Scientific understanding of the application of plant growth regulators in agriculture
What is a plant growth regulator? People who are familiar with it think of it as a hormone and talk about discoloration. In fact, the substance is a chemical synthetic substance that is different from hormones. It is only similar in chemical properties, structure, and function to crop regulating substances. It has been widely used in modern agriculture in various countries of the world. It is a way to increase the output of agricultural products and improve their quality. However, due to its different nature, its toxicological mechanism and the safety period of residues, as well as the health and safety issues of humans and animals, have attracted the attention of many countries and experts. However, dialectical materialism tells us that everything has a degree, and once it becomes excessive, it will undergo a qualitative change.
Plant growth regulators are actually a kind of pesticides. It is one of the important measures for agricultural modernization to regulate the growth and development of crops, shorten the maturity of fruits and vegetables, increase production and improve quality. However, some farmers have used them improperly. For early harvesting, improving economic efficiency, blind use or abuse, the application fields of plant growth regulators are confusing. The residue of the substance in agricultural products has become a problem affecting the safety of agricultural products. Especially in the off-season production of fruits and vegetables are particularly prominent, some appear to increase in size, color change, flat taste, deformity of the fruit, quality is reduced, causing people to have such a doubt, vigilance, or even rejected the psychology of fruits and vegetables. Therefore, plant growth regulators must be applied scientifically and scientifically to ensure their safety.
According to the nature of plant growth regulators and their effects on plant physiological regulation, these substances are not fertilizers, but they can have a significant effect on the growth and development of plants at very low concentrations. If used improperly, they will produce different levels of drug. Harmful, especially synthetic compounds that belong to certain toxicities, but their toxicity is lower than other pesticides, such as butyryl hydrazide used in apples, the resulting metabolite dimethyl hydrazine is a potential carcinogen. Therefore, to ensure the safety of using food plants, these are important issues that people are concerned about.
With the development of science and technology and agriculture, plant growth regulators are used to regulate the growth and yield of plants, and these research applications have been used at home and abroad as one of the main measures for achieving the overproduction of agriculture in the 21st century. Especially in China, to meet the needs of modern agricultural development, high-efficiency, low-toxicity, broad-spectrum plant growth regulators have been widely used in the country. At the same time, as soon as possible, their genetic and genetic adverse effects are studied, and early detection of plant growth regulators on ecology and human and livestock. The potential hazards and mechanisms of toxic effects, the establishment of correct methods of use, establishment and improvement of relevant monitoring and evaluation mechanisms, and ensuring that Chinese agricultural products participate in international market competition with high quality are imperative. Therefore, the development of pollution-free plant growth regulators applied to agriculture is very necessary to protect the environment and improve the quality of agricultural products.
