Must be used according to the instructions, otherwise it will have adverse consequences. The effects of plant growth regulators are generally obvious and stable, and are less affected by environmental conditions, so they are popularized and applied quickly and are easily accepted by users.

(1) promoting growth, such as 920, 802, ethephon, etc.;
(2) Controlling growth, such as paclobutrazol, chlormequat, and ketamine. Plant growth agents Plant growth agents are fertilizers, also known as plant nutrients, plant complex liquid fertilizers, and the like. It is a kind of nutrient which is made by combining a large amount of nitrogen, phosphorus, potassium, iron, zinc, manganese, boron, copper and other trace elements. Most of the crop roots absorb leaf water and make leaf surface fertilizer to supplement nutrients. Promote crop growth and development. Although plant growth agents have good effects on crops, they are highly selective in terms of environmental conditions, crop growth, and field management, and their effects are very unstable. Attention should be paid when using them.
