When rinsing, most chemicals are not resistant to water scouring. If the drug is found to be improper, it can be sprayed with water on the sprayer and sprayed repeatedly on the stems and leaves to wash away the residues remaining on the surface of the cotton plant to reduce the phytotoxicity. For the phytotoxicity caused by the cotton field applied by soil and some herbicides , the soil can be immediately washed and the residual agent can be drenched into the deep layer of the soil.
Fertilizer, generally for the production of leaf venom, leaf edge scorch, plant yellowing and other symptoms of phytotoxicity, increase fertilizer or spray foliar fertilizer, reduce the degree of phytotoxicity, with the new high-fat film mixed together, effectively improve fertilizer The utilization rate of the active ingredients promotes the hair growth and leaves, so that the cotton plants can resume normal growth and development as soon as possible.
Chemical control, due to the phytotoxicity caused by herbicides and plant growth regulators, can be reversely adjusted by spraying plant growth regulators after the phytotoxicity. Spraying Huahua No. 3 can transform the vegetative growth of plants into reproductive nutrition, inhibit the main shoots from becoming mad, and promote flower bud differentiation.
Thin tube. After the phytotoxicity of cotton, timely removal of chlorotic and metamorphic branches and leaves can reduce the penetration and conduction of the agent in the plant; timely cultivation of loose soil, appropriate application of phosphorus and potassium fertilizer can promote root development and enhance the resistance of cotton plants. .
Results indicated that the inactivation of Escherichia coli in artificial wastewater was similar with that in real municipal wastewater. Among three waters, the bactericidal effect of chlorine dioxide was lowest in secondary effluent. The bacteria log inactivation increased by up to threefold when the COD concentration of raw wastewater was decreased by half. An unfavorable COD effect was also observed for the disinfection of secondary effluent. To explain the COD effect on bacteria inactivation, chlorine dioxide residuals were measured with time through each disinfection process. Results from statistical analyses have revealed that, in comparison to the correlations using CT values, the inactivation data can be better correlated with the ratio of COD to ClO2 concentrations. The results of this study would be a useful guide for many municipalities and communities in determining chlorine dioxide dosages for water and Wastewater Disinfection systems.
