Problems solved by technology

The production of selenium-enriched agricultural products requires stable and effective selenium preparations, and most of the existing selenium preparations are multi-element foliar fertilizers that combine selenium with various nutrients needed by plants. Supplementation of other nutrients, ignoring possible antagonistic effects of some of these sulfates on selenium absorption

Embodiment 1

[0007] Embodiment 1: Carry out the test on the wheat Jinnong No. 2 that does not adopt this selenium-enriched plant nutrition regulator, and no selenium content is detected in the wheat grains as the control group; after applying the No. 3 preparation of the selenium-rich plant nutrition regulator, The selenium content in wheat grains is 0.110mg / Kg, and its sodium selenite content of No. 3 preparation is 4%, 5-nitroguaiacol sodium, p-nitrophenol sodium and o-nitrophenol sodium three The content is 0.7%,; after applying No. 4 preparation of selenium-enriched plant nutrition regulator, the selenium content in wheat grain is 0.292mg / Kg, and its sodium selenite content of No. 4 preparation is 8%, 5-nitroguaiac wood The three contents of sodium phenate, p-nitrophenolate sodium and o-nitrophenolate sodium are 0.7%; after applying No. 5 preparation of selenium-enriched plant nutrition regulator, the selenium content in the wheat grain is 0.401mg / Kg, 5 The content of sodium selenite i...

Embodiment 2

[0008] Embodiment 2: Tested on the rice Jindao 9618 that did not adopt this selenium-enriched plant nutrient regulator, the selenium content in the polished rice of the control group was 0.021mg / Kg; The selenium content is 0.199mg / Kg. The content of ammonium selenite in preparation No. 6 was 18%, and the contents of sodium 5-nitroguaiacol, sodium p-nitrophenolate and sodium o-nitrophenolate were 0.7%.

Embodiment 3

[0009] Embodiment 3: In the field test of beans, the selenium content of beans in the control group that did not use the selenium-enriched plant nutrition regulator was 0.005mg / kg; after applying the No. 7 preparation of the selenium-rich plant nutrition regulator, the selenium content of beans was 0.092mg / kg. The sodium selenate content of No. 7 preparation is 8%, p-sodium nitrophenolate, o-nitrophenolate sodium and 2.4-sodium dinitrophenolate three contents are 1%,

Abstract

A Se-enriched plant growth regulator is an aqueous product prepared from the sodium (potassium or ammonium) selenate (or selenite) and the sodium (potassium or ammonium) salt of 5-nitroguaiacol, 2,4-dinitrophenol, or catechol. Its advantages are high chemical and physical stability, and high effect on increasing the content of organoselenium in grains of crops and promoting photosynthesis.

Description

Technical field [0001] The invention belongs to a foliage fertilizer, in particular to a selenium-enriched plant nutrition regulator. Background technique [0002] The research results of modern medicine have confirmed that more than 40 kinds of human diseases are related to long-term insufficient selenium intake, and 72% of my country's areas are internationally recognized selenium-deficient areas. Therefore, it is imperative to develop selenium-enriched agricultural products to supplement selenium through food. The production of selenium-enriched agricultural products requires stable and effective selenium preparations, and most of the existing selenium preparations are multi-element foliar fertilizers that combine selenium with various nutrients needed by plants. Supplement other nutrients, but ignore the antagonism that some sulfates may have on selenium absorption. Studies on plant physiology have clarified that a small amount of sulfate ions in plants can inhibit the...
