Abstract

A graphene selenium-rich fertilizer and a preparation method thereof are disclosed. The preparation method of the graphene selenium-rich fertilizer comprises the following steps: (1) directly allowing a protein raw material for later use or performing impurity removal and drying for later use; (2) mixing the protein raw material, selenium mineral powder and graphene oxide, adding the obtained mixture to a nanometer pulverization emulsification system, and adding animal protein hydrolase at the same time for pulverizing and enzyme-hydrolyzing the protein raw material; (3) pulverizing the product obtained from step (2); (4) performing ultrasonic pulverization to the product obtained from step (3); and (5) sending the product obtained from the step (4) to the nanometer pulverization emulsification system, and adding a graphene dispersant to obtain the graphene selenium-rich foliar fertilizer. The invention further comprises a graphene selenium-rich fertilizer. A prospective effect can be achieved through using a little graphene selenium-rich fertilizer. The fixation area between the fertilizer and crops is increased, and a selenium-rich effect of the product is achieved.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a graphene selenium-enriched fertilizer and a preparation method thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body. my country is a country with a large area of ​​selenium deficiency, and about 100 million people in 15 provinces and municipalities are in the selenium deficiency zone. Selenium-deficient adults supplemented with more than 50 micrograms of selenium per day can improve the body's immunity, especially in cancer prevention and suppression. Selenium is a rare element in nature. We mainly supplement the selenium we need through food and drinking water, which require high selenium content in food and drinking water. Therefore, selenium-rich food has become our health food. The use of selenium-rich fertilizers for crops will also increase the selenium content of their products. [0003] Graphene is a...
