Plant growth regulators are a class of chemical substances—synthesized artificially or extracted naturally—capable of modulating the growth and developmental processes of plants. Their core mechanism of action lies in mimicking or interfering with the signal transduction of endogenous plant hormones (such as auxins, cytokinins, and gibberellins)

as a plant growth regulator, Forchlorfenuron stimulates cell division and enlargement in garlic. Field trials have demonstrated that, when applied appropriately, it can increase the diameter of garlic bulbs by 15–20% and boost the weight of individual plants by approximately 30%.

Brassinolide is an endogenous steroidal plant hormone that was first isolated from rapeseed pollen in 1979 and was recognized by the scientific community in 1996 as the sixth major class of plant hormones. Characterized by its high efficiency, broad spectrum of activity

Sodium Nitrophenolates accelerate plant growth, break dormancy, and promote overall development. They prevent the shedding of flowers and fruits, as well as fruit cracking and shriveling; furthermore, they improve product quality, increase yields, and enhance crops' resistance to various environmental stresses—including diseases, pests, drought, waterlogging, cold temperatures, salinity, alkalinity, and lodging.

Diethyl aminoethyl hexanoate (DA-6) is a broad-spectrum plant growth regulator. It promotes crop growth, enhances cold and frost resistance, improves fruit quality, and boosts fertilizer utilization efficiency by increasing plant enzyme activity, enhancing photosynthesis, and facilitating cell division and nutrient balance.

These substances act more like "mood regulators" within the plant body—capable of driving explosive growth in some instances, while inducing calm dormancy in others. For instance, Gibberellic Acid (GA3) can cause dwarf pea plants to grow taller, whereas Abscisic Acid can trigger the premature shedding of fruit.

Chlormequat chloride is a widely used plant growth regulator, Its primary function is to inhibit excessive stem elongation in plants, prevent lodging, and promote crop dwarfing and yield enhancement.

Para-nitrophenol is a crucial organic chemical intermediate, primarily utilized in the synthesis of pharmaceuticals, pesticides, and dyes, while also serving as a reagent in analytical chemistry.

During the spring season, foliar application of the "Brassinolide + Monopotassium Phosphate + Fulvic Acid" golden formula combination can significantly enhance a crop's drought resistance, delay premature senescence, and promote grain filling to boost yields. It currently stands as a core technical solution for crops—such as wheat, maize, and vegetables—in their battle against spring droughts and dry-hot winds.
