Embodiment 1

[0039] The invention provides a wheat selenium strengthening method, comprising the following steps:

[0040] (1) Prepare a selenium preparation solution; the selenium preparation is a selenoglucose-citric acid auxiliary solution. The selenium preparation solution is a selenoglucose-citric acid auxiliary solution with a concentration of 10 ppm. Sodium selenate solution, selenoglucose solution, selenoglucose-acetic acid auxiliary solution, selenoglucose-hydrochloric acid auxiliary solution were sprayed as control group;

[0041] (2) In fine weather, in the wheat variety Chinese spring clover Yixin period, use spray equipment to spray 20 mL of the selenium preparation solution of the above concentration on each wheat plant as the treatment group, and spray the sodium selenate solution of equal volume and equal pure selenium content as comparison;

[0042] (3) In fine weather, in the wheat variety Chinese spring clover Yixin period, use spray equipment to spray 20 mL of the sel...

Embodiment 2

[0055] The difference between embodiment 2 and embodiment 1 is:

[0056] The invention provides a wheat selenium strengthening method, comprising the following steps:

[0057] In step (1), the selenium preparation is a selenoglucose-citric acid auxiliary solution. The selenium preparation solution is a selenoglucose-citric acid auxiliary solution with a concentration of 10 ppm. Sodium selenate solution, selenoglucose solution, selenoglucose-acetic acid auxiliary solution, selenoglucose-hydrochloric acid auxiliary solution were sprayed as control group;

[0058] In step (2), in fine weather, spray 20mL of the selenium preparation solution of the above-mentioned concentration with spray equipment for each wheat plant in the period of wheat variety Zheng 9023 three leaves and one heart to be the treatment group, and spray the selenic acid of equal volume of pure selenium Sodium solution as control;

[0059] In step (3), in fine weather, spray 20mL of the selenium preparation s...

Embodiment 3

[0070] The invention provides a wheat selenium strengthening method, comprising the following steps:

[0071] (1) Prepare a selenium preparation solution; the selenium preparation is a selenoglucose-citric acid auxiliary solution. The selenium preparation solution is a selenoglucose-citric acid auxiliary solution with a concentration of 10 ppm. Sodium selenate solution, selenoglucose solution, selenoglucose-acetic acid auxiliary solution, selenoglucose-hydrochloric acid auxiliary solution were sprayed as control group;

[0072] (2) in fine weather, spraying 20mL of the selenium preparation solution of the above-mentioned concentration with spray equipment in the wheat variety Clark three-leaf Yixin period is the treatment group, and spraying the sodium selenate solution of the same volume of pure selenium as the control;

[0073] (3) in fine weather, spraying 20mL of the selenium preparation solution of the above-mentioned concentration with spray equipment in the wheat varie...

Abstract

The invention belongs to the field of agricultural planting, and discloses an agronomic strengthening method for improving the selenium content effect of wheat plants.The method is characterized in that a selenium preparation is sprayed in the period of three leaves and one core of wheat in sunny weather, selenium in the selenium preparation is-2 valence, and the selenium preparation is a selenoglucose-citric acid auxiliary solution. The selenoglucose-citric acid additive solution can significantly increase the cumulant of selenium in wheat plants, and proper application can promote the growth of wheat and promote the health of people, livestock and plants.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for strengthening selenium in wheat. Background technique [0002] At present, the application of selenium fertilizer to improve the selenium content of main food crops is the main and effective way to improve the selenium nutritional status of human body. Although there are many kinds of medicaments used for selenium fortification in wheat, the types are mainly concentrated in sodium selenate and selenium. Sodium. Selenium is widely present in various forms of organic and inorganic compounds, showing four valence states (+6 / +4 / 0 / -2). The higher the valence state of selenium, the stronger its oxidativeness and toxicity, and the safety of sodium selenate and sodium selenite is poor. At present, there is a lack of a more efficient, environmentally friendly and safe wheat selenium fortification method. SUMMARY OF THE INVENTION [0003] The purpose of th...
