Negative ion negative potential organic selenium nutrient solution and preparation method and application thereof

Abstract

The invention relates to the technical field of crop fertilizers, and particularly discloses a negative ion negative potential organic selenium nutrient solution, which is prepared from the following raw materials in parts by weight: 50 to 100 parts of sodium carbonate, 5 to 10 parts of potassium hydroxide, 150 to 220 parts of sodium silicate, 60 to 100 parts of borax, 30 to 50 parts of sugar, 50 to 80 parts of organic selenium, 10 to 25 parts of far infrared tourmaline, 50 to 80 parts of zinc sulfate, 10 to 30 parts of potassium carbonate and 450 to 600 parts of water. The negative ion negative potential organic selenium nutrient solution disclosed by the invention is easily absorbed by plants, and can effectively promote the physiological activity in the plants and coordinate metabolic balance; the growth and development of crops can obtain the best nutritional quality, the selenium content in the crops is obviously improved, and the selenium-enriched effect is achieved; meanwhile, pesticide residues and heavy metals are removed by utilizing the negative potential function of negative ions, so that the crops are healthier and reach the green food standard; the yield of crop fruits can be remarkably increased, the content of medium trace element nutritional ingredients in the fruits is increased, and the quality and flavor are improved.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to an anion negative potential organic selenium nutrient solution and a preparation method and application thereof. Background technique [0002] Selenium is an important nutritional element for the human body. It has the functions of anti-cancer, anti-oxidation, enhancing human immunity, antagonizing harmful heavy metals, regulating vitamin absorption and utilization, regulating protein synthesis, and enhancing reproductive function. Selenium deficiency can easily lead to a decline in human immunity More than 40 kinds of diseases that threaten human health and life are related to human selenium deficiency, such as cancer, cardiovascular disease, liver disease, cataract, pancreas disease and other symptoms. Normally, Chinese adults can take supplementation of more than 25 micrograms of selenium in their daily food for health care, and the intake of selenium in t...

AI Technical Summary

Problems solved by technology

At present, selenium fertilizers mainly use inorganic selenium fertilizers and organic selenium fertilizers. Inorganic selenium fertilizers mainly include selenium mineral powder, sodium selenate, etc., which are absorbed by the roots of plants when applied in the soil. The fertilizer effect is obvious and the price is low, but it has obvious toxicity. It is easy to bring about environmental and safety problems; organic selenium fertilizer is mainly organic selenium liquid fertilizer, which is sprayed on the leaves and absorbed by the leaves of the plants. It is non-toxic and safe, and is easy to use. Sliding down on the surface, causing loss, the leaves have low absorption efficiency of organic selenium fertilizer, resulting in low selenium content in the fruit
