Soil problem, a major subject of modern agriculture!
In the first 10 years, our agriculture has been in the stage of continuous pursuit of yield. The frequent use of pesticides, fertilizers and regulators and the very common use of supersaturation have made our soil continuously deteriorate. Salt accumulation, pH value rise, hardening, epidemic diseases, pests and weeds are becoming more and more difficult to control, and even sitting obstacles have become difficult problems for us to solve.

More than 90% of the total output of summer grain is crucial to the production of summer grain. Cultivating strong seedlings before winter and ensuring safe overwintering are the key to building a reasonable population and laying the foundation for the number of ears, as well as the basis for grasping the field management next spring, promoting the upgrading and transformation of seedling conditions, and seizing the wheat harvest. All localities must attach great importance to it, make overall arrangements, strengthen leadership, mobilize extensively, take all effective measures, do a good job in the management of wheat fields before winter, and lay a solid foundation for a bumper summer harvest next year.

Research and application of plant growth regulators and their development in the next few years
Plant growth regulators are a kind of substances with similar physiological and biological effects to plant hormones. It has been found that the substances with the functions of regulating plant growth and development include auxin, gibberellin, ethylene, cytokinin, abscisic acid, brassinolide, salicylic acid, jasmonic acid and polyamines. As plant growth regulators, they are mainly used in the top six categories in agricultural production.

Research and Development Trend of Plant Growth Regulators
The mystery of life is attracting many scientists to constantly discover new plant growth regulators and summarize new theories, such as jasmonic acid, polyamines, moonlight, oligosaccharides, etc., which have been discovered recently, play a great role in regulating plants and will be new plant growth regulators. The new theory of genetic compartment information lays a theoretical foundation for explaining the popularization and application of plant growth regulators.

Pyridine is an important chemical intermediate
Pyridine is an important chemical intermediate, and pesticide is its largest downstream product, which can produce paraquat, diquat, chlorpyrifos, imidacloprid and other pesticides. Pyridine pesticides, as the fourth generation of new pesticides in the world, are not only highly efficient, low toxic, and have a long shelf life, but also have good environmental compatibility with humans and organisms, meeting the development requirements and trends of pesticides.
