Embodiment

[0021] Step 1. Use high-performance liquid chromatography to separate and purify the racemate of Fenconazole into Enantiopak OD chromatographic column, the mobile phase is n-hexane:ethanol 60:40, and the flow rate is 1.0mL / min. Constructs: (S)-(+)-fenazole and (R)-(-)-fenazole;

[0022] Step 2, making the racemate and enantiomer EC of Fenconazole respectively, the formula is: 99.6% Fenconazole of the original drug accounts for 8% (mass percentage), and the anionic emulsifier Nongru 500 accounts for 5%. The non-ionic emulsifier Nongru 601 accounted for 5%, and the solvent was solvent naphtha S-150, accounting for 82%;

[0023] Step 3. Apply the prepared fenconazole racemate and enantiomer EC at the recommended dosage of 60g a.i. / ha to the wheat flowering stage three times, with an interval of 7 days between spraying. 30L / mu dosage dilution;

[0024] Step 4. Take plant, soil and wheat ear samples at 0, 7, 14, 21, 28, and 35 days after application, and collect 1 m of each exper...

Abstract

The invention provides a method for improving wheat quality by using rac-fenazole at the flowering stage of wheat. The improvement of wheat quality refers to the increase of fresh weight, dry weight and gluten content of wheat. The purpose of the present invention is to address the deficiencies of the prior art, to provide an environmentally friendly, safe and efficient method that not only has a good bactericidal effect but also has no adverse effect on the growth of the applied crops but can improve the quality of wheat, that is, using rac ‑Fenconazole. The experimental results show that using the recommended amount of rac-Fenconazole at the flowering stage of wheat can promote the synthesis of gibberellin in wheat plants and grains, promote the synthesis of indole acetic acid in wheat plants and grains, and promote the filling and maturity of wheat grains. Increase the fresh weight and dry weight of wheat grains, promote the synthesis of gluten, and rac-fenazole has low residues in wheat plants, grains and soil, and has little toxic and side effects on the environment and human body.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for improving wheat quality by using rac-fenconazole in the flowering stage of wheat. Background technique [0002] Wheat is one of the world's major food crops and contributes significantly to the global economy. China is the country with the largest wheat production and consumption in the world. High-yielding wheat breeding is essential to meet the demands of a growing world population. In wheat cultivation, powdery mildew, rust, and net spot are common fungal diseases. These diseases not only cause huge economic losses, but also may lead to the reduction of grain quality and the production of toxic metabolites, which can cause vomiting, food refusal and nervous disorders in humans and animals. [0003] Fenconazole, a broad-spectrum triazole fungicide, is widely used in foliar and seed treatments by interfering with ergosterol biosynthesis and inhibi...
