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-triticonazole in a wheat flowering stage. The improvement of the wheat quality refers to increase of a fresh weight, a dry weight and a glutenin content of wheat. Aiming at the defects in the prior art, the invention provides the method which is environment-friendly, safe and efficient, has a good sterilization effect, has no adverse effect on the growth of applied crops and can improve the quality of wheat, i.e., rac-triticonazole is used in the wheat flowering period. Experimental results show that when a recommended amount of rac-triticonazole is used in the wheat flowering stage, synthesis of gibberellin in wheat plants and grains can be promoted, synthesis of indoleacetic acid in the wheat plants and grains can be promoted, the filling and maturation of the wheat grains can be promoted, the fresh weight and the dry weight of the wheat grains can be increased, the glutenin synthesis can be promoted, and the rac-triticonazole has low residual quantity in the wheat plants and grains and soil, and has small toxic and side effects on the environment and human bodies.

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...
