Description

Technical Field

[0001] This application relates to the field of pesticides. Specifically, this application relates to the application and methods of oryzanol and naphthaleneacetic acid or their salts in promoting cucumber growth. Background Technology

[0002] Oryzanol is a nucleoside compound produced by the fermentation of the endophytic actinomycete NEAU6 from the Chinese medicinal herb Paris polyphylla. It promotes root growth and germination in crops such as rice and wheat. However, there are few studies reporting on the application of oryzanol in cucumber growth, and further research is needed. Summary of the Invention

[0003] This application aims to at least partially address the technical problems existing in the prior art. To this end, this application proposes the application and method of oryzanol and naphthaleneacetic acid or their salts in promoting cucumber growth. The combined use of oryzanol and naphthaleneacetic acid or their salts can effectively promote cucumber growth, increase the weight and yield of individual cucumbers, and improve cucumber quality, while avoiding undesirable phenomena such as uneven cucumber size, easy bending, and deformed fruits. This method is suitable for widespread application.

[0004] It should be noted that this application is based on the inventor's following discoveries: The inventors of this application discovered in experiments that applying oryzanol to cucumber seedlings could promote growth, but the effect was not significant. To improve the promoting effect, the inventors attempted to combine oryzanol with other growth promoters to obtain a composition that could effectively promote cucumber growth. However, research showed that not all growth promoters combined with oryzanol produced a synergistic effect; on the contrary, some combinations resulted in undesirable phenomena such as uneven cucumber thickness, easy bending, and deformed fruit.

[0005] Naphthaleneacetic acid, also known as α-naphthaleneacetic acid, 1-naphthaleneacetic acid, 1-naphthaleneacetic acid, etc. ISO common name: α-naphthaleneacetic acid; CAS Registry Number: 86-87-3; Chemical name: 1-naphthaleneacetic acid; Molecular formula: C 12 H 10 O2; Relative molecular weight: 186.21; Bioactivity: Plant growth regulation; Melting point: 134.5℃~135.5℃; Vapor pressure (20℃): 1.0×10⁻⁶ - 5 Pa; Solubility (20℃): Slightly soluble in hot water, readily soluble in organic solvents such as acetone, ether, benzene, ethanol, and chloroform; Stability: Stable at pH 3-6, stable to light and heat, but easily decomposes under strong acid and alkali conditions. Common salt forms include sodium naphthaleneacetate, methyl naphthaleneacetate, and ethyl naphthaleneacetate.

[0006] Further research by the inventors revealed that when oryzanol is used in combination with naphthaleneacetic acid or its salts, it not only effectively increases the weight and yield of individual cucumbers but also corrects fruit shape, preventing uneven thickness, bending, and deformed fruits. This combination ultimately enables the cultivation of high-quality cucumbers.

[0007] Therefore, in one aspect of this application, the application of a first active component and a second active component in promoting cucumber growth is proposed. According to an embodiment of this application, the first active component includes oryzanol, and the second active component includes naphthaleneacetic acid or its salt. When oryzanol is used in combination with naphthaleneacetic acid or its salt, it can not only efficiently increase the weight and yield of individual cucumber fruits, but also correct fruit shape, avoiding undesirable phenomena such as uneven cucumber thickness, easy bending, and deformed fruits. Through this combination, high-quality cucumbers can ultimately be cultivated.

[0008] According to embodiments of this application, the mass ratio of the first active component to the second active component is (0.06~16):1, where the second active component contains naphthaleneacetic acid salt, and the mass ratio is based on the naphthaleneacetic acid in the naphthaleneacetic acid salt. In some embodiments, the mass ratio of the first active component to the second active component is 0.0625:1, 0.0667:1, 0.0714:1, 0.0833:1, 0.1:1, 0.125:1, 0.0625:1, 0.2:1, 0.25:1, 0.5:1, 1:1, 2:1, 4:1, 5:1, 6:1, 8:1, 10:1, 12:1, 14:1, 15:1, or 16:1. The combination of oryzanol and naphthaleneacetic acid or its salt in the above proportions can better promote cucumber growth, avoid uneven cucumber size, easy bending, and deformed fruits, thereby improving cucumber yield and quality. The mass ratio of the first active component to the second active component is (0.125~2):1, resulting in better yield and quality of cucumbers.

[0009] According to embodiments of this application, the first active component is provided in solution form, and the concentration of the first active component is 0.03 mg / L to 0.5 mg / L. In some embodiments, the concentration of the first active component is 0.03125 mg / L, 0.04 mg / L, 0.05 mg / L, 0.06 mg / L, 0.0625 mg / L, 0.08 mg / L, 0.10 mg / L, 0.12 mg / L, 0.125 mg / L, 0.14 mg / L, 0.16 mg / L, 0.18 mg / L, 0.20 mg / L, 0.22 mg / L, 0.24 mg / L, 0.25 mg / L, 0.3 mg / L, 0.35 mg / L, 0.4 mg / L, 0.45 mg / L, or 0.5 mg / L. This ensures that the first active ingredient can better promote cucumber growth, while avoiding adverse effects such as uneven cucumber size, easy bending, and deformed fruit caused by excessive dosage. The preferred dosage is 0.06 mg / L to 0.5 mg / L.

[0010] According to embodiments of this application, the second active component is provided in solution form, and the concentration of the second active component is 0.03 mg / L to 0.5 mg / L. In some embodiments, the concentration of the second active component is 0.03125 mg / L, 0.04 mg / L, 0.05 mg / L, 0.06 mg / L, 0.0625 mg / L, 0.08 mg / L, 0.10 mg / L, 0.12 mg / L, 0.125 mg / L, 0.14 mg / L, 0.16 mg / L, 0.18 mg / L, 0.20 mg / L, 0.22 mg / L, 0.24 mg / L, 0.25 mg / L, 0.3 mg / L, 0.35 mg / L, 0.4 mg / L, 0.45 mg / L, or 0.5 mg / L. When the second active component contains naphthaleneacetate, the concentration is based on the mass of naphthaleneacetic acid in the naphthaleneacetate. This allows the second active ingredient to better promote cucumber growth while avoiding adverse effects such as uneven cucumber size, bending, and deformed fruit caused by excessive dosage. The preferred dosage is 0.2 mg / L to 0.5 mg / L.

[0011] In some embodiments, the first active component and the second active component are used in combination at concentrations of 0.03125 mg / L + 0.5 mg / L (ratio 0.0625:1), 0.0625 mg / L + 0.5 mg / L (ratio 0.125:1), 0.125 mg / L + 0.5 mg / L (ratio 0.25:1), 0.25 mg / L + 0.5 mg / L (ratio 0.5:1), 0.5 mg / L + 0.5 mg / L (ratio 1:1); 0.5 mg / L + 0.25 mg / L (ratio 2:1), 0.5 mg / L + 0.125 mg / L (ratio 4:1), 0.5 mg / L + 0.0625 mg / L (ratio 8:1), and 0.5 mg / L + 0.03125 mg / L (ratio 16:1) to better promote cucumber growth.

[0020] In another aspect of this application, a method for promoting cucumber growth is proposed. According to an embodiment of this application, the method includes: applying a first active component and a second active component to the roots of cucumber seedlings; the first active component includes oryzanol, and the second active component includes naphthaleneacetic acid or its salt. The combined use of oryzanol and naphthaleneacetic acid or their salts can effectively promote cucumber growth, increase the weight and yield of individual cucumbers, and improve cucumber quality, while avoiding undesirable phenomena such as uneven cucumber size, easy bending, and deformed fruits.

[0021] According to an embodiment of this application, the mass ratio of the first active component to the second active component is (0.06~16):1. This allows the first and second active components to better exert a synergistic effect, thereby promoting cucumber growth.

This allows the first and second active components to better promote cucumber growth, while avoiding adverse effects such as uneven cucumber thickness, easy bending, and deformed fruit caused by excessive application.

[0024] According to an embodiment of this application, after cucumber seedlings have recovered from transplanting, the first active component and the second active component are applied to the roots of the cucumber seedlings once.

[0025] In this article, the term "plant transplanting acclimatization" refers to the adaptation process of plants after transplanting from a seedling substrate (such as a seedling tray or seedbed) to a field, flowerpot, or other transplanting environment, which typically lasts 1-7 days. Once the plants have recovered to their normal growth state, the first and second active components can be applied.

[0026] According to an embodiment of this application, after the first application of the first and second active components, the first and second active components are applied again after an interval of 8-12 days. This results in a certain improvement in the transverse diameter, yield, and taproot length of cucumbers.

[0027] According to embodiments of this application, the naphthaleneacetate salt includes at least one of sodium naphthaleneacetate, methyl naphthaleneacetate, and ethyl naphthaleneacetate; the first active component and the second active component are provided in the form of a composition; the composition further includes excipients or excipients and solvents, the excipients including at least one of dispersants, emulsifiers, antifreeze agents, wetting agents, disintegrants, and fillers; the dosage form of the composition includes soluble concentrates, suspensions, wettable powders, soluble powders, water-dispersible granules, soluble granules, emulsifiable concentrates, water emulsions, or microemulsions.

[0028] It should be noted that the features and advantages described above regarding the application of the first and second active components in promoting cucumber growth also apply to this method of promoting cucumber growth, and will not be repeated here.

Using naphthaleneacetic acid or its salt as a compound component of oryzanol has a good synergistic effect on increasing cucumber yield, weight and promoting root growth, thus expanding the application of oryzanol in the field of plant growth regulators.

[0030] (2) Oryzanol and naphthaleneacetic acid or their salts are low in toxicity and highly effective, reducing the amount of pesticides used and the amount of pesticide residues on crops. They have a short safety interval and are safe for cucumbers.

[0031] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Detailed Implementation

The above materials are mixed evenly in a mixing tank according to the corresponding proportions to obtain a soluble concentrate with an effective ingredient content of 0.75% oryzanol·sodium naphthaleneacetate.

[0034] Comparative Example 1 In this comparative example, a plant growth regulator composition was prepared according to the method of Example 1, except that oryzanol was not added.

[0035] Comparative Example 2 In this comparative example, a plant growth regulator composition was prepared according to the method of Example 1, except that sodium naphthaleneacetate was not added.

[0036] Comparative Example 3 In this comparative example, a plant growth regulator composition was prepared according to the method of Example 1, except that oryzanol was replaced with chlorpyrifos.

[0037] Comparative Example 4 In this comparative example, a plant growth regulator composition was prepared according to the method of Example 1, except that sodium naphthaleneacetate was replaced with paclobutrazol.

[0038] Test Example 1 The plant growth regulator compositions prepared in Example 1 and Comparative Examples 1-4 were subjected to efficacy tests, as detailed below: 1. Test target: Cucumber (Cucumissativus L.), variety Jinyan 4. Cucumber seeds were purchased from the market.

[0039] 2. Application method: Root irrigation 3. Experimental basis: Refer to NY / T2061.4-2012 "Guidelines for Indoor Bioassay of Pesticides - Plant Growth Regulators" Part 4: Rooting Promotion or Inhibition Test - Cucumber Cotyledon Rooting Method; GB / T17980.141-2004 "Guidelines for Field Efficacy Test of Pesticides (II)" Part 141: Cucumber Growth Regulator Test; NY / T2061.5-2016 "Guidelines for Indoor Bioassay of Pesticides - Plant Growth Regulators" Part 5: Determination of Combined Effects of Mixtures.

[0040] 4. Experimental material cultivation The experimental soil (a mixture of seedling substrate and loess) was quantitatively filled to 4 / 5 of the pots, and the soil was thoroughly moistened using bottom irrigation. Cucumber seeds were evenly sown on the soil surface and then covered with 0.5-1cm of soil. The plants were then moved to a greenhouse (temperature controlled at 25-30℃) for normal cultivation and management. After emergence, the cucumbers were ready for transplanting when they reached the one true leaf stage. After transplanting, bamboo stakes were inserted for the cucumber vines to climb when the cucumbers had more than four leaves. Experiments were conducted after the cucumbers had recovered from transplanting and at 10-day intervals.

[0041] 5. Chemical treatment The sample from Example 1 and the samples from Comparative Examples 1-4 were each diluted 10,000 times. Root irrigation was performed using a graduated cylinder, applying 100 ml of the diluted plant growth regulator composition prepared in Example 1 and Comparative Examples 1-4 to each plant. The treatment was performed once after the cucumber seedlings had established themselves (7 days after transplanting), and then again after 10 days, for a total of two applications. Each treatment was immediately labeled and neatly arranged. The graduated cylinder was rinsed three times each with alcohol and pure water before each use of a different agent. After treatment, the plants were allowed to stand for 24 hours before being transferred to a greenhouse for normal cultivation and management.

[0042] 6. Observation and Result Statistics During the cucumber harvest period, the transverse and longitudinal diameters and single fruit weight of cucumbers were investigated, and yield was measured to calculate the promotion rate and yield increase rate. After harvest, the length of the cucumber taproot was investigated, and its promotion rate was calculated.

[0043] Transverse and longitudinal diameters / single fruit weight: Ten cucumbers from the same batch were randomly selected for each replicate, and their transverse and longitudinal diameters and single fruit weight were measured.

[0044] Yield: The yield of cucumbers harvested cumulatively was measured, and the yield of each replicate was recorded.

[0045] Main root length: For every 3 cucumber plants, carefully dig up the plant by the roots, clean the roots, and record the main root length.

[0046] Investigation on uneven cucumber thickness, easy bending, and deformed fruit: Ten cucumbers from the same batch were randomly selected for each treatment to investigate the number of excessively thick / thin fruits (fruits with a diameter greater than or less than 30% of the average diameter), the number of bent fruits, and the number of deformed fruits.

[0047] Calculation formula

[0048] The indicator in the formula is output.

[0049] The results are shown in Table 1. It can be seen that the combination of oryzanol and sodium naphthaleneacetate of this application can effectively promote cucumber growth, increase yield and single fruit weight, and prevent undesirable phenomena such as uneven cucumber thickness, easy bending, and deformed fruit.

[0053] Test Example 4 The efficacy of the plant growth regulator composition of Example 1 was tested according to the method of Test Example 1, except that in step 5, the drug was applied only once after the cucumber seedlings had recovered from transplanting, and no further applications were made.

[0054] Test Example 5 The efficacy of the plant growth regulator composition of Example 1 was tested according to the method of Test Example 1, except that in step 5, the drug was applied once after the cucumber seedlings had recovered from transplanting, and then applied again after an interval of 5 days, for a total of 2 applications.

[0055] Test Example 6 The efficacy of the plant growth regulator composition of Example 1 was tested according to the method of Test Example 1, except that in step 5, the drug was applied once after the cucumber seedlings had recovered from transplanting, and then applied again after an interval of 15 days, for a total of 2 applications.

[0056] The method described in Test Example 1 was used to investigate the phenomena of uneven cucumber thickness, easy bending, and deformed fruit.

[0057] The results are shown in Table 2. It can be seen that the combination of oryzanol and sodium naphthaleneacetate of this application, with an application amount of 70-130 mL each time, can effectively improve the shape of cucumbers and prevent undesirable phenomena such as uneven thickness, easy bending, and deformed fruits.

E0 – The actual regulating effect of plant growth regulator A and plant growth regulator B after being mixed in the above proportions; E0-E > 10% indicates a synergistic effect; E0-E < -10% indicates an antagonistic effect; and E0-E values ​​between ±10% indicate an additive effect.

[0064] 4. Results and Analysis The results are shown in Table 4. When the mass ratio of oryzanol to sodium naphthaleneacetate is (0.06~16):1, the two can play a synergistic role, effectively increasing cucumber yield and yield rate. The effect is better when the mass ratio is (0.125~2):1.
