The use of cyclohexylamine in agricultural chemicals and its effect on crop growth

Abstract

Cyclohexylamine (CHA), as an important organic amine compound, is widely used in agricultural chemicals. This article reviews the use of cyclohexylamine in agricultural chemicals, including its application in pesticides, fertilizers and plant growth regulators, and analyzes in detail the effect of cyclohexylamine on crop growth. Through specific application cases and experimental data, it aims to provide scientific basis and technical support for the research, development and application of agricultural chemicals.

1. Introduction

Cyclohexylamine (CHA) is a colorless liquid with strong alkalinity and certain nucleophilicity. These properties make it exhibit significant functionality in agricultural chemicals. Cyclohexylamine is increasingly used in pesticides, fertilizers and plant growth regulators, playing an important role in improving crop yield and quality. This article will systematically review the application of cyclohexylamine in agricultural chemicals and explore its impact on crop growth.

3. Application of cyclohexylamine in agricultural chemicals

3.1 Pesticides

The application of cyclohexylamine in pesticides mainly focuses on the preparation of fungicides, insecticides and herbicides and the addition of synergists.

3.1.1 Fungicides

Cyclohexylamine can react with different organic acids to generate efficient bactericides and improve the bactericidal effect. For example, the reaction between cyclohexylamine and carbendazim produces cyclohexylamine and carbendazim, which has a broad-spectrum bactericidal effect.

Table 1 shows the application of cyclohexylamine in fungicides.

3.1.2 Pesticides

Cyclohexylamine can react with different organic compounds to generate highly effective pesticides and improve the insecticidal effect. For example, the reaction between cyclohexylamine and pyrethroids produces cyclohexylamine pyrethroids, which have broad-spectrum insecticidal effects.

Table 2 shows the application of cyclohexylamine in pesticides.

3.1.3 Herbicides

Cyclohexylamine can react with different organic acids to generate highly effective herbicides and improve herbicidal effects. For example, the reaction between cyclohexylamine and glyphosate produces cyclohexylamine-glyphosate, which has a broad spectrum of herbicidal effects.

Table 3 shows the application of cyclohexylamine in herbicides.

3.2 Fertilizer

The application of cyclohexylamine in fertilizers mainly focuses on improving the stability and slow-release effect of fertilizers.

3.2.1 Modification of urea

Cyclohexylamine can react with urea to generate slow-release urea, improving the stability and utilization of fertilizers. For example, the cyclohexylamine-urea produced by the reaction of cyclohexylamine and urea has a sustained-release effect, extending the effectiveness of the fertilizer.

Table 4 shows the application of cyclohexylamine in urea modification.

3.3 Plant growth regulator

The application of cyclohexylamine in plant growth regulators mainly focuses on promoting plant growth and increasing crop yields.

3.3.1 Promote plant growth

Cyclohexylamine can react with different plant hormones to generate efficient plant growth regulators and promote plantgrow. For example, cyclohexylamine and gibberellin produced by the reaction of cyclohexylamine and gibberellin have significant growth-promoting effects.

Table 5 shows the application of cyclohexylamine in plant growth regulators.

4. The effect of cyclohexylamine on crop growth

4.1 Promote root development

Cyclohexylamine can promote the development and expansion of root systems by regulating the growth of plant roots. Research shows that crops treated with cyclohexylamine have more developed root systems and greater ability to absorb nutrients.

Table 6 shows the effect of cyclohexylamine on crop root development.

4.2 Improve photosynthesis efficiency

Cyclohexylamine can improve photosynthesis efficiency by regulating the opening and closing of stomata and chlorophyll content of plant leaves. Research shows that the opening and closing of stomatal pores in crop leaves treated with cyclohexylamine is more coordinated and the chlorophyll content is higher.

Table 7 shows the effect of cyclohexylamine on crop photosynthesis efficiency.

4.3 Enhance stress resistance

Cyclohexylamine can enhance the stress resistance of crops by regulating the activity of antioxidant enzymes in plants. Research shows that crops treated with cyclohexylamine show stronger survival ability and growth potential under drought, saline-alkali and other stress conditions.

Table 8 shows the effect of cyclohexylamine on crop stress resistance.

4.4 Improve production and quality

Cyclohexylamine can improve crop yield and quality by regulating plant growth and development. Research shows that cyclohexylamine-treated crops have significantly increased yields and improved quality.

Table 9 shows the effect of cyclohexylamine on crop yield and quality.

5. Application cases

5.1 Application in wheat production

A certain wheat planting base used cyclohexylamine to treat seeds before sowing, which significantly improved the germination rate and seedling growth rate of wheat. Test results show that the root system of wheat treated with cyclohexylamine is more developed, the opening and closing of leaf stomata is more coordinated, the photosynthetic efficiency is improved, and the yield is increased by 25%.

5.2 Application in corn production

A certain corn planting base uses cyclohexylamine spraying during the growth period, which significantly improves the stress resistance and yield of corn. The test results showed that corn treated with cyclohexylamine showed stronger survival ability and growth potential under drought conditions, and the yield increased by 20%.

5.3 Application in soybean production

A certain soybean planting base used cyclohexylamine to spray during the flowering stage, which significantly increased the number of soybean flowers and pods. Test results show that the root system of soybeans treated with cyclohexylamine is more developed, the opening and closing of leaf stomata is more coordinated, the photosynthetic efficiency is improved, and the yield is increased by 30%.

6. Conclusion

Cyclohexylamine, as an important organic amine compound, is widely used in agricultural chemicals. Through its application in pesticides, fertilizers and plant growth regulators, cyclohexylamine can significantly increase crop yield and quality, promote root development, improve photosynthesis efficiency and enhance stress resistance. Future research should further explore the application of cyclohexylamine in new fields, develop more efficient agricultural chemicals, and provide more scientific basis and technical support for agricultural production.
