Embodiment 1

[0015] Get brown sugar 350g and boil water with 500mL water to obtain brown sugar water, get soybean 200g and boil juice with 500mL water and cool to room temperature to obtain soybean juice. Add brown sugar water and soybean juice, 100g of special bacteria and 5L of clear water into the container, mix and stir well, cover the bottle mouth with 2-3 layers of slightly ventilated gauze, and place it for 40 days after the lid is tightly closed to obtain a mass volume fraction of 91.7g / L's Absorption Enhanced Ferment Broth. Add 27.5 g of sodium selenite to 6 L of the absorption-promoting fermented liquid, and mix to obtain the selenium-enriched fermented liquid foliar fertilizer 1.

[0016] The selenium-enriched fermented liquid foliar fertilizer 1 was diluted 100 times with water, and used for foliar spraying of rice crops, spraying 100 L per mu.

Embodiment 2

[0018] Get brown sugar 350g and boil water with 500mL water to obtain brown sugar water, get soybean 200g and boil juice with 500mL water and cool to room temperature to obtain soybean juice. Add brown sugar water and soybean juice, 100g of special bacteria and 9L of clear water into the container, mix and stir well, cover the bottle mouth with 2-3 layers of slightly ventilated gauze, cover tightly and leave it for 15 days to obtain a mass volume fraction of 59g / L Absorption-enhancing fermented liquid. Add 27.5 g of glutamic acid chelated selenium to 9 L of the absorption-promoting fermented liquid, and mix to obtain the selenium-enriched fermented liquid foliar fertilizer 2.

[0019] The selenium-enriched fermented liquid foliar fertilizer 2 was diluted 100 times with water, and used for foliar spraying of eggplant crops, spraying 100 L per mu.

Embodiment 3

[0021] Get brown sugar 200g and boil water with 500mL water to obtain brown sugar water, get soybean 200g and boil juice with 500mL water and cool to room temperature to obtain soybean juice. Add brown sugar water and soybean juice, 100g of special bacteria and 4L of clear water into the container, mix and stir well, cover the bottle mouth with 2-3 layers of slightly ventilated gauze, cover tightly and leave it for 25 days to obtain a mass volume fraction of 80g / L Absorption-enhancing fermented liquid. Add 20 g of arginine chelated selenium to 5 L of the absorption-promoting fermented liquid, and mix to obtain the selenium-enriched fermented liquid foliar fertilizer 3.

[0022] The selenium-enriched fermented liquid foliar fertilizer 3 was diluted 200 times with water, and used for foliar spraying of corn crops, spraying 80 L per mu.

Abstract

The invention provides a selenium-enriched fermentation liquor foliar fertilizer. The foliar fertilizer is characterized by being prepared by mixing a selenium-containing compound of which the volume fraction by mass is not larger than 5.5g/L and an absorption-enhancing fermentation liquor, wherein the selenium-containing compound is sodium selenite or amino acid chelate selenium. By means of the foliar application of the selenium-enriched fermentation liquor foliar fertilizer, the problems of selenium fixing and loss caused by the application of the selenium compound into soil can be well solved, and a selenium element can be absorbed rapidly and effectively by plants. Meanwhile, inorganic selenium is transformed into organic selenium, so that the selenium content of crops is effectively increased, and very high practicability is achieved.

Description

technical field [0001] The invention belongs to the field of chemical fertilizers, and specifically refers to a selenium-enriched fermented liquid foliar fertilizer and its application. Background technique [0002] Selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-P protein in animals and humans, and plays a role in balancing the redox atmosphere in the body. Studies have proved that selenium has the effect of improving animal immunity, and the research on the effect of selenium on immunity and cancer prevention is a hot issue in this field in the world. 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 minimum recommended value. China is a region rich in selenium resources, but also has a large area of ​​selenium deficiency, ...
