1. Ampicillin DA-6
Acetate DA-6 is a high-energy plant growth regulator newly discovered by American scientists in the 1990s with broad spectrum and breakthrough effects. It can increase the activity of plant peroxidase and nitrate reductase, increase the chlorophyll content, speed up photosynthesis, promote the division and elongation of plant cells, promote the development of root systems, and regulate the balance of nutrients in the body.
2. Chlorfenuron
Chlorfenuron is a phenylurea plant growth regulator with cytokinin activity, but its biological activity is 10-100 times higher than that of 6-benzylaminopurine. It is widely used in agriculture, horticulture and fruit trees to promote cell division, promote cell expansion and elongation, promote fruit hypertrophy, increase yield, preserve freshness, etc.
3. Sodium nitrophenolate
Sodium nitrophenolate (also known as sodium nitrophenolate) is a powerful cell activator. Its chemical composition is sodium 5-nitroguaiacol, sodium o-nitrophenolate, and sodium p-nitrophenolate. After contact with plants, it can quickly penetrate into the plant body, promote the flow of cell protoplasm, and improve cell vitality.
4. Brassinoids
Brassinolide, also known as brassinolide, is a new type of plant endogenous hormone. It is recognized as a highly efficient, broad-spectrum, non-toxic plant growth regulator. It has strong penetration and rapid internal absorption. At a very low concentration, it can Significantly increases plant vegetative growth and promotes fertilization.
It can effectively increase the chlorophyll content, improve photosynthesis efficiency, promote root and seedling growth, preserve flowers and fruits; improve the cold resistance, drought resistance, salt-alkali resistance and other stress resistance of crops, significantly reduce the occurrence of diseases; and can significantly alleviate the risk of phytotoxicity. occurs, allowing crops to quickly resume growth and eliminate disease spots.
5. Gibberellin
Gibberellin is a widely existing plant hormone. The chemical structure belongs to diterpenoid acid, which is derived from a four-ring skeleton. There are at least 38 types of gibberellins, which are used in agricultural production to stimulate the growth of leaves and buds and increase yields.
