Abstract

The invention discloses a soil selenium element activator, and a preparation method thereof, and belongs to the technical field of soil conditioner. The soil selenium element activator comprises following raw materials: algae skin, diatomite, lime, magnesium hydroxide, humic acid, peat soil, potassium sulfate, zinc sulfate, attapulgite, fulvic acid, plant ash, ferrous chloride, triacontanol, calcium magnesium phosphate fertilizer, and amino acid, and is prepared through steps including mixing, modifying, pelletizing, and drying. According to the preparation method, a reinforcing system composed of triacontanol, calcium magnesium phosphate fertilizer, and amino acid is adopted in preparation of the soil selenium element activator, so that the soil selenium element activator is capable of promoting tea selenium content increasing, tea effective component content increasing, soil pH value increasing, and soil nutrient content increasing.

Description

technical field [0001] The invention belongs to the technical field of soil conditioners, and in particular relates to a soil selenium activator and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. The Chinese Nutrition Society recommends a daily selenium intake of 50-250 mg, but the average daily selenium intake of Chinese adults is only about 36 mg. The source of selenium in the human body mainly depends on dietary intake, and selenium-enriched agricultural by-products are an effective way for the human body to supplement selenium. Therefore, selenium-enriched technology is a hot area of ​​research and development by scientists. Selenium is generally associated with metal sulfides in the crust and exists in the form of rocks. Selenium in rocks ca...
