Composite organic selenium nutrient solution, application thereof and sprouting vegetable cultivation method

Abstract

The invention discloses a composite organic selenium nutrient solution, application thereof and a sprouting vegetable cultivation method. The composite organic selenium nutrient solution is formed bymixing selenized carrageenan, urea, monopotassium phosphate and water, the concentration of the selenized carrageenan in the nutrient solution is 5-500 mg / L, the concentration of the urea in the nutrient solution is 2 g / L, and the concentration of the monopotassium phosphate in the nutrient solution is 1 g / L. The composite organic selenium nutrient solution can be applied to the fields of promoting germination of double-low rape seeds and cultivating selenium-rich sprouting vegetables, has a remarkable promoting effect on the germination rate, germination potential, bud length and bud thickness of seed germination, can promote vitamin C accumulation in crops, and can improve the selenium content in the sprouting vegetables.

Description

technical field [0001] The invention belongs to the field of cultivation, and in particular relates to a compound organic selenium nutrient solution and its application and a method for cultivating sprouted vegetables. Background technique [0002] Selenium is a chemical element, which belongs to the essential nutrient elements of animals and the beneficial nutrient elements of plants. Selenium exists in two ways in nature: inorganic selenium and plant active selenium. Inorganic selenium generally refers to sodium selenite and sodium selenate, which are obtained from the by-products of metal mineral deposits; the latter is formed by combining selenium with amino acids through biotransformation, generally in the form of selenomethionine. [0003] At present, studies have proved that selenium has the effects of improving the body's immunity and preventing cancer. At the same time, the selenium intake of the population in most areas of our country is insufficient, and the sele...

Problems solved by technology

[0003] At present, studies have proved that selenium has the effects of improving the body's immunity and preventing cancer. At the same time, the selenium intake of the population in most areas of my country is insufficient, and the selenium content in natural foods is low. It is difficult for people to rely on normal diet to meet their daily selenium requirements. Therefore, eating selenium-enriched foods has become a means of selenium supplementation. However, selenium-enriched foods are currently mainly produced in areas with high selenium content in the land, such as the Badong area of ​​Enshi, and the crops produced are relatively expensive. , while its production is limited
