Abstract

The invention provides a multifunctional Se-enriched biological agent for vegetables. The multifunctional Se-enriched biological agent comprises 0.1-0.5 mg/L of Na2SeO3, 0.1-0.2wt% of glycine, and/or 0.1-0.2wt% of alanine and 0.1-0.5wt% of an EM microbial agent. The multifunctional Se-enriched biological agent effectively promotes selenium absorption and increases the selenium content of the vegetables, so that the standards of selenium-enriched vegetables are met; meanwhile, through a synergistic effect among main components (the glycine or/and the alanine, sucrose and the EM microbial agent) of the multifunctional Se-enriched biological agent, the disease resistance of the vegetables is enhanced and the quality of the vegetables is improved.

Description

technical field [0001] The invention relates to a vegetable foliage fertilizer, in particular to a foliage fertilizer for increasing high selenium content in vegetables, improving vegetable quality and enhancing vegetable disease resistance. Background technique [0002] Selenium (Se) is one of the trace elements necessary for living things. It is of great significance to prevent and treat diseases, improve health and prevent aging. It is called "the protective agent of life". In the United States, selenium is regarded as an equally important nutrient with vitamins and β-carotene, and it is a nutrient that must be taken in every day like protein and starch; in 1988, the Chinese Nutrition Society listed selenium as 15 kinds of nutrients. One of the daily dietary nutrients, the recommended intake of selenium is 50-250μg / d. Selenium is unevenly distributed on the earth. There are more than 40 countries and regions that are deficient in selenium. In China, there are as many as ...
