Abstract

The invention provides a selenium-rich foliar fertilizer, and a preparation method and an application thereof. The foliar fertilizer comprises specific amounts of a selenium-rich carrot extract liquid, lysine, serine, aspartic acid, potassium dihydrogen phosphate, garlicin, veratridine, a plant growth promoter and a surfactant. Selenium-rich carrots planted in selenium-rich soil are directly used as a biological organic selenium carrier to fully utilize the selenium element in the nature, convert inorganic selenium into free organic selenium which can be directly absorbed by crops and thoroughly avoid environment risks brought by spraying of the inorganic selenium; and the lysine added in the invention improves the utilization rate and the fertilizing effect of the foliar fertilizer, makes the selenium content in every kilogram of the crops reach national standard requirements of the selenium-rich crops, reduces the accumulation of cadmium, lead and other harmful heavy metals in the crops, improves the quality of the crops, and increases the yield of the crops.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a foliar fertilizer capable of providing selenium elements to crops and promoting the absorption of selenium elements by crops, as well as its preparation method and application. Background technique [0002] Selenium is an essential trace element for humans and animals, and an important component to maintain enzyme activity, and participates in important physiological processes of immunity and anti-cancer. Studies have found that a variety of diseases in the human body are related to selenium deficiency, such as anemia, cancer, hepatitis, etc. Therefore, it is very necessary to take an appropriate amount of selenium to maintain human health. From a global perspective, soil selenium deficiency is very common. About 72% of cities and counties in China are in a state of severe selenium deficiency or low selenium. People in selenium-deficient areas eat selenium-rich ...
