Abstract

The invention discloses a selenium-rich liquid bacterial fertilizer for roxburgh rose and a preparation method and application thereof. The selenium-rich liquid bacterial fertilizer is prepared from the following components of 5 to 12 parts of nanometer selenium, 5 to 15 parts of bacillus cereus agent, 5 to 15 parts of stenotrophomonas maltophilia agent, 5 to 10 parts of chitosan, 4 to 8 parts ofEDTA (ethylene diamine tetraacetic acid), 4 to 8 parts of amino acid, 5 to 15 parts of trace fertilizer, and 45 to 60 parts of water. The selenium-rich liquid bacterial fertilizer has the advantages that the content of selenium in the roxburgh rose is increased, the output of the roxburgh rose is increased, and the quality of the roxburgh rose is improved; the effect is obvious, the green and pollution-free effects are realized, the utilization rate of fertilizer is high, the output is increased, the quality is improved, the cost is low, the selenium-rich liquid bacterial fertilizer is suitable for being popularized, and the like.

Description

technical field [0001] The invention relates to the field of roxburghii cultivation technology and fertilization, in particular to a roxburghii selenium-enriched liquid bacterial fertilizer and a preparation method and application thereof. Background technique [0002] Selenium is one of the essential trace elements for the human body. Selenium participates in the formation of glutathione peroxidase, which has various special effects such as anti-cancer, anti-cancer, heart protection and anti-aging, anti-oxidation and elimination of free radicals, and improvement of human immunity. Health function. People’s selenium intake is mainly guaranteed by selenium-containing foods. The Chinese Nutrition Society recommends that the selenium intake of Chinese residents be 50-200 μg / day, while the current selenium intake of residents in selenium-deficient areas in my country is only 40-50 μg / day. Therefore, the best way for human body to supplement selenium to prevent disease and improv...
