Heavy metal cadmium composite foliar resistance and control agent and preparation method thereof

[0023] A compound cadmium foliar resistance-controlling agent comprises the following components by mass ratio: 10% soluble silicon, 5% glycerin, 1% surfactant, 0.5% thickener, and 83.5% distilled water.

[0024] Its preparation and use include the following steps:

[0025] ① Weigh soluble silicon, glycerin, surfactant, thickener and distilled water according to the set ratio;

[0026] ② Mix the weighed soluble silicon, glycerin, surfactant, thickener and distilled water evenly to obtain the stock solution of the foliar inhibitor control agent.

[0027] ③Use distilled water to dilute the original solution of the foliar inhibitor and control agent into a diluent, the volume ratio of distilled water and the original solution of the foliage inhibitor and control agent is 500:1, and the pH of the diluted solution of the leaf surface inhibitor and control agent is 7.0, and the prepared The inhibitor dilution solution was sprayed on the rice leaves.
