Selenium-rich multi-element biological nutrient solution and preparation method

Abstract

The invention discloses a selenium-rich multi-element biological nutrient solution and a preparation method, and belongs to the field of fertilizers. The nutrient solution consists of the following raw materials in parts by weight: 14 to 42 parts of sodium selenite, 18 to 52 parts of active solid-state bacillus subtilis, 7 to 25 parts of zinc sulfate, 7 to 25 parts of ammonium cuprate, 7 to 25 parts of manganese sulfate, 7 to 25 parts of composite rare earth, 4 to 12 parts of boric acid, 1 to 5 parts of chlorophyll, 1 to 3 parts of a stabilizer and 786 to 934 parts of water. After the selenium-rich multi-element biological nutrient solution is applied, the pollution resistance and disease resistance of crops per se are improved, nutrients and trace elements required by the normal growth of the crops are provided, and the crops are favorably prevented from pollution; the quality and yield of the crops are improved; the effect of removing toxicity can be achieved for various crops polluted by heavy metals particularly in a heavy industrial area; the content of various nutrient substances and trace elements in crops and agricultural products is increased, and the nutrient substance and trace element intake of a human body is enriched.

Description

technical field [0001] The invention relates to a multi-element biological nutrient solution, which belongs to the field of fertilizers, in particular to a selenium-enriched multi-element biological nutrient solution and a preparation method thereof. Background technique [0002] Selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-P protein in animals and humans. It plays a role in balancing the redox atmosphere in the body. Selenium has been used as an essential trace element for the human body , studies have proved that it has the effect of improving animal immunity. In the world, the research on the effect of selenium on immunity and cancer prevention is a hot issue in this field. The role of selenium is relatively broad. There are two main principles: first, the composition of antioxidant Enzymes can protect cell membranes from oxidative damage and maintain their permeability; secondly, selenium-P protein can chelate toxic...

Problems solved by technology

Therefore, selenium is called the "king of anti-cancer" among human trace elements by scientists. Selenium can be used as a trace additive for animal feed, and can also be added as trace element fertilizer in plant fertilizers. Selenium products, such as selenium-enriched apples and selenium-enriched tea, usually only increase the selenium content of plants by spraying sodium selenite solution. Can't keep up, affects the absorption rate, and there is no report about special selenium-enriched fertilizer for radish in the prior art

[0003] The existing formula of compound fertilizer products is unreasonable, and the single pursuit of high-nitrogen or high-potassium compound fertilizers is blind, and the utilization rate is low, and some even cause low-quality agricultural products, endangering the health of consumers; the physical properties are not good, and there is much dust , not compressive, caking, inconvenient for storage, transportation and fertilization

Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or water, they are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum, and are easily adsorbed by clay mineral particles, thereby reducing fertilizer efficiency and affecting environmental pollution

Phosphorus and potassium in commonly used compound fertilizers are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum in wastewater, which reduces the utilization rate of fertilizers. Excessive addition not only increases the cost of chemicals, but also easily exceeds the standard of phosphorus content in the effluent
