Embodiment 1

[0016] A high-efficiency concentrated selenium-enriching agent absorbed by plant leaves, containing sodium selenite, glutamic acid, arginine, aspartic acid, brassinolide and gibberellin (composed in a 1:1 ratio) And urea and phosphate; wherein the concentration of selenium is 20%-25% M / V in terms of mass percentage; the concentration of the absorption-promoting agent is 0.1%-1% M / V in terms of mass percentage . The high-efficiency and safe concentrated selenium-enriching agent is diluted with water at 1:500 before use, and then sprayed on the crop corn.

Embodiment 2

[0018] A high-efficiency concentrated selenium-enriching agent absorbed by plant leaves, containing amino acid selenium, arginine, aspartic acid, brassinolide and gibberellin (composed in a 1:1 ratio), urea and phosphoric acid 1%-1%M / V。 Salt; wherein the concentration of selenium in terms of mass percentage is 20%-25%M / V; the concentration of the absorption-promoting agent is 0.1%-1%M / V in terms of mass percentage. The high-efficiency and safe concentrated selenium-enriching agent is diluted with water at 1:500 before use, and then sprayed on the crop corn.

Abstract

The invention relates to a formula and applications of a plant selenium-enriching agent. The selenium-enriching agent includes a high-concentration selenium solution, amino acid nutrients, an absorption promoter, and an auxiliary nutrient that is one of or at least a composition of a plurality of compounds selected from a group consisting of urea, phosphate, sulfate, glucose and caramel. The high-concentration selenium solution is an aqueous solution of a selenium-containing compound, and the concentration of the solution is 20-25% M / V. The absorption promoter is a composition of brassinolide and gibberellins in a ratio of 1:1. The formula can significantly increase the efficiency and yields of selenium-rich crop products, can increase the selenium content of crops, is good in stability and can achieve ideal selenium-rich effects of cereals, vegetables and fruits.

Description

technical field [0001] The invention relates to a formula composition and application of a plant selenium-enriching agent. Background technique [0002] Selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-β protein in animals and humans, and plays a role in balancing the redox atmosphere in the body. Studies have shown that it can improve animal immunity, In the world, the research on the effect of selenium on immunity and cancer prevention is a hot issue in this field. Therefore, selenium can be used as a trace additive for animal feed, and can also be added as trace element fertilizer in plant fertilizers to increase the selenium content of agricultural and sideline products. Selenium has been regarded as an essential trace element for human body. At present, the adult intake recommended by the Chinese Nutrition Society is 50-250 micrograms per day, while the selenium intake in two-thirds of my country is lower than the mi...
