Description

Technical Field

[0001] This invention relates to the field of pesticides, specifically to a taurine derivative as a plant growth regulator and its application. Background Technology

[0002] Plant growth regulators play a vital role in agricultural production, specifically in the following aspects: 1) Promoting plant growth: Plant growth regulators can stimulate plant growth, promote root growth and branching, increase seedling biomass and leaf area, thereby improving photosynthesis and yield. 2) Enhancing plant stress resistance: Plant growth regulators can enhance plant stress resistance, improve tolerance to environmental stresses (such as drought, high temperature, salinity, etc.), and reduce losses caused by adverse conditions in production. 3) Regulating plant growth stages: Plant growth regulators can regulate the vegetative and reproductive growth stages of plants, promote flower bud differentiation, flowering, and fruiting, and improve crop yield and quality. 4) Controlling plant shape: Plant growth regulators can control plant height and branch elongation, giving plants a more compact growth form, facilitating management, harvesting, and mechanized harvesting. 5) Improving agricultural product quality: Plant growth regulators can improve the quality of agricultural products, such as enhancing fruit color, sugar content, and taste, extending fruit shelf life, and increasing the commercial value of agricultural products.

[0003] Fertilizer synergists are products used to improve plant utilization of fertilizers. They have many beneficial effects in agriculture and horticulture, which are generally considered to include the following: 1) Improving fertilizer utilization: Fertilizer synergists can promote the absorption and utilization of fertilizers by plants, increasing fertilizer utilization efficiency. They can improve soil structure and change soil pH, thereby improving the absorption of nutrients in fertilizers by plants. 2) Reducing fertilizer waste: Synergists can reduce fertilizer loss and volatilization, lowering the risk of environmental pollution. This helps protect soil and water resources and reduces dependence on chemical fertilizers. 3) Promoting plant growth: Synergists contain plant growth regulators that can stimulate plant growth and development. They can increase chlorophyll content, enhance photosynthesis, and promote root growth, thereby improving plant yield and quality. 4) Increasing plant stress resistance: Some synergists contain beneficial microorganisms that can improve plants' resistance to diseases, pests, and adverse conditions. They can increase the plant's own immunity and improve the plant's adaptability to stressful environments. 5) Promoting Soil Health: Fertilizer synergists can improve the physical properties and biological activity of soil, increase soil fertility, and retain moisture. They help improve soil quality, reduce soil degradation, and promote the decomposition and cycling of organic matter. It is evident that some of the functions of fertilizer synergists are the same as those of plant growth regulators, which have a natural advantage as fertilizer synergists. The selection of appropriate fertilizer synergists should be based on the specific needs of the crop and soil conditions, avoiding inappropriate or excessive use. Furthermore, synergists are not a panacea; other agricultural management measures, such as rational fertilization, irrigation, and pest and disease control, should also be considered in conjunction to ensure their synergistic effect.

[0004] Because of the vast variety of products in agricultural production, existing plant growth regulators cannot meet the efficiency improvement needs of all crop production. Therefore, it is of great significance to develop new plant growth regulators for use in the fertilizer field.

[0005] A search of existing technologies revealed no literature reporting the use of taurine derivatives as plant growth regulators or fertilizer synergists. The applicant of this invention has discovered that taurine derivatives, as plant growth regulators, can also be used as fertilizer synergists in combination with fertilizers to improve fertilizer utilization efficiency, reduce the frequency and labor costs of pesticide application for pest and disease control, increase agricultural yield and quality, and enhance economic benefits. Furthermore, this approach is environmentally friendly and aligns with sustainable development requirements. Summary of the Invention

[0006] To address the issue that existing plant growth regulators cannot meet the efficiency enhancement needs of all crop production, this invention provides a novel plant growth regulator and its application in fertilizer enhancement. When used in conjunction with fertilizers, this plant growth regulator can effectively increase crop yield and improve crop quality.

[0039] In summary, the taurine derivatives of this invention have certain growth-regulating effects on plants. In particular, the treatments with taurine derivatives in samples 3, 6, and 14 of this invention showed significantly better activity in promoting the growth of wheat roots and shoots than the blank control and positive control. This indicates that the relevant taurine derivatives have plant growth-regulating activity as fertilizer synergists, and are superior to the currently commercially available plant growth regulator indoleacetic acid.

[0040] Example 2: Wheat Yield Measurement

[0041] The experiment was conducted from March to June 2022 at the farm of the Xuchang Agricultural Science Research Institute in Jian'an District, Xuchang City, Henan Province. The tested soil was brown soil with a heavy loam texture. The experimental site was located in a warm temperate semi-arid region with deep soil layers and good water retention. Before wheat sowing, the land was prepared by rotary tillage and conventional leveling with a row width of 20 cm. The seeding rate was 150 kg / hm². 2 Sowing was carried out on March 17th, and harvesting on June 12th. Irrigation was applied once after sowing and once at the jointing stage. The experiment included six treatments. The nitrogen, phosphorus, and potassium fertilizer application rate for the control plot was 180 kg / hm². 2 Urea, 100 kg / hm 2 P2O5 and 60 kg / hm 2 K2O; In the positive control plot, the application rates of nitrogen, phosphorus, and potassium fertilizers were increased by 75 g / hm² to those in the blank control plot. 2 Treatment 1 plot was supplemented with treatment 3 (25 g / hm²) based on the nitrogen, phosphorus, and potassium fertilizer application rates of the control plot. 2 Treatment 2 plots were treated with an additional 50 g / hm² of nitrogen, phosphorus, and potassium fertilizer applied, based on the nitrogen, phosphorus, and potassium fertilizer application rates of the control plots. 2 Treatment 3 plots were treated with 75 g / hm² of nitrogen, phosphorus, and potassium fertilizers, in addition to the nitrogen, phosphorus, and potassium fertilizer application rates of the control plots. 2 Three replicates, completely randomized block design, cell area 100m² 2 Apply the first spray during the early heading stage of wheat, followed by a second spray 7 days later. Other management practices should follow the local wheat field management guidelines.

[0042] During wheat harvest, a 1m measurement is taken at the center of each plot. 2 The number of ears was determined by area; 100 ears were randomly selected to investigate the number of grains per ear; 1m of land was harvested. 2 The grains were naturally air-dried, and their moisture content was measured. The yield per hectare was then converted into the yield per thousand grains.

[0045] In summary, the taurine derivative treatment 2 of sample 3 in this invention showed significantly better wheat yield data than the blank control and positive control, indicating that the taurine derivative of sample 3 possesses plant growth regulating activity as a fertilizer synergist, and is superior to the currently commercially available plant growth regulator indoleacetic acid. When used in combination with fertilizers, the taurine derivative of this invention can effectively increase fertilizer utilization efficiency, promote crop growth, and improve crop yield, exhibiting excellent field activity and making it effectively applicable in the field of crop production.
