Selenium-rich nutrient solution

Abstract

The invention provides selenium-rich nutrient solution, which is characterized by being prepared by the following raw materials in parts by weight: 25-28 parts of sodium selenite, 12-15 parts of ammonium sulfate, 13-15 parts of anhydrous boric acid, 15-20 parts of potassium sulfate, 5-10 parts of clay, 10-15 parts of diammonium phosphate, 2-5 parts of fulvic acid, 0.5-1 part of zinc chloride, and the like. The nutrient solution not only contains major elements required for the growth of carambola, and is rich in trace elements, organic acid and microorganism flora, but also is fed with medicament with efficacies of sterilization and prevention, so as to play a role in insect disease prevention while spraying.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a selenium-enriched nutrient solution. 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 substances such as heavy metals and reduce the toxicity of toxic substances. Therefore, selenium is called the "kin...

In agriculture, biological control is adopted, that is, natural enemies are stocked for natural control, but a large amount of labor is required for field operations; or insecticidal lamps are used for physical control, but the cost of insecticidal lamps is relatively high; or chemical pesticides are used for spraying, although it will Reasonable choice of dosage, but there is still some damage to the environment, and at the same time, it will harm beneficial insects and other animals while spraying
