Selenium supplementation for crops has many benefits.

It is learned from the third Beijing International High-quality Agricultural products Exhibition that selenium supplementation for crops has been accepted by more and more people around the world, because selenium supplementation can improve soil activity, improve crop quality and enhance human immunity.

According to relevant experts, selenium can improve soil consolidation and salinization, promote plants to absorb various nutrients, decompose organic matter in soil, improve soil water and fertilizer conservation capacity, and promote rooting and seedling growth.

Increasing the selenium content of crops can regulate the growth environment of crop roots, benefit the growth of beneficial microorganisms and reproduction, and make the root system of crops developed.

Because selenium is a beneficial nutrient element in plants and animals, studies have shown that it can improve the immunity of animals and plants. Therefore, selenium can be used as a trace additive in animal and plant feed to increase the selenium content of agricultural and sideline products.

At present, selenium has been used as an essential trace element for human body. China is a selenium-deficient country, selenium-deficient areas account for more than 70% of the total land area, and serious selenium-deficient areas account for 30% of the total land area.

However, due to the continuous improvement of agricultural production, over-development of land and other reasons, selenium in 80% of the soil in China is deficient or even does not contain selenium, resulting in a generally low selenium content in the crops produced, which directly affects people's selenium intake. It is reported that the level of selenium in the blood of normal Chinese is much lower than that of Americans.

Selenium supplements can not only improve the quality and competitiveness of agricultural products, but also promote exports, and the physique of most Chinese people need selenium supplements. It should be noted that selenium that exists in nature cannot be absorbed by the human body directly. Only through the absorption and transformation of animals and plants, inorganic selenium can be converted into organic selenium, so that the human body can absorb it. Organic selenium has the effect of anti-cancer and anti-tumor.
