Description

Technical Field

[0001] The invention belongs to the technical field of agricultural compositions, and in particular relates to an agricultural composition comprising lecithin. The composition is suitable for agricultural cultivation and planting. Background Art

[0002] As the global ecological environment deteriorates, various environmental stresses are impacting the normal growth of crops to varying degrees. Crops are not always suited to their environment and are often subject to complex and changing stressors. my country, a major agricultural country, faces annual challenges such as drought, salinity, and low temperatures, which severely impact the normal growth, development, and yield of crops.

[0003] Lecithin is a phospholipid substance composed of glycerol, choline, phosphoric acid, and fatty acids. It is commonly found in sources such as egg yolks, animal brains, soybeans, corn, and cottonseed. Lecithin is composed of phosphatidylcholine or cholinephosphoglycerate, with phosphoric acid bound to choline on the triglyceride molecule. Lecithin's molecular structure contains hydrophilic phosphate groups and lipophilic fatty acid groups, making it easily absorbed by plants and enhancing their disease resistance. The hydrophilic groups in lecithin keep plant leaves moist, preventing pathogens and thereby inhibiting their growth and reproduction. Lecithin also has the potential to combat pests and diseases in crops such as vegetables and rice.

[0004] Vitamin B is the general name of B vitamins, which are water-soluble vitamins, including vitamin B1, vitamin B2, vitamin B6, vitamin B 12 Current research results show that the combined use of vitamin E, vitamin C, and vitamin B2 can synergistically exert antioxidant and lipid-regulating effects, effectively capture and eliminate excessive free radicals in the body, maintain the body's dynamic balance of oxidation and antioxidant activity, and protect biological membranes from oxidation and lipid peroxidation damage.

[0005] Vitamin E is a general term for tocopherols, tocotrienols, and their derivatives that exhibit the biological activity of d-α-tocopherol. Vitamin E, as it's commonly referred to, is a mixture of tocopherols, primarily containing eight isomers: α-, β-, γ-, and δ-tocopherols, and their corresponding tocotrienols. All of these share the same vitamin E activity, namely, physiological and antioxidant properties.

[0006] Chitosan oligosaccharides, also known as chitosan oligosaccharides or low-molecular-weight chitosans, are oligosaccharides with a degree of polymerization (DOP) between 2 and 20, obtained by degrading chitosan using specialized enzyme technology. These oligosaccharides can effectively induce plant defense responses, activating the plant's defense system and generating an immune response. Chitosan oligosaccharides possess bactericidal activity, while also achieving both antibacterial and antimicrobial effects. They can penetrate pathogenic bacteria, adsorb anionic cytoplasm, and generate flocculation, disrupting the cells' normal physiological activities and ultimately killing the pathogens. Chitosan exhibits insecticidal activity, but not as strong as chemical pesticides, and therefore should not be used directly as a conventional insecticide.

[0007] Amino acids, as small-molecule proteins, are easily absorbed by crops and can enhance plant disease resistance and improve crop quality. Exogenous amino acids supplement plants with essential amino acids, stimulating and regulating rapid growth, promoting nutrient absorption, enhancing plant metabolism, improving photosynthesis, and accelerating plant growth and reproduction. Gamma-aminobutyric acid, an exogenous amino acid, can effectively promote plant resistance and regulation, and enhance the activity of various enzymes.

[0008] Currently, lecithin is primarily used as a pesticide adjuvant in agricultural cultivation. For example, patent CN109788753A discloses an agricultural adjuvant comprising an oil, a surfactant, and an emulsifier, wherein the adjuvant contains 10 to 40 parts by weight of lecithin. Patent CN110740642A discloses an agrochemical electrolyte composition comprising lecithin and at least one agrochemical active substance. Patent CN110698270A provides a grape foliar fertilizer, its preparation method, application method, and application, comprising polyacrylamide, potassium tripolyphosphate, polyvinyl alcohol, manganese sulfate, calcium lignin sulfonate, zinc sulfate, iron sulfate, boric acid, soybean lecithin, and distilled water.

[0009] During the planting process of crops, they are susceptible to external environmental stress, which, on the one hand, will damage the yield of the crops themselves, and on the other hand, will cause more serious losses to later agricultural management. At the same time, crop growth problems caused by improper use of pesticides occur from time to time, and there are no very effective prevention and control methods. The inventors of this patent application have explored an agricultural composition containing lecithin through in-depth research. The composition has excellent effects in improving the resistance of crops to stress, eliminating the damage of pesticides to crops, and promoting the growth of crops. Moreover, the composition does not appear in known literature, and it is difficult for ordinary technicians in this field to know the beneficial effects of the composition in plant resistance, pest control, growth promotion, etc. Summary of the Invention

[0025] The technical solutions of the present invention are described below with reference to the following embodiments; however, the present invention is not limited to the following embodiments.

[0026] Example 1

[0027] This example provides a field experiment on improving the drought resistance of corn using an agricultural composition containing lecithin. The active ingredients of the agricultural composition are a combination of lecithin, vitamin B, and vitamin E.

[0028] The test corn was "Golden Ear No. 3". The test site was Yongfeng Village, Guanying Town, Anding District, Dingxi City, Gansu Province. The soil type was irrigated black loam soil with uniform fertility levels.

[0029] Lecithin, vitamin B and vitamin E were compounded into a mixed treatment agent in the proportions described in Table 1, and single lecithin, single vitamin B, single vitamin E, adjuvants and clean water were used as control treatment agents. Seed mixing was adopted during the treatment, and the drug-seed mass ratio was 1:10, 1:15 and 1:20. The irrigation method was bottom water + 4 waterings, bottom watering 30 days before sowing, top watering 30 days after sowing, 2 waterings 60 days after sowing, 3 waterings 90 days after sowing, and 4 waterings 120 days after sowing. The sowing method was spot sowing, and the plot area was 36m 2 , row spacing is 60cm, plant spacing is 30cm, and planting density is 65,000 plants / hm 2 Each plot was replicated three times and randomly arranged. After 80% of the corn reached maturity, five-point sampling was used. Five mature corn plants were selected at each point to calculate the 100-kernel weight and final yield. The specific data records are shown in Table 1.

[0037] Lecithin, vitamin B and vitamin E were compounded into a mixed treatment agent according to the ratio described in Table 1, and single lecithin, single vitamin B, single vitamin E, adjuvant and clean water were used as control treatment agents respectively.

[0038] Each culture dish (120 mm in diameter) was padded with a layer of filter paper, and then 6 mL of treatment solution of different concentration combinations (the drop volume of acetochlor and each agent was 1:1) was added. After mixing, 25 germinated wheat seeds with uniform growth (ventral groove facing downward) were added. Each treatment was repeated 3 times. After culturing in the dark in a constant temperature incubator at 28-30°C for 3 days, the wheat sprout length and root length were measured. The specific data recording results are shown in Table 2.

[0039] The calculation method of harm removal effect (%) is as follows:

Each group was treated with the drug for seed soaking (diluted with water and soaked for 12 hours at 20-25℃), applied once during the transplanting seedling stage, once during the jointing and booting stage, and once during the heading and flowering stage. Other treatments were applied according to the regular time.

[0051] During the seedling stage, 20 seeds were sampled at each quincunx-shaped 5-point sampling point, recording the number of seedlings that emerged and calculating the seedling emergence rate. During the transplanting stage, 2 plants were sampled at each quincunx-shaped 5-point sampling point, recording seedling height, root length, and root number.
