Problems solved by technology

The main reason for this phenomenon is that although the content of selenium in the soil is high, most of it is in the mineral state, and plants cannot directly absorb and utilize it.

Abstract

The invention relates to the technical field of selenium activation, in particular to a method for applying biological activated oyster powder to activation of selenium in soil. The method comprises the following steps: (1) measuring the selenium content of soil; and (2) applying a selenium activator according to the determined selenium content. According to the invention, the biologically activated oyster powder is used as a main raw material to prepare the selenium activator, and the prepared selenium activator can activate selenium in soil and improve the selenium content of agricultural and sideline products. Besides, a traditional Chinese medicine extract, namely a schisandra chinensis extract, is added into the preparation raw materials of the selenium activator, and the schisandra chinensis extract and the biologically activated oyster powder promote each other and interact with each other, so the selenium element in the soil can be further activated, and the amount of enrichedselenium in agricultural and sideline products is further increased.

Description

technical field [0001] The invention relates to the technical field of selenium activation, in particular to a method for applying biologically activated oyster powder to soil selenium activation. Background technique [0002] Selenium is an essential micronutrient element for the human body. The Chinese Nutrition Society recommends a daily selenium intake of 50-250mg. The human body mainly relies on dietary selenium intake, and selenium-enriched agricultural by-products are an effective way for the human body to supplement selenium. Therefore, selenium-enriched technology has become a hot area of ​​research and development. At present, there are mainly two types of selenium-enriched agricultural and sideline products: natural selenium-enriched and artificial selenium-enriched. Natural selenium-enriched means that plants absorb the available selenium in the soil to reach the selenium-enriched standard, but natural selenium is affected by the natural selenium content in natur...
