Abstract
Description
Technical Field
[0001] The invention relates to a synergistic chelated trace element and a preparation and use method thereof. Background Art
[0002] Applied to soil, trace elements in the inorganic state easily react with phosphate, sulfate and organic matter in the soil to form insoluble precipitates, so the utilization rate is low; chelated trace elements combine with organic ligands through chelation reaction to form stable chelates. Chelating agents form ring and cage structures through multiple coordinating atoms in the molecules, which wrap metal ions inside and isolate the metal ions from the reaction with phosphate, sulfate and organic matter. It has the advantage of high utilization rate, and the chelated trace elements are uncharged as a whole.
[0003] Applied to leaf surfaces, there is cuticle on the surface of the leaves, and the composition of the cuticle is mainly fatty acid compounds and pectin polymer compounds, both of which are negatively charged, while the metal ions in trace elements are positively charged. Therefore, the metal ions in the inorganic state are easily adsorbed and fixed by the leaves, thus affecting the utilization rate. The chelated trace elements are not charged, so they can be smoothly absorbed by the plants through the leaves, and the utilization rate is much higher than that of the inorganic state.
[0004] From the above, it can be seen that chelated trace elements applied to the leaves can promote absorption through the leaves smoothly, while applied to the roots mainly prevent them from being fixed and cannot achieve the purpose of promoting absorption. Therefore, although the effect of chelated trace elements applied to the root system is far better than that of the inorganic state, it still has potential.
[0005] Currently, there are no products or methods for applying chelated trace elements to roots to promote root absorption; and the products and methods are required to have broad-spectrum adaptability. Summary of the invention
[0006] The invention provides a synergistic chelated trace element and a preparation and use method thereof, and solves the technical problems of 1) promoting the absorption of the chelated trace element by plant roots; and 2) having stable quality and broad spectrum.
[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: A synergistic chelated trace element comprises chelated trace elements and vitamin E polyethylene glycol succinate; the mass ratio of the chelated trace element to the vitamin E polyethylene glycol succinate is 80-95:5-20.
[0008] The chelated trace elements are EDTA chelated trace elements, DTPA chelated trace elements, IDHA chelated trace elements, EDDHA chelated trace elements and HBED chelated trace elements.
[0009] The pH of trace elements in synergistic chelation is 3-6.
[0010] A pH buffer is also included, wherein the pH of the pH buffer is 3-6.
[0011] A method for preparing synergistic chelated trace elements, comprising mixing chelated trace elements and vitamin E polyethylene glycol succinate to obtain synergistic chelated trace elements; or The chelated trace elements and vitamin E polyethylene glycol succinate are dissolved in water to obtain the enhanced chelated trace elements; The mass ratio of trace elements, vitamin E polyethylene glycol succinate and water in the chelate is 4-12:0.4-4:84-94.75.
[0012] It also includes adjusting the pH to 3-6.
[0013] The trace elements in the synergistic chelate are diluted 100 to 1000 times, and the concentration of vitamin E polyethylene glycol succinate after dilution is greater than or equal to 0.02%, and the pH after dilution is 6.0 to 6.9.
[0014] The invention has the following beneficial technical effects: 1) This application can further improve the effect of applying trace elements in chelation to roots by adding vitamin E polyethylene glycol succinate and controlling the pH of the trace elements in the synergistic chelation.
[0015] 2) This application has a better effect when used under slightly acidic conditions. By adding a pH buffer, it can meet the impact of different water pH values in different places, especially in areas with alkaline water. In addition, this application is diluted before use, and the dilution multiple is large, which may make the pH slightly alkaline, affecting the use effect. The addition of pH buffer makes the product have a broad spectrum of adaptability, quality issues, and is conducive to promotion. DETAILED DESCRIPTION

[0045] The beneficial effects of the present invention are further illustrated below in conjunction with test data: Experiment 1 1.1 Experimental location: Gansu Smart Agriculture Engineering Technology Research Center.
[0046] 1.2 Experimental test: calcium content (mg / g) and magnesium content (mg / g).
[0047] 1.3 Test materials: Comparison 1 (EDTA-2NaCa), Comparison 2 (IDHA-2NaMg), Example 1 and Example 3.
[0048] 1.4 Experimental method: A hydroponic experiment was carried out on pakchoi, and the nutrient solutions were diluted comparison 1 (EDTA-2NaCa), comparison 2 (IDHA-2NaMg), example 1 and example 3, respectively. Table 1 was diluted 350 times, and the pH values of the dilutions were 6.0, 6.5, 7.0 and 7.5, respectively; Table 2 was diluted 400 times, and the pH values of the dilutions were 6.0, 6.5, 7.0 and 7.5, respectively; Table 3 was diluted 450 times, and the pH values of the dilutions were 6.0, 6.5, 7.0 and 7.5, respectively; Table 4 was diluted 500 times, and the pH values of the dilutions were 6.0, 6.5, 7.0 and 7.5, respectively.
[0049] After the pakchoi took root in hydroponics, the culture medium was replaced with the test treatment, and the culture medium was replaced every 7 days, for a total of 2 changes. On the fifteenth day after the first culture medium was changed, the calcium content (mg / g) and magnesium content (mg / g) were tested. The test was carried out by drying the pakchoi in a vacuum oven at 60°C, then crushing it and testing it.
[0050] Detection method: flame atomic absorption spectrometry.
[0051] 1.5 Results and Analysis Diluted 350 times, calcium content (mg / g), abbreviated as calcium (mg / g) in the table, and magnesium content (mg / g), abbreviated as magnesium (mg / g) in the table are shown in Table 1 Table 1
[0052] Diluted 400 times, calcium content (mg / g), abbreviated as calcium (mg / g) in the table, and magnesium content (mg / g), abbreviated as magnesium (mg / g) in the table are shown in Table 2 Table 2
[0053] Diluted 450 times, calcium content (mg / g), abbreviated as calcium (mg / g) in the table, and magnesium content (mg / g), abbreviated as magnesium (mg / g) in the table are shown in Table 3 Table 3
[0054] Diluted 500 times, calcium content (mg / g), abbreviated as calcium (mg / g) in the table, and magnesium content (mg / g), abbreviated as magnesium (mg / g) in the table are shown in Table 4 Table 4
[0055] Note: Among them, only the calcium content (mg / g) was detected in comparison 1 (EDTA-2NaCa) and Example 1; only the magnesium content (mg / g) was detected in comparison 2 (IDHA-2NaMg) and Example 3.
[0056] It can be seen from the data in Table 1, Table 2, Table 3 and Table 4 that the use of Comparison 1 (EDTA-2NaCa) and Blank 2 (EDTA-2NaMg) is basically not affected by pH, while Examples 1 and 2 with the addition of vitamin E polyethylene glycol succinate are affected by pH. In terms of data, at Ph 6.0 and 6.5, the absorption of calcium and magnesium by the pakchoi in Examples 1 and 3 with the addition of vitamin E polyethylene glycol succinate exceeds that of Comparison 1 and Comparison 2, and the effect is obvious. At pH 7.0 and 7.5, the absorption of calcium and magnesium by the pakchoi in Examples 1 and 3 with the addition of vitamin E polyethylene glycol succinate is basically equivalent to that of Comparison 1 and Comparison 2.
[0057] The use of this application is greatly affected by pH, and the water quality in different places is different, some water is alkaline, and this application is diluted and used, and the dilution multiple is very large. Therefore, if alkaline water is used for dilution, the pH may be greater than or equal to 7 during use, thereby affecting the use effect. The addition of a pH buffer, and the pH buffer buffering pH is 3 to 6, can reduce the impact of alkaline water quality on pH, thereby ensuring the use effect.
[0058] Experiment 2 1.1 Test location: Huishi Town, Huining County, Baiyin City, Gansu Province. Test variety: sesame.
[0059] 1.2 Experimental testing: Statistical analysis of sesame yield (kg / mu) and oil yield (%).
[0060] 1.3 Test materials: Comparison 2 (IDHA-2NaMg), Example 3 and Example 4.
[0061] 1.4 Experimental methods: 2 mu of sesame was divided into 6 plots, each plot was 200 square meters, and isolation belts were set between the plots. The plots were randomly corresponding to the treatments. The sesame was subjected to drip irrigation treatment three times, and each test sample was treated with 1 portion each time. Each test sample weighed 200 g. The method of use was as follows: 1 portion of the sample was diluted 1000 times with water and drip irrigated with water. The interval between two adjacent treatments was 25 days. Example 3 was divided into two treatments, one was used after dilution and pH measurement, and the pH was 7.01-7.11, recorded as Example 3-1; the other was used after dilution and pH was adjusted to 6.45-6.55, recorded as Example 3-2; wherein the pH of Comparison 2 (IDHA-2NaMg) after dilution was 7.04-7.14, and the pH of Example 4 after dilution was 6.45-6.55.
[0062] The pH value is a range because the test was conducted three times and the pH after each dilution could not be completely consistent due to the influence of water quality.
[0063] Yield statistics: Yield is measured by weighing method; oil yield is measured by traditional pressing method, which is equal to the mass of sesame oil divided by the mass of sesame on dry basis.
[0064] The water quality in Huining County is alkaline, and the pH of the natural water used for dilution in this test is 7.48.
[0065] Except for the experimental treatment, other operations were the same in this experiment.
[0066] 2 Results and analysis The yield (kg / mu) and oil yield (%, on a dry basis) of sesame are shown in Table 5. Table 5
[0067] It can be seen from Table 5 that adding vitamin E polyethylene glycol succinate to the chelated trace elements can further enhance the use effect of the chelated trace elements when used in a slightly acidic environment. It is recommended to use it under slightly acidic conditions.
[0068] From the comparison of the data of Example 3-1 and Example 4, it can be seen that adding a pH buffer to the trace elements in the synergistic chelating agent can increase the quality stability of the product, especially when it is applied in areas with alkaline water quality.
