Problems solved by technology

At present, the common selenium-enriched fertilizers in the market are mainly the mixture of selenium ore powder and traditional chemical fertilizers. Since natural selenium exists in the state of inorganic compounds, it is not easy for plants to absorb and transform, so it is easy to cause waste of resources and environmental pollution.

Abstract

The invention discloses a selenium-enriched liquid bacterial fertilizer for blueberries and a preparation method of the selenium-enriched liquid bacterial fertilizer. The selenium-enriched liquid bacterial fertilizer contains 5-15 parts of nano-selenium, 8-15 parts of bacillus cereus agent, 8-15 parts of stenotrophomonas maltophilia agent, 4-8 parts of chitosan, 6-10 parts of EDTA, 8-15 parts of amino acid, 8-15 parts of micro-fertilizer and 45-60 parts of water. By using the selenium-enriched liquid bacterial fertilizer, the selenium content of blueberry fruits can be effectively increased, and yield formation and quality improvement can be promoted. The selenium-enriched liquid bacterial fertilizer has the advantages such as remarkable effect, no pollution, high utilization ratio, yieldand quality improvement, low cost and easiness in popularization.

Description

technical field [0001] The invention relates to the fields of blueberry cultivation technology and fertilization, in particular to a blueberry 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 improve...
