A kind of slow-release ozone sol, its preparation method and application

Abstract

The invention provides a slow-release ozone sol, the concentration of each component is: ozone 0.5-30mg / L, sol 0.1-10g / L, stabilizer 0.01-1g / L. The slow-release ozone sol of the present invention can increase the half-life of ozone in tap water by more than 60 times and slowly release ozone. It can not only prevent and control soil-borne diseases of crops safely and efficiently without residue, but also effectively Prevent gaseous ozone from corroding the metal framework of facility agricultural greenhouses. The preparation method of the invention is simple and easy to operate.

Description

Technical field

[0001] The invention relates to a slow-release ozone sol and a preparation method thereof, and the slow-release ozone sol is applied to the prevention and control of crop diseases, especially the prevention and control of soil-borne diseases. Background technique

[0002] With the improvement of living standards, people have higher and higher requirements for food safety, and the issue of pesticide residues has attracted increasing attention. Avoiding pesticides to solve pests and diseases has become a problem in modern agriculture.

[0003] Due to the extensive use of pesticides and other chemical inputs and the continuous cropping of crops for many years, soil-borne diseases are very serious in many parts of our country, and this problem is particularly prominent in agricultural protection areas such as greenhouses and greenhouses.
