In addition to weeding, methylurea and its derivatives also show excellent plant growth regulation activity, which can promote crop growth and development by regulating plant hormone balance, improving metabolic activities.
The Role of Methylurea in Plant Growth Regulation
Mechanism of regulating plant growth
Hormone regulation: Methylurea can indirectly promote the synthesis or release of plant endogenous hormones (such as auxin and cytokinin) and stimulate cell division and elongation.
Enhance metabolic activity: accelerate plant growth by improving photosynthesis efficiency and nutrient transport capacity of plants.
Improve stress resistance: enhance the tolerance of crops to drought, high salt and low temperature.
Application of Methylurea in Main Crops
Rice
Promoting tillering: The number of tillers in rice treated with n methyl urea increased significantly, and the stem strength increased.
Improve stress resistance: improve the adaptability of plants to waterlogging and high temperature, and reduce lodging.
Wheat
Enhance cold resistance: Methylurea can be used in the winter of wheat to improve the frost resistance of plants and protect seedlings.
Increasing yield: By stimulating root development and improving grain plumpness, wheat yield is significantly increased.
Corn
Promote root development: Methylurea can promote the root growth of maize and increase the absorption capacity of water and nutrients.
Improve ear grain development: increase the number of grains and plumpness of corn ear, and finally increase the yield.
Synergism with fertilizer
When n methyl urea is used in combination with nitrogen fertilizer and phosphorus fertilizer, it can significantly improve the utilization efficiency of fertilizer and further promote crop growth.
Development Direction of Methylurea in Future Agriculture
Optimization of Green Chemical Process
Develop more environmentally friendly and efficient methylurea production processes, such as using renewable resources or biocatalysts, to improve sustainability.
Research and development of high efficiency and low toxicity derivatives
Through molecular design and modification, methylurea derivatives with higher efficiency and lower toxicity were developed to meet the development needs of green agriculture.
Application of precision agriculture
Combined with modern precision agriculture technology, methylurea preparation is combined with remote sensing, spraying robot and other technologies to improve application efficiency and reduce waste.
As an important pharmaceutical intermediate, methylurea has shown wide application potential in the production of rice, wheat, corn and other crops by virtue of its excellent performance in weeding and plant growth regulation. By continuously optimizing the production process and developing new preparations, methylurea will play a greater role in improving agricultural production efficiency, reducing environmental burden and promoting the development of green agriculture.
