Abstract

An agricultural sterilization nutrient solution is disclosed. The solution is characterized by comprising 0.2-2% by weight of nanometer silver, 15-30% by weight of amino acids, 0.05-0.2% by weight of potassium nitrate, 0.4-5% by weight of potassium dihydrogen phosphate, 0.1-1% by weight of magnesium sulfate, 0.01-0.05% by weight of ethylenediaminetetraacetic acid and 0.1-5% by weight of an auxiliary agent, with the balance being water. The solution contains nanometer silver particles, and therefore a sterilization effect is obvious and the solution can effectively control crop diseases and reduce virus diseases. The solution contains a plurality of other nutrients needed for crop growth, such as the amino acids with the nutrients being supplied for absorption by crops, allows crop growth to be in a system with a water-fertilizer nutrition balance, increases the crop yield and improves crop quality.

Description

technical field [0001] The invention relates to the field of agricultural chemistry, in particular to an agricultural bactericidal nutrient solution. Background technique [0002] Chemical agents are an important means of preventing and controlling crop diseases, and with the change of the environment, the degree of viral diseases in crops has increased. Although the pesticides currently on the market have achieved certain sterilization and insecticidal effects, they still have poor bactericidal effects and resistance. Increase, high residue and other defects. [0003] Nano-silver material has very high temperature physical and chemical properties. It has very excellent performance in many aspects such as electricity, optics and catalysis, and has been widely used in various fields. The bactericidal mechanism of nano-silver fungicides is generally believed to be due to the following effects of silver compounds or silver ions in contact with microorganisms: inhibiting the r...
