What is the difference between plant growth regulators and plant growth agents?
In the production of pollution-free tea, how should pollution-free plant growth regulators be correctly selected? Use of regulators that promote bud and leaf growth. At present, the plant regulators widely promoted and applied in pollution-free tea production in China include brassinolide, BR-120 and Tianfengsu, etc. When these plant growth regulators are applied to tea plants...
A brief introduction to the difference between plant growth regulators and plant growth agents is provided for reference.Plant growth regulators. Plant growth regulators are pesticides, and there are strict requirements in their use technology, such as the period of use, dosage and method of application. They must be used according to the instructions, otherwise adverse consequences will occur. The effects of plant growth regulators are generally obvious and stable, and are less affected by environmental conditions, so they are promoted and applied quickly and are easily accepted by users. They are a class of organic compounds artificially synthesized with the activity of natural plant hormones. According to their different regulatory effects on crops, they can be divided into two categories: (1) those that promote growth, such as 920, 802 and ethephon, etc.; (2) those that control growth, such as paclobutrazol, chlormequat and mepiquat chloride, etc.
Plant growth agents. Plant growth agents are fertilizers, also called plant nutrients, plant compound liquid fertilizers, etc. They are a type of nutrient substance made by concentrating macroelements and microelements such as nitrogen, phosphorus, potassium, iron, zinc, manganese, boron and copper together, and are mostly used as foliar sprays to supplement nutrients and promote crop growth and development when crop roots absorb water and fertilizer poorly. Although plant growth agents have relatively good effects on crops, their use is highly selective in terms of environmental conditions, crop growth status and field management, and their effects are very unstable, so attention should be paid when using them.
