Description
Technical Field
[0001] This invention relates to the field of agricultural technology, specifically to an anti-burst pod agricultural adhesive and its application method. Background Technology
[0002] Oilseed crops such as rapeseed, soybeans, and peas are prone to pod bursting during harvest. When exposed to severe weather such as storms, snow, and hail, or when struck by the harvester's header, the seeds fall to the ground and become unharvestable, resulting in losses of 15-30% or more in different regions. Rapeseed cultivation is of great importance to my country's food and oil security, and mechanized harvesting is an inevitable direction for the development of rapeseed production. Solving the problem of rapeseed pod bursting can not only increase rapeseed yield but also significantly improve the mechanization of rapeseed production, which has positive implications for the development of my country's rapeseed industry.
[0003] Regarding the problem of rapeseed pod bursting during harvest, there was previously a lack of targeted solutions and research literature in China with large-scale experimental data verification. In practice, some farmers mainly adopted segmented harvesting, that is, cutting down the rapeseed with machinery before it was fully mature, drying it in the field, and finally harvesting and threshing it with a combine harvester. They also sprayed pesticides and chemical agents containing ripening agents and dehydration agents such as diquat, paraquat, and ethephon before harvesting the rapeseed, and changed the shape of the harvester's header to reduce losses.
[0004] Rapeseed plants mature at different times, with the upper pods maturing first and the lower pods maturing later. In current practice, farmers and some agricultural technical guidance institutions adopt early harvesting or segmented harvesting to reduce grain loss. However, early harvesting or segmented harvesting results in higher chlorophyll content in the rapeseed, lower oil content, and affects the quality of the edible oil. Furthermore, two-stage harvesting, compared to a single harvest, adds an extra field operation, increasing production costs.
[0005] The adoption of new harvester headers increases farmers' initial investment, and the loss reduction effect has not been verified through extensive experiments. Furthermore, the use of pesticides such as diquat, paraquat, and ethephon is not only harmful to humans and the environment, but also affects the natural ripening process of rapeseed, thus impacting rapeseed quality.
[0006] This invention uses a purely natural formula, making it natural, green, non-toxic, and harmless, with no harmful effects on humans or the environment. It is simple to use and low-cost. Mixed with water before harvest, it is sprayed via drone, allowing rapeseed to mature naturally and preventing pod bursting and grain loss due to wind, rain, hail, and mechanical harvesting during the ripening period, naturally reducing grain moisture content. Applying this anti-burst pod agricultural adhesive facilitates one-time mechanical harvesting, reducing harvesting costs and increasing yield. Field trials conducted from 2023 to 2026 have verified that it increases rapeseed yield by 6%-30% or more, resulting in an additional income of 60-130 yuan per mu for farmers. Summary of the Invention
[0007] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a crack-resistant agricultural adhesive for rapeseed pods and its application method. Belonging to the field of agricultural technology, this crack-resistant agricultural adhesive is made from 48% natural rosin, 48% pine oil, a byproduct of 2-ethyl-1-hexanol distillation, and 4% emulsified OP-10 by weight. Four weeks before crop harvest, it is sprayed onto the crop using a drone or a ground-based sprayer. The dosage is 100ml of the crack-resistant agricultural adhesive dissolved in 5 liters of water, mixed at room temperature to obtain a diluted crack-resistant agricultural adhesive. A dosage of 5 liters of the diluted crack-resistant agricultural adhesive per acre is applied for spraying. This prevents the cracking of rapeseed pods, ensures pod integrity, and prevents seed loss, effectively improving the crop's resistance to pod cracking. It plays a significant role in reducing seed scattering and increasing yield. It is of great significance for improving the mechanized harvesting of rapeseed and other crops in China and increasing production efficiency.
[0008] To achieve the above technical effects, the following technical solution is adopted: An agricultural adhesive for explosion-proof pods comprises the following components: It is made from 48% natural rosin, 48% pine oil and 2-ethyl-1-hexanol distillate by-products and 4% emulsifier OP-10 by weight.
[0009] Furthermore, the preparation method of the explosion-proof pod agricultural adhesive is as follows: According to the mass ratio, natural rosin, pine oil, 2-ethyl-1-hexanol distillate by-product, and emulsifier OP-10 are poured into a reaction vessel, heated and stirred, and then cooled to separate into layers, thus obtaining the explosion-proof pod agricultural adhesive.
[0010] Furthermore, the preparation process of the 2-ethyl-1-hexanol distillate byproduct is as follows: Pine oil and 2-ethyl-1-hexanol were mixed in a mass ratio of 5:1, placed in a distillation apparatus, heated to 80 degrees Celsius, and distilled for 1.5 hours. The residue was cooled to obtain the pine oil and 2-ethyl-1-hexanol distillate byproduct.
[0011] Furthermore, the heating temperature is 120 degrees Celsius.
[0012] Furthermore, the heating and stirring time is 2 hours.
[0013] Furthermore, the specific application method of the explosion-proof pod agricultural adhesive is as follows: Dissolve the explosion-proof pod agricultural adhesive in water and mix at room temperature to obtain diluted explosion-proof pod agricultural adhesive. Apply the diluted explosion-proof pod agricultural adhesive to the crops using a drone or a ground-mounted sprayer 4 weeks before crop harvest, according to the dosage per acre.
[0014] Furthermore, 100 ml of the explosion-proof pod agricultural adhesive is dissolved in 5 liters of water to obtain diluted explosion-proof pod agricultural adhesive.
[0015] Furthermore, the diluted explosion-proof pod agricultural adhesive is used at a rate of 5 liters per acre.
[0016] Furthermore, the agricultural adhesive for explosion-proof pods is sprayed onto the surface of the crop pods.
[0017] The beneficial effects of this invention are as follows: This invention discloses an anti-burst pod agricultural adhesive and its application method, belonging to the field of agricultural technology. The anti-burst pod agricultural adhesive is made from 48% natural rosin, 48% pine oil, and 2-ethyl-1-hexanol distillate by-products, and 4% emulsified OP-10, in the following mass ratio. Four weeks before crop harvest, it is sprayed onto the crops using a drone or a ground-based sprayer. The dosage is 100ml of the anti-burst pod agricultural adhesive dissolved in 5 liters of water, mixed at room temperature to obtain a diluted anti-burst pod agricultural adhesive. A dosage of 5 liters of the diluted anti-burst pod agricultural adhesive per acre is applied. Within 2 hours, it is absorbed by the surface fibers of the pod, softening the pod fibers and improving the toughness of the pods. Simultaneously, a thin film is formed between the surface cells of the pod, preventing external moisture penetration without affecting the natural respiration of the pods, thus reducing the moisture content of the rapeseed. Preventing the cracking of rapeseed pods, ensuring pod integrity, and preventing seed loss can effectively improve the crop's resistance to pod cracking, playing a crucial role in reducing grain scattering and increasing yield. This is of great significance for the mechanized harvesting of crops such as rapeseed in China, improving production efficiency. Attached Figure Description

[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments of the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, and / or combinations thereof.
[0023] Example 1: It is made from 48% natural rosin, 48% pine oil and 2-ethyl-1-hexanol distillate byproducts, and 4% emulsified OP-10.
[0024] According to the above mass ratio, natural rosin, pine oil, 2-ethyl-1-hexanol distillate by-product, and emulsifier OP-10 are poured into a reaction vessel, heated and stirred, and then cooled to separate into layers, thus obtaining the explosion-proof pod agricultural adhesive.
[0025] Comparative Example 1: The spraying agent is entirely water.
[0026] The following evaluation focuses on the explosion-proof pod agricultural adhesive used in Example 1 and Comparative Example 1: The experimental treatment was carried out by drone spraying 4 weeks before rapeseed harvest, i.e., on April 10, 2025. The water volume was 5L / mu (the dosage was to dissolve 100ml of anti-burst pod agricultural adhesive in 5 liters of water, mix at room temperature to obtain diluted anti-burst pod agricultural adhesive, and spray according to the dosage of 5 liters of diluted anti-burst pod agricultural adhesive per mu). The control group was sprayed by drone spraying 4 weeks before rapeseed harvest, i.e., on April 10, 2025. The water volume was 5L / mu (5 liters of pure water per mu).
[0027] Methods for measuring rapeseed yield in actual fields: like Figure 1 The diagram shows the orientation map of the experimental field for yield measurement. The yield measurement was conducted using a combine harvester for direct harvesting. Each treatment was repeated three times for direct harvesting and data analysis. In Example 1, the anti-explosion pod agricultural adhesive was used for four treatments: control group 1, control group 2, control group 3, and control group 4. In the orientation map of each control group, direct harvesting was repeated three times. In Comparative Example 1, water was used for three treatments: blank group 1, blank group 2, and blank group 3. In the orientation map of each blank group, direct harvesting was repeated three times.
[0028] Yield calculation logic: The area of a single harvest (㎡) is directly measured on-site during rapeseed harvesting, and the actual yield (kg) is weighed on-site. After removing impurities (calculated at 1%) and converting to standard moisture (calculated at 12%), the actual dry yield per mu (kg / mu) is calculated.
[0029] The formula for calculating the actual dry yield per standard mu is as follows: Net dry yield per mu (kg / mu) =
[0030] Precautions for yield measurement: 1. Before harvesting rapeseed, clear away the rapeseed along the boundary to avoid yield measurement errors caused by marginal effects.
[0031] 2. The actual yield measurement adopts random groups, with an indefinite distance gap between the actual yield groups.
[0032] 3. When harvesting, bagging, and weighing rapeseed, avoid placing the bottom of the bag on the ground to prevent it from affecting the accuracy of the data.
[0033] 4. After weighing, the rapeseed moisture content was sampled and tested three times on-site, and the average value was taken as the actual moisture content data.
[0034] 5. Data with obvious anomalies collected during the experiment shall not be used as reference raw data; Harvester model and harvesting process: Kubota Machinery, header width 2.4 meters, one round of harvesting is counted as one direct harvest. Due to the overlapping area when the harvester goes back and forth, the actual measurement of each harvesting area is 4.6 meters.
[0035] Harvest date: May 12, 2025, sunny, 21℃-29℃.
[0036] Rapeseed variety: Shengguang 50 Harvesting area per unit group (3 direct harvests): 4.6 meters × 109.7 meters = 504.62 square meters; Production measurement data: Control group 1: The weighed output (kg) is calculated as follows: 56.1 kg + 53.2 kg + 32.4 kg = 141.7 kg.
[0037] Moisture content: ①26.65% ②26.70% ③25.50% Average: 26.28%.
[0038] Actual standard yield per mu = =155.27 (kg / mu).
[0039] Control group 2: The weighed output is: 58.8kg + 52.7kg + 36.9kg = 148.4kg.
[0040] Moisture content: ①28.6% ②29.9% ③28.8% Average: 29.1%.
[0041] Actual standard yield per mu = =156.39 (kg / mu).
[0042] Control group 3: The weighed output is: 54.4kg + 56.9kg + 51.4kg = 162.7kg.
[0043] Moisture content: ①28.2% ②29.9% ③28.4% Average: 28.8%.
[0044] Actual standard yield per mu = =156.39 (kg / mu).
[0045] Control group 4: The weighed output is: 55.4kg + 58.8kg + 51.2kg = 165.4kg.
[0046] Moisture content: ①28.2% ②29.9% ③28.4% Average: 28.8%.
[0047] Actual standard yield per mu = =156.39 (kg / mu).
[0048] Blank group 1: The weighed output is: 52.8kg + 43.8kg + 56.4kg = 153.0kg.
[0049] Moisture content: ①31.7% ②30.7% ③30.2% Average: 30.87%.
[0050] Actual standard yield per mu = =139.40 (kg / mu).
[0051] Blank group 2: The weighed output is: 57.1kg + 60.5kg + 36.6kg = 154.2kg.
[0052] Moisture content: ①29.9% ②29.9% ③30.0% Average value: 29.93%.
[0053] Actual standard yield per mu = =160.60 (kg / mu).
[0054] Blank group 3: The weighed output is: 54.7kg + 55.4kg + 0.9kg = 111.0kg.
[0055] Moisture content: ①18.8% ②18.7% ③19.8% Average: 19.1%.
[0056] Actual standard yield per mu = =133.47 (kg / mu).
[0057] Data Analysis: Based on the original yield measurement data and the geographical location of the yield measurement groups, the blank group 3 and the control group 1 were located on the edge of the plot, and the original data were significantly lower than the levels of other groups, so they were not of reference significance. Therefore, the average value of the original data of the control groups 2, 3 and 4 was taken as the effective yield data of the control group.
[0058] average yield of control group = =166.69 kg / mu; Average output of the blank group = =150.00 kg / mu; The yield reduction per mu (unit of land area) in the experimental treatment was 166.69 - 150.00 = 16.69 kg / mu. Reduction ratio = =11.1%; A comparison of the average net dry yield per mu (667 square meters) in various yield testing areas, taking Example 1 as an example, shows a significant reduction in loss of 11.1% compared to the blank control. At a market price of 2.7 yuan / jin for rapeseed, this translates to a loss reduction of 90.1 yuan per mu, demonstrating its significant potential for large-scale promotion. This invention can prevent the cracking of rapeseed pods, ensuring pod integrity and preventing seed loss. It effectively improves the crop's resistance to pod cracking and plays a crucial role in reducing grain loss and increasing yield per unit area.
[0059] Based on the experimental results of the above embodiments, this invention utilizes the synergistic effect of natural rosin, pine oil, and 2-ethyl-1-hexanol distillate byproducts to prevent cracking of rapeseed pods, ensuring pod integrity and preventing seed loss, thus effectively improving the crop's resistance to pod cracking. This invention is simple to produce, easy to apply, low in cost, and has significant effects, making it suitable for large-scale use and promotion by farmers, with clear commercial value. Field trials conducted between 2023 and 2026 in Hulunbuir State Farms in Inner Mongolia, Hubei, Sichuan, Chongqing, and Jiangxi showed an average yield increase of approximately 6-15%, with a maximum increase of nearly 40%. The above experiments were conducted by large state-owned enterprises in China, and the experimental results were recognized by the enterprises and local agricultural authorities. Large-scale use of this invention's formula will effectively improve the rapeseed's resistance to pod cracking, playing a crucial role in reducing seed scattering and increasing yield. It is of great significance for the mechanized harvesting of rapeseed in China and improving production efficiency.
[0060] Based on the above-mentioned spraying and yield measurement methods, the verification results obtained from experiments conducted in China are shown in Table 2 below: Table 2 Comparison of validation results obtained from experiments in other regions of China
[0061] In summary, this invention discloses an anti-cracking pod agricultural adhesive and its application method, belonging to the field of agricultural technology.
