance of 20 to 50 cm from the trunk, then evenly apply the accelerator at a rate of 2 to 4 kg per plant to the trench and backfill with soil; apply nutrient solution at a rate of 0.5 to 1 kg per plant 1 to 2 days after the application of the accelerator, and apply the accelerator and nutrient solution once every 2 months in the same way, for a total of 4 applications of the accelerator and nutrient solution.

[0027] Beneficial Effects

[0028] 1. The present invention performs pruning, thinning and fertilizing on the parasitic plants of white wax moth to break the apical dominance and promote the germination and growth of the side branches of the parasitic plants. Then, a nutrient solution with specific components is prepared and applied to improve the growth of branches and promote nutrient accumulation, thereby providing the white wax moth with more suitable fixed branches and more absorbable nutrients, thereby promoting the wax production of the white wax moth.

[0029] 2. The present invention also prepares an accelerator and mixes it with the nutrient solution for application. The accelerator can improve the plant's absorption efficiency of nutrients in the nutrient solution, thereby better regulating and promoting the growth of the plant. DETAILED DESCRIPTION

[0059] Embodiment 4: Method for regulating the growth of plants parasitized by white wax moth

[0060] The method for preparing the nutrient solution used in this embodiment is as follows:

[0061] 0.3 kg of sodium humate, 0.2 kg of chitosan oligosaccharide and 0.3 kg of seaweed polysaccharide were added to 40 kg of water and dissolved, and the pH was adjusted to 7. Then, 0.05 kg of potassium sulfate, 0.1 kg of calcium chloride, 0.1 kg of magnesium chloride, 0.2 kg of manganese sulfate and 0.1 kg of ferrous sulfate were added and stirred to dissolve to obtain a nutrient solution;

[0062] (1) In mid-November of the same year, prune the Ligustrum lucidum parasitized by white wax borers. Specifically, prune the dense branches, crossed branches, overlapping branches, and diseased and insect-infested branches to remove diseased and weak branches and reduce the branch density. Then thin out the top part of the main branches with vigorous growth to weaken the apical dominance and promote the sprouting and growth of lateral branches. Mix rotted cow dung, urea, and potassium dihydrogen phosphate in a mass ratio of 10:0.6:0.2 to obtain a mixed fertilizer, and then apply it at a rate of 4 kg per plant.

[0063] (2) Starting from early February of the second year, the promoter and nutrient solution were applied alternately to the Ligustrum lucidum. Specifically, a circular trench with a depth of about 16 cm and a width of about 10 cm was dug 40 cm away from the trunk, with the trunk as the center. Then, the promoter prepared in Example 1 was evenly applied to the trench at an amount of 3 kg / plant and the soil was backfilled. Two days after the promoter was applied, the nutrient solution was applied at an amount of 0.8 kg / plant. The promoter and nutrient solution were applied again every two months in the same manner, for a total of four applications. In late May, half of the leaves growing on the main branches of the Ligustrum lucidum were thinned out, and then weeding and other maintenance operations were carried out according to conventional methods.

[0064] Experiment 1: Determination of oxygen release performance of oxygen-releasing particles

[0065] 20 g of oxygen-releasing particles were prepared according to the methods of Example 1 and Comparative Example 1 respectively; 3 wide-mouth bottles were taken, 1 L of water was added to each bottle, and then 20 g of oxygen-releasing particles prepared in Example 1 and Comparative Example 1 were put into the bottles respectively, and one bottle was left as a blank control, and then the dissolved oxygen content in each group of bottles was measured at 36 h and 72 h, and the data obtained were shown in Table 1:

[0066]

[0067] It can be seen from Table 1 that the oxygen-releasing particles in the promoter prepared by the present invention can release oxygen stably for a long time, indicating that the prepared promoter can effectively increase the oxygen content of plant roots after application, thereby improving the respiration of plant root cells, promoting the root system's absorption efficiency of nutrients, and promoting good growth of plants to accumulate more nutrients; When preparing the oxygen-releasing particles according to the method of Example 1, methyl tert-butyl ether was added to react with sodium alginate to make it bind to the sodium alginate molecular chain, and the repulsion between the molecular chains during the gelation of sodium alginate was increased by changing the molecular chain structure of sodium alginate, thereby increasing the pore structure of the formed gel ball, so that water molecules can flow better to hydrolyze the calcium peroxide therein, and at the same time, the oxygen released by hydrolysis can be quickly released through the rich pore structure, thereby having better oxygen release performance.

[0068] Experiment 2: Growth regulation experiment of white wax insect parasitized plants

[0069] (1) A growth regulation experiment of Ligustrum lucidum was conducted in a waxworm industrial park in Sanhe Village, Lianghekou Town, Xide County, Sichuan Province. Specifically, a 4-year-old Ligustrum lucidum with a height of about 4.2m, a ground diameter of about 5.4cm, and no pests and diseases was selected as the experimental tree species; the experiment was divided into 10 groups, namely experimental group 1, control groups 1 to 8, and a blank control group, with 10 plants in each group. The growth of each group was regulated according to the following method, as follows:

[0070] Experimental group 1: the accelerator prepared by the preparation method of Example 1 and the adjustment method of Example 4;

[0071] Control groups 1 to 6: using the accelerators prepared in Comparative Examples 1 to 6 and the adjustment method of Example 4 respectively;

[0072] Control group 7: The promoter prepared in Example 1 was used; however, the leaves of Ligustrum lucidum were not thinned in late May, and intact leaves were retained. The remaining steps were the same as those in Example 4;

[0073] Control group 8: No promoter was applied to the growth regulation of Ligustrum lucidum, only nutrient solution was applied, and the remaining regulation steps were the same as those in Example 4;

[0074] Blank control: No promoter was applied, no leaf cutting treatment was performed in late May, and nutrient solution was applied at the same frequency as in Example 4.

[0075] The application amount of the above-mentioned groups of promoters was 3 kg / plant, and the application amount of nutrient solution was 0.8 kg / plant, with a frequency of once every two months, for a total of four times.

[0076] Five plants were randomly selected from each group and the thickness of the one-year-old lateral branches, the proline content, the total sugar content, the crude fiber content and the potassium content in the one-year-old lateral branches of Ligustrum lucidum in the experimental group 1, the control groups 1 to 8 and the blank control group were measured in early July; the average data are shown in Table 2.

[0077] (2) Wax production experiment of white wax moth: Before the plant conditioning experiment began, the wax production of a single white wax moth on unconditioned Ligustrum lucidum was tested. The specific method is as follows:

[0078] After the wax moth entered the pupal stage and stopped secreting wax, branches covered with wax flowers were randomly selected, 50 wax flowers with a length of about 4 cm were peeled off, male insects were picked out and their number was counted, the pure wax flowers were dried at 60℃ for 24 h, and then the wax production of a single insect was calculated to be 0.610 mg.

[0079] After adjusting each group of experimental Ligustrum lucidum according to the above method, 5 plants were randomly selected to measure the wax production of white wax moth on each group of Ligustrum lucidum again, and the average data were shown in Table 2.

[0080]

[0081] According to the data analysis in Table 2:

[0082] (1) The growth regulation of the parasitic plant Ligustrum lucidum according to the method of the present invention can effectively promote plant growth and nutrient accumulation. The one-year-old branches in the experimental group 1 have good growth conditions, and the proline, total sugar, crude fiber and potassium contents are relatively high, thereby providing more branches suitable for the white wax moth to establish a pole and ensuring the supply of nutrients required for the growth and development of the white wax moth during wax production, which is beneficial to promoting the wax production of the white wax moth. The wax production of a single white wax moth in the experimental group 1 can reach 0.679 mg.

[0083] (2) In the control group 1, no methyl tert-butyl ether was added during the preparation of the oxygen-releasing granules in the promoter, resulting in poor oxygen release, which in turn reduced the respiration of the plant roots and led to poor nutrient absorption, thus affecting the wax production. In the control group 2, no malonamide was added during the preparation of the promoter, and in the control group 3, no isopropanolamine was added during the preparation of the promoter. In the control group 2, the poor nutrient adsorption of the soil affected the absorption and accumulation of nutrients by the plants. In the control group 3, the reduced cell permeability led to a reduction in the amount of nutrients entering the plant body, and thus the wax production of each wax moth in the control groups 2 and 3 was reduced.

[0084] (3) In the control group 7, the leaves on the main branches were not cut in half during plant growth regulation. As a result, nutrients gathered to the main branches under transpiration in summer, and the nutrient accumulation in the lateral branches decreased accordingly, which in turn affected the wax production by the wax moth. This indicates that the growth regulation of the wax moth-parasitic plant according to the method of the present invention can promote plant growth through the synergistic effect of each step, so that the branches can efficiently store nutrients and reach a good physiological state for the wax moth to settle and produce wax.

[0085] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
