AI Technical Summary

Problems solved by technology

Most of the existing selenium-enriched foliar fertilizers and selenium-enriched spray products are selenite or a mixture of selenite and nitrogen, phosphorus, and potassium fertilizers. The surface tension of the aqueous solution is much higher than the interfacial tension of the rice leaf surface. After spraying, it cannot be wetted and adhered to the rice leaf surface, and cannot effectively absorb the selenium-enriched nutrient solution. The rice produced by one-time spraying cannot meet the selenium-enriched rice that meets the requirements

Embodiment 1

[0020] 1. Weigh 5 grams of sodium selenite, 5 grams of nonionic silicone surfactant, and 10 grams of water-soluble laurozone, dissolve them in 900 ml of purified drinking water, and then add purified water to make up to 1000 ml.

[0021] 2. When in use, dilute 1000 ml of selenium-enriched rice foliar spraying agent into 50 kg of water, and spray it on one acre of rice leaves at the heading stage with a sprayer.

[0022] 3. After testing, the selenium content of the rice after spraying was 0.23mg / kg, and that of the control group was 0.07mg / kg.

Embodiment 2

[0024] 1. Weigh 6 grams of sodium selenite, 6 grams of non-ionic silicone surfactant, and 12 grams of water-soluble laurozone, dissolve them in 900 ml of purified drinking water, and then add purified water to make up to 1000 ml.

[0025] 2. When in use, dilute 1000 ml of selenium-enriched rice foliar spraying agent into 50 kg of water, and spray it on one acre of rice leaves at the heading stage with a sprayer.

[0026] 3. After testing, the selenium content of the rice after spraying was 0.23mg / kg, and that of the control group was 0.07mg / kg.

Embodiment 3

[0028] 1. Weigh 8 grams of sodium selenite, 8 grams of non-ionic silicone surfactant, and 16 grams of water-soluble laurozone, dissolve them in 900 ml of purified drinking water, and then add purified water to make up to 1000 ml.

[0029] 2. When in use, dilute 1000 ml of selenium-enriched rice foliar spraying agent into 50 kg of water, and spray it on one acre of rice leaves at the heading stage with a sprayer.

[0030] 3. After testing, the selenium content of the rice after spraying was 0.24mg / kg, and that of the control group was 0.07mg / kg.

Abstract

The invention relates to a paddy rice selenium-rich foliar fertilizer. The paddy rice selenium-rich foliar fertilizer is characterized in that 1L of the paddy rice selenium-rich foliar fertilizer contains 1-10g of sodium selenite, 1-10g of a nonionic organosilicon surfactant, and 2-20g of water-soluble azone. The paddy rice selenium-rich foliar fertilizer allows selenium-rich rice with selenium according with standards to be produced through once spraying on paddy rice foliages of the heading stage. The addition of the nonionic organosilicon surfactant which can reduce the surface tension of an aqueous solution to components of a selenium-rich spraying agent, and the synergism of the plant foliage moistening adhesion promotion and the penetration promotion are used to convert selenium into organic selenium which can be enriched in grains.

Description

technical field [0001] The invention relates to a selenium-enriched leaf fertilizer for rice. Background technique [0002] Selenium is one of the essential trace elements for the human body. The content of selenium in the human body is very small, but it has extremely important physiological functions. It has anti-cancer, anti-cancer, anti-oxidation, protects the body from damage by active oxygen free radicals, and protects the heart. , anti-hepatic necrosis, improve immunity, delay aging and other pharmacological effects. A variety of diseases in the human body, such as high blood pressure, diabetes, and cardiovascular and cerebrovascular diseases, are all related to selenium deficiency. [0003] The distribution of selenium in the natural environment is extremely uneven. The soil in two-thirds of my country is in a state of selenium deficiency, and the crops grown are at a low or deficient level of selenium. Whether the human body is deficient in selenium mainly depends...
